Refractory materials for glass furnaces

Refractory materials

There are three key drivers behind the evolution of refractories: maintaining improved glass quality; economic requirements on glass kilns to make kilns run longer and impact after pure oxygen combustion systems.
The word "current" can be read in months or even weeks as the computer industry in the electronics industry changes. When it comes to the development and application of refractories in the glass industry, it can easily be read as five or ten years. Based on this notion of time, we will recall that there has been a change in the discussion of the "current" area (more conservatively) in the latter area.
There are three major driving forces behind the development of refractory materials. The first glass manufacturer typically needs to improve glass quality in order to maintain it at least. The second glass kiln economy required a longer kiln operation cycle and a third pure oxygen combustion system with impact. These three requirements usually determine the choice of improved refractories when repairing the kiln. These impetuses have also prompted the glass manufacturer to use the furnace with improved fire-resistant products for maintenance and repair, as well as the introduction of new technologies for a wide range of maintenance runs.
Melting-cast alumina bricks have been melting pool top this part of the establishment of its application, the main melting high-quality glass pure oxygen combustion furnace was applied. Prior to the advent of pure oxygen combustion technology, only beta alumina bricks were used to melt pool superstructure and no melt cast alumina bricks were used on top of the melting pool. Today, both β-alumina and α-β alumina melt-cast products are used to produce color TV (screen cone), float glass and borosilicate glass pure oxygen combustion furnace some or all of the roof. Melt-cast AZS bricks can typically be used at 1600 ° C or 1650 ° C (depending on the glazing), while furnace tops with fused alumina are successfully operated at 1700 ° C. This gives glass manufacturers greater flexibility when creating refractory glass.
For many years, melt-cast AZS roofs have successfully undergone a cooling and reheating test to enable them to use multiple operating cycles. There is now a bit of experience in the successful implementation of top cooling and reheating of fused-alumina roofing, demonstrating an economically viable life when they use two or more cycles of operation. The results of fused alumina furnace roof observation (thermal observation and shutdown) show that these materials are both chemically and mechanically stable. This was the earliest observation of this type of masonry study since there was neither a fused alumina reference nor the empirical basis of its roof application.
High-chromium refractory products used to be mainly used to enhance the glass furnace, and a small amount used in insulation glass pool furnace. High chrome bricks are increasingly being used by some soda lime glass furnaces. Its main use has not only been limited to all or part of the flow hole, but also for the end wall and to a limited extent for the filler brick. For high chrome brick components, they are potentially dangerously colored, so that high-chromium products are often not compatible with very "white" glass. In the initial period this product was mainly used for colored glass, but high chromium products have also been successfully used in transparent container glass furnaces. The use of high-chromium glass furnaces depends largely on the design of the liquid hole, the cooling of the liquid hole, the daily production of the furnace, and the operation of the furnace. A glass manufacturer may use high-chrome bricks for the entire cover plus the melting tank end wall. High Chromite brickwork liquid caves offer the potential to increase kiln life because this material provides at least twice as much resistance to most glass as molten AZS bricks. However, some design parameters differ from those of fused AZS bricks and need to be discussed with the supplier.

Residual Heat Utilization of Refractory Gas Burning Kiln

Refractory

With the gradual implementation of the national environmental protection policy, the original domestic coal-fired kiln in the refractory industry is about to end its historical mission and replace it with clean natural gas, liquefied gas, light diesel oil, city gas and producer gas as the main New energy kiln. However, China is a large coal producing country, and refractory material are also large energy-hungry households. Some medium-to-low-grade refractories and large-volume refractories are still controlled by the furnace hot gas to ensure fuel supply and production cost control . As a result, the refractory industry has also developed a hot gas tunnel kiln, hot gas intermittent plutonium kiln group, hot gas intermittent shuttle kiln group.
Due to the different kiln body structure and thermal engineering process, intermittent kiln produces 5 times more flue gas than continuous kiln production. In general, the higher the gas temperature, the greater the proportion of heat loss. If the gas temperature is 1093 ℃, the heat loss reaches 55%; when the gas temperature is 1427 ℃, the heat loss reaches 70%. For the firing of refractory hot gas intermittent inverted kiln, according to the relevant experimental data show that: flue gas away from the kiln away from the heat about the furnace total heat expenditure of 35% to 40% in the absence of any heat recovery In the case of the measure, the heat balance calculation results, the thermal efficiency is only 10% ~ 15%. This is a big heat loss. Therefore, the use of flue gas heat is a very important energy recovery.
Set the heat exchanger in the flue is an important means of waste heat recovery. The hot air obtained after the heat exchange can be directly sent to the burner for combustion air, or the hot air can be diluted to the drying medium of the product embryo drying kiln or used to make the thermal efficiency of the kiln reach 30% or higher.
When the firing system uses a heat exchanger to preheat the air and use this hot air to make the combustion-supporting combustion air, the thermal efficiency of the kiln can be improved, the fuel consumption can be reduced, and the energy-saving effect can be achieved. And in the organization of high temperature combustion flame temperature can increase, increase heating efficiency, shorten the heating time (firing cycle). And because the hot air volume expansion, resulting in the burner orifice flow rate increases, accelerating the kiln gas circulation, contribute to the kiln temperature uniformity. The data show that: when the preheated air temperature reaches 220 ~ 250 ℃, can reduce fuel consumption by 6% to 8%. At the same time different combustion temperature, the impact on the flame temperature is very large. Even when the gas is not preheated, the combustion temperature of the gas increases significantly as the preheating temperature of the combustion air increases. This not only can solve the problem of low firing temperature, but also plays an important role in saving energy and reducing consumption.
In intermittent kiln production, because the fuel is changed with the heating stage, the amount of flue gas generated by the fuel also changes. In the event of a large fire, since the amount of fuel per unit time increases, the flue gas and temperature also inevitably increase. Preheat air combustion just to meet the requirements of combustion. Metal pipe heat exchangers are commonly used in production. Due to the limitations of high temperature oxidation and mechanical properties, the maximum service temperature is generally limited to below 500 ° C because of their low life (about 0.5 years). Metal pipe aluminum treatment, its service life is only about a year. The use of heat-resistant stainless steel or heat-resistant cast iron, the maximum temperature is generally limited to below 900 ℃. However, due to its high price, the use of units unbearable.  1. Because the fuel is the producer gas, the chimney bricks will not block. Life can be more than 10 years. Designed to ensure that the heat transfer efficiency, heat transfer area as large as possible (such as a group of 4 × 200m3 Square inverted hearth heat exchange area of ??about 230m2), although the volume is large, but the site conditions permit a one-time investment in the province, the flue System resistance is generally about 147 ~ 196Pa, chimney can be selected according to the height (usually about 50m).

The use of heat exchanger temperature is a very important factor in heat recovery. If the flue gas temperature is 1315 ℃, the use of thermal efficiency of 60% ceramic heat exchanger can save about 48% of fuel, if the use of thermal efficiency of 60% metal heat exchanger, you must first add cold air flue gas temperature dropped to 815 ℃ below, so that only 24% of fuel savings. Table 1 shows the effect of blending cold air on fuel economy.

In order to play the respective advantages of ceramic and metal heat exchangers, the two are used in tandem, known as a hybrid heat exchanger. First high-temperature flue gas into the ceramic heat exchanger, flue gas temperature dropped to below 815 ℃, and then into the metal heat exchanger. The flow of cold air is first into the metal heat exchanger, the heated air and then into the ceramic heat exchanger for further heating, the final preheated air temperature up to 1093 ℃.

The difference between insulation material and refractory material

refractory material

There are many kinds of insulation products, including foam, mineral cotton products, foam glass, expanded perlite insulation products, EPS powder EPS insulation film, mineral spray cotton, foam cement insulation products. Selection of insulating materials in the construction of the common types of applications and design selection should be consistent with GB / T 17369-1998 "building insulation materials, application types and basic requirements" requirement.
In addition to the material should consider the thermal conductivity of the material, but also should consider the material of water absorption, combustion performance, strength and other indicators. The performance characteristics of different insulation materials see the corresponding classification guide.
Refractory material refractoriness of not less than 1580 ℃ of a class of inorganic non - metallic materials. Refractory degree refers to the refractory cone specimen in the absence of load conditions, resistance to high temperature effect without softening the melting of the Celsius temperature. Refractory materials are widely used in the metallurgical, chemical, petroleum, machinery manufacturing, silicate, power and other industrial fields, the largest in the metallurgical industry, accounting for 50% of the total output of 60%.
Frequently used special materials are AZS refractory brick, corundum brick, directly combined with magnesia-chrome brick, silicon carbide brick, silicon nitride combined with silicon carbide brick, nitride, silicide, sulfide, boride, carbide and other non-oxide refractories ; Calcium oxide, chromium oxide, alumina, magnesium oxide, beryllium oxide and other refractories. Frequently used insulation refractory abrasive
Refractory materials are diatomite products, asbestos products, thermal panels and so on.

Insulation material is used for building envelope or thermal equipment, the heat transfer of the material or material complex, including both insulation materials, including cold materials. Insulation brick on the one hand to meet the building space or thermal equipment, the thermal environment, on the other hand also saves energy. Therefore, some countries will be adiabatic materials as coal, oil, natural gas, nuclear energy after the "fifth largest energy." A material with a strong resistance to heat flow. Mainly used for housing construction of the wall, roof or industrial pipes, furnaces and other insulation and insulation. According to the principle of insulation is divided into:
① porous material. The gas with a small thermal conductivity is filled with adiabatic pores. Generally the air is the thermal resistance medium, mainly the fibrous aggregation organization and the porous structure material. Foam plastic insulation is better, followed by mineral fibers (such as asbestos), expanded perlite and porous concrete, foam glass.
② Reflective material. Such as aluminum foil can rely on thermal reflection to reduce radiation heat transfer, a few layers of aluminum foil or paper with a thin layer of composite structure, can also increase the thermal resistance. Insulation materials are often used in the form of loose materials, coils, plates and prefabricated blocks for the insulation and insulation of roofs, facades and floors of buildings. Can be directly masonry (such as aerated concrete) or on the roof and envelope for the core material, but also paved into the ground insulation layer. Fiber or granular insulation material can be filled in the wall, can also be sprayed on the wall, both adiabatic, sound absorption, decoration and fire and other effects.

Refractory materials for different parts of electric ARC furnace(1)

Refractory materials for different parts of electric ARC furnace

(1) Refractories for ARC furnace roof
Electric Arc Furnace life refers to the life of furnace roof. After the 1980s, with the expansion of steel-making electric arc furnace capacity and the increase of unit power, the working conditions of the furnace roof become more demanding, the refractories used for electric Arc furnace also changed.

The roof of arc furnace commonly use high alumina brick to masonry, Al2O3 content of between 75% to 85%. Compared with silica brick, the characterized of high alumina brick is high refractoriness, thermal shock resistance, good slag resistance, high compressive strength. Because of its high thermal shock resistance and structural integrity, it is not necessary to produce shaped bricks. There ie a rich bauxite resources in China, high alumina insulating brick has become the main refractory material on Arc Furnace roof, its life is 2 to 3 times of silica brick roof . With the development of large-scale ultra-high-power electric furnace, the service life of high-alumina brick is reduced, Leading to the further use of calcined or not burning magnesia brick and magnesia-chrome brick and other alkaline brick.

(2) Refractories for ARC furnace wall
The furnace wall is divided into general furnace wall, slag line area and hot spot that near the arc . The main furnace wall mainly uses the magnesia brick, the tar pitch combination and the asphalt impregnation burns the dolomite brick and the magnesite refractory brick masonry, also has uses does not burn the magnesia alkaline brick and the asphalt union magnesia and the dolomite ramming material, That all have longer service life. ARC furnace wall which Ultra-high power or smelting special steel used the magnesia-chrome brick and high-quality magnesia brick to masonry.

Slag line area and the hot spot of furnace wall is weak link. As the furnace wall life depends mainly on the degree of damage of hot spot, so the parts of lining should be special attention. the 20th century 70 years ago, the masonry of the site commonly used cast magnesium chrome bricks, combined with or re-combination of magnesia- chrome brick, the service life is 100 to 250 furnace times. Into the 80's, in these parts widely used magnesia carbon bricks
 to masonry, showing that in addition to high temperature and slag resistance performance,service life be significantly improved , the high-power electric arc furnace to more than 300 times in China.
