Characteristic Refractory Material Mud Mixing Method

Characteristics of refractory material mud mixture method is to produce special refractory products, in particular the use of gypsum injection molding, casting and injection molding molding of the mud slurry f operation method is the ingredients of various refractory raw materials, enhancers, Suspending agent, admixture and 30 ~ 40% of the clean water, while adding a wear-resistant lining in the ball mill (mixing mill), after a certain period of mixing fine grinding, made for the production of mud slurry. In the process of making mud, according to the characteristics of materials and mud pouring their own requirements, to control the density and pH of the mud.
Mud mixing method used by the main equipment are ball mill, air compressor, wet iron, mud pump, vacuum degasser and so on.
Paraffin and resin-based binder, at room temperature for the solid refractory materials (or into a sticky), at room temperature, especially law mixture, must be used to increase the method of heating.
The use of hot casting process, the use of paraffin as a binder. Due to the melting point of paraffin in the 60-80 <€, in the first paraffin heated to 100T or more and have good mobility, and then the fine powder raw materials added to the liquid paraffin, the mixing after mixing, made of slurry Wax cake for hot die casting.
The main mixing equipment for heating the mixture is a heated mixing mixer.

The use of refractory materials in the metallurgical industry

refractory materials

Insulation Refractory material refers to refractory materials with high porosity, low bulk density and low thermal conductivity. It features a porous structure (typically 40% to 85% porosity) and high heat insulation.

Insulation refractory material used as the furnace insulation layer, lining or insulation layer, can save fuel costs. More types, mainly light refractory products, heat insulation and refractory materials and their products.

Lightweight refractory products

The main light of silicon refractory brick, light clay brick, light high alumina brick and alumina hollow ball products. Usually the weight of light refractory products is usually 0.6-1.2g / cm3, the use of temperature is usually 900 ~ 1350 Yi. Alumina hollow ball products can be used in the following long-term use.

2 refractory fiber and its products

Refractory fiber is a fibrous refractory material, is a new type of high efficiency insulation products. The main production method of refractory fiber is melt blown method, high speed centrifugation and colloid method.

Refractory fiber The main types of aluminum silicate refractory fiber, zirconium aluminum silicate refractory fiber, high purity high alumina refractory fiber, polycrystalline mullite fiber, alumina fiber, zirconia fiber and so on. In addition for low-temperature insulation of the slag cotton, glass fiber and so on. Refractory fiber products are refractory fiber as the primary raw material, processed by the various blankets, felt, board, rope, paper and other high-temperature insulation materials.

Refractory fiber products with small bulk density, low thermal conductivity, thermal stability and resistance to mechanical sensation. Refractory fiber products only 0.1 ~ 0.2g / cm3 bulk density. With fire-resistant fiber products do kiln lining, heat loss is small, saving fuel, heating up fast, especially for intermittent work furnace. In addition, fire-resistant fiber also has a soft, easy processing, construction and other characteristics. At present, the production and use of refractory fiber has been rapid development, metallurgical and other industrial enterprises demand for refractory fiber more and more urgent. After the use of refractory fiber, the energy saving effect is obviously improved.
