Introduction to the level classification of the Ceramic proppant

Refractories Ceramic proppant is used for oil deposit, which can improve oil output evidently. When putting in the gap of rock formation, which can show high diversion quality and increase oil output.
According to different raw material , there are several different level products:

1, Bauxite ceramic proppant is made from high quality bauxite and coal ash, which holds high refractoriness, high pressure reisistance and strong diversion. Bauxite ceramic proppant is environment friendly product, which is the most popular proppant in the world.
2, Fly ash ceramic proppant is made from solid rejected material and then mixed with water and cementitious matter, whose size is more than 5mm.

The Best Refractories for Induction Furnace -- 25+ Heats Silica Ramming Mass

In recent years, silica ramming mass is widely used in induction furnace. Compared with traditional refractory lining material, this product is of lower cost, shorter sintering time and better working condition. 


To offer clients better refractory products, we have successfully developed our 25+ heats silica ramming mass. As per actual working, we summed up the material consumption as following.
1. First heat: 10-15mm
2. Rest heat: 3-5mm


As per our experience, we should leave 70mm as save level. So if the lining thickness is 180/300/450mm, we could promise the least service life of our refractory material to be 25 heats. If the working condition is convenient, 30-40 heats is no problem.


 Furthermore, our silica ramming mass can also be applied in tundish and ladle. Service life can namely be 48-60 hours/ 200+ heats. 


Because of the great advantages as above, our silica ramming mass is very welcomed by our clients all over the world say Bangladesh, Ghana, South Africa, and Indonesia, etc. If more interests, please feel free to make us informed, our professional teams are ready to give you our reliable service. For new clients, we would offer more preferential as following.
1. Lower price trial order
2. Professional refractory technicians overseas service


Therefore, what are you waiting for? Talk your phone and call us!

How to Choose Refractory Bricks Used for Different Parts of Blast Furnace

Mainly used for coke oven, hot blast stove, acid steelmaking furnace and glass melting furnace. The products can be manufactured according to customers' different requirements.

 How to use Refractory let it has anti damage ability? The development of matching with refractory material according to the clinker rotary kiln each work with the different mining conditions, in a targeted manner to configure different anti damage of refractory materials, and considering the basic matching problem of each work tape lining service life, reduce maintenance times to stop the kiln, each work with lining, reach namely damage resistance independent and phase the purpose of matching cycle. Lining material preheating zone selection of good chemical stability, alkali erosion leaf wax stone brick and strong, the high siliceous raw pyrophyllite with low alkali, alkali resistant bricks made of this raw material, whether or not to burn the Chengdu firing with alkali resistance strong, but the strength is high, nearly doubled than clay brick life.
    The completion of the industrial experiment stage in Krivoy Rog coking plants, coke oven masonry and recommended room three thermal repair methods: flame gunning; using oxygen to the ceramic welding; using the exothermic material (heating material) to repair. The process principle of common: with the help of heat generated to form a protective layer on the surface of refractory composite masonry mending surface.
    Flame gunning method of flame gunning refractory products, powder particles melt in the liquid or gaseous fuel flame, and was sent to the surface to be repaired. At this point the masonry was nozzle flame supplementary heating, so using this method may not have special restrictions on temperature is put forward in this paper, and can adopt refractory powder cheaper to obtain high-quality gunning layer. Principle of ceramic welding method is adding to the material of strong oxidant (exothermic material) - aluminum and silicon. Wind transport by means of oxygen jet flame method, oxidant and refractory powder to the surface to be repaired.
