Q: What kind of fused corundum corundum brick should be used for each part of the glass furnace?: AZS33 is the casting of AZS series of the largest, most widely used in tea, to prevent the pollution of liquid glass is excellent. Widely used in the glass furnace pool wall, pool bottom, the upper structure and feeding routes and other parts.

Q: How much is a refractory brick?: There are many kinds of refractory bricks, you have to look at what is material, the material is not the same, the price is not the same, clay brick is the cheapest, probably hundreds of dollars a ton, and corundum brick a ton of several money, silicon carbide, silicon nitride, and more expensive. And this thing is generally on t sell, the price is by a single block after conversion.

Q: What are the advantages of refractories?: The castable refractory is a refractory product with a certain shape after being melted at high temperature by a certain method. Neutral refractory is refractory material which is difficult to react with acid or alkaline slag at high temperature, such as carbon refractory and chrome refractory. Some of the high alumina refractories are also attributed to this category.

Q: Which is good, glazed brick and whole cast glazed brick?: Vitreous tile is all ceramic tile, the material is hard, strong wear resistance, smooth finish is very good, in general, looks very bright. Microcrystalline brick, corundum brick Market said, they really mean bohuazhuan. Because of its low water absorption and high strength and hardness, glazed tile has been widely used. Many hotels, shopping malls and office space are widely used glass tile.

Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?: For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.

Q: What is the difference between corundum and high alumina?: The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.

Q: High temperature refractory material?: Many kinds of refractory materials, usually by refractoriness level is divided into ordinary refractory materials (1580 to 1770 DEG C), advanced refractories (1770 to 2000 DEG C) and special refractories (more than 2000 DEG C); according to the chemical characteristics into acid refractory material, refractory materials and basic refractory materials. In addition, the refractory material used for special occasions.

Q: Ask for help about the phase of refractory material: Binding phase. The binding phase is the phase outside the main crystal phase or the main crystal phase and the sub crystalline phase. The binding phase can be made up of either a fine crystal or a glass phase or a composite of the two. Such as the combination of magnesia brick, magnesia chrome brick, magnesia brick and other basic refractories in phase is composed of crystal matrix; silica brick, clay brick is made of glass phase in the form. When the matrix is formed at high temperature, the liquid phase is low, and the viscosity of the liquid phase is low and the quantity is large, the production and properties of refractory products are essentially controlled by the substrate.

Q: What is the difference between T3 refractory bricks and high alumina refractory bricks?: High aluminum refractory brick brick is all in one type of material classification, the material is AL2O3 high bauxite content above 55%, refractory brick by material into clay bricks, high aluminum brick brick brick corundum brick

Q: What are the refractory materials?: Not a good answer. You can sort out, such as: neutral, alkaline, acid refractory. Different kinds, of course, raw materials are different.For example: MgO-C brick basic refractories: magnesia (fused, high purity graphite) + + + phenolic resin additives (silica fume or aluminum or silicon carbide or high temperature asphalt) etc..
