$Glass Furnace Application Refractory Silica Brick$

Q: Common bond brick?: When adding ingredients, the amount of lime added shall be converted to CaO, and the amount of addition varies depending on the product, usually fluctuating at 1.5~2.5%. For example, the production of coke oven silica brick, the dosage of CaO is 2.0~3.0%; the production of electric furnace top brick, the dosage of CaO is 1.4~1.75%.

Q: The specific content is what gb/t2608-2012 brick: The provisions of the brick classification, technical requirements, test methods,

Q: What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you: Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.

Q: The introduction of silica brick: The characteristics of silica brick:Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.The use of silica brick:Mainly used for masonry brick oven carbonization chamber, a combustion chamber and a partition wall, glass furnace and kiln roof, pool wall, high temperature hot blast furnace, glass furnace, load-bearing pool wall, hot blast stove, baking furnace of carbon bearing part of high temperature furnaces etc.. Rongsheng with refractory

Q: The difference between clay refractory bricks and refractory brick in the application.: The ability of alkali resistance is poor, the thermal shock stability is the worst, and it is scrapped at one time. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.

Q: What is the main material of silica brickIt's common, the kind we see so often!: An acid refractory consisting mainly of quartz and square quartz and a small amount of residual quartz and glass.

Q: Semisilica brick, clay brick, high alumina brick and what is the difference?: This is a kind of refractory material is divided into three types: semisilica brick (A12O315 ~ 30%), clay brick (A12O330 ~ 48%), high aluminum brick (A12O3>48%).

Q: Can iron oxide be used as refractory material?: Iron oxide can not be used as refractory material, but it can be used as refractory additive. Iron oxide can be used as pigment

Q: What are the main constituents of refractory bricks?: Clay brick and clay brick are mainly composed of mullite (25% ~ 50%), glass phase (25% ~ 60%) and square quartz and quartz (up to 30%). Usually with hard clay as raw material, pre calcined mature material, and then with soft clay, semi dry or plastic molding, the temperature at 1300~1400 C fired clay brick products. Can also be added a small amount of water, glass, cement and other binders to make non burning products and amorphous materials. It is a refractory brick commonly used in blast furnaces, hot blast furnaces, heating furnaces, power boilers, lime kilns, rotary kilns, ceramics and refractory bricks.

Q: Physical solid waste disposal: Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.
