$Refractory Silica Brick High Quality$

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: What is acid refractory?: Acid refractory material usually refers to refractories with SiO2 content greater than 93%. Its main characteristic is that it can resist acid slag corrosion at high temperature, but it is easy to react with alkaline slag.

Q: The brick is mainly used in the place?: Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.

Q: How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?: Mainly from the impurities to determine how much, generally less impurity single color brick.

Q: The high thermal conductivity of silica brick and traditional brick what is the difference?: Brick, high thermal conductivity has been greatly improved in terms of morphology, crystal structure, physicochemical index. The structure and morphology of high thermal conductivity of silica brick,Structure and morphology of high thermal conductivity and the traditional brick brick magnified 20 times were compared, high thermal conductivity silica pore size distribution is more uniform and finer.

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: Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450: That is because the brick load softening point the maximum temperature is 1450 degrees.

Q: The chemical composition of silica brick and its physicochemical index?: The physicochemical index of silica brick:Turn left to |

Q: What is the silica refractory products?: Refractory brick with silica content greater than 90%.

Q: Such purpose and scope please give me detailed points thank you: Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.
