$Refractory Brick Silica Brick For Hot Blast Oven Brick$

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: The main damage of silicon carbide side wall brick is stress damage, not chemical erosion. Chemical damage is formed prior to the formation of the groove, and the damage to the chemical erosion is little after the formation of the groove.

Q: Semisilica brick interpretation: Good thermal shock resistance. In use, more high viscosity glass phase can be formed, and the masonry brick joint and the working surface are dense and the masonry is complete, which is beneficial to improve the impermeability of the masonry and reduce the erosion effect of the slag on the masonry.

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: 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: 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: The United States of our brick anti-dumping duties?: . According to the relevant legal procedures, the United States International Trade Commission will make a final ruling on the anti dumping industrial injury before January 6, 2014, if an affirmative determination, the U.S. Department of Commerce will be involved in product release tax anti-dumping order.

Q: Can not use it two brick: Acidic silica brick refractory material, has good ability in acid slag erosion

Q: The chemical composition of silica brick and its physicochemical index?: ????Al2O3 SiO2??????fe2o3??????cao???????r2o93～98?0.5～2.5?；；?0.3～2.5??0.2～2.7；??1～1.5；
