. 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:What is the silica refractory products?

Refractory brick with silica content greater than 90%.

Q:High temperature refractory material?

Basic refractories in Magnesium Oxide and calcium oxide as the main component, the main products are magnesia brick, magnesia chrome brick, magnesia zirconia brick, magnesia brick, magnesia spinel brick, magnesia calcium brick, dolomite brick and the latest development of magnesia spinel brick and so on. With Magnesium Oxide (MgO) more than 80% of the refractory brick called magnesia brick,

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: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:The difference between clay refractory bricks and refractory brick in the application.

Clay brick features good thermal shock resistance and low price, but high temperature performance is not well integrated, and the long-term use temperature is not higher than 1300 degrees. It is widely used in low temperature parts of various kilns.

Q:The specific content is what gb/t2608-2012 brick

The provisions of the brick classification, technical requirements, test methods,

Q:Brick

Acidic silica brick refractory material, has good acid resistance and slag erosion, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature.

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:Such purpose and scope please give me detailed points thank you because I am learning stage

Acid refractory brick is mainly composed of tridymite and cristobalite and quartz and a small amount of residual glass phase.
