Q: The introduction of silica 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: 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: Semisilica brick interpretation: High temperature volume stability. Volume change is small.

Q: How much is the highest melting point of silicon?: Acidic silica brick refractories, softening temperature is as high as 1640 to 1670 DEG C, in the long-term use volume is relatively stable under high temperature. More than 94% silica content.

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: What role does silica play in refractories?: Low fractory refers to the alumina content between 10%~30%, SiO2 content is less than 85%, semisilica brick SiO2 = 65%,The SiO2 content of not less than 93%, refractory material to natural quartz rock as the main raw materials are called silica, silica brick, silica brick, quartz glass and special products. China's literature generally put this type of product is called "siliceous refractory products", which is the most important brick.

Q: The United States of our brick anti-dumping duties?: At present of our brick anti-dumping rate is 73.10%

Q: Can iron oxide be used as refractory material?: Is widely used in this area. Mentioned refractory material of high school textbooks generally refers to three two aluminum oxide (alumina), alumina is also used as a refractory material, refractory crucible, porcelain, artificial gemstones.

Q: The difference between clay refractory bricks and refractory brick in the application.: Brick bearing soft temperature and close to the melting point, high temperature strength, can be in high temperature (above 1400 degrees) under the condition of long-term use, but the anti alkali erosion ability, thermal shock stability is the worst, a scrap. The brick is generally used in the coke oven, glass kiln. Other industries basically do not use.
