General Information
As the main refractories for coke oven, the quality is the key of energy saving, high efficiency, environmental and time of usage on coke oven. Over the years, We has been provided high-quality silica bricks for steel plants at Nagoya, Muroran and Oita of Nippon Steel and the products quality have been proved world-class products.The excellent performance silica brick has the following characteristics. The low creep, high refractories under load and low residual quartz contents, silicon bricks for hot stove of our company has been successfully applied to various types of hot stoves of major steel companies at home and abroad and the quality has been recognized by the clients. The silica bricks are the main fire-resistant material of coke oven. In order to keep its high quality, we take the best silica as raw material from Liaoning Shimen, Shanxi Wutaimountain, Henan Tiemen. With the multistage batching and best grain matching, our semi-manufactured goods are produced by the 300tons bricks pressing machine. The bottom,
Wall and top bricks are produced by 500tons bricks pressing machine. Every semi-manufactured and finished product-s are examined according to the national standard and marked it according to the tolerance.
Feature
Superior resistance to acids (including oxidizing)
Resistance to chlorine
Resistance to thermal shock and pressure changes
Low thermal and chemical expansion

Photos for Applications
- Q: The hot blast stove when the temperature did not rise against the brick interface decreased
- Different insulation methods can be adopted according to the length of the stop time and the location and equipment of the overhaul. Gold, refractory material factory specializing in the production of various specifications of 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 acid refractory?
- Refractory materials are mainly quartz glass products, combined with fused quartz products, silica brick and unshaped refractories. Semi siliceous refractory materials are generally attributed to this category. As for fireclay refractories, they are also classified as semi acidic or weakly acidic refractories. Also, zircon refractory and silicon carbide refractory for special acidic refractory materials are also classified into this category.
- Q: The brick is mainly used in the place?
- Open hearth furnace regenerator and a sediment chamber, soaking furnace, glass furnace refractory materials and ceramic brick kiln, kiln vault and other load-bearing parts.
- Q: The United States of our brick anti-dumping duties?
- At present of our brick anti-dumping rate is 73.10%
- Q: How to judge the quality of brick, clay brick, high alumina brick furnace from the appearance?
- Mainly depends on the color and density of brick. Another black clay brick and brick with iron oxide formation and how much the size of bricks
- Q: How to improve the thermal conductivity of the coke silicabrick rate?
- The content of SiO2 is 98.23% crystalline silica as raw material, with sulfite pulp liquid as binder, millscale and lime as mineralizer, by Jin Hongshi (TiO2) as additive, can improve the rate of thermal conductivity of silica brick for coke oven. When the rutile content is 1.5%, the coefficient of thermal conductivity of silica brick for coke oven is 2.66W/ (m.k).
- 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.
- Q: Why in the production of the brick to detect the volume density
- Density is the property of material, different density of materials, density of the same kind of material is not up to standard, affecting performance.
