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:Why in the production of the brick to detect the volume density
- Product quality control of silica brick.
- 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?
- The natural mineral of silica is called quartz. In refractories, silica and siliceous refractory materials contain more silica. Silica is acidic at high temperature, and siliceous refractory can resist acid slag corrosion
- Q:Why is the three oxidation of two silicon is very harmful impurities in silica brick
- Can generate the material needs is the best way to see the impurity problem!! the first consideration is whether can get the material impurities with what method choice after the time! Miscellaneous reactions cannot have new impurity formation! Selected cannot and need material reaction reagent!
- Q:Such purpose and scope please give me detailed points thank you
- Mainly used for coke oven carbonization chamber and the combustion chamber wall, 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. Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.
- 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 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:The specific content is what gb/t2608-2012 brick
- Quality assessment procedures, packaging, marking, transport, storage, and quality certificates. Suitable for siliceous refractory bricks.
- 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:Can not use it two brick
- Acidic silica brick refractory material, has good ability in acid slag erosion
