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: Physical solid waste disposal
- The production of silicon material is added to the cause of waste brick:Preparation of silica brick pug, a certain amount of waste silica brick used to add ingredients, for the purpose of expansion and stress reduction products during firing
- Q: Which material is good for furnace refractory?
- Neutral refractory is mainly composed of alumina, chromium oxide or carbon. Corundum products containing more than 95% of alumina are a kind of high quality refractory materials with a wide range of uses. Chrome brick with chromium oxide as its main component has good corrosion resistance, but its thermal shock resistance is poor, and its deformation temperature is lower at high temperature. Carbon refractories with carbon bricks, graphite and silicon carbide products, low coefficient of thermal expansion, high thermal conductivity, good thermal shock resistance, high strength, resistance to acid and salt corrosion, especially weak acid has good resistance, without wetting of the metal and slag, light. It is widely used as lining material of high temperature, and also used as lining of autoclave in petroleum and chemical industry.
- Q: Can iron oxide be used as refractory material?
- Iron oxide can not be used as refractory material, but it can be used as refractory additive. Iron oxide can be used as pigment
- 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: How to improve the thermal conductivity of the coke silicabrick rate?
- To improve the thermal conductivity of silica brick for coke oven rate method:Manufacture of high density and high thermal conductivity of silica brick, adding additives such as CuO, Cu2O, TiO2, Fe2O3, (FeO), can improve the thermal conductivity of silica brick.
- Q: Why is the highest brick coke oven temperature measuring point temperature not exceeding 1450
- Brick belongs to refractory materials, with strong resistance to acid slag or acid solution erosion ability, high load softening temperature are excellent properties of silica brick, usually 1640-1680 C.
- Q: The chemical composition of silica brick and its physicochemical index?
- Brick refers to the refractory products in more than 93% of the content of SiO2
- Q: What is the silica refractory products?
- Refractory brick with silica content greater than 90%.
- 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.
- Q: The formula in the refractory brick, and firing curve, who knows?
- Add 1.8-2.2% of the total weight of the main raw material, and then add lime milk, rolling for 10-15 minutes, and finally add pulp, rolling for 10-15 minutes, out of the mill, forming billet.
