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 from the impurities to determine how much, generally less impurity single color brick.

Q:Glass kiln brick for physical and chemical indicators?

Glass kiln with high quality silica brick products according to the standard JC/T615-1996, the single brick is divided into 3 grades: XBG-96, ZBG-96, DBG-96.

Q:Common bond brick?

Lime should contain a lot of active CaO, I decompose CaCO3 and MgCO3 not more than 5%, Al2O3+Fe2O3+SiO2 no more than 5%. When the content of large particles, burned Ca-CO3 and over burned lime, the product produced caves, affecting the quality of products.

Q:Why is the new trend of the high thermal conductivity of silica brick

The use of high thermal conductivity of silica brick, reducing coke fuel consumption, reduce emissions of pollutants such as NOx, with considerable economic benefits and social benefits, is the future direction of the new technology of using coke oven refractory.

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.

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:Such purpose and scope please give me detailed points thank you

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

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: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
