Q:The United States of our brick anti-dumping duties?: . According to the relevant legal procedures, the United States International Trade Commission will make a final ruling on the anti dumping industrial injury before January 6, 2014, if an affirmative determination, the U.S. Department of Commerce will be involved in product release tax anti-dumping order.

Q:What are the main constituents of refractory bricks?: (a) containing refractory brick brick, refers to more than SiO293%, is the main varieties of acid resistant brick. It is mainly used for coke oven building, also used in furnaces all kinds of glass, ceramic and carbon calciner, refractory brick arches and other load-bearing parts, is also used in high temperature bearing part of hot blast stove, but should not be used in thermal equipment below 600 DEG C and the temperature fluctuation in the.

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.

Q:Physical solid waste disposal: The amount of addition is related to the shape and weight of the brick. The bricks can be added to 20% weight less than 25kg; bricks above 25kg can be added to 30%; for the specific type of brick can be added 30%. into waste silica brick should pay attention to this problem

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:What is the effect of the content of silicon nitride in silicon nitride bonded silicon carbide brick on the use of electrobath? Thank you: Small fluctuations in the chemical composition do not have a significant effect on use. The key is the operation of the electrolyzer in production to determine whether the side wall will be damaged.

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:Such purpose and scope please give me detailed points thank you because I am learning stage: 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. The silica mineral phase is mainly composed of tridymite and cristobalite, there is a small amount of quartz and glass. Tridymite and cristobalite and quartz remaining at low temperature due to phase change, volume changes greatly, so the brick thermal stability at low temperature is very poor. In use, under 800 degrees Celsius, slowly heating and cooling, so as not to produce cracks. The use of temperature in blast furnace so should not be below 800 DEG on. The properties and process of silica crystal with SiO2 transformation is closely related, therefore, the proportion of it is one of the important quality indexes of silica brick. General requirements below 2.38, high quality silica brick should be less than 2.35. The true density is small, reflecting a large number of scale quartz and square quartz in the brick, the residual quartz is small, so the residual line expansion is small, and the strength is decreased in useThe raw materials for the manufacture of silica brick. The higher the SiO2 content of silica raw material, the higher the refractoriness. The most harmful impurities are Al2O3, K2O, Na2O and so on. They seriously reduce the refractoriness of refractory products. Brick with SiO2 content of not less than 96% of silica as raw materials, adding mineralizer (e.g. millscale, lime) and binder (such as molasses, sulfite pulp waste liquid), after mixing, molding, drying, sintering and other processes in the system.

Q:Physical solid waste disposal: Too much addition will reduce the refractory and mechanical strength, increase porosity, so the amount of waste brick should not be too much.

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.
