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: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

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:Semisilica brick, clay brick, high alumina brick and what is the difference?

The share of A12O3 and SiO2 is different

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 hot blast stove when the temperature did not rise against the brick interface decreased

How to keep the brick masonry temperature not lower than 600 DEG C, while the exhaust temperature is not higher than 400 DEG C.

Q:Common bond brick?

Manufacturing for silica brick binder hi-li sulfate pulp waste liquid and lime milk. When lime milk is used as a bond, it acts as a plasticizer. To increase the strength of lime brick in the drying process, as mineralizer in the firing, promote the transformation of quartz.

Q:The brick is mainly used in the place?

Also used for high temperature bearing part of hot blast stove and acid open hearth furnace.

Q:What role does silica play in refractories?

Low fractory refers to the alumina content between 10%~30%, SiO2 content is less than 85%, semisilica brick SiO2 = 65%,The SiO2 content of not less than 93%, refractory material to natural quartz rock as the main raw materials are called silica, silica brick, silica brick, quartz glass and special products. China's literature generally put this type of product is called "siliceous refractory products", which is the most important brick.
