General Information

Refractory Acid-resistant brick is the main refractory materials of steel processing system cold-rolled sheet,
silicon steel line, etc. used for acid reproduction baking furnace, and its performance will directly
affect the service life and economic benefits of acid reproduction baking furnace.

It is used as working lining for anti erosion and acid proof pickling groove,acid storage tank,leaching tower,anti-erosion and acid proof floor,tubes and etc, Except hydrofluoric acid as the medium in chemical, petroleum, metallurgic, smelt, electric power, fertilizer, fiber, pharmacy, and alkaline system industries.

Applications
The reaction boilers, columns & tanks.
Mixing pools
Acid-resistant walls in non-ferrous metal industry
Acid-resistant structures in chemical industry.

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: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 introduction of silica brick
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.
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:Can not use it two brick
The softening temperature is up to 1640~1670 DEG C, and the volume is stable at high temperature for a long time.
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: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: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:What is the main material of silica brick
More than 94% silica content. True density 2.35g/cm3. With acid resistance, slag erosion performance.
Q:Why will expand when heated brick
In the process of SiO2 drying, the four crystalline transformation points of 117, 163, 180~270 and 573 DEG C are found, among which the volume expansion caused by the 180~270 is the largest.
