Q: Is there a big difference between two high alumina brick and one high alumina brick?: According to my experience, two kinds of high alumina bricks from the index, there is a big difference between the content of AL2O3, a high aluminum brick in 75%, two grade high alumina bricks in 65%, so the content is not the same, also decided that the use of temperature difference, the difference is very big.

Q: Aluminum content 38, silicon content 55 What refractory bricks?: Hello Only on behalf of the Zhengzhou colt as refractory product index your answer to this question is not entirely separate from the chemical index of aluminum content, silicon content and judgment, personally think that three types of refractory bricks may respectively is: Two: semisilica brick high alumina brick

Q: Difference between low creep high alumina brick and ordinary high alumina brick: The question is good, these two belong to the high aluminum brick products, when many manufacturers buy, I do not know how to distinguish.

Q: What are the alloy wear resistance materials?: According to the composition of Beijing Naimo metal materials company will wear resistant metal materials is divided into the following five categories: one: high manganese steel series: high manganese steel (ZGMn13),

Q: Corundum, high alumina and fireclay refractory difference is what: They differ in that the alumina content is different, and the content is in order: corundum > high alumina > clay.

Q: How to test the aluminium bricks of high alumina refractory bricks?: Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard

Q: Does the chimney have high acid resistance?: If it is an ordinary high alumina brick, it does not meet the requirements of acid resistance, and only the chimney lined with acid resistant bricks.

Q: Use of high alumina refractory bricks?: High alumina brick refractory than clay refractory bricks and brick refractory degree are higher, up to 1750~1790 DEG C, which belongs to high-grade refractory materials.

Q: Which thermal shock stability of clay brick and high alumina brick is good?: Generally, the thermal shock resistance of high alumina brick products is worse than that of clay brick products

Q: What is the difference between metal compounds and metal solid solutions?: Solid solution refers to the alloy phase in which the solute atoms are dissolved into the solvent lattice and remain solvent type. A crystalline substance consisting usually of atoms or molecules in which a chemical substance is dissolved as a base; other substances are found in alloys and silicate systems; also present in polyatomic substances. The mixture can be treated as a solution when the crystal structure of the solvent can be stabilized and homogeneous after addition of solute. Some mixtures can form solid solutions in many concentrations, while some mixtures do not form solid solutions at all.
