Aluminum magnesium carbon brick and manufacturing process thereof

2019-11-13
second

The alumina-magnesia-carbon brick refers to a refractory product made of super high alumina bauxite or corundum sand, magnesia sand and flaky graphite. Super high alumina bauxite or corundum sand, magnesia sand and flaky graphite are the main products for the lining of fire. It is characterized in that it has the advantages of high corrosion resistance and non-flaking due to carbon content at high temperature, and also has the advantage of exhibiting a high residual linear expansion ratio due to heat generation of spinel during use, thereby becoming a new development quality. Lined with bricks.

高纯镁砖用途


Using special high-alumina bauxite as raw material, because it contains a certain proportion of SiO2 and other impurities, and the structure is not dense, and the slag resistance is poor. To improve its slag resistance, some special high-grade aluminum bismuth can be replaced by electrofusion or sintered corundum. earth. In order to improve the oxidation resistance and high temperature strength of the product, a measure of adding a small amount of metal powder is adopted, but the thermal shock resistance is lowered, thereby increasing the content of flaky graphite.
