Product Description

hot sale skid rail chromium corundum brick for reheating furnace

The main mineral composition of hot sale skid rail chromium corundum brick is prun-Al2o3-cr2o3 solid solution.The secondary mineral composition is a small amount of composite spinel (or non-composite spinel), and the content of chromium oxide is 1% ~ 30% of firebrick. And in near day, high pure chrome corundum brick also make to fulfill the needs of special industries. High chromium bricks (Cr2O3≥90%) are mainly used in key parts of kilns such as coal chemical industry, chemical industry kilns, alkali-free glass fiber kilns, garbage incinerators, etc.There are two types of fused cast chrome corundum brick and sintered chrome corundum brick.

Chrome corundum brick in general refers to sintered chrome corundum brick.
α-Al2O3 was taken as the raw material, and a moderate amount of chromic oxide powder and fine powder of chrome corundum clinker were added.The content of chromic oxide in sintered chrome brick is generally lower than that of fused cast chrome corundum brick.

Moreover, the gray-pouring method can be used to prepare the gray-Al2o3 powder and chromium-oxide powder, and the grain-Al2o3 powder can be mixed uniformly, and the grout can be made by adding degumming agent and organic binder, and some chrome-corundum clinker can be added at the same time.It can be used as lining of glass kiln, screwing glass liquid flow hole cover plate brick, as backing lining of iron water pretreatment device, waste incinerator, coal water slurry pressurized gasifier,
