Product Description

Description of Corundum Brick Corundum bricks are refractory products with corundum as the main crystal phase, in which the Al2O3 content is greater than 90%. High normal temperature compressive strength (up to 340MPa). High load softening start temperature (greater than 1700°C). Good chemical stability, strong resistance to acidic or alkaline slag, metal and glass liquid. The thermal shock stability is related to its structure, the corrosion resistance of dense products is good, but the thermal shock stability is poor. There are two types of sintered corundum bricks and fused corundum bricks. Corundum bricks mainly used in iron-making blast furnaces and blast furnace hot blast stoves, refining furnaces outside steel-making furnaces, sliding water heaters, glass melting furnaces and petrochemical industrial furnaces, etc.

Product Features

Features of Corundum Brick High HardnessCorundum brick has a very high hardness, the hardness of corundum brick is close to Mohs hardness 9, which is harder than steel. Corrosion Resistance Corundum bricks have high corrosion resistance to various acids, alkalis and chemical solutions, and can work stably in harsh chemical environments. High Temperature Resistance The load softening degree of corundum bricks is generally between 1600-1800 degrees, and its refractory temperature can reach between 1770-2000 degrees. Dimensional Stability Corundum bricks have good thermal shock resistance, and the refractoriness is not lower than 1690 degrees. Its linear expansion coefficient between 20-450 degrees is about 0.03mm/degree, so it can withstand high temperature melt flow static pressure without rupture.
