The damage process of magnesia carbon brick
The damage process of magnesia carbon brick : the damage of magnesia carbon brick is firstly due to the oxidation of carbon in the brick to form a decarburized layer, plus the difference in thermal expansion rate between magnesium oxide and graphite at high temperatures (1.4% and 0.% at 1000 ℃, respectively) ), Leading to loose structure, reduced strength, and then eroded by slag, mechanical erosion, etc., the magnesium oxide particles in the brick are gradually eroded, falling off layer by layer, causing damage to the magnesium carbon brick. The damage process of magnesia carbon brick is: oxidation → decarburization → looseness → erosion → erosion → shedding → damage. The damage of the magnesia carbon brick is firstly the oxidation of the carbon in the hot surface of the working lining to form a thin decarburized layer. The oxidation of the carbon is due to the continuous oxidation of iron oxides in the slag and O? in the air and oxides such as CO?, SiO...
