Neutral Refractory Structure
Neutral neutral refractory refractory structure with aluminum oxide, chromium oxide or carbon as the main ingredient. Corundum products containing alumina 95% above is a kind of high quality refractory materials use. Whose main ingredient is chromium oxide-chrome bricks for slag corrosion resistance, good, but less thermal shock resistance, high temperature load deformation temperature is low. Carbon refractory brick, graphite and SIC products, its low thermal expansion coefficient and high thermal conductivity, thermal shock performance, high temperature strength, resistance to acid, alkali and salt erosion, especially in weak acid and alkali has a better ability to resist, without wetting of the metal and slag, light. Widely used as high temperature and lining materials, also used in petroleum, chemical autoclave lining.
