Corundum mullite refractory castables has high compressive strength, good high temperature volume stability and thermal shock stability, excellent wear resistance and corrosion resistance. Often used in large power plant boiler anti – wear lining and other high – temperature furnace lining.
The corundum mullite castable is often used in the front and back of large cement kilns, coal injection pipes and other parts of the lining of industrial kilns. Corundum mullite refractory castables is made of dense corundum and mullite as aggregate, white corundum powder, Al2o3 micro powder and mullite powder as fine powder. We are is production and manufacturing of refractory castable, export more than 60 countries and regions in the world, for example, America, Britain, India, Thailand, Vietnam, South Africa, myanmar, Germany and other countries and regions.
This series of refractory castable has the common advantages of corundum castable and mullite castable. With high temperature strength, thermal shock resistance and good performance of structure peeling. It also has good thermal shock resistance, high softening temperature under load, low creep rate under high temperature and good chemical corrosion resistance. It can be used in the lining of large power plant boiler and other high temperature kilns.
Corundum mullite refractory castables can adjust the content of Al2O3 and SiO2 in the matrix, so that it can generate mullite at high temperature and generate volume expansion, so as to improve thermal shock resistance and high-temperature strength.
It should be noted that corundum has high melting point, stable chemical properties, high temperature strength and other characteristics. So choose less than 0.088mm powder to add less than 15% is appropriate.
