      Introduction of dense corundum products

    Dense corundum is a high-purity refractory material made of high-purity alumina and reducing agent in a certain ratio in an electric arc furnace after high-temperature melting and cooling.

    The main crystal phase of dense corundum is more than 96%, which is A -Al2O3The porosity is less than 4%, the color is light gray, it has a high melting point, a very high volume density and a very low porosity, and has excellent wear resistance, slag resistance, volume stability and thermal shock resistance at high temperatures.The company's dense corundum can be made according to customer requirements of various sand and fine powder.

    Our compact corundum physical and chemical indicators are as follows:

      Product use

    The product is widely used in iron and steel metallurgy, petrochemical, building materials ceramics and other industries, mainly used as blast furnace iron ditch refractory ramming material, ladle castable, ramming material, prefabricated parts and other amorphous refractory materials, as well as continuous casting three large pieces, breathable brick, nozzle seat brick and other shaped products. Compared with other laying materials, dense corundum can be more resistant to high temperature, more resistant to erosion, the use of a longer time, can achieve the purpose of cost savings.
