产品描述

　　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 -Al2O3, the porosity is less than 4%, the color is light gray, it has high melting point, high volume density and very low porosity. It has excellent wear resistance, slag resistance, volume stability and thermal shock resistance at high temperature.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:

Item	Al₂O₃	Fe₂O₃	SiO₂	T.C	Bulk density B .D
Index	≥ 98.5%	≤ 0.15%	≤ 0.6%	≤ 0.1%	≥ 3.88g/cm3

　　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.
