sell high alumina corundum

タイトルまたは説明

refractory material, abrasive material, castable material, alumina, ceremic material, corundum. As one of our main products, using high-quality bauxite as starting material, high alumina corundum is mainly used for making abrasive material, abrasive tools and high performance refractory such as casting refractory, ramming materials, slid nozzle, and corundum products. it has got second prize of scientific and technological progress of ***6 that State Science and Technology Commission issued. Using high quality bauxite as main raw materials, through breaking and sieving, it is smelt in the more than ***0 degree Celsius electric arc furnace. The main composition Al2O3 is greater than *8%, Ti2O is smaller than 0.*3. After calcinations and acid treatment to sub-white corundum, its residual carbon content and impurity are reduced, so that products do not chalk and burst in application. According to the residual carbon content, they are divided into three varieties. Sub-white features hardness of white corundum, the toughness of brown corundum, it is mainly used in the manufacture of abrasives, abrasive and high-quality refractory instead of white corundum and dense corundum. its high quality and reliable performance made it to be the raw material of ideal advanced refractory at present. rita zhang tel: *****************0 fax: *****************8 cell: ***************6
