Description

Dear sirs, We are located in the biggest production base of white fused alumina(WFA or WA)in China. WFA is a high grade refractory material, made from the top grade aluminium oxide powder melted at 2, **0 degrees Centigrade in the EAF and naturally cooling or water cooling. With the main crystallize phase of a-Al2O3, WFA melting in tilting furnace is of high bulk density and low porosity, thus the volume stability and thermal shock resistance can be well improved. WFA is the main starting material to produce high grade shaped and unshaped refractories widedly used in the field of iron and steel, cement, ceramics, petrochemical industry, ***** The WFA series shaped refractories include such as large corundum bricks, corundum and mullite-corundum sagger, refined porous plug bricks, composite nozzle and lining materials for all kinds of high-temperature industrial furnaces. The WFA series unshaped refractories include ladle castables, blast furnace trough castables, gunning materials, pre-cast blocks, ***** WFA is also used for consolidation
