Fused cast magmalox block, also named fused cast wear-resistance block, fused cast skid rail block, and fused cast zirconia mullite block. ZS Refractoriesâ?? fused cast magmalox block uses high quality bauxite, zircon sand and other raw materials, melting in an electric arc furnace at a high temperature ranging from 2000-2500�°C. The molten product then casted in molds, and kept to anneal for almost two weeks. It has advantages of compact structure, wear-resistance, impact resistance, strong thermal shock resistance, good corrosion resistance, slag resistance, and long service life. Being applicable in the areas of metallurgical pusher type reheating furnace, steel outlet tank, the lining of refuse incinerator, our fused cast magmalox block is also served as the key part of glass melting furnace.
Fused cast alumina block is also called fused cast block. As a kind of very important assisting refractories used in glass furnaces, it is composed of Alumina, Alumina and small amount of glass phase. It has superior corrosion resistance at the temperature up to 1350 C, zero bubble rate and pollution free to molten glass. It is also an ideal material for sidewall, paver of cooling zone/working end and the float canals of high quality glass furnaces. It is produced by melting and casting high purity alumina in electric furnace at 2000 corundum product is formed when alpha alumina and beta alumina inter-combine during their crystallization stage. In contact with molten glass, alpha beta alumina barely produces any blistering or stones. Therefore, alpha beta alumina blocks may be widely used in glass contact end zones of furnaces when glass quality is the priority. According to alumina content difference, fused cast alumina block can be categorized to fused cast (alpha) alumina block, fused cast (beta) alumina block, and fused cast block. We have casting method WS (VF) only.
