由新疆建材陶瓷厂生产的高铝质电炉顶砖和磷酸盐高铝砖,于1990年10月20日在乌鲁木齐市通过了区级鉴定。高铝质电炉顶砖是以特级高铝熟料为原料,亚硫酸纸浆为结合剂,经粉碎、高压成型后采用高温烧成;磷酸盐砖是以磷酸溶液为结合剂,用锻烧高铝钒土作为骨料,经机压、热处理而成。该两种产品均可广泛用于冶金、建材、化工、动力、机械等部门。
The high-alumina electric furnace roof bricks and phosphate high-alumina bricks produced by Xinjiang Building Materials Ceramics Factory passed the district-level appraisal in Urumqi on October 20, 1990. The high-alumina electric furnace top brick is made of special grade high-alumina clinker, and sulfite paper pulp is used as a binding agent. After pulverization and high-pressure forming, it is fired at high temperature. The phosphate brick is a phosphoric acid solution used as a binder and calcined high aluminum. Vanadium earth is used as aggregate, and it is made by machine pressure and heat treatment. Both products can be widely used in metallurgy, building materials, chemicals, power, machinery and other departments.
