铸石是一种经过生产加工而成的硅酸盐结晶材料,采用天然岩石(玄武岩、辉绿岩等基性岩)或某些工业废渣为主要原料,经融化、浇注、结晶、退火等工序制成。铸石具有优异的耐磨损、耐腐蚀性能。铸石制品主要有铸石板、铸石管、铸石复合管、夹套铸石管、铸石耐磨伸缩节、铸石耐磨阀门、铸石粉及以铸石粉为原料的各种耐磨耐腐胶泥等。已被广泛应用在电力、矿山、煤炭、冶金、化工、建筑等工业部门严重磨损腐蚀的部位和设备中。铸石是现代工业发展中比较重要的非金属工业新材料。
Cast basalt is a kind of silicate crystalline material after producing and processing, it made of natural rock (basalt, diabase and other basite) or some industrial waste as the main raw materials, by melting, casting, crystallization, annealing and other processes. Cast basalt have an excellent performance of high abrasive and high corrosion resistance. Cast basalt products mainly include cast basalt tile, cast basalt pipe, cast basalt lined steel pipe, clamp cast basalt pipe, cast basalt wear-resistant slip joints, cast basalt wear-resistant valves, cast basalt powder and various wear-resistant corrosion-resistant cement which use cast basalt powder as raw material. Cast basalt products have been widely used in industrial sectors which have serious wear and corrosion of parts and equipment, such as electric power, mining, metallurgy, coal, chemicals, construction and so on. Cast basalt is an indispensable non-metallic industrial new material in the development of modern industry.
