鑄石Cast Basalt
鑄石是一種經(jīng)過生產(chǎn)加工而成的硅酸鹽結(jié)晶材料,采用天然巖石(玄武巖、輝綠巖等基性巖)或某些工業(yè)廢渣為主要原料,經(jīng)融化、澆注、結(jié)晶、退火等工序制成。鑄石具有優(yōu)異的耐磨損、耐腐蝕性能。鑄石制品主要有鑄石板、鑄石管、鑄石復(fù)合管、夾套鑄石管、鑄石耐磨伸縮節(jié)、鑄石耐磨閥門、鑄石粉及以鑄石粉為原料的各種耐磨耐腐膠泥等。已被廣泛應(yīng)用在電力、礦山、煤炭、冶金、化工、建筑等工業(yè)部門嚴(yán)重磨損腐蝕的部位和設(shè)備中。
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.
