铸石是一种经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﹑以及页岩）或工业废渣（高炉矿渣﹑钢渣﹑铜渣﹑铬渣﹑铁合金渣等）为主要原料﹐经配料、熔融、浇注、热处理等工序制成的晶体排列规整、质地坚硬、细腻的非金属工业材料。
Cast stone is a kind of silicate crystalline material made by processing. It is made of natural rock (basalt, diabase and other basic rocks, as well as shale) or industrial waste slag (blast furnace slag, steel slag, copper slag, chromium slag, ferroalloy slag, etc.) as the main raw material, through batching, melting, pouring, heat treatment and other processes. A non-metallic industrial material with high hardness and fine texture.
铸石具有很好的耐腐蚀、耐磨性能，其耐酸碱性可达99％以上，耐磨性比锰钢高5～10倍，比碳素钢高数十倍；其莫氏硬度7～8，仅次于金刚石和刚玉。但其韧性、抗冲击性较差，切削加工困难。
Cast stone has good corrosion resistance and wear resistance, its acid and alkali resistance can reach 99%, wear resistance is 5-10 times higher than manganese steel, higher than carbon steel dozens of times; its Mohr hardness is 7-8, second only to diamond and corundum. But its toughness and impact resistance are poor, and cutting process is difficult.
铸石制品主要有铸石管、铸石复合管、铸石板和铸石料，已被广泛应用在电力、煤炭、矿山、冶金、化工、建筑等工业部门的严重磨损、腐蚀部位，如刮板输送机底衬、溜槽里衬、风机壳内衬、磨机进出料装置等部位。可延长部件或设备的使用寿命为其它材料的十几倍乃至几十倍。
Cast stone products are mainly cast stone pipe, cast stone composite pipe, cast stone slab and cast stone, has been widely used in power, coal, mining, metallurgy, chemical industry, construction and other industrial sectors of serious wear and corrosion parts, such as scraper conveyor bottom lining, chute lining, fan shell lining, mill feeding and discharging devices and other parts. The service life of components or equipment can be extended to ten times or even tens of times of other materials.
在建筑上可用作仓库地坪， 和公共建筑的过道、楼梯踏步，成本低廉以及特别优异的耐磨、抗腐蚀等性能。厂房的耐酸地坪和墙裙，以及水工工程的大坝贴面和排砂孔衬里等。浅色或彩色铸石可以代替大理石、花岗石作内外装饰材料和地面材料。
It can be used in warehouse floor, corridor and staircase of public buildings. It has low cost and excellent wear and corrosion resistance. The acid floor and the skirt of the workshop, the dam face and the lining of the sand drain hole for the hydraulic engineering. Light colored or coloured cast stones can replace marble and granite as interior and exterior decorative materials and ground materials.
由于铸石制品的韧性较差，硬度较高，难以切削加工，一般按一定形状和尺寸加工制品。其固定方式采用砌筑和镶嵌的方法。
Because of the poor toughness and high hardness of cast stone products, it is difficult to cut them, so they are generally processed according to certain shapes and sizes. Its fixed way is masonry and mosaic.
