铸石行业发展概述 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，加入一定的附加剂如角目岩、白云岩、萤石等、结晶剂如铬铁矿、钛镁矿等，经配料、熔化、浇注、结晶、退火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。 铸石具有资源丰富，生产工艺简单，成本低廉以及特别优异的耐磨、抗腐蚀等性能。铸石的主要用途是在工业上用作防腐蚀、耐磨材料，如酸、碱储罐、反应罐、酸洗池（槽）的防腐蚀衬里，各种矿石、灰渣、尾矿的溜槽和输送管道以及球磨的耐磨衬板等。

An overview of the development of stone industry cast stone is a kind of processed silicate crystalline materials, the use of natural rock (Xuan Wuyan, diabase and shale rocks) or industrial wastes (blast furnace slag, steel slag, copper slag, chromium slag, iron alloy slag etc.) as the main raw material, adding additives such as rocks, a certain angle. Dolomite, fluorite, crystallization agent such as chromium iron, titanium and magnesium ore, mixing, melting, pouring, crystallization and annealing process made of crystal non-metallic industrial materials, hard texture, delicate. Stone is rich in resources, simple production process, low cost and excellent abrasion resistance, corrosion resistance and other properties. The main purpose of stone is used as anti-corrosion, wear-resistant materials in industry, such as acid, alkali reaction tank, pickling tank (tank) anti-corrosion lining, all kinds of ores, tailings, slag chute and pipeline and milling wear-resisting lining board etc..

铸石制品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。 在建筑上可用作仓库地坪、公共建筑的过道、楼梯踏步，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，具有成本低廉、耐磨、抗腐蚀等性能。浅色或彩色铸石可以代替大理石、花岗石作为内外装饰材料和地面材料。

Stone products have been widely used in corrosion electricity, coal mining, metallurgy, chemical industry, construction and other industrial sectors such as severe wear, scraper conveyor chute bottom lining, lining, fan shell lining, mill feeding device and other parts, can prolong the service life of the parts or equipment for ten times or even dozens of other materials times. Can be used as a warehouse floor, in the construction of public buildings of the corridor, staircase, floor, dado and acid plant dam veneer hydraulic engineering and sand hole lining, has the advantages of low cost, abrasion resistance, corrosion resistance and other properties. Light color or color stone can replace marble and granite as the internal and external decoration materials and floor materials.

铸石材料在建材设备中主要代替不受冲击的金属材料耐磨件用在设备上，如皮带运输 机托辊，螺旋运输机内腔，搅拌机内表面，风选锤式粉碎机风管内壁,气力输送管道内衬等。

Stone materials in the building equipment mainly affected by the impact of the metal material instead of wear-resistant parts used in equipment, such as belt conveyor roller, screw conveyor is the mixer surface, winnowing hammer mill wind pipe, pneumatic conveying pipe lining, etc..
