| 铸石用途 Use of cast stone 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。 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。 Cast stone products are mainly cast stone pipe, cast stone compound pipe, cast stone plate and cast stone. It has been widely used in the serious wear and corrosion parts of industrial sectors such as electric power, coal, mine, metallurgy, chemical industry, construction and other industrial sectors, such as the bottom lining of the scraper conveyor, the lining of the chute, the inner lining of the wind machine shell, the mill import and export equipment and so on. The service life of components or equipment can be extended to ten times or even tens of times of other materials. Because the toughness of cast stone products is poor, the hardness is relatively high, and it is difficult to cut. The method of masonry and inlay is adopted in the fixed way. 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。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。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。 The main use of cast stone is used as anti-corrosion and wear-resistant material in industry, such as acid, alkali storage tank, reaction tank, acid washing tank (trough) anticorrosion lining, all kinds of ore, ash, tailing chute and conveying pipe, and abrasion resistant lining of ball mill. It can be used as the floor of the warehouse, the passageway of the public buildings, the staircase, the acid resistant floor and the wall skirt of the factory, and the lining of the dam of the hydraulic engineering and the lining of the sand drain. Light colored or coloured cast stones can replace marble and granite as interior and exterior decorative materials and ground 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。 Cast stone material is mainly used in building materials equipment instead of impact metal wear-resistant parts. Such as belt conveyor roller, screw conveyor chamber, mixer inner surface, wind hammer crusher air pipe inner wall, pneumatic conveyor pipe lining, etc. 1、通用型铸石耐磨件 1. Universal cast stone wear-resistant parts 皮带输送机大小托辊辊套使用的铸石件均为通用型铸石。这种铸石件加工容易,截面均为圆环形，直接由挤出机中挤出并按长度要求切割成段，经过锻烧形成了产品。由于通用件生产容易，不需专门订货。所以这种产品用得较多。使用效果也令人满意,其优点是：一般使用寿命比普通金属套托辊长二倍以上。第二，由于重量轻，降低了维修劳动强度;第三，运行情况稳定、可靠、无噪音。第四,价格便宜,其造价仅为金属托辊的1/3。 The cast stone parts used for the belt roller of the belt conveyor are all general cast stones. This kind of stone castings is easy to be processed, and the cross-section is circular. It is extruded directly from the extruder and cut into segments according to the length requirement. As the general parts are easy to manufacture, no special orders are required. So this product is used more. The effect is satisfactory. The advantage is that the service life is two times longer than that of the ordinary metal supporting roller. Second, because the weight is light, the maintenance labor intensity is reduced; third, the operation is stable, reliable and no noise. Fourth, the price is cheap, and its cost is only 1/3 of the metal idler. 2、通用异型铸石及特异型耐磨件 2. Common special-shaped cast stone and specific wear resistant parts 风选锤式粉碎机风管,搅拌机、螺旋运输机,气力输送设备是使用通用异型铸石的设备。通用异型 Air hammer hammer mill, air mixer, mixer, screw conveyor and pneumatic conveying equipment are equipment used for general purpose special-shaped cast stone. General special-shaped 铸石使用效果和通用型铸石耐磨件相似,但生产相对复杂,价格也高于通用型铸石。搅拌机搅刀，挤砖机绞刀叶片，风机壳等是使用特异型铸石的设备。特殊型铸石生产更加复杂，全部都需作新模具。且生产量小，模具使用次数少。限制了使用厂家的应用。特异型铸石件受制造质量和安装质量的影响，使用寿命不稳定有些零件如搅刀叶片，搅拌机搅刀还要承受部分拉力，需要配制金属骨架，安装麻烦，使用性能也必然受到影响。 The effect of cast stone is similar to that of general cast stone wear resistant parts, but the production is relatively complex and the price is higher than that of general cast stone. Mixer mixer, cutter blade, fan housing and so on are special casting equipment. The production of special cast stones is more complex, all of which need new moulds. And the production quantity is small, the use of the die is less. The application of the manufacturer is limited. The specific type of cast stone is influenced by the quality of manufacture and the quality of installation. The service life is not stable, such as the blade of the agitator, and the agitator has to bear part of the pulling force. It is necessary to make up the metal skeleton, and the installation is troublesome, and the performance will inevitably be affected. |
