原载1984年№2 在利别茨克铸造中心厂,铸件在ДΚ-10抛丸室用ДЧЛ-2.5铁丸进行清理。抛丸机叶片磨损很快,每连续工作30~40h就得更换。全苏铸造工艺设备设计院利别茨克分院和该中心厂为了提高抛丸机叶片的耐磨性,共同研究出一种高铬铸铁。这种铸铁不含Ni、Cu、Mo和Ti这样的贵重和稀有合金元素,而叶片的使用寿命可提高3~4倍。炉料在容量为50kg的ЛП3—67—2型高频感应坩埚炉中熔炼。炉料的基本化学成分是:2.8~3.3%C;0.4~0.8%Si;0.4~
Originally set № 2 № 2 In the center of Libyk casting factory, the castings were cleaned with ДЧЛ-2.5 pellets in the Д-10 blast chamber. Blasting machine blades wear quickly, each continuous work 30 ~ 40h have to be replaced. All Su Foundry Equipment Design Institute Libeck branch and the center plant in order to improve the abrasion resistance of the shot blasting machine, jointly developed a high-chromium cast iron. This cast iron does not contain precious and rare alloying elements such as Ni, Cu, Mo and Ti, while the lifespan of the blades can be increased by 3 to 4 times. The charge is melted in a ЛП3-67-2 high-frequency induction crucible furnace with a capacity of 50 kg. The basic chemical composition of the charge is: 2.8 ~ 3.3% C; 0.4 ~ 0.8% Si; 0.4 ~
