利别茨克铸造中心厂的铸件在ДК－10抛丸室用дчл－2．5铁丸清理。而其抛丸机叶轮的全套叶片每连续工作30－40/小时就得更换。全苏铸造生产工艺设计院利别茨克分院和铸造中心厂为了提高抛丸机叶片的抗磨性,一起研究出了一种高铬铸铁,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2－3倍。在容量50公斤的лп3－67－2型高频感应坩埚炉中熔炼炉料。配料的基本化学成份是:2．8－3．3%C;0．4－0．8%Si;0．4－0．9%Mn; 17－24%Cr; 0．1－0．15%V。钒,φC75硅铁和MH75锰钦在基本炉料熔化之后加入炉中。熔炼在耐热坩埚中进行。
Castings at the Liberium Casting Center plant are cleaned with дчл-2.5 iron pellets in the ДК-10 blast chamber. And its full range of Blasting Blades leaves every 30-40 / hour work have to be replaced. All-Su Foundry Design Institute Libyck Branch and Foundry Center In order to improve the abrasion resistance of the Blasting Blades, a high chromium cast iron was developed that does not contain Ni, Cu, Mo and Ti Precious and rare alloying elements. The blade life can be increased 2-3 times. In 50 kg capacity of лп3-67-2 high-frequency induction crucible furnace melting charge. The basic chemical ingredients of the ingredients are: 2.8-3.3% C; 0.4-0.8% Si; 0.4-0.9% Mn; 17-24% Cr; 0.1-0.15 % V. Vanadium, φC75 Ferrosilicon, and MH75 Manganese are added to the furnace after the primary charge has melted. Melting in a heat-resistant crucible.
