石墨铸型在抗磨铁碳合金生产中的应用

THE APPLICATION OF GRAPHITE MOLD IN PRODUCING WEAR RESISTANT IRON—CARBON ALLOYS

晶质石墨是一种优良的铸型材料。同砂型相比,石墨型铸件的外表光洁,尺寸精度高,内在组织晶粒细小,机械性能特别是硬度和冲击韧性有了一定程度的提高,石墨铸型具有生产实用性。

Crystal graphite is an excellent material for making casting molds, compared with the castings produced in sand molds, the castings produced in graphite molds have more smooth surfaces, more precise dimentions, finer crystal particles, higher mechanical properties, especially the higher hardness and toughness. Graphite mold is very practical in producing castings.
