用含碳1.5%的铸钢合金来铸造货车整体车轮第一机械工业部机车车辆研究所、工艺研究院、设计一分局等单位根据设计一分局苏联专家的建议,从去年6月开始收集资料,经过实验室熔炼和热处理试验在56年12月到57年3月同四方机车车辆制造厂合作进行了第一次整体车轮铸造的试验.这种新型的铸造合金在国外也是到近年才开始采用,它的耐磨性、耐磨性、耐“剥离”性以及抱闸时的耐热裂性都大大地超过了一
Casting 1.5% carbon steel cast iron truck as a whole wheel The first Ministry of Machinery Industry locomotive and rolling stock Institute, Technology Research Institute, Design Branch and other units according to the design of a branch of the Soviet Union experts advice from June last year to collect information, After the laboratory smelting and heat treatment test carried out the first overall wheel casting test in cooperation with Sifang Locomotive and Rolling Stock Works from December of 56 to March of 57. This new type of casting alloy was also adopted in recent years in foreign countries, Its abrasion resistance, abrasion resistance, resistance to “peel off” properties and resistance to hot cracking at the brake greatly exceed one
