| Abstract: | In order to improve the properties of some steel casting,the study was carried out based on the steel castings of ZG25MnNi and ZG30Mn2,which were practically used in coal mining industry.The button ingots of cast steel were produced by using of the vacuum arc furnace in lab.At the same time,the heat treatments were studied in theory and practice.As a result,a new kind of steel casting material was obtained,with a composition range of 0.2%-0.4% C,1%-1.8% Mn and 0.01%-0.04% Nb.The modified material has higher... |
