前言用电弧炉熔炼铸钢时,从化学成份对铸钢韧性所带来的结果分析,认为钢中的含硫量对钢具有很大的影响。硫对铸钢的影响在很多文献中有过报导,从同一材料的很多试样的纯渡测定结果得知,存在能引起塑性变形的夹杂物就会使铸钢的韧性恶化,这主要是硫化物的夹杂物存在的结果。 Preface The use of electric arc furnace smelting cast steel, from the chemical composition of the results of the toughness of the cast steel, that the sulfur content in steel has a great impact. The effect of sulfur on cast steel has been reported in many literatures. According to the results of pure ferro-gravimetric analysis of many samples of the same material, the presence of inclusions that can cause plastic deformation will deteriorate the toughness of the cast steel, mainly due to vulcanization Inclusion of the existence of the results.
