前言 随着工业的发展,对钢材的质量要求愈来愈高,要求钢中的氧、硫及非金属夹杂物含量要低,钢中夹杂物呈球状地分散分布,使钢材的机械性能达到各向同性。为了满足这些要求,曾采用过多种脱氧、脱硫及控制夹杂物的冶炼工艺。如电炉合成渣洗法、钢包底部吹氩搅拌法等,可使钢中氧、硫、夹杂物含量减少并使夹杂物在一定程度上变态 Preface With the development of industry, the quality of steel is getting higher and higher requirements of the steel oxygen, sulfur and non-metallic inclusions content is low, the steel inclusions were spherical dispersion, so that the mechanical properties of steel to each To the same sex. In order to meet these requirements, a variety of deoxidation, desulfurization and control of inclusions smelting process has been used. Such as electric furnace slag synthesis method, the ladle argon blowing at the bottom of the law, the steel can reduce oxygen, sulfur, inclusions and inclusions to a certain degree of metamorphosis
