一、序言生产技术的发展,对钢材的使用性能提出越来越高的要求。平炉生产的镇静钢含硫量偏高,就鞍钢而言,由于受原料和工艺条件的限制,目前平炉成品钢的硫含量平均为0.025%,这样,残存于钢中的硫化物夹杂(主要是MnS)以及脱氧形成的氧化物夹杂(主要是Al_2O_3、SiO_2)已成为影响提高钢的内在质量的主要因素。为了提高钢质,鞍钢第二
First, the preamble production technology, the use of steel performance put forward higher and higher requirements. The flat steel produced by open hearth has high sulfur content. As far as Anshan Iron and Steel is concerned, due to the limitations of raw materials and process conditions, the average sulfur content of finished flat steel products is 0.025% on average. In this way, sulfide inclusions (mainly MnS) and oxide inclusions (mainly Al 2 O 3, SiO 2) formed by deoxidation have become the main factors affecting the intrinsic quality of steel. In order to improve the steel, Anshan Iron and Steel second
