随着社会发展用钢材质量的不断提高，优质铁矿石资源逐渐枯竭。与此同时，废钢的储量和回收量也在逐步增加，这将导致钢中残留锡含量的不断增加，严重制约了钢材质量的提高和废钢的循环利用。因此，在黑色金属冶炼过程中，有必要尽可能多地去除锡。然而，在传统的冶炼工艺中，钢中的锡不能被有效地去除。介绍了钢中残留锡的来源、存在形式和含量控制水平，以及目前黑色金属冶炼过程中的除锡工艺。
With the continuous improvement of the quality of steel for social development, high-quality iron ore resources have been gradually depleted. Meanwhile, the scrap steel reserve and recycling volume are gradually increasing, which will result in the continuous increase of the residual tin content in steel, which seriously restricts the improvement of steel quality and the circulation-utilization of scrap. Therefore, it is necessary to remove as much tin as possible in the ferrous metallurgy process. However, tin in steel cannot be effectively removed in the conventional smelting process. In this paper, the origination, the existing forms, and the content control levels of the residual tin in steel are presented, as well as the current processes of tin removal in the ferrous metallurgy process.
