摘要
本文提出了一种在液体金属中喷入粉剂的新方法及其相应的设备,并于高炉铁水运转包内进行了炉外脱硫处理等实践,得到了满意的结果,这一方法可简称为侧吹法。这种方法还用于冲天炉铁液处理,铁液在冲天炉前炉内吹镁粉处理后,浇铸成具有“三区结构”的钢锭模,其寿命比原来的灰铁钢锭模提高两倍,这一新工艺与现有的液态金属加粉剂的二次处理方法相比,具有一系列优点:粉剂利用率高,处理成本低;处理后的金属质量高;适用于各种粉剂的添加和多种液体合金的二次处理;设备制造、维修成本适中,易于实现自动化。
This paper describes a new method of introducing powdered reagents into molten-metal and it's apparatus, which were successfully used for carrying out desulphurization of blast-furnace liquid iron in hot - metal transfer ladles . It is called side - blown method . The method shows a number of advantages over other existing methods for the desulphurization of blast-furnace cast irons. The method can also be used for the treatment of liquid iron in a cupola forehearth for obtaining high quali-tymagnesium cast irons. A' three-zone 'structure of steel ingot molds was produced from the magnesium cast iron. The service life of the molds is as twice as the molds made of grey irons.
