摘要: 

本文结合生产研究了鞍钢碱性平爐冶炼重轨和无缝等碳素镇静钢的锰制度.研究结果指出:就上述鋼种而言,熔炼过程中的锰制度对钢中氧、硫含量以及轧制的成品質量並没有实际影响,换句话说,并没有必要规定熔池含锰量高於一定水平(>0.15—0.2%Mn).相反地,熔池含锰较高或在熔炼过程中加入锰铁均使降碳速度趋於缓慢,从而延长了熔炼时间.因此,只要高炉铁水中含硫量能够合乎规定,用低锰生铁作原料对炼钢並无害处.通过高爐生产数据分析,说明在鞍钢的操作条件下完全有可能生产含锰低而含硫合乎上述规定的铁水,应该认为用低锰生鉄冶炼重轨和无缝类型的优質鋼是切实可行的.

Abstract

Under the conditions of basic open hearth smelting at Anshan steel works which employ scrap-ore-liquid iron charge, a statistical analysis of the production data shows that within the limit investigated the manganese content of the molten bath has no appreciable influence upon the oxygen and sulphur content of the steel. Provided that the final chemical analysis of the steel was the same, no difference in mechanical properties was observed between the products derived from the higher (>0.2% Mn) and the lower(<0.1% Mn) manganese specifications during smelting. It is concluded that for the two steels (rail steel and a low-carbon steel for seamless tube) investigated at least, there is no necessity for adhering to the specification of manganese content above a certain level(>0.15-0.2% Mn) during smelting.On the contrary, with a view to maintaining a higher manganese-containing bath, it was usually found necessary to add iron-manganese or manganese ore at the end of melting down; in doing so, the rate of carbon-removal was to a certain extent retarded, thus lengthening the period of smelting and decreasing the rate of production.The use of low manganese-containing pig-iron for the smelting of certain qualitysteels is not only feasible but also advisable from the economic point of view, provided, of course, that the sulphur content of such pig-iron can be made low to meet the necessary requirement. A review of the iron production data in certain blast furnaces at Anshan shows that this is possible, although the best conditions for producing low manganese and low sulphur pig-iron in blast furnaces deserve further a more detailed investigation.
