一、2012年全国投产炼钢转炉情况2012年1月份到12月底,全国投产炼钢转炉共38座,其中有6座为技术改造扩容建设的转炉,技术改造转炉的总公称吨位,由改造前的500吨增加为745吨,增加了245吨;其余32座为新建投产的转炉,新投产转炉的总公称吨位为3985吨,平均每座公称吨位125吨。6座改造转炉增加公称吨位和32座新建转炉总公称吨位之合为4230吨。按设计能力计算,新增加的粗钢产能约为4500万吨。
First, the country put into operation in 2012 steel converter situation From January 2012 to the end of December, the country put into operation a total of 38 steel converter, of which six for the technical transformation and expansion of the converter, the total tonnage of technical transformation converter, from before the transformation Of the 500 tons increased 745 tons, an increase of 245 tons; the remaining 32 for the new production of converters, the new commissioning of the converter’s total tonnage of 3985 tons, with an average of 125 tons per nominal tonnage. 6 modified converter to increase the nominal tonnage and 32 new converter total tonnage of 4230 tons. Calculated according to design capacity, the newly added crude steel production capacity is about 45 million tons.
