我厂拥有65m~3和27m~3两座高炉,根据工厂发展的需要,即炼钢工程和电站发电扩建工程相继上马,2号高炉(27m~3)已满足不了以上的生产需求;加之其炉容小、设备陈旧、生产指标低,在全国小高炉行列中已经逐渐被淘汰,在工厂不断扩大再生产、进行资本投入的新形势下,经工厂研究、讨论及总公司调查、核实、结合1号高炉(65m~3)八年来的生产实践,就哈尔滨铁厂具体经济实力,对2号高炉进行科学、合理的扩容改造。 1 高炉主体改造设计 (1)由于炼钢上马6t转炉,电站发电所需煤气量的加大,结合上述原因,经过具体核
Our factory owns two blast furnaces of 65m ~ 3m and 27m ~ 3. According to the needs of the factory development, the steelmaking project and power generation expansion project have been launched. The No. 2 blast furnace (27m ~ 3) can not meet the above production needs. Small furnace capacity, outdated equipment, low production indicators, the country has gradually been eliminated in the ranks of small blast furnace, the plant continues to expand reproduction, capital investment in the new situation, the factory research, discussions and head office investigation, verification, combined with 1 No. Blast Furnace (65m ~ 3) eight years of production practice, Harbin Iron and Steel Company specific economic strength, the No. 2 blast furnace for scientific and rational expansion of the transformation. 1 Blast Furnace Redesign (1) Due to the 6t converter steelmaking, the amount of gas required for power generation increases, combined with the above reasons, after a specific nuclear
