1985年9月15日点火投产的宝钢1号高炉,有效容积为4063m~3,居全国高炉之冠。据统计,容积在4000m~8以上的巨型高炉,世界上仅24座。宝钢1号高炉炉缸直径13.4m,高110m,年产生铁300万吨,设有4个铁口,36个风口。全套设备主要从日本新日铁引进,其工艺装备和控制系统具有七十年代末世界先进水平,突出地表现为大(大型化)、新(技术新)、精(精密)、高(高效率)等四大特点。在高炉工艺上,采用了精料、高压(最高0.25MPa),高风温(最高1310℃),综合鼓风(富氧4%,脱湿至6～9g/m~3、基本保持恒温鼓风,)喷煤(100kg/t),可调炉喉控制布料,热数模预测生铁含硅量及多铁口操作等技术。
Baosteel No. 1 blast furnace put into operation on September 15, 1985 with an effective volume of 4063m ~ 3, ranking the highest in the national blast furnace. According to statistics, the volume of 4000m ~ 8 in the giant blast furnace, only 24 in the world. Baosteel No. 1 blast furnace hearth diameter of 13.4m, 110m high, with an annual output of 3 million tons of iron, with four iron mouth, 36 tuyeres. The complete set of equipment is mainly imported from Japan’s Nippon Steel. Its process equipment and control system have the world’s advanced level in the late seventies with outstanding performance in large (large scale), new (new technology, precision, high (high efficiency ) And other four major characteristics. In the blast furnace process, the use of fine materials, high pressure (up to 0.25MPa), high wind temperature (up to 1310 ℃), integrated blast (4% oxygen, dehumidification to 6 ~ 9g / Wind, coal injection (100kg / t), adjustable throat control of fabric, hot die to predict the amount of silicon in pig iron and multi-tipped operation.
