我院70公斤的土转炉,最初是由同学们倡议并动手把原来顶吹用氧转炉改装而成的,先后经过多次试验,均未能炼成钢。但在党的领导和支持下,同学们终于在多次失败的基础,用这个土转炉冶炼出高炭工具钢和矽钢。目前我们正在这个土转炉内进行有关土高炉生铁(低矽、高硫)炼钢的试验研究工作。一、试验中转炉设备的改进 (1)最初所采用的转炉的内型图及主要尺寸如图1所示: 所使用的鼓风机是:风压350公厘水柱,风量9立方公尺/分。鼓风
Our 70 kg soil converter was first proposed and practiced by our students. It was converted from an oxygen converter that was top-blown. It has been repeatedly tested and failed to produce steel. However, under the leadership and support of the party, the students finally used this earth smelter to smelt high-carbon tool steel and silicon steel on the basis of repeated failures. At present, we are carrying out experimental research on earth blast furnace pig iron (low-silicon, high-sulfur) steelmaking in this soil rotary kiln. First, the improvement of the converter equipment (1) The initial converter used in the main figure and the main dimensions shown in Figure 1: The blower used is: air pressure 350 mm water column, the air volume of 9 cubic meters / min.
