本文总结了辽阳粒铁(1-13次)试验的经验,指出了回转炉粒铁法的优点和冶炼特点。对原料准备、配料,温度控制,界山位置,炉内气氛和炉渣碱度等从理论和实践的结合上,进行了分析,提出了明确的冶炼条件。对包渣铁、结圈及炉衬寿命等技术关键问题进行了探讨。同时也指出了延长结圈周期,提高炉衬寿命和金属回收率的方向。
This paper summarizes the experience of Liaoyang Iron and Steel (1-13 times) experiment, points out the advantages and smelting characteristics of rotary iron ore. On the raw material preparation, ingredients, temperature control, boundary location, furnace atmosphere and basicity of slag from the combination of theory and practice, carried out an analysis, put forward a clear smelting conditions. Iron and steel package circle, knot circle and lining life and other key technical issues were discussed. At the same time, it also points out the direction of prolonging the knot cycle and increasing the lining life and metal recovery rate.
