为了计算三炼钢氧气顶吹转炉的废钢比,从理论上推导了计算最大废钢用量公式。根据现在三炼钢转炉的操作和原料条件,计算表明转炉废钢比可以达到13.6～14.9％,与目前实际情况相比,还有约2％的潜力可挖。文中着重分析和讨论了影响废钢比的因素及目前废钢比低的原因,并提出了立足挖潜及创造条件进一步提高废钢比的途径和应采取的措施。
In order to calculate the scrap ratio of the three steelmaking oxygen top blown converter, the formula for calculating the maximum scrap steel was theoretically derived. According to the operation and raw material conditions of the three steelmaking converters, the calculation shows that the converter scrap ratio can reach 13.6-14.9%. Compared with the actual situation, about 2% of the potential can be tapped. The article analyzes and discusses the factors affecting the scrap ratio and the reasons for the current low scrap ratio. It also puts forward the approaches and the measures to be taken to tap the potential and create conditions to further improve the scrap ratio.
