CO partial pressure(A decrease in the CO partial pressure at low carbon contents will be greater in OBM than in BOF practice. 在含碳量较低的情况下， OBM 炼钢法 CO 分压的下降幅度大于 BOF 炼钢法。)
split shell(Most modem electric arc furnaces are of the split shell variety, and this means that the upper portion of the furnace shell can be quickly decoupled and removed from the bottom. 大部分现代电弧炉采用分体式炉壳。这就意味着上部炉壳可以快速拆卸，与炉底分离。)
