一项所述的铁水的前一类型的精炼talgyu处理和塔林治疗通过使用作为，在横跨上的方式排除步骤的行的做法，释放出迅速炉渣中，根据足以汉阳排除过程中， 在成本和质量方面进行足够的架线处理。 铁水5从类型到talgyu处理过程talgyu通过供应气态氧源处理铁水精炼预期取喷枪（2），围绕至少在转炉型精炼talgyu处理步骤中产生的炉渣的一部分（1） 作为排除步骤和，排除后过程中，具有添加CaO系maeyongje和塔林处理所述残余物铁水通过供给从sangchwi喷枪气态氧源到转炉型精炼的塔林处理步骤的预处理方法，其从炉中排出， 测量talgyu处理期间在炉中熔渣的高度，并结束处理talgyu，而它在一个预定范围内的比率为炉干舷通过从入口到炉kkajiui铁水熔池表面的距离在炉渣卡诺的测得的高度来定义。

A single converter type refining talgyu processing and Tallinn treatment of the molten iron by using a, when carried in a row across a ruled step on the way, was discharged out quickly furnace a sufficient amount of slag in the excluded process, cost and a sufficient Tallinn process in terms of quality. At least a portion of talgyu treatment step to a molten iron 5 in a converter type refining (1) from sangchwi lance (2) supplying a gaseous oxygen source to talgyu process the molten iron and slag produced in talgyu treatment process in a converter type refining as excluded step and, after excluded process, a pre-processing method having the Tallinn processing step of adding the CaO-based maeyongje and Tallinn processing the residue was molten iron by supplying a gaseous oxygen source from sangchwi lance into a converter type refining to discharge from, talgyu measuring the height of the slag in the furnace during the process, and ends the processing talgyu while it is in a ratio within a predetermined range for the furnace freeboard is defined as the distance from the entrance of furnace to the molten iron bath surface measuring slag height in the furnace.
