Of iron slagging way: typically a high-lance operation. Slag FeO content in a long time has been relatively high, so lime dissolve faster, slag composition is generally not enter multiple domains, until late blowing in slag FeO amount was decreased, and finally reach the end component C. Advantages: slag activity is high, less unmelted lime calcium aluminosilicate Deoxidants price, lime consumption is low, blowing early, mid, go phosphorus, sulfur better. Disadvantages: slag bubble serious, prone to splash calcium aluminosilicate Deoxidants, while the more serious erosion of the lining slag. Refining: The First refining liquid steel degassing, deoxidation, desulfurization calcium aluminosilicate Deoxidants wholesale in a vacuum, inert or reducing atmosphere containers, removing inclusions and carry out fine-tuning components. Benefits will steelmaking two steps are: to improve the quality of steel, shorten the refining time, simplify the process and reduce production costs. Refining of many types can be divided into external atmospheric pressure outside the refining and vacuum refining categories. Different treatment methods, can be divided into outer outside the ladle refining process type and ladle refining furnace type.
