Beschreibung
Zusammenfassung:	The invention discloses a method for producing low-alloy peritectic steel by a conventional slab continuous casting machine. The method comprises the technological processes of decarburization converter smelting, LF refining and slab continuous casting. Through the adjustment on the continuous casting procedures of the conventional slab continuous casting machine, the phenomenon of large liquid level fluctuation during peritectic steel pouring is eliminated, the shock mark depth of a casting blank is obviously reduced, cracks and concave parts in the surface of the casting blank are eliminated, the conventional slab continuous casting machine can produce flawless low-alloy peritectic steel in batches, and high-quality raw materials are provided for low-alloy high-strength steel stable in production performance. 本发明公开了种常规板坯连铸机生产低合金包晶钢的方法，其工艺流程为：脱碳转炉冶炼LF炉精炼板坯连铸。本发明通过对常规板坯连铸机连铸流程的调整，消除了在浇注包晶钢时的液位波动大的现象，明显减轻了铸坯震痕深度，消除了铸坯表面的裂纹和凹陷，实现了常规板坯连铸机批量生产无缺陷的低合金包晶钢，为生产性能稳定的低合金高强钢提供优质原料。
