外购钢坯质量评价与应用

QUALITY EVALUATION ON PURCHASED STEEL BILLETS AND ITS APPLICATION

某钢厂通过外购钢坯,解决炼钢和轧钢生产能力不匹配问题,但在外购钢坯使用过程中经常会出现表面质量缺陷和内部质量缺陷。通过对外购钢坯的化学成分、力学性能、表面质量等情况来评价各厂家钢坯的质量,并与本厂自供坯进行质量指标对比,选择质量稳定的厂家供货,同时安排合适的产线、品种和规格进行轧制,保障外购钢坯在使用过程中质量能得到有效控制,为外购钢坯的采购起指导作用,减少在生产过程中产生次品,才能大幅度提高产品的质量和经济效益。

A steel plant has solved the problem of mismatched production capacity between steelmaking and rolling by purchasing purchased steel billets.However,surface and internal quality defects often occur during the use of purchased steel billets.By evaluating the quality of purchased steel billets from various manufacturers based on their chemical composition,mechanical properties,surface quality,and other factors,and comparing them with our own supplied billets,in order to ensure that the quality of purchased steel billets can be effectively controlled during use,manufacturers with stable quality are selected to supply billets,and suitable production lines,varieties and specifications for rolling are arranged.This can provide guidance for the procurement of purchasedsteel billets,reduce the production of defective products during the production process,and greatly improve product quality and economic efficiency.
