This paper presents the results of the work carried out by the Department for Metal Working Processes at NUST for production technology of: high-strength automotive flat stock from bi-phase ferrite martensite steels (BPHFMS) on a broad-strip hot-rolling mill by staged laminar cooling on a runoff table, as well as K52–56 strength grade cold- and corrosion-resistant tubular strip bar. The metal’s ferrite grains rolled on the broad-strip mill are ground by combining the controlled rolling (CR) of strips with their rapid cooling (RCL). Thermal kinetic diagrams (TKDs) were created to show modeling sheet cooling, as well as to predict the resulting structure type depending on the metal cooling rate.

NUST MISiS热轧带钢生产技术的改进与发展

本文介绍了 NUST 金属加工工艺部为生产技术开展的工作结果: 在宽带热轧机上用双相铁素体马氏体钢 (BPHFMS) 生产高强度汽车扁平材径流台上的分级层流冷却,以及 K52-56 强度等级的耐冷和耐腐蚀管状带钢。通过将带钢的控制轧制 (CR) 与其快速冷却 (RCL) 相结合,在宽带轧机上轧制的金属铁素体晶粒被研磨。创建热动力学图 (TKD) 以显示建模板冷却,以及根据金属冷却速率预测所得结构类型。
