摘要
SPHC钢作为一种低碳低硅热轧钢,因其优异的塑性和延展性,广泛应用于汽车、家电及建筑等领域。然而,随着下游市场需求饱和,对其力学性能的要求日益提高。在轧制及卷取工序中,SPHC钢易出现边损、边裂、起皮等缺陷,导致显著的经济损失。为优化生产工艺并减少缺陷,结合JMatPro材料性能模拟软件计算SPHC钢的关键参数,并应用Deform软件构建轧制过程仿真模型,系统分析其热轧变形行为。通过模拟与实验验证,确定了最优工艺参数:粗轧单道次压下率为20%、轧制温度为1150℃时,轧制力表现最佳。此外,通过温度场与等效应力场分析,揭示了变形机制与缺陷成因,为实际生产提供了可靠的数据支持。
The SPHC steel,as a low-carbon and low-silicon hot-rolled steel,has been extensively utilized in automotive components,household appliances,and architecture owing to its superior formability and cold-working adaptability.However,as the downstream markets have been becoming saturated,higher demands were placed on its mechanical properties.During rolling and coiling processes,defects such as edge cracks,peeling,and surface damage frequently occurred,which leaded to significant economic losses.In order to optimize manufacturing technique and minimize defects,we combined with material property simulation software JMatPro to calculate SPHC steel key parameters,and finished a rolling process simulation model in Deform,so as to systematically analyze the hot-rolling deformation behavior of SPHC steel.Through simulation and experimental validation,the optimal parameters were determined that a single-pass reduction rate of 20%and a rolling temperature of 1150℃yielded the best rolling force performance.Furthermore,the temperature and equivalent stress field analyses revealed that deformation mechanisms and defect origins,which provided the reliable data for actual productions.
