【摘要】 中厚板在轧制过程中产生金属流动变化，会引起中厚板边部和端部的不规则变形，从而导致成品的剪切损失。通过平面形状控制技术可以改善轧制后的中厚板平面形状，降低剪切损失量。基于平面形状控制技术基本原理，采用DEFORM有限元模拟软件建立中厚板轧制过程的三维模型，研究平面形状控制参数对轧件轧制后平面形状的影响规律。对中板轧机实施液压系统改造，并投入平面形状控制系统，将优化的平面形状控制参数应用于现场，综合成材率较投入前提高0.3%以上。更多还原

【Abstract】 During the plate rolling, the changes in metal flow can lead to irregular deformation at the edges and ends of the plate, ultimately resulting in shear loss in the finished product.By utilizing the plan view pattern control technology, it is possible to improve the pattern of the rolled plate and minimize shear losses.Based on the fundamental principles of plan view pattern control technology, the article sets up a 3D model of the plate rolling process with DEFORM finite element simulation software, studies the effects of the plan view pattern control parameters on the pattern of the rolled piece.Furthermore, the hydraulic system of the plate rolling mill is revamped, and a plan view pattern control system is put into operation.By applying the optimized plan view pattern control parameters on site, the comprehensive yield rate is increased by over 0.3% compared to that before the application of the plan view pattern control system.更多还原
