中厚板控冷过程中存在集管冷却时钢板横向温度不均匀造成钢板变形的现象,采用边部遮蔽的方法能减小边部冷却不均匀性。分析了采用边部遮蔽后的钢板横向流量;并用有限元分析方法,模拟分析了不同厚度、宽度、集管流量下的温度场,确定最佳遮蔽量,开发了边部遮蔽数学模型,可以用于层流冷却系统边部遮蔽的计算机控制。 In the process of controlled cooling of plate, there is a phenomenon that the plate is deformed due to the non-uniform temperature of the transverse plate of the pipe when the header cools, and the method of edge shielding can reduce the non-uniformity of the edge cooling. The transverse flow rate of the steel plate after the edge masking was analyzed. The temperature field under different thickness, width and flow rate was simulated and analyzed by finite element method. The optimal masking amount was determined. The mathematical model of the edge masking was developed. Computer control of shadowing in the laminar cooling system.
