层冷控制模型在中宽带轧制中的应用

An Application of Laminar Cooling Model in Medium Hot Strip Mill Run Out Table

介绍了层冷过程控制模型及其冷却模式、冷却方式和模型自学习策略,将层流冷却控制模型应用于国内某厂中宽带轧后冷却过程.采用现场Q235A、4.5mm热轧中宽带生产数据,分析了带钢在输出辊道上集管组温降及现场应用效果,结果表明,该层流冷却控制模型现场应用效果良好.

The laminar cooling control model was used during run out table cooling process after rolling. The model and cooling mode, control mode and self adaptation of the model were introduced in detail. The bank temperature drop on ROT of Q235A,4.5mm steel in field was analyzed by the number. Data gathered in field show that the laminar cooling online model works well.
