摘　　要：步进梁连续式加热炉水印会导致中厚板轧制钢板厚度的波动。针对厚板加热炉的结构形式和厚板轧机控制模型的设定特点,研究出了一种可以针对加热炉水印位置进行轧制设定的控制方法。使用此方法可以对加热炉水印位置的轧制力进行单独设定,从而减轻甚至消除加热炉水印对厚板厚度的影响。在宝钢5 m厚板轧机现场应用后,厚板厚度精度得到了明显改善。The skid of walking beam slab reheating furnace can cause fluctuation on the final plate thickness during plate rolling. Based on analysis on both the structure of walking beam slab reheating furnace and controlling method of plate mill,a controlling method based on setting up on the skid position of slab was established. By using this controlling method,the fluctuation of plate thickness caused by reheating slab skid can be alleviated. After the application of this method,the thickness accuracy of plate produced by Baosteel 5 m plate mill was improved.
