根据2300中板轧机的设备特点、轧制产品的工艺状况,开发了一个能适应轧件宽度变化范围较大的2300四辊轧机支撑辊辊型的计算机仿真程序,并研制了一种新的2300四辊轧机支撑辊辊型曲线,以提高该轧机的板形控制能力。研制的新支撑辊辊型曲线经过一年的工业化生产,取得明显的实效,钢板的横向同板差下降幅度达60%~75%;同时钢板的板形明显改善、薄板的边浪现象基本消除;另外轧制压力下降幅度达5%~7.5%,辊间压力分布变化趋缓、轧辊磨损减少、使用周期延长。 According to the equipment characteristics of 2300 medium plate mill and the technological conditions of the rolled products, a computer simulation program was developed to support the roller roll type of the 2300 four-high mill with a wide range of variation of the rolling width. A new 2300 The four-roll mill supports roll-type curves to improve the mill’s shape control. The new backup roll-shaped curve developed after one year of industrial production has achieved remarkable results. The transverse plate-like difference of steel plates has been reduced by 60% -75%. At the same time, the plate shape of the steel plate has been obviously improved, and the phenomenon of edge waves on the plate has been basically eliminated ; In addition, the rolling pressure drop rate of 5% to 7.5%, the pressure distribution between the rolls slowed down, reducing wear and tear, the use of extended periods.
