影响热轧轧辊原始辊型精度的因素分析

ANALYSIS ABOUT FACTORS TO AFFECT THE ORIGINAL ROLL PROFILE PRECISION OF HOT-ROLLING ROLL

保证轧辊的原始辊型是计算精确热态辊型的基础。以某钢厂2 250mm热轧宽带钢精轧机组轧辊原始辊型保持为研究背景,研究了轧辊下机温度、磨前强度、磨削热、磨后空冷温度对热轧轧辊原始辊型精度的影响。将研究成果应用到实际生产中后,磨削后的原始辊型精度得到保障。

To keep the original roll profile of roll is the base to calculate the hot roll precise profile. With keeping the original roll profile for the rolls of 2 250 mm hot-rolling wide strip steel finish rolling set of some plant as background,it is researched the influence of roll demount temperature,strength before grinding,grinding heat,air cooling temperature after grinding on the original roll profile precision of rolls in hot rolling. After the research achievement is applied into the practice production,the original roll profile precision can be guaranteed after grinding.
