针对某厂２０３０ｍｍ五机架冷连轧机颤振问题，从理论上揭示了轧机颤振同轧制液性能之间潜在的关系──轧制液性能影响轧机动态特性，从而改变轧机颤振的临界速度。在保证必要的润滑性、附着性等物化品质指标的特定条件下，适当控制轧制液浓度，即可消除颤振并提高轧速，解决了长期困扰生产的这一难题。 Aiming at the chatter of 2030mm 5-stand tandem cold rolling mill in a certain plant, the potential relationship between mill flutter and rolling liquid properties is theoretically revealed. The properties of rolling liquid affect the rolling mill dynamic characteristics and thus the rolling mill chatter criticality speed. Under the specific conditions of material and chemical quality indexes such as necessary lubricity and adhesiveness, proper control of the concentration of the rolling liquid can eliminate the chatter vibration and increase the rolling speed, thus solving the problem that long plagued the production.
