摘　　要：在理化性能与摩擦学性能测试分析的基础上,对CSP热轧板带钢工艺润滑应用效果进行轧制过程研究。工业应用试验表明:CSP热轧板带钢过程中,并非热轧油体积比越高,工艺润滑效果越好,选择中低黏度、润滑性能良好的热轧油,其体积分数在0.2%时即可平均降低轧制力10%～20%,使连轧过程张力波动控制在20%以内,同时对冷却水的污染也不明显。摩擦学测试和轧制工艺润滑应用试验数据分析表明,控制热轧油体积分数在1%以下即可满足热轧工艺润滑作用效果。可根据具体轧制产品与工艺对热轧油黏度和用量做出相应调整,应以保证CSP热轧生产平稳进行和对冷却水少污染为评价标准,而并非轧制压力的降低值。The effect of lubrication during hot rolling of compact strip production （CSP） was studied based on the physical-chemical properties and tribological characteristics test of hot rolling oils. The application test of lubrication in hot rolling shows that the lubricating effect does not always gets better as hot rolling oil concentration increases. Choosing the hot rolling oil with moderate viscosity and excellent lubrication performance, and with a volume ratio 0. 2% of the oil, the average rolling force would decrease by 10% - 20% , the continuing rolling tension could be controlled in 20% of fluctuation, and the cooling water pollution is not obvious. The tribological experiments and analysis of rolling lubrication application data further explain that no more than 1% of the volume ratio of hot rolling oil would meet the lubricating effect in hot rolling of CSP. According to the specific strips and hot rolling process, the viscosity and consumption of hot rolling oil should be adjusted accordingly to ensure stable hot rolling of CSP and minimum cooling water pollution for evaluation standards, rather than how much rolling force to reduce.
