摘要
在四辊可逆冷轧机上用A,B,C和D 4种冷轧乳化液对St12带钢进行了轧制润滑工艺实验,分析比较了在相同轧制条件下4种轧制乳化液对轧制力、带钢表面反射率、带钢和轧辊表面温度等的影响规律.分析了轧制力和轧制速度的关系,利用实测轧制力数据和数学模型计算得到了摩擦因数.较好的油品润滑能力顺序为B,C,D和A,冷却能力顺序是A,C,D和B,带钢表面反射率顺序是B,D,C和A.实验研究结果对油品开发与评价,优化轧制润滑工艺参数和提高板面质量具有重要的理论和实际意义.
The experiments of lubrication process with the emulsions A,B,C and D as lubricating oil for the St12 strip rolling on a 4-high reversing cold mill were carried out.The effects of the four emulsions on the rolling force,strip surface reflectivity,surface temperature of strip rolls under the same rolling conditions were analyzed comparatively,as well as the relationship between rolling force and rolling speed.Moreover,the friction coefficient was calculated with the measured data of rolling force by a mathematical model.It was revealed that the sequences of the emulsions from first to last in relation to the lubrication quality,cooling performance and strip surface reflectivity are B-C-D-A,A-C-D-B and B-D-C-A,respectively.The experimental results are of theoretical and practical importance to the development and evaluation of rolling oil,optimization of rolling-lubricating process parameters and improvement of strip steel surface quality.
