就轧制变形区油膜厚度的不同测试方法进行了对比研究，提出了简便、实用的加热退火法。借此方法研究了轧制油粘度、轧制速度与压下率对轧制变形区油膜厚度的影响。
A comparative study on different test methods of oil film thickness in rolling deformation zone was made, and a simple and practical heating annealing method was put forward. By this method, the influence of rolling oil viscosity, rolling speed and reduction rate on the oil film thickness in the deformation zone was studied.
