Evaluation of anti-seizure property in cold tandem mill of stainless steel

摘要

In order to produce the strip with high productivity in cold rolling of stainless steel, tandem mills have been used. Under the circumstance, tribological problems such as friction pick up and reduction of surface brightness occurred. The purposeof this study is to evaluate the anti-seizure property in cold rolling of stainless steel. In order to evaluate the property, evaluating system by means of the developed simulation testing machine by the author is used. The coefficient of friction and the limitation line of friction pick up are measured and the interface temperatures which the friction pick up occurs are calculated from the experimental data. From these results, the maximum rolling speed in actual tandem mill of stainless steel isestimated. By means of the evaluating system, it is estimated that the maximum rolling speed in tandem mill with lubricant having high lubricity is about 200 m/min.
