Design of small and middle diameter copper bar rolling mill pass system

The copper wire stock rolling mill line is the key equipment of small and middle diameter light and low oxgen copper bar manufacture.The rolling technology is crucial to ensuring the production quality.Based on copper plastic processing features,the metal rolling theory and the practical procedure,the paper presents the design method of the copper bar rolling mill pass system and the calculation methods of the factors.Some key factors,such as the elongation factor and filling metal degree through the pass system at every rolling segment,and some dynamic factors are calculated for small and middle copper bar roiling mills.The test result shows that the design method can reduce the procedure errors,improve the product quality and prolong the rolls life.The presented work is a good help to the design of rolling mills.
