Research on rolling force model in hot-rolling process of aluminum alloys

On the basis of classic rolling-theory, a rolling force model of AA5052 aluminum alloys during hot rough rolling was investigated. Factors which influenced rolling force in the process including radius of elastic flattened roll, stress state coefficient and deformation resistance were evaluated in detail to establish the model. The rolling force prediction program was developed by means of MATLAB and the comparison between calculations and measured values of the rolling force indicated that the rolling force model has good prediction precision with an error between 5%∼7% and it can meet the basic requirements of the actual production site.
