The influence of tandem rolling process parameters on the texture and earing behaviour of AA1050
A novel combination of techniques, namely hot plane-strain compression (PSC) tests and laboratory cold rolling, was successfully applied to simulate the industrial practice for producing AA1050 sheets. Starting material for testing was taken from a hot rolled plate at transfer gauge between the breakdown and tandem mill. Three-stand hot tandem-rolling was simulated by means of hot plane-strain compression tests using a Thermal Mechanical Treatment Simulator (TMTS). Coil-cooling was simulated by means of a controlled cooling in a furnace. The hot deformed material was subsequently cold rolled on a laboratory mill. The influence of tandem rolling process parameters, such as entry temperature and strain rate on textures in different conditions and on the eating in the final annealed condition was investigated. A good agreement in the texture and eating value was found between the PSC-matetial and the production material, which makes this combination of techniques as a valuable way to evaluate the influences of industrial processing parameters on the final properties. It was found that the entry temperature has a stronger effect on the texture and eating than the strain rate.
