Study On The Technical Problems Of Continuous Casting And Rolling For Aluminum Wire Rod

In this paper, the effects of the chemical composition, the technical parameters, microstructure and rolling design on the mechanical and electrical properties of pure aluminum wire rod are synthetically analyzed in the foundation of carrying through investigating practical production in-depth in TaiYuan aluminum factory, aiming at existent technical difficulty and some quality problem in the practical production. Byusing Gleeble-1500 thermo mechanical simulator, compressed test of purealuminum are made in certain temperature, at certain strain rate and strain. The mathematical models describing the relation among the flow stress and the deformed temperature, strain rate and strain are established and the relation among the recovery, the recrystallization of pure aluminum and the deformed temperature, strain rate and strain are analyzed. The machine used to produce aluminum wire rod - three rollers Y-type rolling mill are researched. This kind of rolling mode has many advantages, for example, high distortion efficiency, continuous production, high rate of finished product and good general performance. Through studying the three-roll machine, the important effect of the roller design on the production techniques is analyzed. And the computer aided roller design program has been worked out. With the program, the roller design may be in reason and become high efficiency. All these work can make a foundation and provide advantageous condition for the production technology renovatation.
