Optimization And Design Of "1+4" Aluminum Strip Hot Rolling Schedule

With the rapid development of aluminum industry, aluminum alloy products is usedin various fields and not just confined to the field of military, becoming one of the pillarindustries of most countries and regions. As a veritable aluminum industry superpower,our country must improve yield and quality requirements. For the complex system, onlythe reasonable rolling schedule can assure manufacturability, safety, and reliability.When slipping appeared in the process of aluminum processing, the product qualityand production will be affected. In this paper practical forward slip model is established,which is based on analyzing the influence of parameters on the forward slip, and the newjudgment method for slipping is established. All of these become theoretical basis forpreventing slipping rolling schedules setup.The load distribution is the essential question in rolling schedule setup.Φfunctionload distribution is a simple and practical method for hot tandem rolling. This paperprovides a method to judge slipping and establishes a multi-objective function with similardegree of power residual and preventing the slip phenomenon. Fruit fly optimizationalgorithm is used to optimize the reduction rate of first three stands. The optimizedschedule is applied to roll5052aluminum alloy of1+4aluminum hot rolling machine ofaluminum plant in Henan, and the performance is satisfied. ThenΦfunction loaddistribution is applied to the optimized schedule and the results show that the effectivenessof this method.Finally, C#and Matlab mixed programming be studied, human machine interface bedesigned to applying theory to practice.
