摘要
The application of the lubricant in the temper rolling process of tinplate manufacturing improves the mechanical properties and surface quality of the steel sheet.The removal of the residual lubricant deserves and has rarely been studied via numerical simulation.A simplified model of a single stand temper mill was established and was discretized into cells of block-structured grids.The criterion whether the lubricant could be removed was decided via multiphase simulation of a smaller model.Three parameters,the gap between the deflector and the rolls,the length of an additional baffle and the velocity of the purging air,were considered and scores of different working conditions were performed.The shapes of the steel sheet between the temper rolls and the bridle roll were also studied to screen out the conditions that the sheet could move steadily.
