Design Method of Secondary Cooling System for Slab Continuous Casting Based on Heat-transfer Model Simulation
The secondary cooling system for the new slab caster of certain steel plant was optimized by secondary cooling optimum design module of static simulation software CCPS OFFLINE for slab continuous casting process based on the specific and reasonable curve of targetsurface temperature.Through the inverse heat-transfer simulation,the secondary cooling water tables were obtained for diverse slab thickness and steel grade group,and some important secondary cooling parameters,such as specific water flow,water distribution proportion of each spraying circuit,flowrate range and adjusting multiple of spraying nozzle,were also analyzed comprehensively.
