| Abstract: | This paper concentrates on secondary cooling design of slab caster based on the ultrahigh strength steel （ UHSS） .Firstly, a mathematical heat transfer model to describe the solidification process of continu-ously cast slab has been developed .Secondly, the aimed slab surface temperatures were determined according to the high temperature plastic curves and the metallurgical principles in the secondary cooling zone .Finally, with the tar-get temperature on the slab surface , use the incremental PID algorithm adjust the water flow in each loop of secondary cooling zone. |
