| Abstract: | A two dimensional heat transfer mathematical model, which describes the thermal process of slab hot transporting and hot charging, has been developed. The temperature change of slabs in the total transporting process has been tested by the hot tracing method. After verifying the accuracy and feasibility of the off line model, an on line control mathematical model has been developed. The results tested on the site show that results given by the on line model have advantages of continuity, accuracy and quickness. An on line computer management of thermal status parameters of continuous casting slabs has been realized. |
