| Abstract: | The three dimensional flow field and temperature distribution in medium thick slab continuous casting mould of Tang Steel have been simulated by mathematical simulation soft. The influence of SEN config, casting speed, submerge depth and cross section on flow field and temperature distribution has been discussed. And the optimum SEN config and submerge depth were fixed based on the mathematical simulation and implication in production. The results show that the quality of slab has been improved and the operation of continuous casting has been stabled. |
