连铸工艺参数正交试验模拟优化

Application of Orthogonal Test on Technology Parameter Optimization in Continuous Casting Process

影响结晶器内流场的主要参数有浸入式水口倾角、水口的浸入深度、板坯尺寸,以及拉坯速度。运用模拟软件的模拟结果只能显示某个参数的影响规律,不能得到最佳的工艺参数组合。运用正交试验法对模拟结果进行优化,结果显示,该参数组合下的结晶器内流场十分稳定。有利于避免钢液卷渣现象的发生。

The main parameters which effect the fluid field in the water cooling mould is outflow angel, depth of submerged entry nozzle, slab dimension and casting speed. The result from the simulation software can only get effect regularity about one parameter, not the best parameters combination. This paper will optimize the simulation results with orthogonal test. With the parameters combination get the stable flow field in the water cooling mould.
