连铸中间包多孔导流墙结构优化

Optimization of Porous Diversion Wall Structure in Continuous Casting Tundish

以某钢厂连铸中间包为研究对象,采用正交试验法对中间包多孔导流墙结构进行研究。通过RTD曲线计算结果和极差分析,得出了最优的装置控流方案:挡墙中心到长水口中心距离为1 550mm,导流孔直径为100mm,导流孔上仰角为35°,上、下孔间距为240mm。

Porous diversion wall structure of a continuous casting tundish was optimized by the orthogonal experiment.Based on RTD curve calculation results and range analysis,the optimized fluid-control parameters were presented as follows：retaining wall center distances from the center of the tundish of1 550 mm,the diversion hole diameter of 100 mm and the diversion hole on the elevation of 35°,up and down hole distance of 240 mm.
