在加拿大魁北克州索雷尔-特雷西的RTIT(QIT)工厂正在运行的三角形四流方坯连铸机中间包的全尺寸水模型上进行了数学建模。中间包已经使用了由麦吉尔金属加工中心(MMPC)设计的大而浅的冲击垫，并被证明是相当成功的。在这项研究中，研究了12种不同的流动改进剂组合，每种组合都包括标准冲击垫和位于内股和外股之间的两个坝。此外，将SIP的大小分四个步骤进行了变化，并对其性能进行了评估。计算了所有18个设计的残留包含率(RRI)，并确定了最佳构型。对于几个设计，用现有的水模型数据验证了数学预测的RRI值。
Mathematical modelling was performed on a full scale aqueous model of a delta shaped four-strand billet caster tundish that is in operation at the RTIT (QIT) plant in Sorel-Tracy, Que., Canada. The tundish already uses a large and shallow impact pad designed by the McGill Metals Processing Centre (MMPC) and has proved to be quite successful. In the present study, 12 different combinations of flow modifiers were researched, each of which consisted of the standard impact pad (SIP) and two dams located in between the inner and outer strands. In addition, the size of the SIP was varied in four steps, and its performance was evaluated. The residual ratio of inclusion (RRI) was calculated for all 18 designs, and the best configuration was identified. Mathematically predicted RRI values were verified with existing water model data for a couple of designs.
