tandem selection

Study on type selection for new cold strip tandem mill

新建冷带连轧机机型选择和配置方案研究

The selection of main driving motor and main driving control system for the line were induced in dealing with the problems existed in the commissioning of 1+ 4 hot tandem rolling line imported by SWA.

针对中铝西南铝引进的（1+4）热连轧生产线安装调试问题，重点对该生产线主传动电机及主传动控制系统的方案选择进行介绍。

The results of this study indicate: ( 1) Index selection is more efficient than tandem selection or independent culling levels.

比较了逐项选择法、独立淘汰水平法、估计指数法和基本指数法四种不同选择方法的选择效率。试验表明，指数选择法最为有效，基本指数法和估计指数法同样有效。
