本试验采用不同包铝方式，不同加热时间，不同轧制道次和道次压下量的安排进行研究。
Various alclad, heating time, rolling pass, reduction is used in the test, and compared surface quality with rate of finished product after rolling.
在带材制备过程中，冷拉以后不退火直接轧制，采用大的道次压下量，均有利于提高临界电流。
During preparing silve sheathed tape, rolling after cold drawing without annealing, adopting large draught perpass were both benefit improving Jc.
因此，以降低轧制功率为目标，优化设计道次压下量以取得降低能耗的目的，有着积极的作用和意义。
So it is very meaningful to optimize the assign of reduction, as to reduce power consuming index.
