Several rate reduction的意思|示意

The effects on RH decarburization of several parameters including lift gas flow rate, vacuum pressure reduction curves, KTB starting time and initial carbon and oxygen content are investigated.

考察了提升气体流量、真空度压降模式、KTB吹氧时机以及初始碳氧含量对RH脱碳的影响。

The uniformity of deformation during hot rolling could be improved by properly increasing the slab thickness and adopting large reduction rate in first several rolling passes.

适量增加铸坯厚度，并在较靠前的机架分配较大的压下量有利于提高轧制过程的应变均匀性。
