压缩的

When the equivalent strain rate is relatively low, this influence can be neglected and the compression process can be considered as an isothermal process. While the equivalent strain rate is high, this influence is of importance and the compression process can be approximately considered as an adiabatic process.

当等效应变速率很小时，变形热效应对流动应力的影响可忽略不计，压缩过程可近似认为是等温过程；当等效应变速率较大时，变形热效应对流动应力的影响相当显著，压缩过程基本上成为绝热过程。

The experiment and the research indicate that:(1) Through the Hot-Continuous-Rolling production technics under small reduction ratio of 4.04 and 5.08, the rectangular continuous-casting billet of 235×265mm can be used to produce big size steel stick of Φ140mm and Φ 125mm whose macrostructure and mechanical properties meet the standards, this technics is viable;(2) This rolling technics can make the deformation penetrate to the center of the billet by low temperture and low velocity and big roller diameter and large reduction quantity at every pass and optimum design and arrangement of rollers, which is the key of Hot-Continuous-Rolling technics under small reduction ratio;(3) The sending technics used in Xining Special Steel Co.,Ltd can not use waste-heat of billet adequately, but the sensitive temperature section of A1N or sulphides or inclusions separating out is avoided, creating a favorablecondition for insuring good surface quality of final rolled steel;(4) The Hot-Continuous-Rolling technics under small reduction ratio has a close relationship with the billet quality control and the hot sending process control and the cooling control after rolling.
