试验及生产实践说明:对有相变再结晶钢晶粒细化的历史经验不完全可靠。相变温度A_(cl)以上的加热速度对晶粒度有决定性的影响。每一个钢号,有一个获得可靠细晶粒的临界加热速度。利用相变再结晶及栅控理论的联合作
Test and production practice shows that the history of phase transformation of recrystallized steel grain refining experience is not entirely reliable. The heating rate above the phase change temperature A_ (cl) has a decisive influence on grain size. For each steel grade, there is a critical heating rate for reliable fine grain. The use of phase transition recrystallization and gating theory of joint work
