This kind of rectangular pass is with significant characteristics,not only large hatch,shallow depth,small difference of velocity,but also less wear,small deformation resistance,light spin degree and with good appearance.
这样设计的方矩形管孔型优点突出,不仅孔型开口大、深度浅、线速度差小,而且孔型磨损小、变形阻力小、打滑程度轻、方矩形管表面质量好。
The relationship of deformation resistance,degree and rate was studied by means of Gleeble-2000 thermal simulator.
借助Gleeble-2000型热模拟试验机,研究了微合金高强度钢在热变形过程中变形阻力与变形温度、变形程度和应变速率之间的关系,并分析了加热温度对晶粒度的影响。
