style="text-indent:25px">碾環(huán)機講述4、加工硬化雖然能夠提**度，但卻降低塑性，這對于大變形量的變形加工無疑會帶來麻煩，如鋼絲變徑的拉拔。如果要求變徑較大，因加工硬化現(xiàn)象的存在就不能一次拉**，需要多次拉拔，而且在兩次拉拔之間必須安排去除加工硬化的退火處理，使鋼絲的塑性恢復(fù)才能再進行下一次拉拔變徑。比如，對于加工硬化敏感的材料如高錳鋼，由于加工硬化現(xiàn)象的存在使其難以進行切削加工。5、鍛件塑性變形不僅使鍛件機械性能明顯變化，也明顯改變鍛件的物理、化學(xué)性能，例如，使電阻增大，導(dǎo)磁性、耐腐蝕性降低等。供參考，相信大家對于這些知識都了解了吧，敬請關(guān)注我們的網(wǎng)站，之后還會陸續(xù)的更新。數(shù)控碾環(huán)機主要用于減速機、工程機械、石油機械，船舶機械、農(nóng)業(yè)機械等行業(yè)。</p><div
