【摘要】：結(jié)合實(shí)際生產(chǎn)S35C成分精沖鋼,討論了亞共析熱軋鋼板片狀滲碳體的退火球化行為及轉(zhuǎn)變機(jī)制,并采用Gleeble熱模擬試驗(yàn)機(jī)研究了熱軋和冷軋變形量對(duì)精沖鋼片狀滲碳體快速球化效果的影響。結(jié)果表明,與850℃30%應(yīng)變量相比,60%大變形量可有效細(xì)化組織,促進(jìn)層片狀珠光體斷裂,顯著加快熱軋板球化速率,提高粒狀滲碳體的均勻分布。冷軋大變形也有利于片狀滲碳體的快速球化退火,但50%過(guò)高應(yīng)變量會(huì)導(dǎo)致鋼板退火后難以消除加工硬化,S35C精沖鋼冷軋合適的變形量約在40%。
[Abstract]:The annealing spheroidization behavior and transformation mechanism of sheet cementite of hypoeutectoid hot rolled steel plate were discussed in connection with the actual production of S35C fine blanking steel.The effect of hot rolling and cold rolling on the rapid spheroidization of finely punched steel sheet cementite was studied by Gleeble thermal simulation machine.The results show that compared with the strain of 30% at 850 鈩，
