style="text-indent:25px">封頭等到冷卻結(jié)束之后，心部的冷卻體積也不能進(jìn)行自由的收縮，會(huì)讓材料和熱處理工藝受到影響。如果冷度速度快，那么相對(duì)的碳含量和合金量也越高，在進(jìn)行冷卻的時(shí)候存在不均勻塑形的幾率越高，會(huì)形成殘余應(yīng)力的可能性也越大。其實(shí)封頭的變大都表現(xiàn)在表層的受應(yīng)拉力、心部受壓應(yīng)力，這都和熱應(yīng)力是相反的，所以說(shuō)應(yīng)力的大小和冷卻速度、形狀、材料的化學(xué)成分有關(guān)。封頭是安裝在一定體積的容器上的時(shí)候，要求其盡可能的起到密封的效果。封頭以增大執(zhí)行機(jī)構(gòu)的輸出推力。蘇州除塵設(shè)備封頭</p><p
