style="text-indent:25px">矯直處理目前只針對(duì)盤條鋼筋，由于盤條在鋼廠的軋制、收卷、熱處理、運(yùn)輸、堆放等過程中容易產(chǎn)生殘余應(yīng)力。而直條鋼筋相對(duì)盤條鋼筋情況大不相同，一般可直接投入生產(chǎn)。在工廠化的鋼筋加工中，鋼筋平直性尤為重要，其涉及后續(xù)的配送、彎曲、焊接等各項(xiàng)生產(chǎn)要素。目前的鋼筋矯直都是采用矯直機(jī)進(jìn)行矯直。蟬蛹的矯直機(jī)構(gòu)有兩種：輥式矯直機(jī)構(gòu)和旋轉(zhuǎn)式矯直機(jī)構(gòu)。輥式矯直機(jī)構(gòu)結(jié)構(gòu)較為簡(jiǎn)單，成本低，但矯直效果較差，對(duì)鋼筋內(nèi)部殘余應(yīng)力的去掉不夠徹底。旋轉(zhuǎn)矯直機(jī)構(gòu)結(jié)構(gòu)較為復(fù)雜，成本高，還需配備旋轉(zhuǎn)動(dòng)力能耗較高，但矯直效果好，對(duì)鋼筋的環(huán)向應(yīng)力去掉的較為徹底。這兩種矯直機(jī)構(gòu)在鋼筋加工設(shè)備上得到大量的應(yīng)用。</p><p

做好直輥的周期管理，若在周期內(nèi)有直輥表面涂料出現(xiàn)磨損，則需要重新進(jìn)行表面處理，以穩(wěn)定生產(chǎn)。高溫季節(jié)對(duì)個(gè)別紗線品種的直輥隨機(jī)進(jìn)行狀態(tài)抽查，保證紗線的質(zhì)量穩(wěn)定。5)
