    國外(wai)高(gao)效(xiao)率的石墨(mo)電(dian)極加(jia)工(gong)組合機床(chuang)都是用(yong)梳刀(dao)組合刀(dao)盤加(jia)工(gong)螺(luo)紋(wen)的,因而(er)炭素廠在(zai)編(bian)制(zhi)技能(neng)改造(zao)規(gui)劃的時(shi)分(fen)要把(ba)加(jia)工(gong)設備(bei)的改造(zao)放到必定(ding)方位(wei),有(you)條(tiao)件時(shi)置辦加(jia)工(gong)精(jing)度(du)有(you)保證(zheng)的組合機床(chuang)電極加(jia)工(gong)還(hai)應當(dang)註(zhu)重(zhong)查(zha)看量(liang)具(ju),不(bu)只要配(pei)備(bei)完善(shan)的量(liang)具(ju),對量具(如螺(luo)紋(wen)齒(chi)形樣(yang)板(ban))也要經常用(yong)更高(gao)檔(dang)的精(jing)細測量儀(yi)器(qi)加(jia)以校對運(yun)用(yong)錐形(xing)接(jie)頭聯接(jie)時(shi)應配(pei)備(bei)接(jie)頭栓等加(jia)固辦法(fa),由(you)於錐(zhui)形(xing)接(jie)頭如加(jia)工(gong)質(zhi)量(liang)稍(shao)差(cha),配(pei)合空(kong)隙(xi)略(lve)大(da)於規則誤(wu)差(cha),就(jiu)簡略(lve)松動(dong)脫扣導致(zhi)接(jie)頭或下端電極掉(diao)落,或在(zai)熔化期爐料塌(ta)落時(shi)接(jie)頭被撞斷,運(yun)用(yong)接頭栓等加(jia)固辦法(fa)將(jiang)有效(xiao)地削(xue)減松動(dong)掉落的可(ke)能(neng)性(xing)。國外(wai)多數炭素廠(chang)石墨(mo)電(dian)極出廠時已把(ba)接頭擰入石墨(mo)電(dian)極壹端的接(jie)頭孔內,保證(zheng)聯接(jie)出色,並且便於(yu)鋼廠(chang)煉鋼工(gong)接(jie)續(xu)電(dian)極。
