送(song)(song)电(dian)(dian)(dian)前首先把(ba)向石墨(mo)化炉(lu)(lu)(lu)通电(dian)(dian)(dian)的母线挂好,将(jiang)各(ge)个接(jie)(jie)点擦光、上(shang)紧。然后检(jian)查整个回(hui)路(lu)中是(shi)(shi)否有(you)开路(lu)或者(zhe)接(jie)(jie)地的情(qing)况(kuang)，冷却(que)水(shui)是(shi)(shi)否畅(chang)通，炉(lu)(lu)(lu)头粉(fen)是(shi)(shi)否填(tian)(tian)满。检(jian)查完毕，在(zai)炉(lu)(lu)(lu)上(shang)放上(shang)烟罩(zhao)，即可(ke)(ke)通知(zhi)送(song)(song)电(dian)(dian)(dian)。通电(dian)(dian)(dian)过程(cheng)中要经常巡视检(jian)查石墨(mo)化炉(lu)(lu)(lu)运(yun)行状态，炉(lu)(lu)(lu)头、炉(lu)(lu)(lu)尾导电(dian)(dian)(dian)电(dian)(dian)(dian)极及接(jie)(jie)点是(shi)(shi)否发(fa)(fa)红过热，炉(lu)(lu)(lu)子(zi)是(shi)(shi)否漏料(liao)和冒火，炉(lu)(lu)(lu)子(zi)是(shi)(shi)否出现(xian)(xian)接(jie)(jie)地，冷却(que)水(shui)是(shi)(shi)否出现(xian)(xian)堵塞，炉(lu)(lu)(lu)头和炉(lu)(lu)(lu)墙是(shi)(shi)否有(you)烧穿等。石墨(mo)化炉(lu)(lu)(lu)在(zai)运(yun)行过程(cheng)中发(fa)(fa)生的冒顶(ding)(冲(chong)顶(ding))现(xian)(xian)象，要立(li)即指(zhi)挥并配合天车用抓斗抓填(tian)(tian)充焦(jiao)(熟焦(jiao))进行覆(fu)盖，人(ren)要远离冒顶(ding)(冲(chong)顶(ding))处，以(yi)免(mian)发(fa)(fa)生烫伤事故。必(bi)要时可(ke)(ke)立(li)即停止(zhi)炉(lu)(lu)(lu)室(shi)供(gong)电(dian)(dian)(dian)及停止(zhi)高压电(dian)(dian)(dian)源供(gong)电(dian)(dian)(dian)。

石墨(mo)化(hua)产品(pin)质量(liang)的评价：石墨(mo)化(hua)后应按工序(xu)技术条件(jian)规定对产品(pin)进行外观检查和测量(liang)电阻率(lv)，然后取样送实验室测定真密度、体积密度、灰分、抗折强度、弹性模量(liang)和热膨胀系数(shu)等性能指(zhi)标。石墨(mo)化(hua)成品(pin)率(lv)的计算：石墨(mo)化(hua)品(pin)成品(pin)率(lv)是指(zhi)石墨(mo)化(hua)品(pin)的检验合格量(liang)占装人本期炉内焙(bei)烧品(pin)(含浸渍品(pin))的百(bai)分比。
