石(shi)(shi)(shi)(shi)墨(mo)(mo)化(hua)(hua)爐(lu)(lu)(lu)在(zai)(zai)(zai)(zai)運行中(zhong)(zhong),爐(lu)(lu)(lu)溫(wen)達2300℃以上(shang),導(dao)電(dian)(dian)電(dian)(dian)極與(yu)爐(lu)(lu)(lu)芯(xin)連(lian)結(jie)(jie)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)一(yi)(yi)(yi)端就是(shi)(shi)(shi)在(zai)(zai)(zai)(zai)這(zhe)(zhe)(zhe)樣的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)高(gao)(gao)溫(wen)下進行工(gong)作。導(dao)電(dian)(dian)電(dian)(dian)極的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)另一(yi)(yi)(yi)端與(yu)銅(tong)(tong)母線(xian)相(xiang)(xiang)連(lian)接(jie)(jie),這(zhe)(zhe)(zhe)就要(yao)(yao)保證與(yu)銅(tong)(tong)板的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)連(lian)接(jie)(jie)處(chu)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)溫(wen)度要(yao)(yao)低(di)于(yu)銅(tong)(tong)板的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)融化(hua)(hua)溫(wen)度,同(tong)時(shi)(shi),因導(dao)電(dian)(dian)電(dian)(dian)極裸露在(zai)(zai)(zai)(zai)空氣中(zhong)(zhong),必須在(zai)(zai)(zai)(zai)低(di)于(yu)氧化(hua)(hua)溫(wen)度下工(gong)作。為此,一(yi)(yi)(yi)定(ding)(ding)要(yao)(yao)進行強制(zhi)冷(leng)(leng)卻(que)。目前基本(ben)有兩種(zhong)(zhong)冷(leng)(leng)卻(que)方(fang)式(shi)(shi)。   1、直(zhi)接(jie)(jie)淋(lin)水(shui)(shui)(shui)冷(leng)(leng)卻(que):   以鉆孔水(shui)(shui)(shui)管(guan)橫架(jia)于(yu)導(dao)電(dian)(dian)電(dian)(dian)極上(shang),澆(jiao)水(shui)(shui)(shui)于(yu)導(dao)電(dian)(dian)電(dian)(dian)極及(ji)其與(yu)銅(tong)(tong)母線(xian)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)連(lian)接(jie)(jie)處(chu),使(shi)之冷(leng)(leng)卻(que)。這(zhe)(zhe)(zhe)種(zhong)(zhong)直(zhi)接(jie)(jie)冷(leng)(leng)卻(que)方(fang)式(shi)(shi)簡單、方(fang)便,冷(leng)(leng)卻(que)效果(guo)好。缺點(dian)是(shi)(shi)(shi),冷(leng)(leng)卻(que)水(shui)(shui)(shui)四濺,易對爐(lu)(lu)(lu)體(ti)滲水(shui)(shui)(shui)。而(er)且這(zhe)(zhe)(zhe)種(zhong)(zhong)方(fang)式(shi)(shi)需(xu)要(yao)(yao)安裝一(yi)(yi)(yi)泄(xie)水(shui)(shui)(shui)槽(cao),水(shui)(shui)(shui)槽(cao)易阻塞,不(bu)(bu)(bu)及(ji)時(shi)(shi)處(chu)理,槽(cao)內水(shui)(shui)(shui)就容易滲入(ru)爐(lu)(lu)(lu)內,噴(pen)淋(lin)水(shui)(shui)(shui)也容易滲入(ru)爐(lu)(lu)(lu)內,使(shi)爐(lu)(lu)(lu)子的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)壽命周期縮(suo)短,同(tong)時(shi)(shi)易使(shi)爐(lu)(lu)(lu)內產品氧化(hua)(hua)。另外,在(zai)(zai)(zai)(zai)北方(fang),冬季水(shui)(shui)(shui)槽(cao)四周容易結(jie)(jie)冰較(jiao)多,不(bu)(bu)(bu)易處(chu)理。   2、直(zhi)接(jie)(jie)內冷(leng)(leng):   在(zai)(zai)(zai)(zai)導(dao)電(dian)(dian)電(dian)(dian)極鏜孔后直(zhi)接(jie)(jie)用絲(si)堵堵上(shang),再(zai)(zai)接(jie)(jie)上(shang)一(yi)(yi)(yi)長(chang)一(yi)(yi)(yi)短兩根(gen)水(shui)(shui)(shui)管(guan),讓水(shui)(shui)(shui)直(zhi)接(jie)(jie)流到電(dian)(dian)極的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)圓孔后再(zai)(zai)排(pai)出,從(cong)上(shang)述意義(yi)講(jiang),人(ren)(ren)造(zao)石(shi)(shi)(shi)(shi)墨(mo)(mo)只能稱作一(yi)(yi)(yi)種(zhong)(zhong)“多晶石(shi)(shi)(shi)(shi)墨(mo)(mo)”。不(bu)(bu)(bu)過這(zhe)(zhe)(zhe)種(zhong)(zhong)“多晶石(shi)(shi)(shi)(shi)墨(mo)(mo)”已具備(bei)了(le)(le)理想石(shi)(shi)(shi)(shi)墨(mo)(mo)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)基本(ben)特(te)性。

  這(zhe)(zhe)(zhe)種(zhong)(zhong)方(fang)式(shi)(shi)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)優(you)點(dian)是(shi)(shi)(shi)易將水(shui)(shui)(shui)系(xi)統(tong)做(zuo)成(cheng)(cheng)全封閉或半(ban)(ban)封閉系(xi)統(tong),不(bu)(bu)(bu)會向爐(lu)(lu)(lu)內滲入(ru)。因為可以不(bu)(bu)(bu)用泄(xie)水(shui)(shui)(shui)槽(cao),從(cong)而(er),用此方(fang)法(fa)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)廠家,多把水(shui)(shui)(shui)系(xi)統(tong)做(zuo)成(cheng)(cheng)半(ban)(ban)封閉系(xi)統(tong)。缺點(dian)是(shi)(shi)(shi):冷(leng)(leng)卻(que)效果(guo)不(bu)(bu)(bu)如直(zhi)接(jie)(jie)淋(lin)水(shui)(shui)(shui)冷(leng)(leng)卻(que),對水(shui)(shui)(shui)質(zhi)要(yao)(yao)求較(jiao)高(gao)(gao),嚴禁缺水(shui)(shui)(shui)。否則爐(lu)(lu)(lu)頭(tou)溫(wen)度升高(gao)(gao),再(zai)(zai)忽然通入(ru)冷(leng)(leng)水(shui)(shui)(shui),易產生(sheng)水(shui)(shui)(shui)爆,十分(fen)危險。

固(gu)(gu)定(ding)(ding)式(shi)(shi)側(ce)(ce)墻(qiang)(qiang)一(yi)(yi)(yi)般采用耐火(huo)(huo)磚(zhuan)砌筑(zhu),每隔一(yi)(yi)(yi)定(ding)(ding)間隔都(dou)要(yao)(yao)留一(yi)(yi)(yi)排(pai)氣孔,以使(shi)送電(dian)(dian)過程中(zhong)(zhong)爐(lu)(lu)(lu)芯(xin)內的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)煙氣能順利排(pai)出。使(shi)用耐火(huo)(huo)磚(zhuan)做(zuo)側(ce)(ce)墻(qiang)(qiang),保溫(wen)效果(guo)好,使(shi)用壽命也稍長(chang),但造(zao)價(jia)(jia)較(jiao)高(gao)(gao)。   活動式(shi)(shi)側(ce)(ce)墻(qiang)(qiang)是(shi)(shi)(shi)由(you)水(shui)(shui)(shui)泥(ni)、粘土(tu)、耐火(huo)(huo)磚(zhuan)碎塊等按一(yi)(yi)(yi)定(ding)(ding)比例(li)配(pei)制(zhi)而(er)成(cheng)(cheng),墻(qiang)(qiang)上(shang)留有排(pai)氣孔。使(shi)用時(shi)(shi)將活動側(ce)(ce)墻(qiang)(qiang)吊放在(zai)(zai)(zai)(zai)爐(lu)(lu)(lu)兩側(ce)(ce)、由(you)槽(cao)鋼做(zuo)成(cheng)(cheng)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)柱子間。活動式(shi)(shi)側(ce)(ce)墻(qiang)(qiang)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)優(you)點(dian)是(shi)(shi)(shi)經濟、省工(gong),且冷(leng)(leng)卻(que)爐(lu)(lu)(lu)子時(shi)(shi)方(fang)便。缺點(dian)是(shi)(shi)(shi)不(bu)(bu)(bu)耐機械(xie)沖(chong)擊和(he)熱沖(chong)擊,以及(ji)破損不(bu)(bu)(bu)能修(xiu)補(bu)等。   此外,現在(zai)(zai)(zai)(zai)還出現了(le)(le)下半(ban)(ban)部為固(gu)(gu)定(ding)(ding)式(shi)(shi),上(shang)半(ban)(ban)部為活動式(shi)(shi)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)混合型側(ce)(ce)墻(qiang)(qiang),兼顧了(le)(le)兩者的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)優(you)點(dian),使(shi)用效果(guo)比較(jiao)理想。槽(cao)鋼(或鑄鐵(tie)支架(jia))主要(yao)(yao)起固(gu)(gu)定(ding)(ding)側(ce)(ce)墻(qiang)(qiang)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)作用。通電(dian)(dian)爐(lu)(lu)(lu)芯(xin)由(you)被加(jia)熱的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)產品和(he)中(zhong)(zhong)間填充(chong)電(dian)(dian)阻料組(zu)成(cheng)(cheng)。通電(dian)(dian)后爐(lu)(lu)(lu)體(ti)有一(yi)(yi)(yi)定(ding)(ding)的(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)(de)熱脹(zhang)力。
