  石(shi)(shi)墨(mo)化(hua)(hua)(hua)(hua)爐(lu)(lu)(lu)(lu)(lu)的(de)(de)冷(leng)卻(que)(que)(que)(que)(que)(que)方(fang)法(fa)   石(shi)(shi)墨(mo)化(hua)(hua)(hua)(hua)爐(lu)(lu)(lu)(lu)(lu)在(zai)運行(xing)中(zhong)(zhong),爐(lu)(lu)(lu)(lu)(lu)溫達2300℃以(yi)上(shang)(shang),導(dao)電(dian)(dian)電(dian)(dian)極(ji)與爐(lu)(lu)(lu)(lu)(lu)芯連(lian)(lian)結(jie)的(de)(de)一(yi)端就(jiu)是在(zai)這(zhe)樣的(de)(de)高(gao)(gao)(gao)溫下進行(xing)工作(zuo)(zuo)。導(dao)電(dian)(dian)電(dian)(dian)極(ji)的(de)(de)另(ling)一(yi)端與銅(tong)母線相連(lian)(lian)接(jie)(jie),這(zhe)就(jiu)要(yao)保(bao)證與銅(tong)板的(de)(de)連(lian)(lian)接(jie)(jie)處(chu)的(de)(de)溫度(du)(du)(du)要(yao)低(di)于(yu)(yu)銅(tong)板的(de)(de)融化(hua)(hua)(hua)(hua)溫度(du)(du)(du),同(tong)時(shi),因導(dao)電(dian)(dian)電(dian)(dian)極(ji)裸露在(zai)空(kong)(kong)氣(qi)(qi)中(zhong)(zhong),必須在(zai)低(di)于(yu)(yu)氧化(hua)(hua)(hua)(hua)溫度(du)(du)(du)下工作(zuo)(zuo)。為(wei)(wei)此,一(yi)定(ding)要(yao)進行(xing)強制冷(leng)卻(que)(que)(que)(que)(que)(que)。目前基(ji)本有兩(liang)(liang)種(zhong)(zhong)冷(leng)卻(que)(que)(que)(que)(que)(que)方(fang)式(shi)。   1、直接(jie)(jie)淋(lin)(lin)水(shui)(shui)(shui)(shui)冷(leng)卻(que)(que)(que)(que)(que)(que):   以(yi)鉆孔水(shui)(shui)(shui)(shui)管橫架(jia)于(yu)(yu)導(dao)電(dian)(dian)電(dian)(dian)極(ji)上(shang)(shang),澆水(shui)(shui)(shui)(shui)于(yu)(yu)導(dao)電(dian)(dian)電(dian)(dian)極(ji)及其(qi)與銅(tong)母線的(de)(de)連(lian)(lian)接(jie)(jie)處(chu),使之冷(leng)卻(que)(que)(que)(que)(que)(que)。這(zhe)種(zhong)(zhong)直接(jie)(jie)冷(leng)卻(que)(que)(que)(que)(que)(que)方(fang)式(shi)簡單、方(fang)便,冷(leng)卻(que)(que)(que)(que)(que)(que)效(xiao)果(guo)好(hao)(hao)。缺點(dian)是,冷(leng)卻(que)(que)(que)(que)(que)(que)水(shui)(shui)(shui)(shui)四濺,易(yi)(yi)(yi)(yi)對爐(lu)(lu)(lu)(lu)(lu)體(ti)滲水(shui)(shui)(shui)(shui)。而(er)且這(zhe)種(zhong)(zhong)方(fang)式(shi)需(xu)要(yao)安裝一(yi)泄水(shui)(shui)(shui)(shui)槽(cao),水(shui)(shui)(shui)(shui)槽(cao)易(yi)(yi)(yi)(yi)阻塞,不及時(shi)處(chu)理(li),槽(cao)內(nei)(nei)(nei)水(shui)(shui)(shui)(shui)就(jiu)容(rong)易(yi)(yi)(yi)(yi)滲入(ru)爐(lu)(lu)(lu)(lu)(lu)內(nei)(nei)(nei),噴(pen)淋(lin)(lin)水(shui)(shui)(shui)(shui)也容(rong)易(yi)(yi)(yi)(yi)滲入(ru)爐(lu)(lu)(lu)(lu)(lu)內(nei)(nei)(nei),使爐(lu)(lu)(lu)(lu)(lu)子(zi)的(de)(de)壽命周期縮(suo)短,同(tong)時(shi)易(yi)(yi)(yi)(yi)使爐(lu)(lu)(lu)(lu)(lu)內(nei)(nei)(nei)產(chan)品氧化(hua)(hua)(hua)(hua)。另(ling)外,在(zai)北方(fang),冬季水(shui)(shui)(shui)(shui)槽(cao)四周容(rong)易(yi)(yi)(yi)(yi)結(jie)冰較(jiao)多(duo)(duo)(duo),不易(yi)(yi)(yi)(yi)處(chu)理(li)。   2、直接(jie)(jie)內(nei)(nei)(nei)冷(leng):   在(zai)導(dao)電(dian)(dian)電(dian)(dian)極(ji)鏜孔后直接(jie)(jie)用(yong)(yong)絲堵(du)堵(du)上(shang)(shang),再(zai)接(jie)(jie)上(shang)(shang)一(yi)長一(yi)短兩(liang)(liang)根水(shui)(shui)(shui)(shui)管,讓水(shui)(shui)(shui)(shui)直接(jie)(jie)流到(dao)電(dian)(dian)極(ji)的(de)(de)圓(yuan)孔后再(zai)排(pai)出,從(cong)上(shang)(shang)述意義講,人(ren)造(zao)石(shi)(shi)墨(mo)只(zhi)能稱作(zuo)(zuo)一(yi)種(zhong)(zhong)“多(duo)(duo)(duo)晶(jing)(jing)石(shi)(shi)墨(mo)”。不過這(zhe)種(zhong)(zhong)“多(duo)(duo)(duo)晶(jing)(jing)石(shi)(shi)墨(mo)”已具備了(le)理(li)想石(shi)(shi)墨(mo)的(de)(de)基(ji)本特性(xing)(xing)。   3、金(jin)(jin)剛石(shi)(shi)的(de)(de)晶(jing)(jing)體(ti)結(jie)構(gou)   在(zai)金(jin)(jin)剛石(shi)(shi)的(de)(de)晶(jing)(jing)體(ti)結(jie)構(gou)中(zhong)(zhong)每個碳原子(zi)與相鄰(lin)的(de)(de)四個碳原子(zi)以(yi)共價鍵結(jie)合,呈正(zheng)四面體(ti)配位,屬于(yu)(yu)等軸(zhou)晶(jing)(jing)系(xi)(xi),金(jin)(jin)剛石(shi)(shi)是典型的(de)(de)原子(zi)晶(jing)(jing)體(ti),金(jin)(jin)剛石(shi)(shi)的(de)(de)這(zhe)種(zhong)(zhong)結(jie)構(gou)特征,決定(ding)了(le)金(jin)(jin)剛石(shi)(shi)不導(dao)電(dian)(dian),導(dao)熱(re)(re)性(xing)(xing)也很(hen)差。在(zai)隔(ge)絕(jue)空(kong)(kong)氣(qi)(qi)的(de)(de)條件下加(jia)熱(re)(re)到(dao)1000℃時(shi),金(jin)(jin)剛石(shi)(shi)轉變為(wei)(wei)石(shi)(shi)墨(mo)結(jie)構(gou),在(zai)空(kong)(kong)氣(qi)(qi)中(zhong)(zhong)加(jia)熱(re)(re)到(dao)780℃左右會燃燒而(er)生成(cheng)(cheng)(cheng)二氧化(hua)(hua)(hua)(hua)碳。使用(yong)(yong)純度(du)(du)(du)較(jiao)高(gao)(gao)(gao)的(de)(de)人(ren)造(zao)石(shi)(shi)墨(mo)在(zai)高(gao)(gao)(gao)溫、高(gao)(gao)(gao)壓下可以(yi)獲得人(ren)造(zao)金(jin)(jin)剛石(shi)(shi),但是這(zhe)種(zhong)(zhong)人(ren)造(zao)金(jin)(jin)剛石(shi)(shi)的(de)(de)顆粒比較(jiao)小。   這(zhe)種(zhong)(zhong)方(fang)式(shi)的(de)(de)優(you)點(dian)是易(yi)(yi)(yi)(yi)將水(shui)(shui)(shui)(shui)系(xi)(xi)統做(zuo)成(cheng)(cheng)(cheng)全封(feng)(feng)閉(bi)或半封(feng)(feng)閉(bi)系(xi)(xi)統,不會向爐(lu)(lu)(lu)(lu)(lu)內(nei)(nei)(nei)滲入(ru)。因為(wei)(wei)可以(yi)不用(yong)(yong)泄水(shui)(shui)(shui)(shui)槽(cao),從(cong)而(er),用(yong)(yong)此方(fang)法(fa)的(de)(de)廠家,多(duo)(duo)(duo)把水(shui)(shui)(shui)(shui)系(xi)(xi)統做(zuo)成(cheng)(cheng)(cheng)半封(feng)(feng)閉(bi)系(xi)(xi)統。缺點(dian)是:冷(leng)卻(que)(que)(que)(que)(que)(que)效(xiao)果(guo)不如直接(jie)(jie)淋(lin)(lin)水(shui)(shui)(shui)(shui)冷(leng)卻(que)(que)(que)(que)(que)(que),對水(shui)(shui)(shui)(shui)質要(yao)求較(jiao)高(gao)(gao)(gao),嚴禁缺水(shui)(shui)(shui)(shui)。否則爐(lu)(lu)(lu)(lu)(lu)頭溫度(du)(du)(du)升(sheng)高(gao)(gao)(gao),再(zai)忽然通入(ru)冷(leng)水(shui)(shui)(shui)(shui),易(yi)(yi)(yi)(yi)產(chan)生水(shui)(shui)(shui)(shui)爆,十分危險。   石(shi)(shi)墨(mo)化(hua)(hua)(hua)(hua)爐(lu)(lu)(lu)(lu)(lu)側(ce)(ce)墻(qiang)(qiang)(qiang)分固定(ding)墻(qiang)(qiang)(qiang)和(he)活(huo)動(dong)(dong)(dong)墻(qiang)(qiang)(qiang)   固定(ding)式(shi)側(ce)(ce)墻(qiang)(qiang)(qiang)一(yi)般采用(yong)(yong)耐(nai)火(huo)磚砌筑(zhu),每隔(ge)一(yi)定(ding)間(jian)隔(ge)都要(yao)留一(yi)排(pai)氣(qi)(qi)孔,以(yi)使送電(dian)(dian)過程中(zhong)(zhong)爐(lu)(lu)(lu)(lu)(lu)芯內(nei)(nei)(nei)的(de)(de)煙氣(qi)(qi)能順利排(pai)出。使用(yong)(yong)耐(nai)火(huo)磚做(zuo)側(ce)(ce)墻(qiang)(qiang)(qiang),保(bao)溫效(xiao)果(guo)好(hao)(hao),使用(yong)(yong)壽命也稍長,但造(zao)價較(jiao)高(gao)(gao)(gao)。   活(huo)動(dong)(dong)(dong)式(shi)側(ce)(ce)墻(qiang)(qiang)(qiang)是由水(shui)(shui)(shui)(shui)泥、粘土(tu)、耐(nai)火(huo)磚碎塊等按一(yi)定(ding)比例配制而(er)成(cheng)(cheng)(cheng),墻(qiang)(qiang)(qiang)上(shang)(shang)留有排(pai)氣(qi)(qi)孔。使用(yong)(yong)時(shi)將活(huo)動(dong)(dong)(dong)側(ce)(ce)墻(qiang)(qiang)(qiang)吊放在(zai)爐(lu)(lu)(lu)(lu)(lu)兩(liang)(liang)側(ce)(ce)、由槽(cao)鋼做(zuo)成(cheng)(cheng)(cheng)的(de)(de)柱子(zi)間(jian)。活(huo)動(dong)(dong)(dong)式(shi)側(ce)(ce)墻(qiang)(qiang)(qiang)的(de)(de)優(you)點(dian)是經濟(ji)、省(sheng)工,且冷(leng)卻(que)(que)(que)(que)(que)(que)爐(lu)(lu)(lu)(lu)(lu)子(zi)時(shi)方(fang)便。缺點(dian)是不耐(nai)機(ji)械(xie)沖(chong)擊和(he)熱(re)(re)沖(chong)擊,以(yi)及破(po)損(sun)不能修(xiu)補等。   此外,現(xian)在(zai)還出現(xian)了(le)下半部為(wei)(wei)固定(ding)式(shi),上(shang)(shang)半部為(wei)(wei)活(huo)動(dong)(dong)(dong)式(shi)的(de)(de)混合型側(ce)(ce)墻(qiang)(qiang)(qiang),兼顧了(le)兩(liang)(liang)者的(de)(de)優(you)點(dian),使用(yong)(yong)效(xiao)果(guo)比較(jiao)理(li)想。槽(cao)鋼(或鑄鐵支架(jia))主要(yao)起(qi)固定(ding)側(ce)(ce)墻(qiang)(qiang)(qiang)的(de)(de)作(zuo)(zuo)用(yong)(yong)。通電(dian)(dian)爐(lu)(lu)(lu)(lu)(lu)芯由被加(jia)熱(re)(re)的(de)(de)產(chan)品和(he)中(zhong)(zhong)間(jian)填充電(dian)(dian)阻料組(zu)成(cheng)(cheng)(cheng)。通電(dian)(dian)后爐(lu)(lu)(lu)(lu)(lu)體(ti)有一(yi)定(ding)的(de)(de)熱(re)(re)脹力(li)。
