　　1.選用(yong)(yong)(yong)(yong)發熱部(bu)紅(hong)熱均勻(yun)(yun)性好的(de)(de)(de)(de)(de)石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)。棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)紅(hong)熱均勻(yun)(yun)性差會(hui)影響真(zhen)(zhen)空(kong)(kong)燒(shao)結(jie)爐爐溫(wen)(wen)均勻(yun)(yun)及縮短(duan)棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)使(shi)用(yong)(yong)(yong)(yong)壽(shou)命。在(zai)使(shi)用(yong)(yong)(yong)(yong)過(guo)程中，棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)紅(hong)熱均勻(yun)(yun)性會(hui)逐漸變差，嚴(yan)重(zhong)時(shi)(shi)(shi)造(zao)成(cheng)斷棒(bang)(bang)(bang)(bang)(bang)(bang)。 　　2.石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)隨著(zhu)使(shi)用(yong)(yong)(yong)(yong)溫(wen)(wen)度(du)(du)(du)越高壽(shou)命為越短(duan)，尤其在(zai)棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)溫(wen)(wen)度(du)(du)(du)超過(guo)1500°C以后，氧(yang)化(hua)速度(du)(du)(du)加(jia)(jia)快，壽(shou)命縮短(duan)，使(shi)用(yong)(yong)(yong)(yong)中注意盡(jin)量(liang)不(bu)要讓石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)表(biao)(biao)(biao)面(mian)溫(wen)(wen)度(du)(du)(du)過(guo)高。 　　3.石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)在(zai)空(kong)(kong)氣中被加(jia)(jia)熱后，表(biao)(biao)(biao)面(mian)形成(cheng)致(zhi)密(mi)的(de)(de)(de)(de)(de)氧(yang)化(hua)硅(gui)膜，變成(cheng)抗氧(yang)化(hua)的(de)(de)(de)(de)(de)保(bao)(bao)護膜，起到延(yan)長(chang)(chang)壽(shou)命的(de)(de)(de)(de)(de)作(zuo)用(yong)(yong)(yong)(yong)。間(jian)歇使(shi)用(yong)(yong)(yong)(yong)，隨著(zhu)真(zhen)(zhen)空(kong)(kong)燒(shao)結(jie)爐爐溫(wen)(wen)度(du)(du)(du)的(de)(de)(de)(de)(de)升(sheng)降(jiang)變化(hua)，會(hui)導(dao)致(zhi)棒(bang)(bang)(bang)(bang)(bang)(bang)表(biao)(biao)(biao)面(mian)的(de)(de)(de)(de)(de)保(bao)(bao)護膜破裂，保(bao)(bao)護作(zuo)用(yong)(yong)(yong)(yong)減弱，加(jia)(jia)快棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)電(dian)阻(zu)值(zhi)(zhi)變大。 　　石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)功(gong)率的(de)(de)(de)(de)(de)調(diao)(diao)整(zheng)方(fang)式(shi)，真(zhen)(zhen)空(kong)(kong)燒(shao)結(jie)爐廠家(jia)建議通(tong)過(guo)調(diao)(diao)整(zheng)電(dian)壓的(de)(de)(de)(de)(de)方(fang)式(shi)來(lai)調(diao)(diao)整(zheng)功(gong)率。推薦石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)調(diao)(diao)壓方(fang)式(shi)選擇可控硅(gui)調(diao)(diao)壓或調(diao)(diao)壓器(qi)調(diao)(diao)壓。一(yi)(yi)般(ban)(ban)不(bu)采用(yong)(yong)(yong)(yong)通(tong)過(guo)改(gai)變周波數的(de)(de)(de)(de)(de)調(diao)(diao)功(gong)器(qi)的(de)(de)(de)(de)(de)方(fang)式(shi)來(lai)調(diao)(diao)整(zheng)。 　　4.一(yi)(yi)般(ban)(ban)情況下，石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)表(biao)(biao)(biao)面(mian)負(fu)荷(he)密(mi)度(du)(du)(du)是由(you)真(zhen)(zhen)空(kong)(kong)燒(shao)結(jie)爐內溫(wen)(wen)度(du)(du)(du)和石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)表(biao)(biao)(biao)面(mian)溫(wen)(wen)度(du)(du)(du)的(de)(de)(de)(de)(de)關(guan)系求(qiu)得，建議使(shi)用(yong)(yong)(yong)(yong)石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)zui大表(biao)(biao)(biao)面(mian)負(fu)荷(he)密(mi)度(du)(du)(du)1/2-1/3數值(zhi)(zhi)的(de)(de)(de)(de)(de)功(gong)率。給石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)加(jia)(jia)的(de)(de)(de)(de)(de)電(dian)流量(liang)越大，石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)溫(wen)(wen)度(du)(du)(du)越高。建議使(shi)用(yong)(yong)(yong)(yong)盡(jin)量(liang)小的(de)(de)(de)(de)(de)表(biao)(biao)(biao)面(mian)負(fu)荷(he)密(mi)度(du)(du)(du)(功(gong)率)。 　　請注意石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)冷端記載的(de)(de)(de)(de)(de)數值(zhi)(zhi)為空(kong)(kong)氣中1050℃+-50℃范圍測(ce)得的(de)(de)(de)(de)(de)電(dian)流、電(dian)壓，與實(shi)際(ji)使(shi)用(yong)(yong)(yong)(yong)不(bu)一(yi)(yi)定相符。 　　5.連續使(shi)用(yong)(yong)(yong)(yong)石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)時(shi)(shi)(shi)，希望緩(huan)速增加(jia)(jia)電(dian)壓以維持長(chang)(chang)壽(shou)命。盡(jin)可能(neng)并聯。如(ru)果石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)阻(zu)值(zhi)(zhi)不(bu)同，串聯時(shi)(shi)(shi)電(dian)阻(zu)高的(de)(de)(de)(de)(de)石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)負(fu)荷(he)集中，導(dao)致(zhi)某一(yi)(yi)個石(shi)(shi)(shi)(shi)墨(mo)(mo)(mo)棒(bang)(bang)(bang)(bang)(bang)(bang)電(dian)阻(zu)快速增加(jia)(jia)，壽(shou)命變短(duan)。 　　同時(shi)(shi)(shi)需加(jia)(jia)強真(zhen)(zhen)空(kong)(kong)燒(shao)結(jie)爐的(de)(de)(de)(de)(de)電(dian)阻(zu)值(zhi)(zhi)的(de)(de)(de)(de)(de)配組，即同一(yi)(yi)組棒(bang)(bang)(bang)(bang)(bang)(bang)的(de)(de)(de)(de)(de)電(dian)阻(zu)值(zhi)(zhi)盡(jin)量(liang)接近。一(yi)(yi)般(ban)(ban)地，并聯時(shi)(shi)(shi)同組棒(bang)(bang)(bang)(bang)(bang)(bang)電(dian)阻(zu)值(zhi)(zhi)偏(pian)差在(zai)10%—15%以內，串聯時(shi)(shi)(shi)同組棒(bang)(bang)(bang)(bang)(bang)(bang)電(dian)阻(zu)值(zhi)(zhi)偏(pian)差在(zai)5%—10%以內。爐溫(wen)(wen)越高，要求(qiu)的(de)(de)(de)(de)(de)阻(zu)值(zhi)(zhi)偏(pian)差也應越小。
