組件預熱爐主要由爐體、爐襯、爐底板、加熱元件、爐門及控制系統等部分組成。
爐體(ti)框(kuang)架采(cai)用(yong)槽鋼和角(jiao)鋼焊(han)接(jie)制作(zuo),外(wai)殼側(ce)板(ban)采(cai)用(yong)Q235鋼板(ban)焊(han)接(jie),結構牢固可(ke)靠,整(zheng)體(ti)強度好,不(bu)易變形,外(wai)表平整(zheng)光潔(jie)。爐體(ti)所有焊(han)接(jie)處進行(xing)打(da)磨(mo)處理,并用(yong)鐵(tie)膩子刮平、噴涂熱防銹漆后,按照用(yong)戶提供的(de)色標進行(xing)油漆涂裝(zhuang)。
爐襯為全(quan)纖維(wei)(wei)(wei)結(jie)構,采(cai)用(yong)(yong)優質耐高(gao)溫(wen)高(gao)鋁耐火(huo)纖維(wei)(wei)(wei)構筑(zhu),采(cai)用(yong)(yong)標準(zhun)的錨固件(jian)及科(ke)學(xue)合理(li)的鑲裝方法。纖維(wei)(wei)(wei)折(zhe)疊塊鑲裝前進(jin)行再次預(yu)壓縮處(chu)理(li)(壓縮容重≥230Kg/m3),用(yong)(yong)錨固件(jian)固定(ding)在殼體上(shang),保溫(wen)材料(liao)安裝厚度≮300mm。
爐底(di)(di)(di)采用(yong)重(zhong)質(zhi)高(gao)鋁耐(nai)火(huo)磚(zhuan)(zhuan)、輕(qing)質(zhi)耐(nai)火(huo)磚(zhuan)(zhuan)、保(bao)溫磚(zhuan)(zhuan)等制(zhi)(zhi)作(zuo)成(cheng)復(fu)合型襯體(ti),襯體(ti)上砌筑(zhu)有(you)加(jia)熱(re)元(yuan)件(jian)安裝槽形溝道(dao),易碰(peng)撞部(bu)位和承重(zhong)部(bu)位采用(yong)重(zhong)質(zhi)高(gao)鋁耐(nai)火(huo)磚(zhuan)(zhuan)砌筑(zhu)(砌筑(zhu)時(shi)(shi)泥漿內加(jia)入粘結劑(ji)調和),增強爐襯結構(gou)強度。在制(zhi)(zhi)作(zuo)時(shi)(shi)留有(you)膨脹縫(feng),防止(zhi)襯體(ti)在受(shou)熱(re)后膨脹將襯體(ti)損壞。鋪設(she)爐底(di)(di)(di)板(ban),材質(zhi)為Ni7N,供擱置工(gong)(gong)件(jian)之用(yong),采用(yong)新(xin)型的(de)搭(da)扣制(zhi)(zhi)作(zuo)形式,防止(zhi)工(gong)(gong)件(jian)氧化皮落到加(jia)熱(re)元(yuan)件(jian)上而形成(cheng)短路,耐(nai)熱(re)鋼(gang)爐底(di)(di)(di)板(ban)分(fen)塊制(zhi)(zhi)作(zuo),減少高(gao)溫下(xia)變形和開裂。本(ben)爐型設(she)計工(gong)(gong)作(zuo)臺(tai)板(ban)。
