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(lu)體框架采(cai)(cai)用(yong)(yong)槽鋼(gang)(gang)和角(jiao)鋼(gang)(gang)焊(han)接(jie)制作(zuo),外殼側板采(cai)(cai)用(yong)(yong)Q235鋼(gang)(gang)板焊(han)接(jie),結構(gou)牢(lao)固可靠,整(zheng)體強度好(hao),不易變形,外表平整(zheng)光潔(jie)。爐(lu)體所有(you)焊(han)接(jie)處(chu)(chu)進行(xing)打磨處(chu)(chu)理(li),并用(yong)(yong)鐵膩子刮平、噴涂(tu)熱防銹漆后,按照(zhao)用(yong)(yong)戶提(ti)供(gong)的色標進行(xing)油漆涂(tu)裝(zhuang)。
爐襯為全(quan)纖(xian)維(wei)結(jie)構,采用優質耐(nai)高溫(wen)(wen)高鋁耐(nai)火纖(xian)維(wei)構筑,采用標準的錨固(gu)(gu)件及科(ke)學合理(li)的鑲裝方法。纖(xian)維(wei)折疊塊鑲裝前進(jin)行再次預壓縮(suo)處(chu)理(li)(壓縮(suo)容重≥230Kg/m3),用錨固(gu)(gu)件固(gu)(gu)定(ding)在殼體上(shang),保溫(wen)(wen)材料安裝厚度≮300mm。
爐(lu)底(di)(di)采用重(zhong)(zhong)(zhong)質(zhi)(zhi)高(gao)鋁耐火(huo)磚(zhuan)、輕質(zhi)(zhi)耐火(huo)磚(zhuan)、保溫磚(zhuan)等(deng)制(zhi)(zhi)作(zuo)成(cheng)復合型(xing)襯(chen)體,襯(chen)體上(shang)砌(qi)筑(zhu)(zhu)有加熱(re)元件(jian)安裝槽形(xing)溝道,易碰(peng)撞部位和承(cheng)重(zhong)(zhong)(zhong)部位采用重(zhong)(zhong)(zhong)質(zhi)(zhi)高(gao)鋁耐火(huo)磚(zhuan)砌(qi)筑(zhu)(zhu)(砌(qi)筑(zhu)(zhu)時泥漿(jiang)內加入粘結劑調和),增強爐(lu)襯(chen)結構強度。在制(zhi)(zhi)作(zuo)時留有膨(peng)脹縫,防(fang)止襯(chen)體在受(shou)熱(re)后(hou)膨(peng)脹將襯(chen)體損壞。鋪設爐(lu)底(di)(di)板,材質(zhi)(zhi)為(wei)Ni7N,供擱置(zhi)工件(jian)之用,采用新型(xing)的(de)搭(da)扣制(zhi)(zhi)作(zuo)形(xing)式(shi),防(fang)止工件(jian)氧化(hua)皮(pi)落到加熱(re)元件(jian)上(shang)而形(xing)成(cheng)短路(lu),耐熱(re)鋼爐(lu)底(di)(di)板分塊(kuai)制(zhi)(zhi)作(zuo),減少高(gao)溫下變形(xing)和開(kai)裂(lie)。本爐(lu)型(xing)設計工作(zuo)臺板。
