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。
爐體框架采用(yong)槽鋼(gang)和角鋼(gang)焊接(jie)制作,外殼(ke)側板采用(yong)Q235鋼(gang)板焊接(jie),結構牢固(gu)可靠,整(zheng)(zheng)體強度好,不(bu)易變形,外表平(ping)整(zheng)(zheng)光潔。爐體所有焊接(jie)處進行(xing)打磨處理(li),并(bing)用(yong)鐵(tie)膩子刮(gua)平(ping)、噴(pen)涂(tu)熱防銹(xiu)漆后,按(an)照(zhao)用(yong)戶提供的色標(biao)進行(xing)油漆涂(tu)裝。
爐襯為全纖(xian)維結構,采用(yong)優質耐(nai)高溫(wen)高鋁耐(nai)火纖(xian)維構筑,采用(yong)標準的錨固件(jian)及科學合(he)理(li)的鑲裝方法。纖(xian)維折疊塊鑲裝前進行再(zai)次預壓(ya)縮處理(li)(壓(ya)縮容重≥230Kg/m3),用(yong)錨固件(jian)固定在殼體上,保溫(wen)材料(liao)安裝厚度≮300mm。
爐(lu)(lu)底(di)采(cai)用(yong)(yong)(yong)重質(zhi)(zhi)高(gao)鋁耐火磚、輕質(zhi)(zhi)耐火磚、保溫(wen)磚等制(zhi)作(zuo)成復合型(xing)襯體,襯體上砌(qi)筑(zhu)有(you)加(jia)熱(re)元件(jian)(jian)(jian)(jian)安裝槽形(xing)溝道,易碰撞部(bu)位和(he)承重部(bu)位采(cai)用(yong)(yong)(yong)重質(zhi)(zhi)高(gao)鋁耐火磚砌(qi)筑(zhu)(砌(qi)筑(zhu)時泥漿內加(jia)入(ru)粘結劑調和(he)),增(zeng)強爐(lu)(lu)襯結構強度。在制(zhi)作(zuo)時留有(you)膨脹(zhang)縫,防止襯體在受熱(re)后膨脹(zhang)將襯體損壞。鋪設爐(lu)(lu)底(di)板,材質(zhi)(zhi)為(wei)Ni7N,供擱(ge)置(zhi)工件(jian)(jian)(jian)(jian)之用(yong)(yong)(yong),采(cai)用(yong)(yong)(yong)新型(xing)的(de)搭(da)扣制(zhi)作(zuo)形(xing)式,防止工件(jian)(jian)(jian)(jian)氧化皮落到加(jia)熱(re)元件(jian)(jian)(jian)(jian)上而形(xing)成短路,耐熱(re)鋼爐(lu)(lu)底(di)板分塊制(zhi)作(zuo),減(jian)少高(gao)溫(wen)下變形(xing)和(he)開裂。本爐(lu)(lu)型(xing)設計工作(zuo)臺板。
