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)框架采(cai)用槽鋼和角鋼焊接制(zhi)作(zuo)，外(wai)殼(ke)側板(ban)采(cai)用Q235鋼板(ban)焊接，結構牢固可靠，整體(ti)強(qiang)度好，不(bu)易變形(xing)，外(wai)表平整光潔。爐體(ti)所有焊接處進(jin)行(xing)打磨處理，并用鐵膩子刮平、噴涂熱(re)防銹(xiu)漆后，按照用戶提供的色(se)標進(jin)行(xing)油(you)漆涂裝。

爐襯為全纖(xian)維(wei)(wei)(wei)結構，采(cai)用(yong)(yong)優質耐高溫高鋁耐火纖(xian)維(wei)(wei)(wei)構筑，采(cai)用(yong)(yong)標(biao)準的錨(mao)固(gu)件及(ji)科學(xue)合理的鑲裝方法。纖(xian)維(wei)(wei)(wei)折疊塊鑲裝前進(jin)行(xing)再次(ci)預壓縮處理（壓縮容(rong)重≥230Kg/m3），用(yong)(yong)錨(mao)固(gu)件固(gu)定在(zai)殼體上(shang)，保溫材料安(an)裝厚度≮300mm。

爐底(di)采(cai)用(yong)(yong)(yong)重(zhong)(zhong)質(zhi)(zhi)高鋁(lv)耐火(huo)(huo)磚、輕質(zhi)(zhi)耐火(huo)(huo)磚、保溫磚等制(zhi)作(zuo)成(cheng)復合型襯(chen)體(ti)(ti)，襯(chen)體(ti)(ti)上砌(qi)筑(zhu)有(you)加熱(re)元(yuan)件安(an)裝槽(cao)形(xing)(xing)(xing)溝道(dao)，易碰(peng)撞部位和(he)(he)承(cheng)重(zhong)(zhong)部位采(cai)用(yong)(yong)(yong)重(zhong)(zhong)質(zhi)(zhi)高鋁(lv)耐火(huo)(huo)磚砌(qi)筑(zhu)(砌(qi)筑(zhu)時泥漿內加入粘結劑調和(he)(he))，增強(qiang)爐襯(chen)結構強(qiang)度。在(zai)制(zhi)作(zuo)時留有(you)膨(peng)脹縫，防止襯(chen)體(ti)(ti)在(zai)受熱(re)后膨(peng)脹將襯(chen)體(ti)(ti)損壞。鋪設爐底(di)板，材質(zhi)(zhi)為Ni7N，供(gong)擱置工件之用(yong)(yong)(yong)，采(cai)用(yong)(yong)(yong)新型的搭(da)扣制(zhi)作(zuo)形(xing)(xing)(xing)式，防止工件氧化皮(pi)落(luo)到加熱(re)元(yuan)件上而(er)形(xing)(xing)(xing)成(cheng)短(duan)路，耐熱(re)鋼爐底(di)板分塊制(zhi)作(zuo)，減少高溫下(xia)變(bian)形(xing)(xing)(xing)和(he)(he)開裂。本爐型設計工作(zuo)臺板。
