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(cai)用(yong)槽鋼和(he)角鋼焊接(jie)(jie)(jie)制作,外殼側板采(cai)用(yong)Q235鋼板焊接(jie)(jie)(jie),結構牢固可靠,整體強度好,不易變(bian)形,外表平整光潔。爐體所有(you)焊接(jie)(jie)(jie)處進行打磨(mo)處理(li),并用(yong)鐵膩子刮平、噴(pen)涂熱防銹漆(qi)后,按照用(yong)戶提供的色(se)標(biao)進行油(you)漆(qi)涂裝。
爐襯(chen)為(wei)全纖(xian)維(wei)(wei)結構,采用(yong)(yong)優質(zhi)耐高溫高鋁(lv)耐火纖(xian)維(wei)(wei)構筑,采用(yong)(yong)標準的錨固(gu)件(jian)及科學合理的鑲裝(zhuang)方法。纖(xian)維(wei)(wei)折疊塊鑲裝(zhuang)前進行再次預壓(ya)縮處理(壓(ya)縮容(rong)重≥230Kg/m3),用(yong)(yong)錨固(gu)件(jian)固(gu)定在殼體上,保(bao)溫材(cai)料安裝(zhuang)厚度≮300mm。
爐(lu)底采用(yong)重(zhong)質(zhi)高(gao)鋁耐(nai)火磚(zhuan)、輕(qing)質(zhi)耐(nai)火磚(zhuan)、保(bao)溫(wen)磚(zhuan)等制(zhi)作(zuo)成復合型(xing)襯(chen)體(ti)(ti),襯(chen)體(ti)(ti)上(shang)砌(qi)筑有(you)(you)加熱元件安裝槽形(xing)(xing)溝道(dao),易(yi)碰撞部(bu)位和承重(zhong)部(bu)位采用(yong)重(zhong)質(zhi)高(gao)鋁耐(nai)火磚(zhuan)砌(qi)筑(砌(qi)筑時泥漿內加入粘結劑調和),增(zeng)強爐(lu)襯(chen)結構(gou)強度(du)。在制(zhi)作(zuo)時留有(you)(you)膨脹縫(feng),防(fang)止(zhi)襯(chen)體(ti)(ti)在受熱后膨脹將襯(chen)體(ti)(ti)損壞(huai)。鋪設(she)爐(lu)底板(ban),材質(zhi)為Ni7N,供擱置工(gong)(gong)件之(zhi)用(yong),采用(yong)新(xin)型(xing)的搭扣制(zhi)作(zuo)形(xing)(xing)式,防(fang)止(zhi)工(gong)(gong)件氧(yang)化(hua)皮落到加熱元件上(shang)而形(xing)(xing)成短路,耐(nai)熱鋼爐(lu)底板(ban)分塊制(zhi)作(zuo),減少高(gao)溫(wen)下變形(xing)(xing)和開裂。本爐(lu)型(xing)設(she)計(ji)工(gong)(gong)作(zuo)臺板(ban)。
