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(ti)框架采用(yong)(yong)槽鋼(gang)和角(jiao)鋼(gang)焊(han)接(jie)制(zhi)作,外殼側板采用(yong)(yong)Q235鋼(gang)板焊(han)接(jie),結構牢(lao)固可靠,整體(ti)強度好,不(bu)易(yi)變形,外表平(ping)整光潔(jie)。爐(lu)體(ti)所有(you)焊(han)接(jie)處(chu)(chu)進(jin)行(xing)(xing)打(da)磨處(chu)(chu)理(li),并用(yong)(yong)鐵膩子刮平(ping)、噴涂熱(re)防銹漆(qi)后,按照用(yong)(yong)戶提供的色標進(jin)行(xing)(xing)油漆(qi)涂裝。
爐襯為全(quan)纖維結構,采用優質耐高(gao)溫高(gao)鋁耐火纖維構筑(zhu),采用標(biao)準的錨固(gu)件及(ji)科(ke)學合理的鑲裝(zhuang)方法(fa)。纖維折疊塊鑲裝(zhuang)前進行再次預(yu)壓(ya)縮(suo)處理(壓(ya)縮(suo)容重≥230Kg/m3),用錨固(gu)件固(gu)定在殼體上,保(bao)溫材料安裝(zhuang)厚度(du)≮300mm。
爐(lu)底(di)(di)采用(yong)重(zhong)質高(gao)(gao)鋁耐火(huo)磚(zhuan)(zhuan)(zhuan)、輕質耐火(huo)磚(zhuan)(zhuan)(zhuan)、保溫磚(zhuan)(zhuan)(zhuan)等制作成(cheng)復合型襯(chen)體,襯(chen)體上砌筑有加熱(re)元件(jian)(jian)(jian)安(an)裝槽形(xing)(xing)溝(gou)道,易(yi)碰撞(zhuang)部位和(he)承重(zhong)部位采用(yong)重(zhong)質高(gao)(gao)鋁耐火(huo)磚(zhuan)(zhuan)(zhuan)砌筑(砌筑時泥漿內加入粘結(jie)劑(ji)調和(he)),增強(qiang)爐(lu)襯(chen)結(jie)構強(qiang)度。在制作時留有膨脹縫,防(fang)止襯(chen)體在受熱(re)后膨脹將襯(chen)體損壞。鋪設爐(lu)底(di)(di)板(ban),材質為Ni7N,供(gong)擱置工(gong)件(jian)(jian)(jian)之用(yong),采用(yong)新型的搭扣制作形(xing)(xing)式(shi),防(fang)止工(gong)件(jian)(jian)(jian)氧化皮(pi)落到加熱(re)元件(jian)(jian)(jian)上而形(xing)(xing)成(cheng)短路,耐熱(re)鋼爐(lu)底(di)(di)板(ban)分塊制作,減(jian)少高(gao)(gao)溫下變形(xing)(xing)和(he)開(kai)裂。本爐(lu)型設計(ji)工(gong)作臺(tai)板(ban)。
