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)(yong)(yong)槽鋼和(he)角鋼焊接制(zhi)作,外(wai)(wai)殼(ke)側板(ban)采用(yong)(yong)(yong)Q235鋼板(ban)焊接,結(jie)構牢(lao)固(gu)可靠(kao),整體強度好,不(bu)易變(bian)形(xing),外(wai)(wai)表平整光潔。爐體所(suo)有焊接處(chu)進行(xing)打(da)磨處(chu)理,并用(yong)(yong)(yong)鐵(tie)膩子刮平、噴涂熱防(fang)銹(xiu)漆后,按照用(yong)(yong)(yong)戶提供的(de)色標進行(xing)油漆涂裝。
爐襯(chen)為(wei)全纖(xian)(xian)維(wei)結構,采用(yong)(yong)優質耐高溫高鋁耐火纖(xian)(xian)維(wei)構筑,采用(yong)(yong)標準的錨(mao)固(gu)件及科學(xue)合(he)理(li)的鑲(xiang)裝方(fang)法。纖(xian)(xian)維(wei)折疊塊鑲(xiang)裝前進(jin)行(xing)再次預壓(ya)縮處理(li)(壓(ya)縮容重≥230Kg/m3),用(yong)(yong)錨(mao)固(gu)件固(gu)定在殼體上,保溫材料安裝厚度(du)≮300mm。
爐底(di)采用(yong)(yong)重(zhong)(zhong)質(zhi)高鋁(lv)耐(nai)火(huo)磚(zhuan)、輕(qing)質(zhi)耐(nai)火(huo)磚(zhuan)、保溫磚(zhuan)等(deng)制(zhi)作(zuo)成(cheng)復合型襯(chen)體,襯(chen)體上砌(qi)筑有加(jia)熱(re)(re)元(yuan)件安裝槽形(xing)溝道,易碰撞部(bu)位(wei)和承重(zhong)(zhong)部(bu)位(wei)采用(yong)(yong)重(zhong)(zhong)質(zhi)高鋁(lv)耐(nai)火(huo)磚(zhuan)砌(qi)筑(砌(qi)筑時(shi)泥漿內(nei)加(jia)入粘結(jie)劑調(diao)和),增(zeng)強爐襯(chen)結(jie)構強度(du)。在制(zhi)作(zuo)時(shi)留(liu)有膨脹(zhang)縫,防止襯(chen)體在受熱(re)(re)后膨脹(zhang)將襯(chen)體損壞(huai)。鋪(pu)設(she)爐底(di)板(ban),材質(zhi)為(wei)Ni7N,供(gong)擱置工件之用(yong)(yong),采用(yong)(yong)新型的(de)搭扣(kou)制(zhi)作(zuo)形(xing)式,防止工件氧(yang)化皮落到加(jia)熱(re)(re)元(yuan)件上而形(xing)成(cheng)短路(lu),耐(nai)熱(re)(re)鋼(gang)爐底(di)板(ban)分塊制(zhi)作(zuo),減少高溫下變形(xing)和開(kai)裂。本爐型設(she)計工作(zuo)臺板(ban)。
