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(jia)采(cai)用(yong)(yong)槽鋼和角鋼焊接制(zhi)作,外殼側板采(cai)用(yong)(yong)Q235鋼板焊接,結構牢固可靠,整(zheng)體強(qiang)度好(hao),不易變形,外表平整(zheng)光潔。爐體所有(you)焊接處進行打磨處理,并(bing)用(yong)(yong)鐵膩子(zi)刮(gua)平、噴涂熱防銹漆后(hou),按(an)照用(yong)(yong)戶提(ti)供的色標進行油漆涂裝。
爐襯為全纖(xian)維結構,采用(yong)優質(zhi)耐高(gao)溫高(gao)鋁耐火纖(xian)維構筑,采用(yong)標準的(de)錨(mao)固件(jian)及科學合理(li)的(de)鑲裝(zhuang)方法。纖(xian)維折(zhe)疊塊鑲裝(zhuang)前(qian)進行再次(ci)預壓縮(suo)處理(li)(壓縮(suo)容重≥230Kg/m3),用(yong)錨(mao)固件(jian)固定在殼體上(shang),保(bao)溫材料安裝(zhuang)厚度≮300mm。
爐(lu)(lu)底(di)(di)采用(yong)(yong)(yong)重(zhong)(zhong)質(zhi)高鋁(lv)耐火磚(zhuan)、輕質(zhi)耐火磚(zhuan)、保溫磚(zhuan)等制作成(cheng)復合(he)型(xing)襯(chen)(chen)體(ti),襯(chen)(chen)體(ti)上砌(qi)(qi)筑(zhu)有加熱元(yuan)件安(an)裝槽(cao)形溝道,易(yi)碰撞部(bu)(bu)位(wei)和(he)承重(zhong)(zhong)部(bu)(bu)位(wei)采用(yong)(yong)(yong)重(zhong)(zhong)質(zhi)高鋁(lv)耐火磚(zhuan)砌(qi)(qi)筑(zhu)(砌(qi)(qi)筑(zhu)時泥漿(jiang)內加入(ru)粘結劑(ji)調和(he)),增強爐(lu)(lu)襯(chen)(chen)結構強度。在制作時留有膨脹縫,防止襯(chen)(chen)體(ti)在受熱后膨脹將襯(chen)(chen)體(ti)損壞(huai)。鋪設(she)爐(lu)(lu)底(di)(di)板(ban),材(cai)質(zhi)為Ni7N,供擱置工(gong)件之(zhi)用(yong)(yong)(yong),采用(yong)(yong)(yong)新型(xing)的搭扣制作形式,防止工(gong)件氧化皮落到加熱元(yuan)件上而形成(cheng)短路,耐熱鋼(gang)爐(lu)(lu)底(di)(di)板(ban)分塊制作,減少高溫下變形和(he)開裂。本爐(lu)(lu)型(xing)設(she)計工(gong)作臺板(ban)。
