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(kuang)架(jia)采用(yong)(yong)槽鋼和角鋼焊(han)接制作,外(wai)(wai)殼側板采用(yong)(yong)Q235鋼板焊(han)接,結(jie)構牢固(gu)可靠,整(zheng)體(ti)強度好,不易變(bian)形,外(wai)(wai)表平整(zheng)光潔。爐(lu)體(ti)所有焊(han)接處進(jin)行打磨處理,并用(yong)(yong)鐵(tie)膩子刮(gua)平、噴涂熱(re)防銹(xiu)漆(qi)后,按照用(yong)(yong)戶提(ti)供的(de)色標進(jin)行油(you)漆(qi)涂裝(zhuang)。
爐襯為全纖(xian)維(wei)結構(gou),采(cai)用(yong)優(you)質耐高溫(wen)高鋁耐火纖(xian)維(wei)構(gou)筑,采(cai)用(yong)標準(zhun)的錨固件(jian)及科學合理(li)的鑲裝(zhuang)(zhuang)(zhuang)方法。纖(xian)維(wei)折疊塊鑲裝(zhuang)(zhuang)(zhuang)前進(jin)行再次預壓(ya)縮處理(li)(壓(ya)縮容重≥230Kg/m3),用(yong)錨固件(jian)固定在殼體(ti)上(shang),保溫(wen)材(cai)料安(an)裝(zhuang)(zhuang)(zhuang)厚度≮300mm。
爐底(di)采用(yong)重質高(gao)鋁(lv)耐火(huo)磚(zhuan)(zhuan)、輕(qing)質耐火(huo)磚(zhuan)(zhuan)、保溫磚(zhuan)(zhuan)等(deng)制(zhi)作(zuo)(zuo)成復合型襯(chen)體,襯(chen)體上砌(qi)(qi)筑有(you)加熱元件安裝(zhuang)槽形(xing)(xing)溝道,易碰撞(zhuang)部(bu)位(wei)和承(cheng)重部(bu)位(wei)采用(yong)重質高(gao)鋁(lv)耐火(huo)磚(zhuan)(zhuan)砌(qi)(qi)筑(砌(qi)(qi)筑時(shi)泥漿(jiang)內加入粘結(jie)(jie)劑(ji)調和),增強爐襯(chen)結(jie)(jie)構強度。在制(zhi)作(zuo)(zuo)時(shi)留有(you)膨脹(zhang)(zhang)縫,防止襯(chen)體在受熱后膨脹(zhang)(zhang)將襯(chen)體損壞(huai)。鋪設爐底(di)板(ban),材質為Ni7N,供擱置(zhi)工(gong)件之用(yong),采用(yong)新型的搭(da)扣制(zhi)作(zuo)(zuo)形(xing)(xing)式,防止工(gong)件氧化皮落到加熱元件上而形(xing)(xing)成短(duan)路(lu),耐熱鋼爐底(di)板(ban)分塊制(zhi)作(zuo)(zuo),減少(shao)高(gao)溫下變形(xing)(xing)和開裂。本爐型設計工(gong)作(zuo)(zuo)臺板(ban)。
