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(ti)框架采用(yong)(yong)槽鋼和角鋼焊(han)接(jie)(jie)制(zhi)作,外(wai)(wai)殼側板采用(yong)(yong)Q235鋼板焊(han)接(jie)(jie),結(jie)構牢固可靠,整體(ti)強(qiang)度好,不易變形,外(wai)(wai)表平整光潔。爐體(ti)所(suo)有(you)焊(han)接(jie)(jie)處(chu)進行打磨處(chu)理(li),并用(yong)(yong)鐵膩子刮平、噴涂(tu)熱防銹(xiu)漆(qi)后,按(an)照用(yong)(yong)戶提供(gong)的色標進行油(you)漆(qi)涂(tu)裝。
爐(lu)襯為全纖(xian)維結構(gou),采用(yong)(yong)優質耐高溫(wen)高鋁耐火纖(xian)維構(gou)筑,采用(yong)(yong)標準的(de)錨(mao)固(gu)件及(ji)科(ke)學合(he)理的(de)鑲(xiang)(xiang)裝方法。纖(xian)維折(zhe)疊(die)塊鑲(xiang)(xiang)裝前進行再次預(yu)壓縮處理(壓縮容重≥230Kg/m3),用(yong)(yong)錨(mao)固(gu)件固(gu)定在(zai)殼體上,保溫(wen)材(cai)料安裝厚度≮300mm。
爐(lu)(lu)底采用(yong)重(zhong)質高(gao)(gao)鋁耐(nai)(nai)火磚(zhuan)、輕(qing)質耐(nai)(nai)火磚(zhuan)、保溫磚(zhuan)等制(zhi)作成(cheng)復合型襯體(ti),襯體(ti)上砌筑(zhu)有加熱(re)元件安裝槽(cao)形(xing)(xing)(xing)溝道,易碰撞部(bu)位和承重(zhong)部(bu)位采用(yong)重(zhong)質高(gao)(gao)鋁耐(nai)(nai)火磚(zhuan)砌筑(zhu)(砌筑(zhu)時(shi)(shi)泥漿內(nei)加入(ru)粘結劑調和),增強爐(lu)(lu)襯結構(gou)強度。在制(zhi)作時(shi)(shi)留有膨脹縫,防止襯體(ti)在受熱(re)后膨脹將(jiang)襯體(ti)損壞。鋪設爐(lu)(lu)底板,材質為(wei)Ni7N,供(gong)擱(ge)置工(gong)件之用(yong),采用(yong)新(xin)型的搭扣制(zhi)作形(xing)(xing)(xing)式,防止工(gong)件氧化(hua)皮(pi)落到加熱(re)元件上而形(xing)(xing)(xing)成(cheng)短路,耐(nai)(nai)熱(re)鋼爐(lu)(lu)底板分(fen)塊制(zhi)作,減少(shao)高(gao)(gao)溫下(xia)變形(xing)(xing)(xing)和開裂。本爐(lu)(lu)型設計工(gong)作臺(tai)板。
