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)(ti)框架采用槽鋼和角鋼焊接(jie)(jie)制作,外殼側板(ban)采用Q235鋼板(ban)焊接(jie)(jie),結構牢固可靠,整體(ti)(ti)強度好,不易變形,外表(biao)平(ping)整光(guang)潔。爐(lu)體(ti)(ti)所有焊接(jie)(jie)處進(jin)行打(da)磨處理,并用鐵膩子刮平(ping)、噴涂熱防銹漆后,按照(zhao)用戶提供的色標進(jin)行油漆涂裝。
爐襯為全纖(xian)維結(jie)構,采用優質耐(nai)(nai)高溫(wen)高鋁耐(nai)(nai)火(huo)纖(xian)維構筑,采用標準(zhun)的錨(mao)固件及(ji)科學合理的鑲裝方法(fa)。纖(xian)維折(zhe)疊塊鑲裝前進行再次預(yu)壓(ya)縮處(chu)理(壓(ya)縮容重≥230Kg/m3),用錨(mao)固件固定在殼體上(shang),保溫(wen)材料(liao)安裝厚度≮300mm。
爐(lu)底(di)采(cai)用(yong)(yong)(yong)重(zhong)質(zhi)高鋁耐火(huo)磚(zhuan)(zhuan)、輕(qing)質(zhi)耐火(huo)磚(zhuan)(zhuan)、保(bao)溫磚(zhuan)(zhuan)等制(zhi)作成(cheng)(cheng)復合型襯體(ti),襯體(ti)上砌筑(zhu)(zhu)有加熱(re)(re)元件(jian)(jian)(jian)安(an)裝(zhuang)槽形(xing)(xing)溝道,易碰(peng)撞部(bu)位和(he)承(cheng)重(zhong)部(bu)位采(cai)用(yong)(yong)(yong)重(zhong)質(zhi)高鋁耐火(huo)磚(zhuan)(zhuan)砌筑(zhu)(zhu)(砌筑(zhu)(zhu)時泥漿內(nei)加入(ru)粘結劑調和(he)),增強(qiang)爐(lu)襯結構強(qiang)度。在制(zhi)作時留有膨脹(zhang)縫,防(fang)止(zhi)襯體(ti)在受熱(re)(re)后(hou)膨脹(zhang)將襯體(ti)損壞。鋪設爐(lu)底(di)板,材質(zhi)為Ni7N,供擱置工件(jian)(jian)(jian)之用(yong)(yong)(yong),采(cai)用(yong)(yong)(yong)新(xin)型的搭(da)扣制(zhi)作形(xing)(xing)式(shi),防(fang)止(zhi)工件(jian)(jian)(jian)氧化皮落到加熱(re)(re)元件(jian)(jian)(jian)上而(er)形(xing)(xing)成(cheng)(cheng)短路,耐熱(re)(re)鋼爐(lu)底(di)板分塊制(zhi)作,減(jian)少高溫下變形(xing)(xing)和(he)開(kai)裂。本爐(lu)型設計(ji)工作臺板。
