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)體框架(jia)采(cai)用(yong)(yong)槽鋼和角鋼焊接制作(zuo),外殼側板采(cai)用(yong)(yong)Q235鋼板焊接,結(jie)構牢(lao)固可靠(kao),整體強度好,不易(yi)變形,外表(biao)平整光潔(jie)。爐(lu)體所有焊接處進行打磨處理,并用(yong)(yong)鐵膩子(zi)刮平、噴涂熱(re)防銹漆(qi)后,按照(zhao)用(yong)(yong)戶(hu)提供的色標進行油漆(qi)涂裝(zhuang)。
爐襯為全(quan)纖維結(jie)構,采用(yong)優質耐高溫(wen)高鋁耐火纖維構筑(zhu),采用(yong)標準(zhun)的(de)錨(mao)固(gu)(gu)件(jian)及科學合理(li)的(de)鑲裝方法。纖維折疊塊鑲裝前進(jin)行(xing)再次預壓縮處理(li)(壓縮容重(zhong)≥230Kg/m3),用(yong)錨(mao)固(gu)(gu)件(jian)固(gu)(gu)定在(zai)殼體上,保(bao)溫(wen)材(cai)料(liao)安裝厚(hou)度(du)≮300mm。
爐底采用(yong)重質高(gao)(gao)鋁耐(nai)火磚(zhuan)(zhuan)(zhuan)(zhuan)、輕(qing)質耐(nai)火磚(zhuan)(zhuan)(zhuan)(zhuan)、保溫磚(zhuan)(zhuan)(zhuan)(zhuan)等制作成(cheng)(cheng)復合型襯體(ti)(ti),襯體(ti)(ti)上(shang)砌筑有(you)加(jia)熱(re)元件(jian)(jian)安裝槽(cao)形(xing)溝道,易(yi)碰撞部位(wei)和承重部位(wei)采用(yong)重質高(gao)(gao)鋁耐(nai)火磚(zhuan)(zhuan)(zhuan)(zhuan)砌筑(砌筑時(shi)泥漿內加(jia)入粘(zhan)結(jie)劑(ji)調(diao)和),增(zeng)強(qiang)爐襯結(jie)構(gou)強(qiang)度。在(zai)制作時(shi)留有(you)膨脹縫,防(fang)止襯體(ti)(ti)在(zai)受熱(re)后(hou)膨脹將襯體(ti)(ti)損壞(huai)。鋪(pu)設爐底板(ban),材(cai)質為(wei)Ni7N,供擱置(zhi)工(gong)(gong)件(jian)(jian)之用(yong),采用(yong)新(xin)型的(de)搭(da)扣制作形(xing)式,防(fang)止工(gong)(gong)件(jian)(jian)氧(yang)化皮落(luo)到加(jia)熱(re)元件(jian)(jian)上(shang)而形(xing)成(cheng)(cheng)短(duan)路,耐(nai)熱(re)鋼爐底板(ban)分塊制作,減少高(gao)(gao)溫下變形(xing)和開(kai)裂。本爐型設計(ji)工(gong)(gong)作臺板(ban)。
