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)(ti)框(kuang)架采用(yong)槽(cao)鋼和角鋼焊(han)(han)接(jie)制作,外(wai)殼側(ce)板采用(yong)Q235鋼板焊(han)(han)接(jie),結構牢固可靠,整體(ti)(ti)強度好,不易變(bian)形(xing),外(wai)表(biao)平整光潔(jie)。爐體(ti)(ti)所有焊(han)(han)接(jie)處進(jin)行打磨處理,并用(yong)鐵膩子刮平、噴涂熱防銹(xiu)漆后(hou),按(an)照用(yong)戶(hu)提供(gong)的色標進(jin)行油漆涂裝。
爐襯為全纖維(wei)結構,采(cai)(cai)用優(you)質耐(nai)高(gao)溫(wen)高(gao)鋁(lv)耐(nai)火纖維(wei)構筑,采(cai)(cai)用標準的錨固件及(ji)科學(xue)合理的鑲裝(zhuang)方法。纖維(wei)折疊塊鑲裝(zhuang)前進行再次(ci)預壓縮處理(壓縮容重≥230Kg/m3),用錨固件固定在殼體上,保溫(wen)材料安裝(zhuang)厚(hou)度≮300mm。
爐(lu)底采(cai)用(yong)重(zhong)質(zhi)(zhi)高鋁(lv)耐火磚(zhuan)(zhuan)、輕質(zhi)(zhi)耐火磚(zhuan)(zhuan)、保溫(wen)磚(zhuan)(zhuan)等制(zhi)(zhi)(zhi)作(zuo)成復合型襯(chen)(chen)(chen)體(ti)(ti),襯(chen)(chen)(chen)體(ti)(ti)上(shang)砌(qi)筑有加熱(re)元件安裝(zhuang)槽形(xing)(xing)溝道,易碰撞部位(wei)和(he)承重(zhong)部位(wei)采(cai)用(yong)重(zhong)質(zhi)(zhi)高鋁(lv)耐火磚(zhuan)(zhuan)砌(qi)筑(砌(qi)筑時泥漿內加入粘結劑調和(he)),增強(qiang)爐(lu)襯(chen)(chen)(chen)結構強(qiang)度。在(zai)制(zhi)(zhi)(zhi)作(zuo)時留有膨(peng)脹縫,防(fang)止(zhi)襯(chen)(chen)(chen)體(ti)(ti)在(zai)受熱(re)后膨(peng)脹將(jiang)襯(chen)(chen)(chen)體(ti)(ti)損(sun)壞。鋪設(she)爐(lu)底板,材質(zhi)(zhi)為Ni7N,供擱置(zhi)工(gong)件之用(yong),采(cai)用(yong)新型的搭扣制(zhi)(zhi)(zhi)作(zuo)形(xing)(xing)式(shi),防(fang)止(zhi)工(gong)件氧(yang)化(hua)皮落到加熱(re)元件上(shang)而形(xing)(xing)成短路,耐熱(re)鋼爐(lu)底板分塊制(zhi)(zhi)(zhi)作(zuo),減少(shao)高溫(wen)下變(bian)形(xing)(xing)和(he)開裂(lie)。本爐(lu)型設(she)計工(gong)作(zuo)臺板。
