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。
爐體框架采用槽鋼(gang)和角鋼(gang)焊(han)接制作,外殼(ke)側板采用Q235鋼(gang)板焊(han)接,結構(gou)牢(lao)固可靠,整體強度(du)好,不易變形,外表平整光(guang)潔。爐體所有焊(han)接處進行(xing)打磨處理,并用鐵膩子刮平、噴涂熱防銹漆(qi)(qi)后,按(an)照用戶提供的色標進行(xing)油(you)漆(qi)(qi)涂裝(zhuang)。
爐襯(chen)為全纖(xian)(xian)維結構(gou),采(cai)用(yong)優質耐(nai)高(gao)溫(wen)高(gao)鋁(lv)耐(nai)火(huo)纖(xian)(xian)維構(gou)筑,采(cai)用(yong)標(biao)準的(de)(de)錨(mao)固(gu)件(jian)(jian)及科學合理的(de)(de)鑲(xiang)(xiang)裝(zhuang)(zhuang)方法。纖(xian)(xian)維折疊塊(kuai)鑲(xiang)(xiang)裝(zhuang)(zhuang)前(qian)進(jin)行(xing)再次預壓縮(suo)處(chu)理(壓縮(suo)容重≥230Kg/m3),用(yong)錨(mao)固(gu)件(jian)(jian)固(gu)定在殼體上(shang),保溫(wen)材料安裝(zhuang)(zhuang)厚度≮300mm。
爐底采(cai)用重(zhong)質(zhi)高(gao)(gao)鋁(lv)耐火磚(zhuan)、輕(qing)質(zhi)耐火磚(zhuan)、保(bao)溫(wen)磚(zhuan)等制(zhi)(zhi)作(zuo)成復(fu)合(he)型(xing)襯(chen)(chen)(chen)(chen)體(ti),襯(chen)(chen)(chen)(chen)體(ti)上(shang)砌筑(zhu)有(you)加(jia)熱(re)元(yuan)件(jian)安裝槽形(xing)溝(gou)道(dao),易碰撞部位(wei)和(he)(he)承重(zhong)部位(wei)采(cai)用重(zhong)質(zhi)高(gao)(gao)鋁(lv)耐火磚(zhuan)砌筑(zhu)(砌筑(zhu)時(shi)泥(ni)漿內加(jia)入粘結劑調和(he)(he)),增強爐襯(chen)(chen)(chen)(chen)結構強度。在制(zhi)(zhi)作(zuo)時(shi)留有(you)膨脹縫,防止襯(chen)(chen)(chen)(chen)體(ti)在受熱(re)后膨脹將(jiang)襯(chen)(chen)(chen)(chen)體(ti)損壞(huai)。鋪設爐底板(ban),材質(zhi)為Ni7N,供(gong)擱置工(gong)(gong)件(jian)之(zhi)用,采(cai)用新型(xing)的搭扣(kou)制(zhi)(zhi)作(zuo)形(xing)式,防止工(gong)(gong)件(jian)氧化皮落到加(jia)熱(re)元(yuan)件(jian)上(shang)而(er)形(xing)成短路,耐熱(re)鋼爐底板(ban)分(fen)塊制(zhi)(zhi)作(zuo),減少高(gao)(gao)溫(wen)下變形(xing)和(he)(he)開裂。本(ben)爐型(xing)設計工(gong)(gong)作(zuo)臺板(ban)。
