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(cai)用(yong)槽鋼(gang)和角鋼(gang)焊(han)接制作,外(wai)殼側板采(cai)用(yong)Q235鋼(gang)板焊(han)接,結構牢固可(ke)靠,整體強度(du)好(hao),不易變形,外(wai)表(biao)平整光潔。爐體所有焊(han)接處進(jin)行打磨處理,并用(yong)鐵膩(ni)子刮(gua)平、噴(pen)涂(tu)熱(re)防銹漆后,按(an)照用(yong)戶提供(gong)的色標進(jin)行油漆涂(tu)裝(zhuang)。
爐(lu)襯為(wei)全纖(xian)(xian)維結構,采(cai)(cai)用(yong)優質耐高溫(wen)高鋁(lv)耐火纖(xian)(xian)維構筑,采(cai)(cai)用(yong)標準的錨固件及科學合理的鑲裝方法。纖(xian)(xian)維折疊塊鑲裝前進(jin)行再次預壓縮(suo)處理(壓縮(suo)容(rong)重(zhong)≥230Kg/m3),用(yong)錨固件固定在(zai)殼體上,保(bao)溫(wen)材(cai)料(liao)安裝厚度≮300mm。
爐底(di)采(cai)(cai)用(yong)重質(zhi)高(gao)鋁(lv)耐火(huo)磚、輕質(zhi)耐火(huo)磚、保溫(wen)磚等(deng)制(zhi)作成(cheng)復合型(xing)(xing)襯(chen)(chen)體(ti)(ti)(ti),襯(chen)(chen)體(ti)(ti)(ti)上砌(qi)筑有加(jia)(jia)熱(re)元(yuan)件(jian)(jian)安裝槽形溝道,易碰撞部(bu)(bu)位(wei)和承重部(bu)(bu)位(wei)采(cai)(cai)用(yong)重質(zhi)高(gao)鋁(lv)耐火(huo)磚砌(qi)筑(砌(qi)筑時泥漿內加(jia)(jia)入(ru)粘結(jie)劑調和),增強(qiang)爐襯(chen)(chen)結(jie)構強(qiang)度。在(zai)制(zhi)作時留有膨脹(zhang)縫,防止襯(chen)(chen)體(ti)(ti)(ti)在(zai)受熱(re)后膨脹(zhang)將(jiang)襯(chen)(chen)體(ti)(ti)(ti)損(sun)壞(huai)。鋪(pu)設爐底(di)板(ban)(ban)(ban),材質(zhi)為(wei)Ni7N,供擱置工件(jian)(jian)之用(yong),采(cai)(cai)用(yong)新型(xing)(xing)的(de)搭扣制(zhi)作形式,防止工件(jian)(jian)氧(yang)化皮落到加(jia)(jia)熱(re)元(yuan)件(jian)(jian)上而形成(cheng)短路,耐熱(re)鋼爐底(di)板(ban)(ban)(ban)分塊制(zhi)作,減少高(gao)溫(wen)下變形和開裂。本爐型(xing)(xing)設計(ji)工作臺板(ban)(ban)(ban)。
