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)體框架采(cai)用(yong)(yong)槽鋼(gang)和角鋼(gang)焊接(jie)制作,外殼側板采(cai)用(yong)(yong)Q235鋼(gang)板焊接(jie),結構牢固可(ke)靠,整體強度好,不易(yi)變形(xing),外表平整光潔。爐(lu)體所有(you)焊接(jie)處進(jin)行打磨(mo)處理(li),并用(yong)(yong)鐵膩子刮平、噴涂熱防銹漆(qi)后,按照用(yong)(yong)戶提(ti)供的(de)色標進(jin)行油漆(qi)涂裝。
爐襯為(wei)全纖維結構,采用(yong)優(you)質耐高(gao)溫高(gao)鋁(lv)耐火纖維構筑,采用(yong)標準的錨固(gu)件及(ji)科(ke)學合理(li)的鑲裝方法。纖維折疊塊鑲裝前進行(xing)再次預壓縮(suo)處理(li)(壓縮(suo)容重≥230Kg/m3),用(yong)錨固(gu)件固(gu)定在殼體上,保(bao)溫材料安裝厚度≮300mm。
爐(lu)底采(cai)(cai)用(yong)(yong)重(zhong)質(zhi)高(gao)鋁(lv)耐火(huo)(huo)(huo)磚(zhuan)、輕(qing)質(zhi)耐火(huo)(huo)(huo)磚(zhuan)、保溫磚(zhuan)等(deng)制(zhi)(zhi)作(zuo)(zuo)成復合型襯(chen)(chen)(chen)(chen)體(ti)(ti),襯(chen)(chen)(chen)(chen)體(ti)(ti)上(shang)砌筑(zhu)有加(jia)熱(re)(re)(re)元件(jian)安裝槽(cao)形(xing)溝道(dao),易碰撞(zhuang)部位和承重(zhong)部位采(cai)(cai)用(yong)(yong)重(zhong)質(zhi)高(gao)鋁(lv)耐火(huo)(huo)(huo)磚(zhuan)砌筑(zhu)(砌筑(zhu)時泥漿內加(jia)入粘結劑調(diao)和),增(zeng)強爐(lu)襯(chen)(chen)(chen)(chen)結構強度。在制(zhi)(zhi)作(zuo)(zuo)時留有膨脹縫,防(fang)止(zhi)襯(chen)(chen)(chen)(chen)體(ti)(ti)在受熱(re)(re)(re)后(hou)膨脹將襯(chen)(chen)(chen)(chen)體(ti)(ti)損壞。鋪設爐(lu)底板,材質(zhi)為Ni7N,供(gong)擱置工(gong)(gong)件(jian)之用(yong)(yong),采(cai)(cai)用(yong)(yong)新型的搭扣制(zhi)(zhi)作(zuo)(zuo)形(xing)式,防(fang)止(zhi)工(gong)(gong)件(jian)氧化皮落到加(jia)熱(re)(re)(re)元件(jian)上(shang)而形(xing)成短(duan)路,耐熱(re)(re)(re)鋼(gang)爐(lu)底板分塊(kuai)制(zhi)(zhi)作(zuo)(zuo),減少高(gao)溫下變形(xing)和開(kai)裂。本(ben)爐(lu)型設計工(gong)(gong)作(zuo)(zuo)臺板。
