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)框架采用(yong)(yong)槽鋼(gang)和角鋼(gang)焊接制作(zuo),外殼側板采用(yong)(yong)Q235鋼(gang)板焊接,結(jie)構牢固可(ke)靠,整體(ti)(ti)強度好(hao),不(bu)易(yi)變形,外表(biao)平(ping)整光潔。爐體(ti)(ti)所(suo)有焊接處(chu)進(jin)行(xing)打磨(mo)處(chu)理(li),并用(yong)(yong)鐵膩子刮平(ping)、噴涂熱防(fang)銹漆(qi)(qi)后,按照用(yong)(yong)戶提供的色(se)標進(jin)行(xing)油漆(qi)(qi)涂裝。
爐襯為全纖(xian)維結構,采用(yong)(yong)優質耐高溫高鋁耐火(huo)纖(xian)維構筑(zhu),采用(yong)(yong)標(biao)準的錨固件(jian)及科學合理的鑲裝方法(fa)。纖(xian)維折(zhe)疊塊鑲裝前進行再次預壓縮(suo)處理(壓縮(suo)容重≥230Kg/m3),用(yong)(yong)錨固件(jian)固定在殼體上(shang),保溫材料安裝厚度≮300mm。
爐(lu)底(di)采(cai)用(yong)重(zhong)質(zhi)高(gao)鋁(lv)耐(nai)火(huo)(huo)磚(zhuan)(zhuan)、輕質(zhi)耐(nai)火(huo)(huo)磚(zhuan)(zhuan)、保溫(wen)磚(zhuan)(zhuan)等制(zhi)作(zuo)成(cheng)復合型襯(chen)體(ti),襯(chen)體(ti)上砌(qi)筑有加熱(re)元(yuan)件(jian)(jian)(jian)安裝(zhuang)槽形(xing)溝道(dao),易碰撞部位和(he)承(cheng)重(zhong)部位采(cai)用(yong)重(zhong)質(zhi)高(gao)鋁(lv)耐(nai)火(huo)(huo)磚(zhuan)(zhuan)砌(qi)筑(砌(qi)筑時(shi)泥漿內加入粘結(jie)劑(ji)調和(he)),增強爐(lu)襯(chen)結(jie)構(gou)強度。在(zai)制(zhi)作(zuo)時(shi)留有膨(peng)脹縫,防止襯(chen)體(ti)在(zai)受熱(re)后膨(peng)脹將襯(chen)體(ti)損(sun)壞。鋪(pu)設爐(lu)底(di)板(ban),材(cai)質(zhi)為Ni7N,供(gong)擱置工(gong)件(jian)(jian)(jian)之用(yong),采(cai)用(yong)新型的搭扣制(zhi)作(zuo)形(xing)式,防止工(gong)件(jian)(jian)(jian)氧化皮落到(dao)加熱(re)元(yuan)件(jian)(jian)(jian)上而形(xing)成(cheng)短(duan)路,耐(nai)熱(re)鋼爐(lu)底(di)板(ban)分塊制(zhi)作(zuo),減少(shao)高(gao)溫(wen)下變形(xing)和(he)開裂。本爐(lu)型設計工(gong)作(zuo)臺板(ban)。
