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(ti)(ti)框架采(cai)用(yong)槽鋼(gang)和角鋼(gang)焊接(jie)制作,外殼側(ce)板(ban)采(cai)用(yong)Q235鋼(gang)板(ban)焊接(jie),結構牢固可(ke)靠(kao),整(zheng)體(ti)(ti)強度好,不(bu)易(yi)變形,外表(biao)平(ping)整(zheng)光潔(jie)。爐(lu)體(ti)(ti)所有(you)焊接(jie)處進行打磨處理,并用(yong)鐵膩子刮平(ping)、噴(pen)涂(tu)熱防(fang)銹漆后,按照用(yong)戶提供(gong)的色標進行油(you)漆涂(tu)裝。
爐襯為全纖維(wei)(wei)結構,采(cai)用優質(zhi)耐(nai)高溫(wen)高鋁耐(nai)火纖維(wei)(wei)構筑,采(cai)用標準的錨固件(jian)及(ji)科學合理的鑲裝(zhuang)方法。纖維(wei)(wei)折(zhe)疊(die)塊鑲裝(zhuang)前(qian)進行再(zai)次預壓縮(suo)處理(壓縮(suo)容重(zhong)≥230Kg/m3),用錨固件(jian)固定在(zai)殼體上,保溫(wen)材料安裝(zhuang)厚度≮300mm。
爐(lu)底(di)采(cai)(cai)用(yong)重質(zhi)高(gao)鋁耐火磚(zhuan)(zhuan)(zhuan)(zhuan)、輕(qing)質(zhi)耐火磚(zhuan)(zhuan)(zhuan)(zhuan)、保(bao)溫(wen)磚(zhuan)(zhuan)(zhuan)(zhuan)等制(zhi)作(zuo)成復(fu)合型(xing)襯(chen)(chen)體(ti),襯(chen)(chen)體(ti)上砌(qi)筑(zhu)(zhu)有(you)加熱元(yuan)件(jian)安裝槽形溝道,易碰撞部位(wei)(wei)和(he)承重部位(wei)(wei)采(cai)(cai)用(yong)重質(zhi)高(gao)鋁耐火磚(zhuan)(zhuan)(zhuan)(zhuan)砌(qi)筑(zhu)(zhu)(砌(qi)筑(zhu)(zhu)時泥(ni)漿內加入粘(zhan)結(jie)劑調和(he)),增強爐(lu)襯(chen)(chen)結(jie)構強度。在(zai)制(zhi)作(zuo)時留有(you)膨脹縫(feng),防止(zhi)襯(chen)(chen)體(ti)在(zai)受熱后膨脹將襯(chen)(chen)體(ti)損壞(huai)。鋪(pu)設爐(lu)底(di)板(ban),材質(zhi)為Ni7N,供擱置工(gong)(gong)(gong)件(jian)之用(yong),采(cai)(cai)用(yong)新(xin)型(xing)的搭扣制(zhi)作(zuo)形式,防止(zhi)工(gong)(gong)(gong)件(jian)氧化皮落(luo)到(dao)加熱元(yuan)件(jian)上而形成短路(lu),耐熱鋼爐(lu)底(di)板(ban)分塊(kuai)制(zhi)作(zuo),減少高(gao)溫(wen)下變形和(he)開裂。本(ben)爐(lu)型(xing)設計工(gong)(gong)(gong)作(zuo)臺板(ban)。
