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(jia)采用(yong)(yong)槽鋼和角鋼焊接(jie)制(zhi)作(zuo),外(wai)殼側(ce)板采用(yong)(yong)Q235鋼板焊接(jie),結構牢固可靠,整(zheng)體強度好,不易變形,外(wai)表平整(zheng)光潔。爐(lu)體所有焊接(jie)處(chu)進行打磨處(chu)理,并用(yong)(yong)鐵膩子刮平、噴涂(tu)熱(re)防銹漆后,按照用(yong)(yong)戶提供的色標進行油(you)漆涂(tu)裝。
爐襯(chen)為全纖(xian)(xian)維(wei)結(jie)構(gou),采用優(you)質耐高(gao)溫高(gao)鋁耐火纖(xian)(xian)維(wei)構(gou)筑(zhu),采用標準的錨固(gu)(gu)件及科學(xue)合(he)理的鑲裝方法。纖(xian)(xian)維(wei)折疊塊(kuai)鑲裝前(qian)進行再次(ci)預壓縮處理(壓縮容重≥230Kg/m3),用錨固(gu)(gu)件固(gu)(gu)定在(zai)殼體上,保溫材料安裝厚度≮300mm。
爐(lu)(lu)底(di)采(cai)(cai)用(yong)重(zhong)質(zhi)(zhi)高鋁(lv)耐火(huo)磚(zhuan)(zhuan)、輕質(zhi)(zhi)耐火(huo)磚(zhuan)(zhuan)、保溫磚(zhuan)(zhuan)等制(zhi)作(zuo)成復合型(xing)(xing)襯體,襯體上(shang)砌筑(zhu)有加(jia)熱(re)元(yuan)件(jian)(jian)(jian)安(an)裝槽(cao)形溝道,易(yi)碰撞部位(wei)和承(cheng)重(zhong)部位(wei)采(cai)(cai)用(yong)重(zhong)質(zhi)(zhi)高鋁(lv)耐火(huo)磚(zhuan)(zhuan)砌筑(zhu)(砌筑(zhu)時泥(ni)漿內加(jia)入粘結劑調(diao)和),增強爐(lu)(lu)襯結構強度。在制(zhi)作(zuo)時留有膨脹縫,防止襯體在受熱(re)后膨脹將(jiang)襯體損壞(huai)。鋪設爐(lu)(lu)底(di)板(ban),材質(zhi)(zhi)為Ni7N,供擱置工(gong)件(jian)(jian)(jian)之(zhi)用(yong),采(cai)(cai)用(yong)新(xin)型(xing)(xing)的搭扣(kou)制(zhi)作(zuo)形式,防止工(gong)件(jian)(jian)(jian)氧(yang)化(hua)皮(pi)落到加(jia)熱(re)元(yuan)件(jian)(jian)(jian)上(shang)而形成短路,耐熱(re)鋼爐(lu)(lu)底(di)板(ban)分塊制(zhi)作(zuo),減少高溫下變(bian)形和開裂。本爐(lu)(lu)型(xing)(xing)設計工(gong)作(zuo)臺板(ban)。
