保溫爐是一臺容(rong)量可達600公(gong)斤的(de)臥式有鐵芯(xin)工(gong)頻感應電(dian)(dian)爐,為(wei)了便于控制爐內熔融(rong)金屬的(de)溫(wen)度,可以采(cai)用(yong)(yong)調壓(ya)變壓(ya)器進行保溫(wen),但這種舊(jiu)式設(she)(she)備操(cao)作麻煩,二來消耗電(dian)(dian)力多(duo),設(she)(she)備占用(yong)(yong)面(mian)積也(ye)大,采(cai)用(yong)(yong)可控硅(gui)交流調壓(ya)器,操(cao)作簡單便利,而且能節約(yue)用(yong)(yong)電(dian)(dian),一臺保溫(wen)爐比用(yong)(yong)調壓(ya)變壓(ya)器每晝(zhou)夜可以節省300度電(dian)(dian),又能為(wei)生產自動(dong)化創(chuang)造(zao)了條(tiao)件。
另外,由(you)于(yu)升(sheng)液(ye)(ye)管的(de)(de)工(gong)作(zuo)(zuo)條件惡劣,鑄(zhu)(zhu)(zhu)造科技工(gong)作(zuo)(zuo)者(zhe)正(zheng)在(zai)(zai)尋求更好的(de)(de)材(cai)料和合理的(de)(de)措施(shi)以提(ti)高其壽(shou)命(ming)(ming)。現有(you)資料表明(ming):采(cai)用(yong)含磷2.7%的(de)(de)鑄(zhu)(zhu)(zhu)鐵、含銅6.5%的(de)(de)鑄(zhu)(zhu)(zhu)鐵、高錳鑄(zhu)(zhu)(zhu)鐵或用(yong)具有(you)D型石墨(mo)的(de)(de)珠光體(ti)基體(ti)的(de)(de)孕育(yu)鑄(zhu)(zhu)(zhu)鐵鑄(zhu)(zhu)(zhu)造升(sheng)液(ye)(ye)管,其壽(shou)命(ming)(ming)可(ke)能延長,可(ke)用(yong)120h以上(shang);有(you)的(de)(de)采(cai)用(yong)普通鑄(zhu)(zhu)(zhu)鐵管進行(xing)表面滲硫處理,在(zai)(zai)鋁液(ye)(ye)中的(de)(de)壽(shou)命(ming)(ming)約(yue)可(ke)提(ti)高3倍;有(you)的(de)(de)在(zai)(zai)鑄(zhu)(zhu)(zhu)鐵管表面噴(pen)鍍一層(ceng)三氧(yang)(yang)化(hua)(hua)二鋁、氧(yang)(yang)化(hua)(hua)鋯或氧(yang)(yang)化(hua)(hua)鉻等(deng)材(cai)料,升(sheng)液(ye)(ye)管在(zai)(zai)鋁液(ye)(ye)中的(de)(de)壽(shou)命(ming)(ming)可(ke)達700h;有(you)的(de)(de)試用(yong)氮化(hua)(hua)硅、碳化(hua)(hua)硅或氧(yang)(yang)化(hua)(hua)硼(peng)等(deng)耐熱(re)陶(tao)瓷(ci)作(zuo)(zuo)升(sheng)液(ye)(ye)管,雖然(ran)成本高,但在(zai)(zai)鋁液(ye)(ye)中可(ke)用(yong)半年以上(shang);還有(you)用(yong)石棉耐熱(re)硅酸鹽(yan)作(zuo)(zuo)升(sheng)液(ye)(ye)管,在(zai)(zai)三班連續作(zuo)(zuo)業的(de)(de)情(qing)況下,可(ke)使用(yong)4~5個(ge)月,效果良(liang)好。
