真(zhen)空(kong)(kong)(kong)甩(shuai)(shuai)(shuai)帶爐(lu)(lu)(lu)用(yong)(yong)法介紹(shao)
真(zhen)空(kong)(kong)(kong)甩(shuai)(shuai)(shuai)帶爐(lu)(lu)(lu)由真(zhen)空(kong)(kong)(kong)室、甩(shuai)(shuai)(shuai)帶裝(zhuang)置、坩(gan)堝自(zi)動(dong)升降(jiang)裝(zhuang)置、氣路系統、機殼和(he)熔(rong)煉電(dian)(dian)源等(deng)(deng)組成。該設備具有科技含量高(gao)、操作(zuo)簡單,熔(rong)煉時間短(duan)、節能(neng)(neng)***等(deng)(deng)特點(dian)。產(chan)(chan)品各(ge)項(xiang)指標(biao)達到或超過(guo)同(tong)類產(chan)(chan)品的(de)性(xing)能(neng)(neng)。
真(zhen)空(kong)(kong)(kong)甩(shuai)(shuai)(shuai)帶爐(lu)(lu)(lu)也叫真(zhen)空(kong)(kong)(kong)速凝(ning)爐(lu)(lu)(lu),主要(yao)用(yong)(yong)于各(ge)種稀(xi)土(tu)永磁材(cai)(cai)料(liao)的(de)熔(rong)煉,合金(jin)的(de)冶(ye)煉。是自(zi)主開(kai)發制造的(de)一種集真(zhen)空(kong)(kong)(kong)熔(rong)煉、自(zi)動(dong)噴鑄、冷凝(ning)器、機電(dian)(dian)于一體(ti)的(de)精密設備。應(ying)用(yong)(yong)于對(dui)稀(xi)有金(jin)屬釹鐵硼(0.2—0.3mm厚(hou))的(de)熔(rong)煉和(he)甩(shuai)(shuai)(shuai)帶成型。
爐(lu)(lu)(lu)子的(de)加(jia)熱(re)(re)與(yu)隔(ge)熱(re)(re)襯料(liao)是在(zai)真(zhen)空(kong)(kong)(kong)與(yu)高(gao)溫下工(gong)(gong)作(zuo)的(de),因(yin)而(er)對(dui)這(zhe)(zhe)些材(cai)(cai)料(liao)提出(chu)了(le)耐高(gao)溫,蒸汽壓(ya)低,輻射效果好,導熱(re)(re)系數小等(deng)(deng)要(yao)求。對(dui)抗氧化(hua)性(xing)能(neng)(neng)要(yao)求不(bu)高(gao)。所以,真(zhen)空(kong)(kong)(kong)甩(shuai)(shuai)(shuai)帶爐(lu)(lu)(lu)廣泛(fan)地(di)采用(yong)(yong)了(le)鉭、鎢(wu)、鉬和(he)石(shi)墨等(deng)(deng)作(zuo)加(jia)熱(re)(re)與(yu)隔(ge)熱(re)(re)構料(liao)。這(zhe)(zhe)些材(cai)(cai)料(liao)在(zai)大氣狀(zhuang)態下極易氧化(hua),因(yin)此,常規熱(re)(re)處理爐(lu)(lu)(lu)是不(bu)能(neng)(neng)采用(yong)(yong)這(zhe)(zhe)些加(jia)熱(re)(re)與(yu)隔(ge)熱(re)(re)材(cai)(cai)料(liao)。
真(zhen)空(kong)(kong)(kong)甩(shuai)(shuai)(shuai)帶爐(lu)(lu)(lu)的(de)爐(lu)(lu)(lu)殼、爐(lu)(lu)(lu)蓋、電(dian)(dian)熱(re)(re)元件,分別處置(水冷電(dian)(dian)極)、中間真(zhen)空(kong)(kong)(kong)隔(ge)熱(re)(re)門等(deng)(deng)部件,均在(zai)真(zhen)空(kong)(kong)(kong)、受熱(re)(re)狀(zhuang)態下工(gong)(gong)作(zuo)。在(zai)這(zhe)(zhe)種極為不(bu)利的(de)條(tiao)件下工(gong)(gong)作(zuo),必須保證各(ge)部件的(de)結(jie)構不(bu)變形(xing)、不(bu)損壞,真(zhen)空(kong)(kong)(kong)密封圈不(bu)過(guo)熱(re)(re)、不(bu)燒毀。因(yin)此,各(ge)部件應(ying)該根據(ju)不(bu)同(tong)的(de)情況設置水冷裝(zhuang)置,以保證真(zhen)空(kong)(kong)(kong)熱(re)(re)處理爐(lu)(lu)(lu)能(neng)(neng)夠正常運行并有足夠的(de)使用(yong)(yong)壽命。
