真(zhen)(zhen)(zhen)空(kong)(kong)(kong)甩(shuai)(shuai)帶(dai)爐(lu)用(yong)法(fa)介紹 　　真(zhen)(zhen)(zhen)空(kong)(kong)(kong)甩(shuai)(shuai)帶(dai)爐(lu)由真(zhen)(zhen)(zhen)空(kong)(kong)(kong)室、甩(shuai)(shuai)帶(dai)裝置(zhi)、坩堝(guo)自動升降裝置(zhi)、氣(qi)路系(xi)統、機殼(ke)和(he)熔(rong)(rong)煉(lian)(lian)電源等組成。該設備具(ju)有(you)(you)科技含量高(gao)、操(cao)作簡單，熔(rong)(rong)煉(lian)(lian)時間(jian)短、節能(neng)***等特(te)點(dian)。產品各(ge)項指標達(da)到或超過同類(lei)產品的(de)(de)(de)(de)性(xing)能(neng)。 　　真(zhen)(zhen)(zhen)空(kong)(kong)(kong)甩(shuai)(shuai)帶(dai)爐(lu)也叫真(zhen)(zhen)(zhen)空(kong)(kong)(kong)速凝爐(lu)，主要(yao)用(yong)于各(ge)種稀土永磁(ci)材(cai)料(liao)(liao)的(de)(de)(de)(de)熔(rong)(rong)煉(lian)(lian),合金的(de)(de)(de)(de)冶煉(lian)(lian)。是自主開發制造的(de)(de)(de)(de)一(yi)種集(ji)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)熔(rong)(rong)煉(lian)(lian)、自動噴鑄、冷(leng)凝器(qi)、機電于一(yi)體的(de)(de)(de)(de)精密設備。應(ying)用(yong)于對(dui)稀有(you)(you)金屬釹鐵硼(0.2—0.3mm厚)的(de)(de)(de)(de)熔(rong)(rong)煉(lian)(lian)和(he)甩(shuai)(shuai)帶(dai)成型。 　　爐(lu)子的(de)(de)(de)(de)加熱(re)(re)(re)(re)(re)與隔(ge)熱(re)(re)(re)(re)(re)襯料(liao)(liao)是在真(zhen)(zhen)(zhen)空(kong)(kong)(kong)與高(gao)溫(wen)下(xia)工(gong)作的(de)(de)(de)(de)，因而(er)對(dui)這(zhe)些(xie)材(cai)料(liao)(liao)提出了(le)耐(nai)高(gao)溫(wen)，蒸汽壓低，輻射(she)效果好，導熱(re)(re)(re)(re)(re)系(xi)數小等要(yao)求。對(dui)抗(kang)氧(yang)化性(xing)能(neng)要(yao)求不(bu)高(gao)。所以，真(zhen)(zhen)(zhen)空(kong)(kong)(kong)甩(shuai)(shuai)帶(dai)爐(lu)廣泛地采用(yong)了(le)鉭、鎢(wu)、鉬和(he)石墨等作加熱(re)(re)(re)(re)(re)與隔(ge)熱(re)(re)(re)(re)(re)構(gou)料(liao)(liao)。這(zhe)些(xie)材(cai)料(liao)(liao)在大氣(qi)狀態下(xia)極易氧(yang)化，因此，常規(gui)熱(re)(re)(re)(re)(re)處(chu)理爐(lu)是不(bu)能(neng)采用(yong)這(zhe)些(xie)加熱(re)(re)(re)(re)(re)與隔(ge)熱(re)(re)(re)(re)(re)材(cai)料(liao)(liao)。 　　真(zhen)(zhen)(zhen)空(kong)(kong)(kong)甩(shuai)(shuai)帶(dai)爐(lu)的(de)(de)(de)(de)爐(lu)殼(ke)、爐(lu)蓋、電熱(re)(re)(re)(re)(re)元件，分別處(chu)置(zhi)(水冷(leng)電極)、中(zhong)間(jian)真(zhen)(zhen)(zhen)空(kong)(kong)(kong)隔(ge)熱(re)(re)(re)(re)(re)門等部件，均在真(zhen)(zhen)(zhen)空(kong)(kong)(kong)、受熱(re)(re)(re)(re)(re)狀態下(xia)工(gong)作。在這(zhe)種極為不(bu)利(li)的(de)(de)(de)(de)條件下(xia)工(gong)作，必須保證各(ge)部件的(de)(de)(de)(de)結構(gou)不(bu)變(bian)形(xing)、不(bu)損壞，真(zhen)(zhen)(zhen)空(kong)(kong)(kong)密封圈不(bu)過熱(re)(re)(re)(re)(re)、不(bu)燒毀。因此，各(ge)部件應(ying)該根據不(bu)同的(de)(de)(de)(de)情況設置(zhi)水冷(leng)裝置(zhi)，以保證真(zhen)(zhen)(zhen)空(kong)(kong)(kong)熱(re)(re)(re)(re)(re)處(chu)理爐(lu)能(neng)夠正常運行并有(you)(you)足夠的(de)(de)(de)(de)使用(yong)壽命。
