真(zhen)空(kong)(kong)(kong)速凝爐(lu)(lu)各組成(cheng)(cheng)部(bu)(bu)分及工作原理
真(zhen)空(kong)(kong)(kong)速凝爐(lu)(lu)是(shi)(shi)利用(yong)真(zhen)空(kong)(kong)(kong)感(gan)(gan)應熔(rong)煉的(de)(de)方(fang)法(fa),在(zai)真(zhen)空(kong)(kong)(kong)或惰(duo)性氣(qi)(qi)(qi)體狀態(tai)下(xia)把合金原料熔(rong)煉并(bing)澆鑄在(zai)水(shui)(shui)冷(leng)輥上急(ji)速凝固(gu)后(hou)再在(zai)水(shui)(shui)冷(leng)盤(pan)上進(jin)行慢速降溫(wen)(wen)。把合金變成(cheng)(cheng)30°C左右且大小、薄(bo)(bo)厚均勻的(de)(de)合金薄(bo)(bo)片的(de)(de)一種(zhong)電(dian)熱(re)設(she)(she)(she)備。速凝爐(lu)(lu)已(yi)成(cheng)(cheng)為(wei)制造合金薄(bo)(bo)片的(de)(de)生(sheng)(sheng)產專用(yong)熔(rong)煉設(she)(she)(she)備在(zai)釹鐵硼磁材的(de)(de)生(sheng)(sheng)產中可有(you)效地(di)減少(shao)ɑ-Fe生(sheng)(sheng)成(cheng)(cheng)。
真(zhen)空(kong)(kong)(kong)速凝爐(lu)(lu)爐(lu)(lu)體為(wei)立式(shi)爐(lu)(lu)殼其內(nei)(nei)層(ceng)為(wei)不銹鋼制成(cheng)(cheng)的(de)(de)園(yuan)筒外層(ceng)為(wei)碳鋼。兩(liang)層(ceng)之間(jian)(jian)形(xing)成(cheng)(cheng)夾套,可以通(tong)冷(leng)卻(que)水(shui)(shui)將(jiang)傳到爐(lu)(lu)殼上的(de)(de)熱(re)量帶走,以使爐(lu)(lu)壁溫(wen)(wen)度(du)不超(chao)過60℃。中間(jian)(jian)開有(you)保護氣(qi)(qi)(qi)氛通(tong)氣(qi)(qi)(qi)口。熱(re)電(dian)偶測(ce)(ce)溫(wen)(wen)孔、抽氣(qi)(qi)(qi)孔及觀察孔。熱(re)電(dian)偶有(you)到溫(wen)(wen)自動(dong)退(tui)出裝(zhuang)置。紅外測(ce)(ce)溫(wen)(wen)觀察孔有(you)玻(bo)璃氣(qi)(qi)(qi)吹防霧裝(zhuang)置,操作人員使用(yong)的(de)(de)觀察孔設(she)(she)(she)有(you)擋板(ban)。
爐(lu)(lu)蓋(gai)(gai)有(you)內(nei)(nei)外封(feng)頭和法(fa)蘭組成(cheng)(cheng),中間(jian)(jian)水(shui)(shui)冷(leng)爐(lu)(lu)蓋(gai)(gai)吊在(zai)啟閉機構上,板(ban)動(dong)啟動(dong)機構上的(de)(de)手柄可以將(jiang)真(zhen)空(kong)(kong)(kong)速凝爐(lu)(lu)爐(lu)(lu)蓋(gai)(gai)升啟10-15mm,爐(lu)(lu)蓋(gai)(gai)上有(you)壓頭、壓力傳感(gan)(gan)器、排氣(qi)(qi)(qi)隔膜閥及爐(lu)(lu)蓋(gai)(gai)鎖緊裝(zhuang)置。
爐(lu)(lu)底(di)也是(shi)(shi)由內(nei)(nei)外封(feng)頭和法(fa)蘭組成(cheng)(cheng),中間(jian)(jian)水(shui)(shui)冷(leng),固(gu)定在(zai)爐(lu)(lu)體底(di)部(bu)(bu),有(you)電(dian)極引(yin)入,下(xia)壓頭進(jin)氣(qi)(qi)(qi)隔膜閥等組成(cheng)(cheng),并(bing)裝(zhuang)可調節高度(du)位(wei)移傳感(gan)(gan)器。
電(dian)爐(lu)(lu)真(zhen)空(kong)(kong)(kong)系(xi)統采用(yong)配電(dian)磁放氣(qi)(qi)(qi)閥及油擴散(san)泵。同(tong)時真(zhen)空(kong)(kong)(kong)速凝爐(lu)(lu)還設(she)(she)(she)有(you)冷(leng)阱及機組,測(ce)(ce)量為(wei)復(fu)合真(zhen)空(kong)(kong)(kong)計。
