真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)甩帶(dai)(dai)爐怎(zen)么用(yong)(yong)
真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)甩帶(dai)(dai)爐由(you)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)室、甩帶(dai)(dai)裝置(zhi)、坩堝自(zi)動(dong)升(sheng)降(jiang)裝置(zhi)、氣路系統(tong)、機殼(ke)和熔(rong)煉(lian)(lian)電(dian)(dian)源等組成(cheng)(cheng)。該設(she)備(bei)具有(you)科(ke)技含(han)量高、操作(zuo)簡單,熔(rong)煉(lian)(lian)時間短、節(jie)能(neng)***等特點。產品(pin)各項指(zhi)標達到或超過同類(lei)產品(pin)的(de)(de)性能(neng)。
真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)甩帶(dai)(dai)爐也叫真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)速凝(ning)爐,主要用(yong)(yong)于各種(zhong)(zhong)稀土(tu)永(yong)磁材(cai)料的(de)(de)熔(rong)煉(lian)(lian), 合金(jin)的(de)(de)冶煉(lian)(lian)。是自(zi)主開(kai)發制造的(de)(de)一種(zhong)(zhong)集真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)熔(rong)煉(lian)(lian)、自(zi)動(dong)噴鑄(zhu)、冷凝(ning)器(qi)、機電(dian)(dian)于一體的(de)(de)精密(mi)設(she)備(bei)。應用(yong)(yong)于對稀有(you)金(jin)屬釹鐵硼(0.2—0.3mm厚(hou))的(de)(de)熔(rong)煉(lian)(lian)和甩帶(dai)(dai)成(cheng)(cheng)型。
爐子(zi)的(de)(de)加熱(re)與(yu)(yu)隔熱(re)襯料是在真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)與(yu)(yu)高溫(wen)下工作(zuo)的(de)(de),因而對這些(xie)材(cai)料提出了耐(nai)高溫(wen),蒸汽壓低,輻(fu)射(she)效(xiao)果好,導熱(re)系數(shu)小等要求。對抗氧化(hua)性能(neng)要求不高。所以,真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)甩帶(dai)(dai)爐廣泛(fan)地采(cai)用(yong)(yong)了鉭(tan)、鎢、鉬(mu)和石墨等作(zuo)加熱(re)與(yu)(yu)隔熱(re)構料。這些(xie)材(cai)料在大氣狀(zhuang)態下極(ji)(ji)易氧化(hua),因此,常規熱(re)處理(li)爐是不能(neng)采(cai)用(yong)(yong)這些(xie)加熱(re)與(yu)(yu)隔熱(re)材(cai)料。
真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)甩帶(dai)(dai)爐的(de)(de)爐殼(ke)、爐蓋、電(dian)(dian)熱(re)元件(jian),分別處置(zhi)(水冷電(dian)(dian)極(ji)(ji))、中間真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)隔熱(re)門(men)等部件(jian),均在真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)、受熱(re)狀(zhuang)態下工作(zuo)。在這種(zhong)(zhong)極(ji)(ji)為(wei)不利的(de)(de)條(tiao)件(jian)下工作(zuo),必須(xu)保證(zheng)各部件(jian)的(de)(de)結構不變形、不損壞,真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)密(mi)封(feng)圈(quan)不過熱(re)、不燒毀。因此,各部件(jian)應該根據不同的(de)(de)情況設(she)置(zhi)水冷裝置(zhi),以保證(zheng)真(zhen)(zhen)(zhen)(zhen)空(kong)(kong)(kong)熱(re)處理(li)爐能(neng)夠(gou)正常運行(xing)并有(you)足(zu)夠(gou)的(de)(de)使用(yong)(yong)壽命(ming)。
