  真空(kong)甩帶爐主(zhu)要可用于熔煉高(gao)熔點(dian)金(jin)屬

  真空甩帶爐主要用于熔煉高(gao)熔點金屬/合金,以(yi)及(ji)(ji)半導體材(cai)料(liao)、合金小(xiao)試(shi)樣、稀土材(cai)料(liao)的(de)提純,采用真空(kong)噴(pen)/吸(xi)鑄(zhu)法(fa)可(ke)制(zhi)備大塊非(fei)晶材(cai)料(liao),采用熔態(tai)單(dan)輥旋淬法(fa)可(ke)制(zhi)備條帶非(fei)晶材(cai)料(liao),或通過(guo)非(fei)晶態(tai)技(ji)術制(zhi)備釬料(liao)。由真空(kong)獲得及(ji)(ji)測量系統、單(dan)輥旋淬條帶制(zhi)備系統、電(dian)弧熔煉/真空(kong)吸(xi)鑄(zhu)系統及(ji)(ji)電(dian)控系統等(deng)組成。采用非(fei)自耗熔煉方式,電(dian)磁場對電(dian)弧的(de)約(yue)束而產生的(de)透(tou)底熔煉及(ji)(ji)拌勻作用,縮短(duan)了熔煉時間,提高(gao)了效(xiao)率。采用變(bian)頻調速,手動設定輥輪表(biao)面速度。

真空甩帶爐

  真空(kong)甩帶爐操作流程:

  1.記錄電(dian)表讀(du)數,開(kai)(kai)電(dian)源(yuan)總開(kai)(kai)關,開(kai)(kai)循環(huan)水(shui)(電(dian)源(yuan)開(kai)(kai)關和壓縮機開(kai)(kai)關);

  2.開(kai)機械泵后緩慢開(kai)啟旁抽閥;

  3.壓(ya)力(li)氣罐清洗(可(ke)選(xuan)步驟(zou)),壓(ya)力(li)氣罐充氣;

  4.打(da)開(kai)真空計,待腔體氣壓小于5Pa后關閉旁抽閥(fa),打(da)開(kai)預抽開(kai)關;

  5.當真(zhen)空甩帶(dai)爐左右(you)真(zhen)空計均(jun)顯示氣(qi)壓小(xiao)于5Pa后(hou)關閉真(zhen)空計,緩慢開(kai)啟(qi)插板閥,打開(kai)分子泵(beng)開(kai)關;

  6.***少5分鐘后(hou)再打開真(zhen)空(kong)計(ji)(ji)并確認分子(zi)泵滿速(su)運轉,到(dao)所(suo)需真(zhen)空(kong)度(du)后(hou)關閉真(zhen)空(kong)計(ji)(ji);

  7.關(guan)(guan)閉(bi)(bi)插板閥,關(guan)(guan)閉(bi)(bi)分子泵,打開(kai)氬氣(qi)瓶,輕旋腔(qiang)(qiang)體(ti)充(chong)氣(qi)閥,充(chong)***適當腔(qiang)(qiang)體(ti)氣(qi)壓后關(guan)(guan)閉(bi)(bi)腔(qiang)(qiang)體(ti)充(chong)氣(qi)閥和氬氣(qi)瓶開(kai)關(guan)(guan);

  8.依次打開變頻調(diao)速開關,調(diao)***所(suo)需銅輪旋轉頻率,打開腔體測(ce)溫開關,打開感應(ying)加熱電源開關,按(an)照(zhao)材料特征選(xuan)擇恒(heng)流(liu)或恒(heng)功(gong)率加熱模式(shi);

  9.啟(qi)動銅輪旋轉,達到轉速后(hou),手按(an)加熱(re)踏板(黑色),使材料(liao)加熱(re)融化,待融化到所需溫度,松開(kai)(kai)加熱(re)踏板,并按(an)吹氣(qi)開(kai)(kai)關噴甩條帶;

  10.依次關(guan)閉(bi)(bi)真(zhen)空甩帶(dai)爐銅輪旋(xuan)轉(zhuan)開(kai)關(guan),關(guan)閉(bi)(bi)感應加熱(re)電源開(kai)關(guan),關(guan)閉(bi)(bi)預抽開(kai)關(guan),打(da)開(kai)旁抽閥(fa)。擰松腔體旋(xuan)鈕后關(guan)閉(bi)(bi)旁抽閥(fa),對腔體進行放氣(qi)。
