真(zhen)空熔(rong)(rong)(rong)(rong)煉(lian)爐可(ke)以對金(jin)屬(shu)(shu)進(jin)行(xing)(xing)熔(rong)(rong)(rong)(rong)煉(lian)和(he)提純,具(ju)體(ti)(ti)(ti)步驟如下: 1.準備(bei)原材料:將(jiang)(jiang)所需(xu)的(de)(de)(de)金(jin)屬(shu)(shu)或(huo)合金(jin)材料加(jia)工成(cheng)(cheng)小塊或(huo)粉末,并在容(rong)器(qi)中(zhong)加(jia)入適(shi)量的(de)(de)(de)熔(rong)(rong)(rong)(rong)劑(ji)。 2.真(zhen)空處理(li)(li):將(jiang)(jiang)容(rong)器(qi)放(fang)入真(zhen)空熔(rong)(rong)(rong)(rong)煉(lian)爐中(zhong),通過(guo)(guo)真(zhen)空泵(beng)抽出容(rong)器(qi)內部的(de)(de)(de)氣(qi)體(ti)(ti)(ti),形成(cheng)(cheng)真(zhen)空環境(jing)。在此過(guo)(guo)程中(zhong),需(xu)要注意(yi)控(kong)(kong)制真(zhen)空度(du)(du)和(he)抽氣(qi)速度(du)(du),以避免金(jin)屬(shu)(shu)受氧(yang)化(hua)(hua)或(huo)揮發。 3.加(jia)熱(re)熔(rong)(rong)(rong)(rong)化(hua)(hua):通過(guo)(guo)電加(jia)熱(re)器(qi)或(huo)感應線(xian)圈等設(she)(she)備(bei)對容(rong)器(qi)內的(de)(de)(de)金(jin)屬(shu)(shu)進(jin)行(xing)(xing)加(jia)熱(re),使其熔(rong)(rong)(rong)(rong)化(hua)(hua)并與熔(rong)(rong)(rong)(rong)劑(ji)混(hun)合均(jun)勻。 4.均(jun)勻冷卻(que):熔(rong)(rong)(rong)(rong)化(hua)(hua)后的(de)(de)(de)金(jin)屬(shu)(shu)會在熔(rong)(rong)(rong)(rong)劑(ji)中(zhong)緩慢冷卻(que),控(kong)(kong)制冷卻(que)速度(du)(du)和(he)溫(wen)度(du)(du)梯度(du)(du),有助于減少夾雜和(he)晶界問(wen)題。 5.精(jing)煉(lian)處理(li)(li):通過(guo)(guo)靜態保(bao)溫(wen)、旋轉熔(rong)(rong)(rong)(rong)煉(lian)(EPM)、電渣(zha)重(zhong)熔(rong)(rong)(rong)(rong)(ESR)等方法進(jin)行(xing)(xing)精(jing)煉(lian)處理(li)(li),以提高金(jin)屬(shu)(shu)的(de)(de)(de)質量和(he)純度(du)(du)。 6.澆注成(cheng)(cheng)型:將(jiang)(jiang)熔(rong)(rong)(rong)(rong)融狀態的(de)(de)(de)金(jin)屬(shu)(shu)均(jun)勻地(di)注入到模具(ju)中(zhong),經(jing)過(guo)(guo)冷卻(que)后得到所需(xu)的(de)(de)(de)鑄(zhu)件或(huo)其他產品。 真(zhen)空熔(rong)(rong)(rong)(rong)煉(lian)爐可(ke)以對金(jin)屬(shu)(shu)進(jin)行(xing)(xing)熔(rong)(rong)(rong)(rong)煉(lian)和(he)提純,需(xu)要嚴格控(kong)(kong)制氣(qi)氛、溫(wen)度(du)(du)、時間等參數,并注意(yi)保(bao)護金(jin)屬(shu)(shu)不受氧(yang)化(hua)(hua)或(huo)污染(ran)。在使用(yong)前,應該了解設(she)(she)備(bei)的(de)(de)(de)操(cao)作(zuo)方法和(he)作(zuo)用(yong)原理(li)(li),并根據具(ju)體(ti)(ti)(ti)材料和(he)工藝(yi)要求選擇合適(shi)的(de)(de)(de)設(she)(she)備(bei)和(he)加(jia)工工藝(yi)。
