style="text-indent:25px">鋁棒其工藝過程如下：首先將電解鋁錠加入合金元素進行熔煉鑄造成圓棒，將長棒切成短棒，將短棒進行加熱，同時也要將所使用的模具進行加熱，然后在擠壓機上對加熱好的圓棒進行擠壓成型，如果鋁型材采用T5交貨狀態(tài)，可以采用機前風冷淬火，對型材進行拉伸矯直、定尺鋸切、裝框，較后進行人工時效。如果鋁型材還需要進行陽極氧化、電泳涂漆、粉末噴涂等表面處理，再進行相應的表面處理，這就是鋁型材生產的大致工藝過程。也可以簡單歸納如下：電解鋁錠---熔煉---鑄造-----鋁棒鋸切----鋁棒加熱----熱擠壓成型---風冷淬火---拉伸矯直----定尺鋸切-----人工時效-----表面處理（陽極氧化、電泳涂漆、粉末噴涂等）。</p><p style="text-indent:25px">鋁棒在進入擠壓機之前是要預加熱的。傳統觀念認為，鋁棒必須在加熱爐內加熱到固溶溫度，但經驗顯示這不是一定的。只要鋁棒被正確的鑄錠和均化，就沒有必要在鋁棒預熱爐里達到固溶溫度。在現代鋁擠壓工廠里，鋁棒加熱爐的一個目的就是讓金屬軟化。如果金屬加熱不夠，就沒有辦法順利通過模具。如果鋁棒加熱過熱，擠壓的速度就必須很低。在鋁棒預熱區(qū)測溫典型的問題有：1.兩點式的熱電偶讀數會偏低。2.兩點式熱電偶的日常維護經常被忽略。3.均勻化熱處理溫度是鋁棒的關鍵參數。4.操作者傾向于過度加熱鋁棒。5.操作者傾向于降低擠壓速度來微調鋁棒在擠壓中的溫度變化。6.過度加熱和慢速擠壓都浪費了預熱的能源。**企業(yè)意識到鋁棒應該加熱到能夠擠壓的低溫度，同時必須保證擠壓機出口的溫度達到目標值。通過降低鋁棒預熱溫度，擠壓速度就可以提上來，這樣加熱爐的能量消耗就減少了。實踐證明，這樣的改變能節(jié)省燃氣加熱爐15-20%的能耗。7000系列鋁棒顯示7075主要含有鋅元素。</p><div

style="text-indent:25px">鋁棒熔煉過程要對鋁液進行變質處理，變質處理在精煉前進行，鋁液從熔化爐轉入轉澆包前，在爐底加入變質劑，以合金的方式加入，不直接加入變質元素，常用鋁鍶合金桿作為變質劑。Sr為長效變質劑，變質時間可持續(xù)6～8h，使得粗大片狀硅細化，成為細小組織，進一步改善機械性能，這種變質效果比在熔煉爐里加入進行變質效果好，可以減少燒損及衰退。Sr在爐底融化后，利用旋轉除氣進行攪拌均勻，減輕偏析，Sr變質后的鋁液吸氫比較快，產生針眼多，精煉后停留時間不能太長，超過1h需要重新測氫合格后才能使用。鋁液在轉入轉澆包后，撒入清渣劑，深度攪拌，打出渣灰。測量鋁液溫度是否能達到精煉溫度，溫度過高，需要加入回爐材料降溫，溫度較低需通電升溫，精煉溫度控制在720～740℃。直到調整合格后再在表面撒入少量清渣劑，除氣精煉主要是除氣除氫，由于一次深度攪拌已經除去大部分夾渣，但內部還有少量鋁渣，所以第二次撒入少量清渣劑。鋁棒根據外形可分為：圓鋁棒、方鋁棒、六角鋁棒、梯形鋁棒等。舟山6061鋁棒銷售</p><p
