style="text-indent:25px">鋁棒在進(jìn)入擠壓機(jī)之前是要預(yù)加熱的。傳統(tǒng)觀念認(rèn)為，鋁棒必須在加熱爐內(nèi)加熱到固溶溫度，但經(jīng)驗(yàn)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(yù)熱爐里達(dá)到固溶溫度。在現(xiàn)代鋁擠壓工廠里，鋁棒加熱爐的一個(gè)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(yù)熱區(qū)測(cè)溫典型的問題有：1.兩點(diǎn)式的熱電偶讀數(shù)會(huì)偏低。2.兩點(diǎn)式熱電偶的日常維護(hù)經(jīng)常被忽略。3.均勻化熱處理溫度是鋁棒的關(guān)鍵參數(shù)。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(diào)鋁棒在擠壓中的溫度變化。6.過度加熱和慢速擠壓都浪費(fèi)了預(yù)熱的能源。**企業(yè)意識(shí)到鋁棒應(yīng)該加熱到能夠擠壓的低溫度，同時(shí)必須保證擠壓機(jī)出口的溫度達(dá)到目標(biāo)值。通過降低鋁棒預(yù)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(shí)踐證明，這樣的改變能節(jié)省燃?xì)饧訜釥t15-20%的能耗。衢州LY12鋁棒價(jià)格實(shí)惠低熔點(diǎn),耐蝕性好，產(chǎn)品描述:具有耐熱、耐磨的特性。</p><div

style="text-indent:25px">鋁棒擠壓成鋁型材采用的熱擠壓工藝；熱擠壓是幾種擠壓工藝中較早采用的擠壓成形技術(shù)，它是在熱鍛溫度下借助于材料塑性好的特點(diǎn)，對(duì)金屬進(jìn)行各種擠壓成形。目前，熱擠壓主要用于制造普通等截面的長(zhǎng)形件、型材、管材、棒材及各種機(jī)器零件等。熱擠壓不僅可以成形塑性好，強(qiáng)度相對(duì)較低的有色金屬及其合金，低、中碳鋼等，而且還可以成形強(qiáng)度較高的高碳、高合金鋼，如結(jié)構(gòu)用特殊、不銹鋼、高速工具鋼和耐熱鋼等。由于坯料必須加熱至熱鍛溫度進(jìn)行擠壓，伴有較嚴(yán)重的氧化和脫碳等加熱不足，影響了擠壓件的尺寸精度和表面粗糙度。一般情況下，機(jī)器零件熱擠壓成形后，再采用切削等機(jī)械加工來提高零件的尺寸精度和表面質(zhì)量。</p><p
