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。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。</p><div
