class="khcont">精密鋼管生產(chǎn)工藝特點(diǎn)：精密鋼管的生產(chǎn)工序，與用其它方式生產(chǎn)的大直徑鋼管的生產(chǎn)工序相比，有如下特點(diǎn)：原料準(zhǔn)備工序簡(jiǎn)單;原料上機(jī)后，管坯用一道工序就可做成;不需要矯直工序。精密無縫鋼管機(jī)的生產(chǎn)效率一直是人們?yōu)殛P(guān)注的問題。提高冷軋管機(jī)的生產(chǎn)效率就是提高冷軋精密無縫鋼管機(jī)的小時(shí)產(chǎn)量產(chǎn)量A、一般用下式進(jìn)行計(jì)算冷軋管機(jī)的小時(shí).從上式可知，提高軋厚壁無縫管機(jī)產(chǎn)量的個(gè)重要途徑就是提高軋管機(jī)的速度。要想提高軋管速度，必須首先解決軋管機(jī)機(jī)架的慣性力和慣性扭矩的平衡方法及具體結(jié)構(gòu)，各個(gè)零部件的強(qiáng)度和剛度以及潤(rùn)滑、冷卻、使用壽命等問題。加大送進(jìn)量，和提高延伸率人是提高軋管機(jī)產(chǎn)量的又一有效的措施。為此，采用環(huán)形孔型塊是理想的解決方法，它既有利于加長(zhǎng)機(jī)架行程又不過多地增加軋輥的直徑。</div><p><img
