class="khcont">這種鋼管在性能方面，就不是那么的，而且還有著一個(gè)，非常嚴(yán)重的缺點(diǎn)，那就是很容易生銹。一旦要是管道生銹了，這不僅僅會(huì)引發(fā)，自來(lái)水的重金屬含量超標(biāo)，讓飲用的人畜，出現(xiàn)重金屬中毒的問(wèn)題;而且這也會(huì)帶來(lái)，一定的經(jīng)濟(jì)損失，畢竟更換這些管道，所需要的花費(fèi)可不小。這樣的一種情況，一直持續(xù)到了，精密無(wú)縫鋼管的出現(xiàn)，才被徹底的解決。甚至可以說(shuō)，精密無(wú)縫鋼管促進(jìn)了，運(yùn)輸行業(yè)的發(fā)展。因?yàn)榫軣o(wú)縫鋼管，自身的使用性能，就是十分的。而且精密無(wú)縫鋼管，對(duì)于管道的抗氧化性能，也是十分的重視。在制作精密無(wú)縫鋼管的過(guò)程中，就加入了一些抗氧化的處理。這使得精密無(wú)縫鋼管，即使長(zhǎng)時(shí)間與水接觸，也不會(huì)輕易的生銹。這然運(yùn)輸行業(yè)，再也不用為了，延長(zhǎng)管道的使用壽命，而花費(fèi)大量的財(cái)力與物理，對(duì)管道進(jìn)行維護(hù)了。而使用壽命的增加，也減少了運(yùn)輸行業(yè)，前期投入的成本。</div><p><img

class="khcont6">孔型封閉性差:20#精軋管機(jī)孔型中封閉較好的變形段是軋輥喉徑，從喉徑處往前、往后孔型的封閉性均較差，這對(duì)軋制薄壁管不利。軋制薄壁管和極薄壁管導(dǎo)盤(pán)消耗量較大:在軋制D/S≥38的荒管時(shí)，寬展量大，導(dǎo)盤(pán)間距收小，導(dǎo)盤(pán)與軋輥之間的間隙小，導(dǎo)盤(pán)磨損量大，還容易造成導(dǎo)盤(pán)崩邊。軋制荒管頭尾削尖技術(shù):在連軋管機(jī)上將毛管兩端削尖減薄是很困難的，因?yàn)檐堉茐毫μ?，同時(shí)也沒(méi)有用來(lái)改變孔型尺寸的適當(dāng)時(shí)間，軋制速度太高。但在20#精軋管機(jī)組上，毛管的軋制速度約為連軋管軋機(jī)速度的1/6，在軋制管端時(shí)就由時(shí)間來(lái)改變軋輥壓下以便得到所希望的管段減薄削尖，以利于張力減徑提高成材率，今后，這是一個(gè)研究點(diǎn)。<br /> 提高芯棒限動(dòng)速度:目前速度為0.08-0.30m/s。芯棒限動(dòng)速度過(guò)低，芯棒與軋件內(nèi)表面相對(duì)速度大，摩擦力大，芯棒磨損就大；芯棒限動(dòng)速度高，則有利于金屬軸向流動(dòng)，提高荒管出口速度。</div><div id="1zr1vx7" class=imgtipsbox>點(diǎn)擊查看德福鋼管(佛坪縣分公司)的<a
