少機(jī)架三輥連軋管機(jī)組生產(chǎn)小直徑鋼管實(shí)踐

Practice of Manufacturing Small-sized Steel Pipes with Less Stand 3-roll Mandrel Mill

摘要: 以我國(guó)小直徑無(wú)縫鋼管的生產(chǎn)現(xiàn)狀及存在的問(wèn)題為背景，詳細(xì)介紹了Φ76 mm少機(jī)架三輥連軋管機(jī)組在生產(chǎn)小直徑無(wú)縫鋼管上的實(shí)際應(yīng)用情況。實(shí)踐證明：采用少機(jī)架三輥連軋管機(jī)組生產(chǎn)小直徑無(wú)縫鋼管，具有投資小、生產(chǎn)靈活、易于掌握，能夠適應(yīng)小直徑無(wú)縫鋼管批量小、更換規(guī)格頻繁等生產(chǎn)特點(diǎn)，是小直徑無(wú)縫鋼管生產(chǎn)較理想的機(jī)組選型。

Abstract: Based on the current situation of domestic production of small-sized seamless steel pipes, and relevant existing problems, the actual application of the Φ76 mm less stand 3-roll mandrel mill to produce small-sized seamless steel pipes is detailed here in the paper. The operation practice with the said mill leads to such a conclusion that when it comes to producing small-sized seamless steel pipes, the mandrel mill is in possession of such advantages as low initial investment, high production flexibility, easy operation, and suitability for small lot order and frequent size-change, being an ideal mill type for production of small-sized seamless steel pipes.
