關(guān)于我國(guó)小型無縫鋼管生產(chǎn)機(jī)組改造的探討

Discussion on Modification of Domestically-serving Small-sized Seamless Steel Pipe Mills

摘要: 以穿孔+冷拔生產(chǎn)工藝為代表的小型無縫鋼管生產(chǎn)機(jī)組在我國(guó)有很長(zhǎng)的歷史,曾對(duì)國(guó)民經(jīng)濟(jì)發(fā)展做出過巨大貢獻(xiàn),但存在工藝技術(shù)裝備落后,產(chǎn)品質(zhì)量差,原料和能源消耗大,污染嚴(yán)重,勞動(dòng)條件差等問題,因此改造小型無縫鋼管生產(chǎn)機(jī)組勢(shì)在必行。提出了Φ114mm(半)限動(dòng)芯棒連軋管機(jī)組和Φ114mmCPE頂管機(jī)組是改造小型無縫鋼管生產(chǎn)機(jī)組比較理想的機(jī)型選型建議。

Abstract: With so long a history of operation in the country,the small-sized seamless steel pipe mills featur-ing employment of piercing-cold drawing process once made great contributions to development of the national economy.However such pipe mills still stay with a number of shortcomings such as backward technological equip-ment,inferior product quality,high energy and material consumptions,serious pollution and poor labor condi-tions,etc.,and thus badly need to be modified.It is proposed in the paper that the Φ114 mm(semi-) mandrel pipe mill and the Φ114 mm CPE push-bench mill be the ideal mill types for modification of the small-sized seamless pipe mills.
