氣動初矯正機械的開發(fā)與應(yīng)用

Development and Application of Pneumatically-operated Pipe Pre-straightening Machine

摘要: 無縫鋼管經(jīng)過拔制、熱處理、冷卻等生產(chǎn)工序后會產(chǎn)生彎曲。當(dāng)管子彎曲度超過一定范圍后即不便于進入七輥矯直機矯直,從而影響鋼管的正常生產(chǎn)。為此,新余新鋼特殊鋼有限責(zé)任公司鋼管廠新設(shè)計裝配了1套氣動初矯正機械,對鋼管進行初矯正。安裝使用后,滿足生產(chǎn)需求,并使單機產(chǎn)量提高12%以上。

Abstract: During the process of seamless steel tube manufacturing, after the operation steps namely, drawing, heat treatment and cooling, the product normally becomes bent. In case the bent is beyond a normal range, it will be hard for the tube to get through the 7-high straightener, influencing the normal cycle of the production negatively. Addressing this problem, a pneumatically-operated pipe pre-straightening aggregate is designed and installed by and located at the Steel Tube Plant, Xinyu Xingang Specialty Steel Co., Ltd. Actual operation result shows that the said pre-straightening machine is capable of meeting the production demand, having the productivity of the individual operation line increased by over 12%.
