Accu Roll軋管機(jī)芯棒內(nèi)水冷管連接改進(jìn)

Innovation of Inner Water Cooling Piping Connection of Mandrel on Accu-Roll Mill

摘要: 針對(duì)煙臺(tái)魯寶鋼管有限責(zé)任公司Accu Roll軋管機(jī)芯棒內(nèi)水冷管連接上存在的問題,分析了造成水管斷裂的原因,并進(jìn)行了改進(jìn)。采用四層鋼絲的高壓膠管部分替代無縫鋼管,消除了在軋制過程中因冷卻水管在芯棒支撐段內(nèi)反復(fù)甩動(dòng),而對(duì)水管和法蘭盤造成的不利影響;并對(duì)芯棒小車和回水系統(tǒng)結(jié)構(gòu)進(jìn)行了部分改進(jìn)。由此保證了產(chǎn)品質(zhì)量,降低了芯棒消耗。

Abstract: Taking the existing connection problems into consideration, the co-authors analyze the causes for the inner cooling water pipe of the mandrel on the Accu-Roll mill located at Yantai Lubao Steel Tube Corp., Ltd.. The harmful effects on the water piping and flanges by the repeated tremble of the cooling water piping in the mandrel supporting section during rolling are removed by means of using 4-layer-cable high pressure rubber pipes to replace the original seamless steel pipes. In addition, the mandrel car and the water returning system are also partially modified in order to guarantee the product quality and reduce the mandrel consumption.
