软铝连续挤压工艺是国外七十年代发展起来的一种铝合金型材加工的新工艺,效率非常高,简称CONFORM。我国从国外购进过九条此类生产线,耗费上千万美元。其中液压系统约占150万美元。於1989年底,我国自行研制的生产线通过了国家验收。我厂承担了该生产线主机超高压液压系统的研制工作,各项指标均达到要求,系统压力脉动小於5%;压力发讯精度为5%;当保压时,四小时 Continuous extrusion of soft aluminum is the development of a seventies abroad, a new aluminum alloy processing technology, the efficiency is very high, referred to as CONFORM. China purchased nine such production lines from abroad, costing tens of millions of dollars. The hydraulic system accounts for about 1.5 million U.S. dollars. By the end of 1989, our own self-developed production line passed the national acceptance. I plant assume host of the production line of ultra-high pressure hydraulic system development, the indicators have reached the requirements of the system pressure pulsation of less than 5%; pressure accuracy of 5% of the sender; when the packing, four hours
