前言我国铜及其合金挤压工具消耗量很大,主要是使用寿命不长。影响其寿命的因素很多,诸如挤压设备、挤压工具设计、制造挤压工具村料、工具的加工质量、铜及其合金的工艺性能和生产操作等的影响。工具的大量消耗,增加了挤压生产成本,降低了整体竞争力。提高工具使用寿命,避免或 Preface China's copper and its alloy extrusion tools consumption is large, mainly the service life is not long. There are many factors that affect their life span, such as extrusion equipment, design of extrusion tools, manufacturing of extrusion tool materials, processing quality of tools, process performance of copper and its alloys and production operations. Large tool consumption, increased extrusion production costs, reducing the overall competitiveness. Improve tool life, avoid or
