摘　　要：温挤压兼备了冷挤压和热挤压工艺的优点,同时也避免了其缺点,它的一个关键技术就是润滑措施,良好的润滑剂可以有效地提高金属材料的塑性成形能力和模具的使用寿命。本文从温挤压润滑剂的性能要求出发,分析了温挤压润滑剂基本材料的润滑效果,总结出在不同挤压温度下不同材料所使用的各种润滑剂,介绍了目前几种实用的温挤压润滑剂,并对温挤压模具冷却方式进行了探索和尝试。Warm extrusion has the advantages of the cold extrusion and hot extrusion, and avoids their defects. The key technology of warm extrusion is the lubrication measure. Good lubricants can improve plastic forming ability of metal materials and mold life. The performance requirements of warm extrusion lubricant was analyzed to sum up the lubricants used in different extrusion temperatures and different materials, and several practical warm extrusion lubri- cants were introduced. The cooling method for warm extrusion die was developed.
