摘　　要：以核级锆管挤压为例,分析了锆合金挤压工艺的技术要求,对挤压过程的关键技术进行了研究:采用专用润滑剂,遵照合理的润滑工艺,实现坯锭及挤压工具的充分润滑;采用立式托盘输送系统及立式感应加热炉,保护坯锭表面的润滑涂层;采用活动扩孔头进行扩孔的工艺,保护穿孔针的润滑涂层;采用带穿孔动梁的穿孔系统,提高穿孔针的运行精度。研究成果已得到成功应用,实际表明,各项技术保障了锆合金挤压的顺利进行,提升了设备机组的综合性能。According to the requirements of nuclear-grade zirconium alloy extrusion process, the key equip- ment technologies of zirconium pipe production are analyzed. By using special lubricant under reasonable process, billet and extrusion tools can be lubricated sufficiently. Vertical transport line with support plates and vertical induction heating furnace are used to protect lubrication layer of billet. Removable reamer is adopted to ensure the lubrication adhered to mandrel remain intact. Piercing system with moving erosshead is em- ployed to improve operating accuracy of piercer. And the practice shows that the technical measures men- tioned above improved the extrusion flow of zirconium alloy, and also enhanced the comprehensive perform- ance of extrusion equipment.
