热挤压工艺是生产不锈钢、高温合金及其它高合金钢管材和异型材的重要方法。大吨位卧式双动正向钢挤压机是指带独立立式穿(扩)孔系统的卧式正挤压机,最大挤压力在40MN以上,挤压速度较大,挤压品种主要为钢。本文介绍了大吨位卧式双动正向钢挤压机国内外应用现状,重点讨论了其设计及使用过程中普遍存在的问题,包括设备、工艺、工模具及润滑问题,并提出了优化措施。
Hot extrusion process is the production of stainless steel, high temperature alloys and other high alloy steel pipe and profile an important method. Large tonnage horizontal double acting forward steel extruder refers to horizontal vertical extrusion machine with independent vertical wear (expanding) hole system, the maximum extrusion pressure is above 40MN, the extrusion speed is big, the extrusion type is mainly Steel. This paper introduces the application status of large tonnage horizontal double acting forward steel extrusion press at home and abroad, and focuses on the ubiquitous problems in design and use, including equipment, process, tooling and lubrication, and puts forward the optimization measures .
