摘要: 连续挤压包覆技术是在连续挤压技术基础上发展起来的一种新型塑料加工技术,坯料在摩擦力作用下被挤压轮拽入并随其旋转和变形,压入模腔并与模腔中的钢芯复合得到复合材。挤压轮的工作温度为200~250℃,轮槽表面最高温度达590℃。文中叙述了挤压轮的工作条件、主要失效形式、挤压轮用钢的基本性能要求以及国内外挤压轮用钢的化学成分、研究进展和发展趋势。

Abstract: The continuous extrusion cladding technology is a new plastic making process developed based on continuous extrusion technology, of which the billet piece is dragged in by extrusion wheel at effect of friction force, turned with wheel and deformed, extruded in mould to clad the steel core in mould cavity and get cladding product. The service temperature of extrusion wheel is 200 ~ 250℃ and the highest temperature at surface of wheel trough is up to 590℃. The service conditions and main failure form of extrusion wheel, basic requirement for properties and chemical composition of steel for extrusion wheel, its status of research and development trend at home and abroad are presented in this article.
