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.
