摘要： Systems, devices, and methods are described for extruding materials. In certain embodiments, one or more hollow billets are loaded onto an elongate mandrel bar and transported along the mandrel bar to a rotating die. The billets are transported through fluid clamps, which engage the mandrel bar and provide cooling fluid to the mandrel bar tip, and through mandrel grips, which engage the mandrel bar and prevent the mandrel bar from rotating. One or more press-rams advance the billets through a centering insert and into the rotating die. A quench assembly is provided at an extrusion end of the extrusion press to quench the extruded material. A programmable logic controller may be provided to control, at least in part, operations of the extrusion press system.

摘要： The method consists of subjecting a coarse-grained titanium semi-product (1) with the pure titanium content of at least 99 wt % to a plastic deformation. In said plastic deformation the transverse cross-section surface area of the titanium semi-product is reduced by hydrostatic extrusion in which the titanium semi-product is the billet (1) extruded through the die (4). The reduction (R) of the transverse cross-section of the titanium billet (1) is realized in at least three but not more than five consecutive hydrostatic extrusion passes at the initial temperature of the billet (1) not above 50° C. and the extrusion velocity not above 50 cm/s. Prior to each hydrostatic extrusion pass, the titanium billet is covered with a friction-reducing agent. During the first hydrostatic extrusion pass, the reduction of the transverse cross-section surface area of the titanium semi-product is at least four, whereas during the second and third hydrostatic extrusion pass it is at least two and a half.

摘要： Processes by which bulk forms can be produced in a single continuous operation, as opposed to multi-stage deformation processes that involve a series of separate and discrete deformation operations or stages. Such processes generally entail deforming a solid body using a large-strain extrusion machining technique and deformation conditions that obtain a predetermined crystallographic texture in the continuous bulk form that differs from the crystallographic texture of the solid body.

摘要： Extrusion of feed materials of a high temperature formable non-ferrous metal susceptible to embrittlement during air processing uses an extrusion system having a rotatable wheel and shoe covering part of the length of a groove around the periphery of the wheel to form an arcuate passageway, the shoe having an abutment which substantially closes a second end of the passageway and an extrusion die spaced from the abutment by a die chamber. The process includes pre-heating the feed material to not less than about 390° C. in a chamber defined by a feeder device, maintaining a protective atmosphere in the chamber of the feeder device while the feed material is heated. The pre-heated feed material then is passed to an inlet end of the passageway, and drawn along the passageway, to be forced by the abutment into the die chamber and through an extrusion orifice of the die to provide extruded product.
