A method and a system produces extrusion billets from scraps obtained from stamping, cutting and/or machining operations, in particular scraps made of magnesium or magnesium alloys, without subjecting these to a melting process. The system for carrying out the method is essentially composed of a storage unit for the scraps, a device for comminuting the scraps, a press for producing a round briquette, and an extruder for shaping the round briquette into a extrusion billet.

Method and plant for producing extrusion billets

The invention for working extruded profile sections with respect to the outer contours thereof by way of hot shaping and/or hot stamping and/or cutting operations and/or punching operations comprises the following method steps: &#x2014;inserting the profile sections () heated to a temperature in the range of 250 to 450&#xb0; C. into a two-part shaping tool () preheated to a temperature of 300 to 600&#xb0; C.; and &#x2014;applying pressure to the shaping tool () by way of one or more pressing cylinders () of a press (). The device for carrying out the method comprises a press () and a shaping tool, wherein the shaping tool () is formed of two tool halves I, II, which are displaceable with respect to each other, and between which the profile section () is inserted.

The aluminum-free magnesium alloy has a composition of at least 87.5 wt. % magnesium, produced by adding 0.5 to 2.0 wt. % cerium, 0.2 to 2.0 wt. % lanthanum, 0 to 5 wt. % of at least one further metal from the group of the rare earths, 1.5 to 3.0 wt. % of a manganese compound, and 0 to 0.5 wt. % of a phosphorus compound.

Aluminum-free magnesium alloy

A method for separating hollow sections after the extrusion process, the hollow sections being separated to create a component with a predefined geometrical shape by way of a punching operation.

Method and apparatus for separating hollow sections

Metal sheets () are produced from strand-shaped profiles () having a low thickness, made of magnesium or magnesium alloys by way of an extrusion system (). The open or closed extruded profile () exiting the extrusion die (-) of an extrusion press () is shaped to obtain a flat metal sheet () and is then subjected to a defined shaping process by way of stretch-forming. The system for carrying out the method is essentially composed of an extrusion press () comprising a die plate generating the extruded profile and a shaping unit () following the die plate, wherein the shaping unit () is composed of a severing unit (), a bending unit (), and an unrolling unit ().
