Combined rolling and extruding method and the device for performing the same

A method for combined rolling and extruding of cast billet is proposed. When implementing the method for combined rolling and extruding of metals or alloys, a cast billet with a predetermined temperature is fed to the working gauge, in which it is rolled and then to the die, through which the cast billet is extruded. When the cast billet is fed into the working gauge, a cladding layer of metal or alloy is created on the surfaces of the rolls by extruding the cast billet through the gaps formed between the surfaces of the rolls and the die. This invention makes it possible to improve the quality of the resulting products, as well as to increase the efficiency of the process as a whole.

METHODS OF MAKING A WIDE METAL SHEET

The present disclosure provides a method of preparing a metal sheet. The method includes extruding a component along an extrusion axis. The component has a wall at least partially defining an interior region. The component includes a metal. The method further includes unfurling the wall to form a sheet precursor. The sheet precursor has a first thickness and a first transverse dimension. The method further includes rolling the sheet precursor along a rolling axis to form the metal sheet. The metal sheet has a second thickness perpendicular to the rolling axis. The second thickness is less than the first thickness. The second transverse dimension is parallel to the rolling axis. The second transverse dimension is greater than the first transverse dimension. In certain aspects, the metal includes lithium and the metal sheet is a lithium metal electrode.

Nonferrous extrusion handling systems and processes

The specification discloses a nonferrous extrusion system and process providing improved transfer of extrusions from the runout table to the cooling table. The runout table includes interleaved runout rollers and transfer rollers that are vertically shiftable with respect to one another. The transfer rollers additionally are horizontally shiftable between the runout table and the cooling table. The runout table receives extrusions in a longitudinal direction. The vertical and horizontal shifting of the rollers is controlled to transfer the extrusions from the runout table to the cooling table.
