A method for the continuous casting of metal strands. The liquid metal is simultaneously cast via a moulds into metal strands. The moulds each have a narrow side and a broad side. The moulds have a uniform narrow side so that the metal strands have equal thicknesses after casting. At least one of the moulds used has a broad side whose length differs from the length of the broad side of the other simultaneously used moulds. For each mould used, a sprue stone is provided, which is arranged on a casting table and is provided for receiving the starter strands. The casting of the metal strands includes a mould filling phase with a fixed casting table in which a plurality of starter strands is cast into the associated sprue stones. The casting includes a continuous casting phase in which the casting table is lowered and metal strands are cast.

Method for multiple casting of metal strands

An aluminum alloy for producing an aluminum strip for lithographic print plate carriers, a method for producing an aluminum alloy for lithographic print plate carriers, in which, during the production of the aluminum alloy, after the electrolysis of the aluminum oxide, the liquid aluminum, up to the casting of the aluminum alloy, is supplied to a plurality of purification steps, as well as an aluminum strip for lithographic print plate carriers and a corresponding use of the aluminum strip for lithographic print plate carriers include a carbide content of less than 10 ppm, and preferably less than 1 ppm. As a result, the aluminum alloy, the method for producing the aluminum alloy, the aluminum strip, and corresponding use of the aluminum strip for lithographic print plate carriers described herein allow for the use of virtually gas-tight coatings.

Aluminum alloy free from aluminum carbide

The invention relates to an aluminum alloy strip for the production of printing plate carriers comprising water-based coatings, wherein the aluminum alloy strip has a thickness of at most 0.5 mm. The object is to propose an aluminum alloy strip for the production of printing plate carriers comprising at least one water-based coating so that punctiform coating faults are prevented. The object is achieved for an aluminum alloy strip in that the aluminum alloy strip, in a longitudinal polished section prepared using water as a lubricant, has etch figures with a cubic etching, of which the longitudinal extent is at most 15 mm.

The apparatus has a starter bar of novel design which avoids the problems of deformation of the billet base, loss and waste of casting metal and loss of billet stability. The apparatus includes a tub-like having a peripheral wall and a central raised element or cone having tapered outer surfaces, to stabilize the base of the billet during casting and to dislodge the cooled billet as it shrinks.
