The invention relates to a method for producing metal sheets (B) from a magnesium melt (S), which comprises the following steps: producing the magnesium melt (S), casting the magnesium melt to a cast strip (M), immediately after casting, strip-rolling the cast strip (M) to a rolled strip (W), cross-cutting (6) the rolled strip (W) to metal sheets (B), rolling (14) the metal sheets (B) to a final thickness, the rolling of the metal sheets (B) being carried out, in relation to the metal sheets (B), in a direction (Q) at an angle to the rolling direction (L) of the strip rolling, said direction being maintained during the entire rolling of the metal sheets (B). The invention provides a simple method for producing very wide sheets that meet the requirements of the ultimate user.

Disclosed are a method and a production line for manufacturing metal strips made of copper or copper alloys by means of casting and rolling. In order to lower the investment cost and operating expenses therefor, the melt (2) is cast into a copper strip (4) in a vertical and/or horizontal continuous strip casting process (3), and the hot copper strip (4) is cleaned by milling (5) the top and bottom face (5a, 5b) thereof, is subjected to a cold rolling process (6), and is prepared for shipping, or is subjected to an inspection (12) and then prepared for shipping after being annealed (7), pickled (8), washed (9), dried (10), and optionally temper rolled (11).

Starting from a continuous casting furnace (1), fed with scraps, ingots or any other aluminum presentation, the cast metal is urged to pass through a solidification and rolling machine (5), a 19 mm-thick aluminum sheet being obtained. Then, this sheet is subjected to three successive hot rolling phases in respective rolling towers (8-8'-8"), attaining at its outlet a 1.5 mm thickness. Then, the aluminum sheet is subjected to two cold rolling phases until attaining a 0.54 mm thickness and, after intermediate annealing, it is subjected to a final cold rolling phase in which the definitive 0.25 mm thickness is obtained. The process achieves cutting the time of 34 hours corresponding to a classic continuous casting process down to 19 hours.

The invention relates to a method for producing a magnesium hot strip. According to said method, a melt consisting of a magnesium alloy is continuously cast to produce a pre-strip with a maximum thickness of 50 mm. Said cast pre-strip is hot-rolled directly from the casting heat into a hot strip with a maximum thickness of 4 mm at a hot-rolling starting temperature of at least 250 DEG C and at most 500 DEG C. A reduction in thickness of at least 15 % is achieved in the first hot-rolling pass. The inventive method enables magnesium sheets with improved deformability to be produced more economically.

The invention relates to a method for producing welded Cu and Cu alloy pipes in a combined production line, comprising a casting installation for ingoing materials, a hot-rolling mill, a pipe forming and welding installation and a drawing device for the welded pipe. The inventive method is characterized by the following steps: a) a quasi continuous initial strip is cast, b) the cast initial strip is hot-rolled at a rolling speed = casting speed x extension to form an intermediate strip, c) the intermediate strip is cooled at

A method is disclosed for improving the continuous casting process for making copper by using a probe (15) and analyzer (22) which measures the gases present in the molten copper (16) and controls the process based on the analyzer (22) results.
摘要:
A method for manufacturing aluminium alloy can body stock including a continuous, in-line sequence of hot rolling, annealing and solution heat treating without intermediate cooling and rapid quenching. Molten metal is delivered from a furnace 1 to a degassing and filtering device 2. It is immediately converted to a cast feedstock 4 in a casting apparatus 3, whence it is moved through pinch rollers 5 into hot rolling stands 6 and then to a heater 7. A quench station 8 follows the heater 7. More rolling stands 9 follow and the resulting strip or slab 4 is coiled on a coiler 12 after passing through surface inspection and thickness measurement devices 10, 11.
