Also provided herein is a continuous casting system for producing thick gauge aluminum alloy articles. The disclosed thick gauge aluminum alloy articles can be provided in any suitable temper.

A control system is a control system of casting and rolling equipment having a twin roll-type continuous casting machine, a rolling mill, and a conveyor. The control system includes a rolling mill control unit that controls the rolling mill by any one of controls including a rolling control and an open control, a conveyor control unit that controls the conveyor by any one of controls including a tension control and a speed control, a first control unit that controls to perform the rolling control and the tension control, a second control unit that controls to perform the open control and the speed control, and a third control unit that controls to resume the tension control and the rolling control.

A continuous casting and rolling plant for the continuous production of steel bars or profiles, the plant comprising in sequence, along a processing line, a continuous casting machine adapted to cast a billet; a first cutting device; a second cutting device; a rolling train adapted to roll the billet; wherein the continuous casting machine comprises a crystallizer, and is adapted to cast the billet at least at a first casting speed v.sub.1 and at a second casting speed v.sub.2 greater than the first casting speed v.sub.1; wherein the first cutting device is arranged at a first distance from the crystallizer expressed in meters, along the processing line, calculated according to a specific mathematical relation.

Provided is an ultra high-strength hot-rolled steel sheet, having tensile strength of 800 MPa, and a method for manufacture same, the method enabling excellent surface quality, workability, weldability as well as significantly reduced deviation of the mechanical property in the width and length directions of the steel sheet by means of an endless rolling mode in a continuous casting-direct rolling process.

A method and a device for producing a continuous strip-shaped composite material. The device has at least one first casting machine, using which a continuous strand is produced, in particular from steel, at least one rolling stand, which is arranged in line with the first casting machine and downstream thereof. A fully solidified slab of the strand produced using the first casting machine can be hot rolled, and at least one second casting machine, using which a further continuous strand is produced from metal. Between the casting machines, on the one hand, and the rolling stand, on the other hand, a merging unit is arranged, by means of which the slabs can be moved in the direction toward each other in the hot state. The rolling stand is designed as a roll-cladding unit, by which a composite formed from the merged slabs can be hot rolled.

A process for manufacturing an aluminum-based alloy sheet directly from a molten aluminum-based alloy is described. In a continuous caster, such as a belt-caster, and directly from the molten aluminum-based alloy, a substantially solid and substantially thin aluminum-based alloy strip, thinner than about 10 mm, is continuously cast and simultaneously cooled with a compression force on the solidifying aluminum-based alloy in a range of about 2 to about 3000 pounds per linear inch of alloy strip width. The substantially solid aluminum-based alloy strip can then be rolled, so as to obtain the aluminum-based alloy sheet. The process can include pulse heating the aluminum-based allowed sheet.

A combined casting and rolling installation and to a method for operating the combined casting and rolling installation. The combined casting and rolling installation comprises a rough-rolling mill train, a discharging device, a first transporting device, a quenching device, and at least one severing device. The rough-rolling mill train is configured to roll a continuously cast hot billet to form a rough-rolled strip. The discharging device is downstream of the rough-rolling mill train with respect to a conveying direction of the rough-rolled strip. The severing device is between the rough-rolling mill train and the discharging device and cuts up a first sub-portion of the rough-rolled strip into a rough-rolled strip piece. The discharging device discharges the rough-rolled strip piece. The first transporting device connects the severing device to the quenching device and transports the rough-rolled strip piece to the quenching device, which is configured to quench the rough-rolled strip piece.
