The present invention provides an apparatus for cutting a material, comprising: a frame body installed on a conveying path of a material; a cutting means, mounted on the frame body, for cutting an end portion of the material being conveyed; a laser preheating means for preheating the material by irradiating a laser beam onto the material before being conveyed to the cutting means; and a blocking and reflection means for blocking the laser beams reflected to the cutting means and re-reflecting the laser beam to the material.

A manufacturing method of a cold-rolled steel sheet in which the method uses a full-width heating device that heats a steel sheet over an entire area in a width direction of the steel sheet, an edge heating device that heats end portions in the width direction of the steel sheet, and a cold rolling mill that rolls the steel sheet and that is arranged on a downstream side in a rolling direction with respect to the full-width heating device and the edge heating device, the method includes: heating the steel sheet by using the full-width heating device and the edge heating device in such a manner that temperatures of the end portions in the width direction becomes higher than a temperature of a central portion in the width direction of the steel sheet on an entry side of the cold rolling mill.

Energy-efficient production of a ferritic hot-rolled strip (6) in an integrated casting-rolling plant (1), which modifies the known processes for producing a ferritic hot-rolled strip (6) in an integrated casting-rolling plant (1) so that the ferritic hot-rolled strip (6) can be produced significantly more energy-efficiently but nevertheless has good metallurgical properties and a good surface quality.

A conveyor for transporting a product, the product being preferably in the form of respective articles, in particular articles of the tissue industry, including a means for supporting and guiding an endless conveyor belt, especially one of the type with articulated links, the belt including at least one respective positive stretch, in particular for transporting the product, and preferably a return stretch, if necessary positioned under the respective longitudinal transporting stretch; and means for driving the conveyor belt and including a means for engaging the respective link of the conveyor belt and, more specifically, means which are adapted to engage a rear-facing surface of the respective conveyor belt link, the means for engaging and driving the conveyor belt being adapted to engage a respective longitudinal stretch, preferably rectilinear, of the conveyor belt itself.

A method of hot forming an aluminum alloy component may include heating the aluminum alloy component in a heating furnace to a solutionizing temperature, cooling the aluminum alloy component to a desired forming temperature, deforming the aluminum alloy component into a desired shape in a forming device while the aluminum alloy component is at the desired forming temperature, maintaining a constant temperature during the deformation of the aluminum alloy component, and quenching the aluminum alloy component to a low temperature below a solvus temperature.

A manufacturing method of a cold-rolled steel sheet in which the method uses a transverse-type full-width heating device that heats a steel sheet over an entire area in a width direction of the steel sheet, and a cold rolling mill that rolls the steel sheet and that is arranged on a downstream side in a rolling direction with respect to the transverse-type full-width heating device, the method includes: heating the steel sheet by using the transverse-type full-width heating device in such a manner that temperatures of end portions in the width direction becomes higher than a temperature of a central portion in the width direction of the steel sheet on an entry side of the cold rolling mill.

A contactless looper for a metal substrate includes an entrance, an exit, and at least one deflection device between the entrance and the exit. The contactless looper is configured to receive a metal substrate moving in a processing direction from the entrance to the exit and impart a deflection along the processing direction in a metal substrate such that a position of the metal substrate at the at least one deflection device is vertically offset from a height of the metal substrate at the entrance of the looper. A method of processing a metal substrate with the contactless looper includes receiving the metal substrate at the entrance of the contactless looper along a passline, imparting a deflection in the metal substrate with the looper, and passing the metal substrate out the exit of the contactless looper.
