A rolling mill with a cooling zone for cooling and scissors for cross-cutting metal strips, which are preferably made of steel. A method and a device enables metal strips with thicknesses >4 mm and/or metal strips made of high-strength materials to be cross-cut by the scissors arranged after a production line and a cooling zone. In the method, the metal strip (6) is cooled in the cooling zone (10) to a specified temperature profile in the longitudinal direction of the metal strip (6) such that the metal strip (6) has a higher temperature in the region of the strip head of the trailing metal strip portion (31) and the strip base of the leading metal strip portion (32) than in the upstream and downstream regions.

The invention essentially is characterized in that downstream of the casting machine and upstream of the rolling device, in particular immediately behind shears for cutting the thin slab or the pre-strip, there is provided a scrap removal device, in particular a coiling device that winds the thin slabs or pre-strip into a coil which is removed from the installation as scrap. Therefore, the quality of the coil winding is not important as the wound then slab or pre-strip need not anymore be advanced to the rolling train. The resulting coil can be lifted with a forklift and bind during the emergency maintenance of the rolling train, without use of any personnel. No additional crane is required for scrap removal. In addition, no constructional measures, e.g., construction of a gravel pit for material cut by shears, are necessary.

A continuous casting and rolling apparatus includes: a continuous casting device; a cutting device that is disposed at the output side of the continuous casting device and cuts an inner slab produced from the continuous casting device; a rolling device pressing down on the slab and disposed downstream of the continuous casting device in the moving direction of the inner slab; a tunnel furnace which is disposed between the cutting device and the rolling device and heats the slab disposed on the main path of the inner slab that is transferred from the continuous casting device to the rolling device; and a loading adjustment unit which is disposed adjacent to the tunnel furnace and unloads the slab from the main path from the outlet side of the tunnel furnace and loads the slab onto the main path from the inlet side of the tunnel furnace.

A method for cutting a cast strand or intermediate strip using shears. In order to facilitate improved rolling of the section having significantly reduced thickness, the method according has the following steps: a) bringing part of the completely solidified cast strand or intermediate strip in the conveying direction (F) of the cast strand or intermediate strip in front of the shears; b) placing a first blade of the shears onto the one surface of the cast strand or intermediate strip and placing a second blade of the shears onto the other surface of the cast strand or intermediate strip and performing a cut by carrying out a relative movement of the two blades, wherein at least one of the blades is in a pushed-forward position; c) upset forging or upset forging with stamping a wedge-shaped contour on the end of the cast strand.

A method for manufacturing a hot-rolled steel sheet having a large thickness and a large width, a larger sheet width and a lower temperature can stably be cut at a cutting load equal to that of a conventional steel sheet having a usual sheet thickness, a usual sheet width and a usual temperature. In a rough rolling step, the steel sheet is formed so that the shortest length L (mm) from a concave portion bottom to a convex portion top of the fishtail shape satisfies Equation (1) mentioned below, and an intermediate portion between the concave portion bottom and the convex portion top, defined as a desired cutting location, is cut:
(2X+30)L300(1),
in which X is a maximum deviation (mm) of the cutting location of a crop cutting machine and 0X90.

Methods for making Ta sputter targets and sputter targets made thereby. Ta ingots are compressed along at least two of the x, y, and z dimensions and then cross rolled in at least one of those dimensions. A pair of target blanks is then cut from the cross rolled ingot. The resulting targets have a predominate mix of {100} and {111} textures and have reduced B {100} and B {100} banding factors.

A metal plate for manufacturing a deposition mask with reduced variation in dimension of through-holes; wherein an average value of plate thicknesses of the metal plate in a longitudinal direction is within a 3% range around a predetermined value. When an average value of the plate thicknesses of the metal plate in the longitudinal direction is represented as A, and a value obtained by multiplying a standard deviation of the plate thicknesses of the metal plate in the longitudinal direction by 3 is represented as B, (B/A)100(%) is 5%. When a value obtained by multiplying a standard deviation of the plate thicknesses of the metal plate in the width direction by 3 is represented as C, and a value of a plate thickness of the metal plate at a central portion in the width direction is represented as X, (C/X)100(%) is 3%.
