A process of producing profiles whose cross-section is variable in the longitudinal direction, characterized by the process stages of cutting a blankwith a substantially constant width along a longitudinal direction, deforming the blankby deep-drawing to form an open profile whose cross-section is variable along the longitudinal direction, and cutting the flanges projecting from the open profile.

The invention concerns a rolling stand, a rolling train, and a method for rolling a stepped preprofiled metal strip. In order to guarantee that the metal strip is free of waviness in its longitudinal direction, even after individual thickness reduction of the steps, the invention proposes that the thickness reduction be carried out on a step-specific basis according to the following mathematical relationship: &#x394;h/h=&#x394;h/h=&#x3b5;=constant, where &#x394;hrepresents the amount of the thickness reduction in the region of the i-th step, and hrepresents the value of the resulting thickness of the metal stripafter rolling in the region of the i-th step.

A method and a device for flexibly rolling a metal band by guiding the metal band through a roll gap formed between a first working roll and a second working roll, and by varying the size of the roll gap in such a way that band sections with a greater band thickness and band sections with a lesser band thickness are obtained over the length of the metal band. In the device and method, the time of contact between each point on the circumference of the first working roll and the metal band is shorter in duration than the time of contact between each point on the circumference of the second working roll and the metal band such that an asymmetric band thickness profile is obtained in a region of the band sections with a lesser band thickness.

To produce sheet steel components optimised for loading, a steel strip is cast between two cooled rolls with a variable nip and the thickness of the steel strip is changed by changing the time of contact between the strand shells and the rolls or by changing the cooling intensity of the rolls on the molten steel cast into the gusset formed by the rolls, thereby changing the thickness of the steel strip. Such a strip has a homogeneous structure and can subsequently be given a special quality by hot or cold rolling for its particular purpose of use.

A method of shaping planar parts which have an elastic and plastic range for making components which are curved two dimensionally around two axes under utilization of a high pressure peening shot beam comprises the steps of tension positioning the part to obtain through elastic deformation to obtain the desired contour; peening the surface of the part to be deformed by running a beam of shot along track lines which are essentially lines of equal strain in the parts to be made; controlling the peening shot beam energy such that more central parts receive shot at a higher energy than more peripheral parts of said part; repeating the aforementioned steps on the other side of the part; and separately peening shot treating at least some of thicker edge parts, so as to obtain plastic deformation.

Process for producing metal parts

The invention relates to a method and apparatus for open-die forging of workpieces in forging presses at high forging temperatures, more particularly steel billets or ferrous alloy billets between about 800 and 1250 degrees Celsius. In conventional open-die forging it is often not possible to complete the forging process in a single heat, and the workpiece must therefore be reheated. Also, with direct contact between workpiece and tool, cracks occur, particularly in the vicinity of bulges, the prevention or straightening of which requires repeated transverse hammer- or pressure-forging, so lengthening the cooling time. The total energy consumption for deformation and heating of the workpieces is therefore relatively high. Reduction of this energy consumption, a surprising improvement in product quality, and almost complete elimination of bulges are achieved by means of the invention, in that during forging the workpiece undergoes lubrication effective at the forging temperature, the lubricant being a fluid glass film. The lubricant is advantageously applied in the form of a fine powder.

Open-die forging method

A method is provided for shaping an object consisting of a material which is both elastic and capable of permanent deformation, by deforming said object with a blast of solid particles.
