    摘要： The invention relates to a method for processing a steel product, in which the steel product is passed between a set of rotating rolls of a rolling mill stand in order to roll the steel product. According to the invention, the rolls of the rolling mill stand have different peripheral velocities such that one roll is a faster moving roll and the other roll is a slower moving roll, and the peripheral velocity of the faster moving roll is at least 5% higher and at most 100% higher than that of the slower moving roll, and the thickness of the steel product is reduced by at most 15% per pass, and the rolling takes place at a maximum temperature of 1350°C. The invention also relates to a steel product produced using the method, and to the use of this steel product.

    摘要： Metal parts, in particular made from ultra high strength steel, are welded together by using a welding laser beam, which is focused on the material (M) in at least part of a welding zone. After the laser welding, a heat treatment is performed by heating the material by a post weld heat treatment (PWHT) laser beam. The PWHT laser beam (PLB) generates heat in the metal parts preferably by defocusing a laser beam in the welding zone. Preferably, one laser device generates both the welding laser beam and the PWHT laser beam.

    摘要： The invention relates to a method for the purification of a molten metal containing one or more foreign elements. The invention is characterised in that the molten metal is cooled to a eutectic temperature to simultaneously form purified metal crystals and crystals containing at least one foreign element, and in that at least some of the crystals containing at least one foreign element are separated from the purified metal crystals by using a solid-solid separation technique.

    摘要： The invention relates to a method for fractional crystallisation of an at most partially solidified molten metal, in which a layer of at most partially solidified molten metal having an upper surface und a lower surface is divided into a series of compartments communicating with each other, in which the metal is stirred in at least some of the compartments, und in which crystals formed und/or existing in the layer of metal are selectively transported in a predetermined direction und molten metal is selectively transported in the opposite direction.

    摘要： This invention relates to a method for manufacturing a metal tubular blank suitable for forming into a product comprising the steps of

    providing an essentially planar blank, said planar blank having a first surface and a second surface;
    producing the tubular blank from the planar blank whereby the second surface of the planar blank becomes the outside of the tubular blank;
    wherein a first layer with a first friction influencing function is applied to at least part of the first side of the planar blank and/or a second layer with a second friction influencing function is applied to at least part of the second side of the planar blank prior to forming the planar blank into a tubular blank, so as to influence the friction between the tubular blank and forming tools which can be used to form the tubular blank into the product, and wherein the first and/or second layer are applied in the form of a foil, a dry lubricant, a wax or an oil. The invention further relates to a tubular blank and a product produced from such a tubular blank.
