摘要： The object of providing a method for conditioning a working roll with which the material properties of a working roll can be set in a process-reliable and uniform manner is achieved by a method in which a roll and at least one pressure tool are rotated relative to each other, in which pressure is applied locally to the roll by means of the at least one pressure tool, comprising at least one pressure element, via the at least one pressure element, and in which a deep rolling process is carried out.

摘要： A cemented carbide comprising 55-90 parts by mass of WC particles, and 10-45 parts by mass of an Fe-based binder phase, the binder phase having a composition comprising 2.5-10% by mass of Ni, 0.2-1.2% by mass of C, 0.5-5% by mass of Cr, 0.2-2.0% by mass of Si, 0.1-3% by mass of W, 0-5% by mass of Co, and 0-1% by mass of Mn, the balance being substantially Fe and inevitable impurities, and the cemented carbide being substantially free from composite carbides having major axes of 5 μm or more. This cemented carbide is produced by cooling at a cooling rate of 60° C./hour or more between 900° C. and 600° C., after vacuum sintering.

摘要： A planishing roll has a surface structure, in particular for producing flat products from a metallic material, in particular from a steel material. The surface structure has a material ratio of 2% at a depth of 0.2 μm to 9 μm, preferably at a depth of 0.8 μm to 5.5 μm. The depth is measured, starting from a zero line, in the direction of an axis of rotation of the planishing roll, with the zero line running parallel to the axis of rotation of the planishing roll and. Starting from the surface of the planishing roll, the zero line is displaced in the direction of the axis of rotation of the planishing roll until the material ratio of the planishing roll is 0.1%.

摘要： This invention relates to thermal spray coatings and processes onto non-smooth surfaces. The coating and processes can coat non-smooth surfaces without substantial degradation of the underlying surface texture or profile of the non-smooth surfaces so as to sufficiently preserve the underlying surface texture or profile. The ability for coating fractional coverage to maintain the surface profile while maintaining wear resistance is unprecedented by conventional thermal spray processes.

摘要： An inner roller used for roll forming pipe elements has a flange extending radially from a body. The flange has a surface divided into annular surface portions. The surface portions have orientation angles measured relatively to the axis of rotation of the inner roller. The orientation angles of surface portions farther from the body have greater orientation angles than the surface portions nearer to the body to mitigate adverse frictional effects between the pipe element and the flange during roll forming.

摘要： The present invention relates to a method for manufacturing a component of austenitic TWIP or TRIP/TWIP steel. A flat product (1) is deformed by achieving at least one indentation (16) on at least one surface of the flat product (1) in order to have in the deformed product (5) areas of a high strength steel embedded in a matrix of a ductile material. The invention also relates to the use of the component where areas of a high strength steel embedded in a matrix of a ductile material are required in the same component.
