Abstract: A heating device and a method for the inductive heating of a flat steel strip in a hot rolling mill. The heating device is between two rolling trains of the hot rolling mill and the flat steel strip runs at a speed through the heating device in a transporting direction. The heating device includes: transverse-field modules arranged one after the other along the transporting direction of the flat steel strip; longitudinal-field modules arranged one after the other along the transporting direction of the flat steel strip and arranged before or after the transverse-field modules along the transporting direction; a first power supply supplying at least one transverse-field module with a first alternating voltage; and a second power supply supplying at least one longitudinal-field module with a second alternating voltage. The power supplies have a converter and an electrically connected capacitor bank with multiple capacitors connected in parallel.

Abstract: A method for preparing a high-performance tantalum target, a high-performance target prepared by the method, and a use of the high-performance target. The method for preparing the high-performance tantalum target comprises: firstly, preparing a tantalum ingot into a forging blank by a method of cold forging in conjunction with hot forging; then, rolling the forging blank by a hot rolling method; and finally, performing leveling, and performing discharging, milling and surface treatment according to a size of a finished product, so as to obtain the tantalum target. The tantalum target prepared by the method has uniform crystallization, with a grain size between 50 μm and 120 μm. A texture component where a texture (110) dominants in the thickness direction of the target is obtained. A total proportion of three textures (111), (110) and (100) is between 40% and 50%, ensuring a consistent sputtering rate of the tantalum target during use.

Abstract: In a rolling train, prior to being rolled, the rolled stock, or slab, produced in an ingot casting process, has the shape of a truncated pyramid with a base area, a top area and four side areas. During a first rolling pass sequence, two opposite side areas of the rolled stock are rolled in a first direction so that all of the cross-sectional areas of the rolled stock oriented transversely with respect to the rolling direction have the same surface area when the sequence ends. The rolled stock is rotated, e.g., through 90°, and during a second rolling pass sequence, the same two opposite side areas of the rolled stock are rolled in a second direction transversely with respect to the first direction. Thus, material of the rolled stock is automatically redistributed to a desired geometry with a high degree of precision and without the use of vertical rolling stands.

Abstract: A method for assigning surplus slabs in slab yards to orders includes loading slab pre-yards of a plurality of production lines with surplus slabs, describing the assignment of the surplus slabs to the orders with a mathematical model, grouping order data and slab data based on steel grades, obtaining an assignment scheme for the surplus slabs and the orders in each group with a mixed scatter search algorithm, and assigning the surplus slabs to the orders using the assignment scheme. If a surplus slab is in a pre-yard of a production line associated with an order the surplus slab is assigned to, the slab is moved using a crane to the production line. Otherwise, the slab is moved to the pre-yard associated with the production line, and then moved using a crane to the production line. The slab is then heated and rolled by the production line.
