摘要： A process for direct smelting metalliferous feed material is disclosed. Iron oxides are partially reduced in a solid state in a pre-reduction vessel. The partially reduced iron oxides are smelted to molten iron in a direct smelting vessel which contains a molten bath of iron and slag and is supplied with a solid carbonaceous material as a source of reductant and energy and with an oxygen containing gas for post-combusting carbon monoxide and hydrogen generated in the vessel. The direct smelting step generates an off-gas that contains sulphur and the off-gas is released from the direct smelting vessel. Part only of the off-gas released from the direct smelting vessel is used in the pre-reduction step to pre-reduce iron oxides in the pre-reduction vessel. Part only of the off-gas is used in the pre-reduction step in order to control the amount of sulphur that is returned with the partially reduced iron oxides to the direct smelting vessel.

摘要： A widthwise-compressing machine for applying a compression force through press tools to a material (1) to reduce a width of the material while applying vibrations to said material (1) to forcibly vibrate said material has a compression unit (3) for producing a compression force forming a working force, and a vibration-applying unit (4) for applying the vibration to said material (1). The vibration-applying unit (4) is provided independently of the compression unit (3). In the widthwise-compressing machine, when the material (1) is plastically worked, the material can be vibrated at an extremely high frequency to make it possible to resonate the material, thereby allowing the plastic-deformation thereof to be promoted.

摘要： Heißes Walzgut (1) aus Metall wird in mindestens einem Walzgerüst (2) gewalzt und sodann in einer dem mindestens einen Walzgerüst (2) nachgeordneten Kühlstrecke (5) gekühlt. Mittels einer Schallgeneratoranordnung (8) generierter Schall wird mittels einer Koppeleinrichtung (10) in das Walzgut (1) eingekoppelt, so dass sich zumindest in demjenigen Bereich des Walzguts (1), der sich in der Nähe der Koppeleinrichtung (10) befindet, eine stehende Schallwelle ausbildet.

摘要： A method for manufacturing a clad material in which a core material is cast and skin materials are pressure-bonded thereon aims to prevent deterioration of adhesiveness of the core material and the skin materials while keeping sufficient cooling rate of the core material, prevent thickness variation and/or breakage of the skin materials during the manufacturing process, and keep the surface property of the cooling rolls constant. The method for manufacturing a clad material (11) includes the steps of continuously supplying molten metal (M) into a gap between a pair of cooling rollers (2a) (2b) to cast a core material, and cladding skin materials (10a) (10b) on both surfaces of the core material with hot rolling by continuously supplying the skin materials on peripheral surfaces of the cooling rollers so that the skin materials prevent direct contact between the cooling rollers and the molten metal, wherein the skin materials are supplied so as to come into contact with the peripheral surfaces of the cooling rollers, and wherein a contact distance (L1) from a contact starting point (P1) where the skin material begins to come into contact with the cooling roller to a meeting point (P2) where the skin material begins to come into contact with the molten metal is set to 100 times or more of a thickness (t1) of the skin material.
