摘要： An apparatus and a method for the treatment of a flat steel product, taking place in throughput. The apparatus includes an indirectly heated annealing furnace chamber, a conveyor device for continuously conveying the flat steel product over a conveyor path leading from an entry to an exit of the annealing furnace chamber, and nozzle arrangements for feeding atmosphere gas, which is reactive in relation to the flat steel product, into the annealing furnace chamber. A controlled treatment of the flat steel product includes a first nozzle arrangement, from which a gas jet induces a first gas flow towards the entry of the annealing furnace chamber and sweeping over the surface of flat steel product to be treated. A second nozzle arrangement includes a gas jet which induces a second gas flow directed towards the exit of the annealing furnace chamber and sweeping over the surface of flat steel product.

摘要： The invention relates to a coated steel sheet or strip with a ground coating made of steel, onto at least one upper side of which a coating is applied by hot-dip galvanizing, the coating being formed from a melt consisting of 0.05-0.30% by weight Al and 0.2-2.0% by weight Mg, the remainder being zinc and unavoidable impurities, and, with a coating thickness of a maximum of 3.5 μm on each side and a coating weight of a maximum 25 g/m2 on each side, guarantees that the steel sheet, in the salt spray mist test carried out in accordance with DIN 50021-SS, shows the first formation of red rust at the earliest after 250 hours. With such a sheet or strip, a flat steel product is provided which possesses an optimum combination of high corrosion resistance and optimum weldability and which is particularly well-suited for use as a material for motor vehicle chassis construction or for the construction of domestic appliances.

摘要： The invention relates to the field of materials science and to a device for reducing pressure in cavities in media at higher temperatures, such as those devices which can be used for devices for hot-dip coating metal materials in the metal processing industry for example. The aim of the invention is to provide a device by means of which pressure can be reduced in the cavity of the hollow bodies in a reliable and controlled manner and simultaneously the penetration of the media can be delayed or completely prevented at the higher temperatures. This is achieved by a device for reducing pressure in hollow bodies in media at higher temperatures, wherein at least one opening to the cavity of the hollow body is provided in hollow body regions which are not used for the intended application, said opening being closed from the medium surrounding the hollow body by at least one component made of a gas-permeable metal or ceramic material.
