    Abstract: The aim of the invention is to improve the surface quality of slabs (5) having a thickness of up to 400 mm, that are produced in a continuous process from continuous casting to hot-rolling, for example according to the CSP method, by means of an in-line surface treatment. To this end, a defined surface layer of the slab (5) with a layer thickness per slab side of up to 4 mm is oxidised in a targeted manner by an oxidising flame or an oxidising gas mixture applied to the upper and lower sides of the slab (5) by means of an oxidation device containing nozzles or a similar device, said layer being removed later on during the process. The oxidation product on the slab surface can be solid or liquid.

    Abstract: A method and apparatus for the descaling of metal surfaces without the use of caustic substances is provided. The apparatus includes a first and second blast heads containing nozzles that spray high velocity jets of media at a scale covered continuous sheet of steel. The continuous sheet of steel is advanced into an abrading station containing a pair of brush assemblies that include stainless steel bristled brushes. The stainless steel brushes engage the surface of the sheet of steel and abrade away the cracked scale, leaving a surface clean of scale. The surface produced is pH neutral and therefore resists additional corrosion and does not require oil coatings, or other protective treatments. Eliminating these steps makes for a faster, more robust process and saves considerable cost.

    Abstract: Martensitic stainless steel whose steel composition is restricted within a specific range for each element is provided. The scale layer formed on the surface of the base material consists of an inner layer scale mainly including FeCr2O4 and an outer layer scale having a thickness of not more than 20 μm, which outer layer is deposited on the inner layer scale at a surface coverage of not less than 1% and not more than 15%. The application of rust preventive oil onto the surface of the steel ensures an excellent weather resistance during a long term, and therefore a martensitic stainless steel forming no rust either in the outdoor depository or in the indoor depository can be provided. The steel can be used to manufacture, not only steel pipes, but also steel plates, steel rods and others in a wide application field.
