Metallic tubular products with enhanced collapse resistance

Metallic tubular products having improved collapse resistance are disclosed. The metallic tubular products are produced by compressive forming processes. The method comprises identifying the types of stress that can be applied in order to change the residual stress profile of metallic tubular products, such as those that have completed a straightening process, and results in a residual stress profile that improves collapse resistance. The metallic tubular products are subjected to radial compression processing to control the residual stress profile and to enhance collapse resistance. The radial compression process may be used after the tubular product has been subjected to a straightening process.

Reduction of surface defects during finish rolling of hot strip

The invention relates to a finishing train for finish rolling hot strip. It is the object of the invention to modify an existing finishing train in such a way that the surface quality of the hot strip produced is improved without, however, significantly increasing the use of energy during production. This is intended to enable the thin hot strip produced to be used even for applications with high demands on surface quality. This object is achieved by a cleaning nozzle which cleans the upper side of the exit table, thus ensuring that scale and/or rolling dust are/is removed from the exit table.

Process for forming wrought structures using cold spray

A process and apparatus of producing a product having a wrought structure. The process comprises the step of: applying heat and a compressive load simultaneously to an application area of a cold spray deposition preform to transform the comprising consolidated particle structure into a wrought structure, the compressive load being applied laterally to the application area. The application of compressive load and heat to the application area raises the temperature of the material of the preform in the application area to between the recrystallisation temperature and the melting point of the material.

IMPROVED OPERATION OF AN INDUCTION FURNACE

Induction furnace, method for operating, control program, and control device for an inducation furnace for heating planar rolled stock material made of metal. The rolled stock passes through the induction furnace in a longitudinal direction and extends transversely thereto from a first to a second rolled stock edge. The induction furnace has a plurality of module pairs which, viewed in the longitudinal direction, follow one another sequentially and each have a first and a second induction module. The induction modules, as viewed in the transverse direction, are positioned at a respective initial position, so that the first induction modules are arranged offset towards the first rolled stock edge and the second induction modules are arranged offset towards the second rolled stock edge. Induction modules are supplied with electrical power via respective power supply devices. A respective electrical target variable is defined for each induction module.
