摘要:
A furnace for heating steel plates includes a plurality of horizontal furnace levels in superimposed disposition. Each furnace level is constructed for acceptance of at least one steel plate and includes a transport mechanism for moving the at least one steel plate during a heating process.
摘要:
A structural motor-vehicle element is made by hot-shaping and press-hardening a steel workpiece into the element and thereafter heating the hot-shaped and press-hardened workpiece to between 320° C. and 400° C. The steel workpiece constitutes in weight percent, Carbon (C)0.18% to 0.3% Silicon (Si)0.1% to 0.7% Manganese (Mn)1.0% to 2.5% Phosphorus (P)max. 0.025% Chromium (Cr)up to 0.8% Molybdenum (Mo)up to 0.5% Sulfur (S)max. 0.01% Titanium (Ti)0.02% to 0.05% Boron (B)0.002% to 0.005% Aluminum (Al)0.01% to 0.06% the rest iron including impurities caused by the smelting process.

摘要:
A dashboard for a motor vehicle includes a support beam extending between windshield pillars of a motor vehicle body, and an active arrangement which interacts with the support beam for vibration damping. The active arrangement includes plural actuators which are disposed on the support beam and a controller which is operatively connected to the actuators. Further provided is an alert system for recognizing a fatigue state of a driver, with the actuators operatively connected to the alert system via the controller.

摘要:
In a method of applying a firmly adhering metallic coating onto a profiled structure of steel sheet, a profiled structure of steel sheet is fogged in with metal powder in a treatment chamber. The metal powder is deposited electrostatically across the surface of the profiled structure. The profiled structure is then subjected to a heat treatment for realizing a coating as a consequence of a diffusion process between the steel sheet and the metal powder. Subsequently, the profiled structure is cooled down.
