Abstract: A continuous casting and rolling line for casting, rolling, and otherwise preparing metal strip can produce distributable metal strip without requiring cold rolling or the use of a solution heat treatment line. A metal strip can be continuously cast from a continuous casting device and coiled into a metal coil, optionally after being subjected to post-casting quenching. This intermediate coil can be stored until ready for hot rolling. The as-cast metal strip can undergo reheating prior to hot rolling, either during coil storage or immediately prior to hot rolling. The heated metal strip can be cooled to a rolling temperature and hot rolled through one or more roll stands. The rolled metal strip can optionally be reheated and quenched prior to coiling for delivery. This final coiled metal strip can be of the desired gauge and have the desired physical characteristics for distribution to a manufacturing facility.

Abstract: Disclosed herein are systems and method for forming a final hollow body from a metal strip. A forming system may include a forming station, a joining station, an inline heater, and a hydroforming station. Forming the final hollow body from the metal strip may include receiving the metal strip at the forming station and bending the metal strip to a desired cross-section with the forming station and such that longitudinal edges of the metal strip are abutting. In some aspects, the forming station includes at least one roller. The method may include welding the abutting longitudinal edges together as a seam region via the joining station and to form an intermediate hollow body. The method may include heating the seam region of the intermediate hollow body with the inline heater and hydroforming the intermediate hollow body to the final hollow body with the hydroforming station.

Abstract: Systems and methods are described for roll-forming metal substrates. The metal substrates are subjected to induction heating during the roll-forming process by exposure to time-varying magnetic fields, such as by exposure to a rotating permanent magnet, or exposure to laser radiation from a laser source. Heating of the metal substrates allows improved formability or plasticity of the substrate in order to reduce or eliminate damage to the substrate during roll-forming to low bending radius to thickness ratios. Heating of the high-strength metal substrates can also function to temper the substrates and/or improve surface corrosion resistance and form high-strength end products with desirable properties.
