Abstract
A method and apparatus for performing forming operations on steels, metals, and alloys having low deformability and/or high resistance to deformation at room temperature, wherein the thickness of the stock material is small. In the method, stock material is heated by continuous rapid heating, to a temperature of at least 400.degree. C. and at most the AC-1 temperature of the alloy, and the heated material is subjected to a two-stage or multistage forming operation wherein the overall reduction in cross section is substantial. The apparatus includes a heating device of the electrical induction or direct contact type, followed by a temperature equalization and guide device and a multi-stand roll forming mill which may have cooling devices between each stand.
