Abstract

In the process and equipment for deformation of steels, metals and alloy of low deformability and/or deformation resistance at room temperature from raw material of small thickness, the raw material is heated, preferably by continuous rapid heating, to a temperature of at least 400 DEG C and at most up to the AC1 temperature of the alloy, and a two-stage or multi-stage deformation with an altogether large reduction in cross-section is carried out. <IMAGE>
