Abstract
PURPOSE: To prevent the generation of cracks, and to continuously form the titled steel shape, by rolling an ingot into a flat billet in a hot processing section kept at prescribed temperatures, by forming the flat billet into a strip through a leveling process, by froming this strip into a prescribed shape and size in a cold processing section kept at prescribed temperatures, and by painting the surface of the product shape in a remaining heat processing section.
CONSTITUTION: An ingot 2 obtained by an open-hearth furnace or an electric furnace is preliminarily rolled into a flat billet 2a in a hot processing section A kept at ≥400°C; the scales flating on the surface of this billet 2a are primarily removed by a descaler 4. The billet 2a is then fed to a three-stage leveling mill 5 and receives a leveling process; hereby, the side plane and front plane of the billet 2a are straightened to a prescribed size. This straightened strip is roll-formed into a prescribed shape in a cold processing section B kept at 400W200°C; thus formed shape is then cut into a prescribed size. The scales are then secondarily removed by a descaler 8 and the strip 2b is painted for finishing a product 2c in a remaining heat processing section C.
