METHOD AND EQUIPMENT FOR FORMING SLAB

摘要

PURPOSE:To shorten the overall length of the forming equipment and to prevent the generation of a tongue by combining a flying thickness screw-down press with which a large rolling reduction is obtainable with a flying edging press and executing pressing in a thickness direction. CONSTITUTION:A slab sent in a line direction 1 is heated in a heating furnace 2 and the slab heated to a high temp. is pressed in the transverse direction by using the flying edging press 3. The thickness increase of the edged slab extends up to the transverse central part of the slab and, therefore, the slab has a doming drum shape in the sectional shape. This slab is then pressed in the thickness direction by using the flying thickness screw-down press 4. Since the large rolling reduction is obtainable with the thickness screw-down press 4, the slab pressed in the transverse direction to the drum shape in the transverse sectional shape can be made into a rectangular section by one time of the pressing in the thickness direction or a fewer times of the pressing. The overall length of the forming equipment is drastically shortened in this way.
