PLATE MANUFACTURING METHOD COMPRISING PROCESSES OF FORGING WIDTH AND THICKNESS

摘要

PURPOSE: A thick plate manufacturing method comprising width and thickness forging processes is provided to reduce a difference in material and dimension of final products by minimizing the temperature deflection of a material extracted from a furnace. CONSTITUTION: A thick plate manufacturing method comprises the steps of heating a slab(1) is heated in a furnace(2), transferring the heated slab to a forging machine arranged behind the furnace, rotating the slab 90° in a specific direction, carrying out width forging, rotating the slab 90° in the opposite direction, carrying out thickness forging until the target thickness, and carrying out rolling the slab through a horizontal mill.
