Abstract
In a sizing press for reducing by pressure width of hot slabs of both a low carbon steel and a stainless steel, the reduction by pressure of width is performed quickly without replacing the dies each time. Two or more types of dies having caliber configurations for respectively reducing the width at least of a low carbon steel and a stainless steel are disposed in layers and are retained in a manner capable of being displaced in an up and down direction. They may be replaced as a block with another block of stacked dies.
