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.
Claims6
A sizing press for reducing the width of hot slabs of one of a low carbon steel and a stainless steel, comprising:
- a stack of main press dies of at least two types of caliber configurations;
- a die slider on which said main press dies are mounted;
- a die shift cylinder for selectively driving said die slider and said stack of main press dies in an up and down direction relative to said hot slabs to be reduced;
- a block mounted on said press to which said die slider and said die shift cylinder are attached, said block being reciprocately movable in a widthwise direction for reducing said hot slabs under pressure of said main dies;
- a changing platform car which reciprocately moves between a position above said sizing press and an off-line position of said sizing press for exchanging said die slider for a new die slider;
- a lifting device mounted on said changing platform car for lifting said die slider from said press to a level above said sizing press and for lowering said new die slider into said press;
- and
- a loading/unloading device associated with said press at said off-line position for exchanging die sliders on said changing platform car.
