Abstract

In an upsetting press for reducing the width of rolled material, especially the slab width in hot wide strip blooming trains with toolholders 2 arranged on both sides of the slab edge and receiving the pressing tool 1, a mounting device is proposed for the detachable mounting of the pressing tool 1 and the toolholder 2 which has at least one pretensionable tie bolt 3 with a hammer-shaped tie bolt head 5 held so that it can rotate in or on the toolholder 2, which tie bolt head engages in a recess 6 in the pressing tool 1 which is open on one side, essentially matches the tie bolt head 5 and supports this. <IMAGE>
