Abstract
1292331 Rolling mills UNITED ENG & FOUNDRY CO 17 Dec 1969 [3 Jan 1969] 585/69 Heading B3M A rolling mill is provided with work roll chocks 15 and 16 connected together by bars 51, the bars facilitating removal of the work rolls 19 and 21 as a unit. Each bar is fixed to an upper chock and incorporates a slot 52 which is engaged by a pin 53 attached to a lower chock, the pin- and-slot connection allowing relative vertical movement between the chocks. To change the work rolls in a 4-high stand, the upper backing roll chocks 23 are raised by a balancing cylinder, thus causing rods 39 and 41 to be lifted. The rods extend through extensions 13 and 14 of the mill housings and carry rails 46 and 47 at their ends. The rails are thereby raised into contact with wheels 50 on the bars 51, and the chocks of both work rolls are lifted to the position shown. The work rolls can then be removed from the stand along the rails.
