Abstract

1480164 Making steel strip; forging T SENDZIMIR 1 July 1975 27672/75 Headings B3A and B3H A process for making hot-rolled metal strip in one of a plurality of widths from a slab of constant cross-section issuing from a slab caster on a planetary mill, which requires for its starting material a slab of lesser thickness, comprises reducing the thickness of the slab by subjecting it to the repeated action of a pair of opposed pressing tools 4, 4, reciprocable towards one another and at least one of which is pivotable and causing the or each pivotable tool to engage the slab in each cycle at a predetermined point in relation to the tool pivot axis, the tool being free to pivot so as to follow the advance of the slab therby creating a negligible forward pressure component and excluding any rearward component. A cast steel slab 1 is advanced by pinch rolls 2 and passed through the lights of edging tools 3 and the tools 4 into feed rolls 5 of the planetary mill. A U-frame 11 carrying the upper tool 4 and a lower frame 12 carrying the lower tool 4 are reciprocated by eccentrics (10), (10<SP>1</SP>) and (9), (9<SP>1</SP>), Fig. 2 (not shown), respectively mounted on a shaft 7 at 180 degrees to each other. A resilient connecting rod, which includes an air loaded cylinder with an adjustable stop, ensures that both tools 4 contact the slab while in a predetermined angular position with respect to the shaft 7. Once contact has been made. the frames 11, 12 are free to swing around the shaft so that their grip does not interfere with the travel of the slab, which must move at the speed imposed by the feed rolls 5. Edging tools 3 mounted on connecting rods (22), (22<SP>1</SP>), Fig. 3 (not shown), fulcrumed in pistons (21), (21<SP>1</SP>), are actuated by pump plungers 18, (18<SP>1</SP>), Fig. 2, actuated in turn by connecting rods 17, (17<SP>1</SP>), in co-operation with cranks 16, (16<SP>1</SP>) mounted on the ends of the shaft 7. In an alternative embodiment the tools are driven by a pair of eccentric shafts (7), (7<SP>1</SP>), Figs. 4, 4a (not shown). The tools are staggered in the direction of travel of the slab and they are opposed by stationary anvils. The shafts (7), (7<SP>1</SP>) may be driven by elliptical gearing, Fig. 5 (not shown), so that they are driven at a low angular speed when the tools contact the slab and at a higher speed when out of contact with it. To produce a wider slab than that emerging from the caster, it is passed through a pair of edging presses 63, Fig. 8, and through reducing presses 64, 64<SP>1</SP>, arranged at an angle to the direction of travel of the slab. The press 64<SP>1</SP> is mounted on a turntable 55 which is slidable along rails 56. To obtain a larger increase in slab width, the press 64 is turned to a greater obliquity relative to the slab travel, Fig. 10 (not shown) and its tools are set to produce a wedge-shaped cross-section of the slab so as to cause it to bend in a horizontal plane and be correctly aligned for entry into the press 64<SP>1</SP>.
