Abstract: A method and apparatus of making coiled plate, sheet in coiled form or discrete plate. The apparatus includes a continuous strip caster forming a strand of intermediate thickness; a shear for cutting the strand into a slab of desired length; a slab table including a slab takeoff operable transverse of the conveyor table; a slab collection and storage area adjacent to the slab conveyor table adapted to receive slabs from the slab takeoff; one or two reheat furnaces having an entry inline with both the slab conveyor table and the slab collection and storage area for receiving slabs from either; a feed and run back table at the exit of one reheat furnace; a single or twin stand hot reversing mill for reducing the slab to a coiling thickness in a number of flat passes; and a pair of coiler furnaces located on opposite sides of the hot reversing mill.

Abstract: A method and apparatus of making coiled plate, sheet in coiled form or discrete plate. The apparatus is an intermediate thickness slab caster and inline hot strip and plate line. The apparatus includes a continuous strip caster selectively forming a single or a pair of parallel strands of between 3.5 inches (8.9 cm) and 5.5 inches (14 cm) thick, preferably 5 inches (12.

Abstract: A method and apparatus of making coiled plate, sheet in coiled form or discrete plate. The apparatus is an intermediate thickness slab caster and inline hot strip and plate line. The apparatus includes a continuous strip caster forming a strand of between about 3.5 and 5.5 inches thick; a shear for cutting the strand into a slab of desired length; a slab table including a slab takeoff operable transverse of the conveyor table; a slab collection and storage area adjacent to the slab conveyor table adapted to receive slab from the slab takeoff; a reheat furnace having an entry inline with both the slab conveyor table and the slab collection and storage area for receiving slabs from either; a feed and run back table at the exit of the reheat furnace; a hot reversing mill for reducing the slab to a thickness sufficient for coiling in a minimum number of flat passes; a pair of coiler furnaces located on opposite sides of the hot reversing mill; and a finishing line downstream of the pair of coiler furnaces.

Abstract: A pinch roll and shear combination for use in a mill, such as a reversing hot strip mill. The pinch roll and shear combination includes a stationary frame provided with a rotatably mounted lower roll and stationary lower blade adjacent the lower roll. A rectilinearly movable carriage is mounted on the frame with a piston for moving the carriage. An upper roll is rotatably mounted on the carriage and cooperates with the lower roll to form a pinch roll. An upper blade assembly is mounted on the carriage and cooperates with the lower blade to form a shear.

Abstract: A hot strip mill including an improved coiler furnace adapted to minimize heat losses and exposure of the roller table to extreme working conditions. The coiler furnace includes a mandrel which is mounted within a housing. An access opening is provided in the housing for allow for entry and exit of the stripper material being worked upon. A pivotable diverter is mounted on a pivot pin adjacent this opening and is shiftable between a closed position which substantially seals the housing closing of the access opening and an open position which extends into the pass line of the roller table of the hot strip mill to divert the strip being worked upon into the coiler furnace.

Abstract: The method of processing soft metal slabs to strip thickness on a processing line including providing a hot reversing mill having coiler furnaces on either side thereof along the processing line; heating the slab to a hot working temperature; passing the heated slab through the hot reversing mill at least one time to reduce the thickness thereof to form an intermediate product of a coilable thickness; coiling the intermediate product in one of the coiler furnaces; passing the intermediate product back and forth through said hot reversing mill and between the coiler furnaces to reduce the intermediate product to a product having a strip thickness; processing the product of strip thickness through a quench; and surface cleaning the quenched product. No subsequent hot rolling, hot milling, cold reduction or anneal takes place prior to forming the product of strip thickness.

Abstract: The method of controlling strip flatness on a hot strip mill which includes a hot reversing mill as a final reducing stand comprises reducing the thickness of the workpiece by passing it back and forth along a pass line through the hot reversing mill while reducing the roll gap on the mill after each successive pass. The strain developed during rolling is equalized by passing the workpiece through a shape processor having a plurality of upper and lower rolls capable of intermeshing along the pass line and located immediately downstream of the hot reversing mill. The equalizing of the strain through the shape processor occurs during selected intermittent passes and/or through the last pass through the reversing mill.

Abstract: A method of improving the productivity and yield of a reversing plate mill comprises installing coiler furnaces on the upstream and downstream sides of the mill. Thereafter, a supply of extra large slabs as well as a supply of pattern slabs for the mill are provided. The plate requirements for the next horizon period are analyzed and for each size plate, a decision is made (i) to process extra large size slabs, or (ii) to process pattern slabs, or (iii) a combination of both extra large and pattern slabs to supply the plate requirements. The slabs are then processed in accordance with the particular decision.
