Abstract: The mill comprises essentially a roughing train having a reversing roughing stand or stands and a finishing train having a reversing finishing stand or in-line finishing stands, the roughing and finishing trains being disposed with pass lines parallel to each other and at different elevations, the work in the roughing train progressing in the opposite direction from the work in the finishing train. The roughing train for strip and light plate is provided with a hot upcoiler at each end positioned above the table so that slabs and breakdowns pass beneath them, but adapted to coil and payout strip of coiling gauge. The delivery end of the roughing train is laterally opposite the entry end of the finishing train and separate mechanisms are provided for transferring coils and plate broadside from roughing train to finishing train.

Abstract: Coils of hot strip from a hot strip mill downcoiler are transferred broadside and set down with the coil eye horizontal on a walking beam conveyor. The conveyor comprises elongated transfer members pivoted at their lower end below the path of coil travel which swing toward and away from each other. Each transfer member has a coil-supporting platform on its upper end and coils are passed from one transfer member to the next when they approach each other, both at the intersections of their arcuate paths and at a point in each arcuate path intermediate those intersections, so that each coil is rotated about its axis during travel, but without rolling.

Abstract: A frame carrying one or more transducers is inserted between the work rolls of a mill stand with the transducers positioned parallel to the roll axis. The outputs of the transducers are connected to a display device which when load is applied to the rolls displays the several output signals side-by-side so that variation in loading lengthwise of the rolls is made visible. The outputs of the transducers may also be interconnected with automatic gauge and crown control circuits so as to calibrate those circuits.

Abstract: In a four-high mill stand separate transducer means are provided for measuring gauge in the bite of the work rolls and for measuring the inclination of work roll axis to the horizontal. Means are provided for generating a gauge command signal proportional to the work gauge and a crown command signal proportional to the desired work roll crown. The gauge and gauge command signals are added algebraically and applied to control the roll pressure producing means in the roll stand, and the crown, crown command and the gauge signals are added algebraically and applied to control the work roll bending means so that changes in the roll bending force do not change gauge, and the gauge and flatness of the rolled product are automatically held constant. A roll crown measuring transducer for high lift mills is also disclosed.

Abstract: The apparatus comprises a deflector roll over which the strip travels positioned above a downcoiler, an endless belt traveling just above the strip over the deflector roll, and two movable persuader rolls positioned within the belt loop. One roll is positioned beyond the deflector roll and, when depressed, wraps the lower flight of the belt and the leading end of the strip around an arc of the deflector roll so as to direct the strip end into the coiler entry. The other roll is positioned before the deflector roll and, when depressed, wraps the lower flight of the belt and the strip end around an arc of the persuader roll and up over the deflector roll so as to direct the strip end over the coiler entry.

Abstract: A mill stand for a four-mill has a short-stroke hydraulic rolling pressure cylinder at the top of each housing. Variations in size of back-up rolls are taken up at the top of the mill by a series of graduated filler blocks positioned around a quadrant so as to form a circular staircase. The staircase is rotated about a vertical axis to bring the desired step between cylinder and roll chock. The lower roll set rests on straight staircases which are moved transversely of the housings on the conventional roll sled. Between the bottom of the sled and the bottom of each housing is a low-angle wedge positioned to raise the lower roll set an amount equal to one step of the staircase. The stand is aligned to the strip pass line by operation of the rolling pressure cylinders.

Abstract: A method of making a compound roll of the type having a shell portion of a material that has a high hardness and wear resistance and a core portion forming the center core and neck sections of a material that has a low alloy content and a relatively low hardness so as to be highly resistant to breakage, which method comprises the steps of precasting the shell portion in the form of a hollow cylinder having the desired external and thickness dimensions, setting the shell portion on top of a neck forming mold section with the longitudinal axes of the shell portion and the mold section extending vertically, positioning an electrode of an electro-slag melting unit within the interior of the shell portion and the neck mold section, the electrode being made of material which in the remelted and subsequent resolidified condition will have the desired properties for the center core and neck sections, and passing electric current through the electrode to cause melting thereof to progressively fill the mold section and
