Continuous casting equipment includes a casting product reduction apparatus and a casting product drawing apparatus, the casting product reduction apparatus including a pair of casting product reduction rolls that sandwich and apply pressure to a casting product and being configured to apply reduction to the casting product, the casting product drawing apparatus being provided in a following stage of the casting product reduction apparatus and configured to sandwich and draw the casting product with a pair of casting product drawing rolls. At least one of the pair of casting product reduction rolls includes a large-diameter part that projects radially outward in an axial-direction center region and applies pressure to a width-direction center region of the casting product. The casting product that is subjected to reduction by the casting product reduction apparatus has a depressed part corresponding to the large-diameter part. At least one of the pair of casting product drawing rolls of the casting product drawing apparatus includes a depressed part supporting part that contacts with and supports the depressed part, and is driven by a driving mechanism. An axial-direction length L.sub.2 of the depressed part supporting part and an axial-direction length L.sub.1 of the large-diameter part of the casting product reduction roll satisfy 0.5×L.sub.1≦L.sub.2<L.sub.1.

A spacer for adjusting the width between rollers of roller tooling for machines operable to form metal products has an annular male member with lateral bosses and an annular female member having different depth pockets accommodating the bosses to adjust the combined width of the male and female members.

An exterior décor panel for a home appliance includes a metal sheet having a first surface and a second surface opposite the first surface. The metal sheet includes a first patterned portion having successive recesses formed in the first surface, where each of the successive recesses have a prescribed depth, and a second patterned portion having successive protrusions formed at the second surface, where the successive protrusions correspond to the successive recesses. The successive recesses are formed by applying a force to the first surface, thereby transferring the force to the second surface to form the successive protrusions.

In the present there is presented a method to manufacture multimaterial rolls, comprising method to produce base material containing part of the roll, joining of special material containing part for that, hot working at least part of the length of the roll ingot containing base material and special material, —so that at least requested roll ingot length and diameter are achieved as well as final treatment of the roll ingot—to manufacture finished roll. This method enables manufacture of large rolls, for example having length more than 3 meters as one integrated component without welding or mechanical joint—so, that in the working surfaces of the rolls is used steel with high amount of alloying elements and carbide forming alloying elements.

Described herein is a method for rolling metal sheets of variable thickness. The method makes it possible to impress, during rolling, any distribution of areas of increased thickness within a figure corresponding to the plane development of a motor-vehicle component prior to the pressing operation. Impression of the desired distribution of areas of increased thickness envisages simultaneous impression, during rolling, of a further distribution of areas of increased thickness, or compensation areas.

In the present invention, when synchronization is lost due to backlash, and deviation between the rotational phases of a first processing roll and a second processing roll occurs, deviation between the rotational phases of dummy rotating bodies also occurs, and dummy blade parts of the dummy rotating bodies interfere with each other before blade parts of cutting blades of the first processing roll and the second processing roll (40) interfere with each other. Thus, interference between the blade parts is prevented.
