    Abstract: Process and ultracompact plant for continuous production of hot rolled steel strip comprising an ingot mould (15) which produces a very thin slab at a speed between 4 and 16 m/min, wherein the thickness of the narrow sides is between 15 and 50 mm with a central swelling. Such slab has a core in which the steel is still liquid; it is run through a vertical pre-rolling device (16) which reduces the thickness of the slab, flattening it. The solidified slab can thus undergo a first light rolling process using a pinch roll (17) and, by forming a free curve, it moves to a horizontal position where it can undergo a second light rolling process by another pinch roll (22′). A heating process (if required) includes an inductor (50). A superficial descaling process and a series of reductions in a rolling mill made up of at least three stands (20′, 20″, 20′″) are provided maintaining a slab temperature along the train above the Ar3 recrystallization point. Downstream of the rolling mill, there is a conveyor (31) with cooling showers (32), flying shears (33) for cutting the strip to the required size, pinch rolls and at least two coilers (34) for forming coils of the hot rolled strip.

    Abstract: A machine makes nails having a star-shaped transverse cross-section by sequentially feeding conventional nails into a form roller station defined by a plurality of form rollers that are radially arrayed with respect to a centerline of the nails. Circumferentially spaced notches formed about the periphery of each form roller engage the heads of the conventional nails as the form rollers rotate and pull the nails into forming relation with the form rollers. The notches also prevent formation of the nail heads. A plurality of circumferentially spaced concavities formed in the form rollers prevents forming of the work-hardened points of the nails. The nails are sequentially delivered from a bowl feeder to an indexer that inverts the nails. A pair of rotatably mounted augers transfer the nails from the indexer to a nail-gripping device that holds each nail until its head is engaged by the nail-engaging notch in each of the form rollers. The form rollers are rotated by a gear train that begins with a ring gear rotated by a motor, and the gear train enables adjustment of the rotational phase of the form rollers so that they may be maintained in rotational phase with one another.

    Abstract: The invention relates to a method of producing a steel strip having a thickness of less than 10 mm by the casting of a steel strand in a cooled continuous ingot mould. After leaving the ingot mould and until the welding of the inner walls of the already solidified strand shell, the not yet thoroughly solidified steel strand is compressed, the thickness of the strand shell being reduced with a degree of deformation of >40%. FIG. 2 is intended for the Abstract.
