    • An apparatus is disclosed for receiving a continuous series of rings (16) of a hot rolled product (12) such as a rod from a rolling mill. The apparatus includes: a) a portable container (24) having: i) a vertically disposed cylindrical side wall (30) open at its upper and lower ends; ii) a base (32) at the lower end of the side wall configured to removably locate the container at a coil forming station (20); iii) a horizontal shelf (34) projecting inwardly from the interior of said side wall; and iv) a central core (38) supported by the shelf, the core being spaced inwardly from the interior of the side wall to define an annular chamber (42) therebetween, the shelf having access openings therein communicating with the chamber; b) an elevator platform (50) at the coil forming station, the elevator platform having support members (52) configured and arranged to pass through the access openings in the shelf; and c) means (56) for vertically adjusting the elevator platform to move the support members through the access openings in the shelf between raised operative positions at which the support members project into the chamber to support a coil therein by the receipt of the rings through the open upper end, and an inoperative position beneath the shelf, resulting in the coil being deposited on the shelf.

    • A method and apparatus for continuously hot rolling ferrous long products which employs a "post finishing" block of roll stands downstream from the finishing stands of the mill. Water boxes or other like cooling devices are preferably interposed between the last mill finishing stand and the postfinishing block. The post finishing block includes at least two reduction stands followed by at least two sizing stands. The reduction stands have an oval-round pass sequence, and the sizing stands have a round-round pass sequence. Clutches or other equivalent means are employed in the drive train to permit changes to be made between the interstand drive speed ratios of at least the reduction stands, and also between some or all of the remaining sizing stands. A fixed rolling schedule is provided for all roll stands in advance of the finishing stands. Thus, the finishing group is supplied with a first process section having a substantially constant cross sectional area and configuration. The first process section is passed through the finishing group and rolling occurs in either none, some, or all of the finishing roll stands, depending on the size of the desired end product. The product then continues through water cooling boxes to the post finishing block as a second process section. The interstand drive speed ratios of the roll stands in the post finishing block are appropriately adjusted to accommodate rolling of the second process section. The total reductions affected in the initial reduction stands of the post finishing block are well above 14%, thereby producing an increased energy level in the product sufficient to create a substantially uniform distribution of fine grains. Typically, such total initial reductions will be on the order of about 20-50%. Significantly lighter reductions on the order of 2-15% are taken in the final round-round pass sequences of the post finishing block to obtain the desired close sizing tolerances in the finished product. The time interval between the higher reduction affected in the oval-round pass sequence and the lighter reductions affected during sizing in the round-round pass sequence is such that the resulting grain size throughout the product cross section will not vary by more than 2, and in most cases by less than 1 ASTM grain size number.
