"APPARATUS FOR RECEIVING A CONTINUOUS SERIES OF RINGS OF A HOT ROLLED PRODUCT"

Abstract

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

The present invention relates to an apparatus for receiving a continuous series of rings of a hot rolled product. BACKGROUND OF THE INVENTION 1- Field of the Invention This invention relates generally to rolling mills producing hot rolled steel products such as bars, rods and the like, and is concerned in particular to an improvement in the retarded cooling of such products in insulated containers commonly referred to as "pots". 2. Description of the Prior Art It is known to form hot rolled steel products such as bars, rods and the like into helical ring formulations which are accumulated in coil form in insulated pots. The difficulty with such arrangements is that the vertical distance the rings travel as they descend into the pots varies considerably from the beginning to the end of a coil forming cycle. This varying drop distance adversely affects uniformity of ring distribution and density from the bottom to the top of the coil, thus contributing to coil instability while also disadvantageous^ increasing coil size. The primary objective of the present invention is the provision of an improved pot and associated adjustable coil support which operate in concert to maintain the top of the coil being formed in the pot at an optimum substantially constant height. By doing so, ring density and distribution is optimized and maintained substantially constant from the bottom to the top of the coil, which in turn minimizes coil size while maximizing coil stability. These and other objectives and advantages of the present invention will now be described in greater detail with reference to the accompanying drawings, wherein: Accordingly, there is provided apparatus for receiving a continuous series of rings of a hot rolled product, said apparatus comprising: a) a portable container having: i) a vertically disposed cylindrical side wall open at its upper and lower ends; ii) a base at the lower end of said side wall configured to removably locate said container at a coil forming station; iii) a horizontal shelf projecting inwardly from the interior of said side wall; and iv) a central core supported by said shelf, said core being spaced inwardly from the interior of said side wall to define an annular chamber therebetween, said shelf having access openings therein communicating with said chamber; characterized in that said apparatus comprises: b) an elevator platform at said coil forming station; said platform having support members configured and arranged to pass through the access openings in said shelf; said elevator platform being vertically adjustable to move said support members through the access openings in said shelf between raised operative positions at which said support members project into said chamber to directly support a coil being formed therein by the receipt of said rings through said open upper end, and an inoperative position beneath said shelf, resulting in the direct support of said coil being transferred from said support means to said shelf. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a diagrammatic illustration of the delivery end of a rod mill; Figure 2 is a vertical sectional view through the coil forming station shown in Figure 1, with the elevator platform fully retracted below the level of the roller table; Figure 3 is a horizontal sectional view taken along line 3-3 of Figure 2; Figure 4 is a view similar to Figure 2 showing the elevator platform in a raised position during a coil forming operation; Figure 5 is another view similar to Figure 2 showing a fully formed coil contained in the pot with the insulated bottom and top covers in place; and Figure 6 is a diagrammatic plan view of the roller table at the reforming station. DETAILED DESCRIPTION OF PREFERRED EMBODIMENT Referring initially to Figure 1, the delivery end of a rolling mill is shown comprising a pinch roll unit 10 arranged to direct a hot rolled rod 12 or other like product into an inclined laying head 14 which forms the product into a continuous helical series of rings 16. The rings WE CLAIM : Apparatus for receiving a continuous series of rings (16) of a hot rolled product (12), said apparatus comprising: 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 said side wall configured to removably locate said 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 said shelf, said core being spaced inwardly from the interior of said side wall to define an annular chamber (42) therebetween, said shelf having access openings therein communicating with said chamber; characterized in that said apparatus comprises: b) an elevator platform (50) at said coil forming station; said platform having support members (52) configured and arranged to pass through the access openings in said shelf; said elevator platform being vertically adjustable to move said support members through the access openings in said shelf between raised operative positions at which said support members project into said chamber to directly support a coil being formed therein by the receipt of said rings through said open upper end, and an inoperative position beneath said shelf, resulting in the direct support of said coil being transferred from said support means to said shelf. 2. Apparatus as claimed in claim 1, wherein said shelf is comprised of circumferentially spaced segments (34) defining said access openings therebetween. 3. Apparatus as claimed in claim 1 or 2, wherein said core has mutually spaced ribs (36) supported by and extending vertically from said shelf segments. 4. Apparatus as claimed in claim 3, wherein said ribs are interconnected at their upper ends by a cap (40).
