APPARATUS FOR TREATING STEEL.
Application filed February This invention relates to apparatus for treating metal and more particularly for heat treating rolled steel without the necessity of reheating, and has for its object the provision of apparatus in which rolled metal may be quenched to increase the tensile strength and elastic limit of the metal immediately after leaving the rolls and without reheating.
Another object is to provide apparatus having the novel construction, design and combination of parts hereinafter described and illustrated in the accompanying drawings.
In the drawings Figure 1 is a'plan view of the apparatus embodying my invention.
Figure 2 is a side elevation thereof.
Figure 3 is a sectional view taken on the line III-III of Figure 2.
Figure 4 islan enlar ed fragmentary detail plan of a portion 0 the trough.
Figures 5 and 6 are sectional views on the lines VV and VL-VI, respectively, of Figure 4.
Referring more particularly to the drawings, the numeral 2 designates the finishing stand of rolls of a rolling mill. A trough A, composed of sections 3 bolted together and supported on stands 4, extends from the rolls 2 toward the cooling bed. Each of the sections of trou h is provided with a inrality of spaced internal shoulders or ri s 5 which are beveled rearwardly or toward the rolls as at 6,' so as' not to impede the passage of metal through the trough.
A water su ply main extends parallel with the troug and isprovidedwith branch conduits 8 connecting with each of the I troughsections. ;Each of the conduits 8 is provided with a valve 9 for'co'ntroll1ng the feed of waterto the trough.
A drain trough or conduit 10 is mounted under the trough A and supported on the ,stands 4. An overflow-pipe 11 extends from a point adjacent the upper edge of each of the trough sections downwardly into'the drain trough 10 to prevent the overflowing of the trhugh, and a pluralitioof drain conduits 12' extend from the ttom of the trough sections downwardly into the drain trough 10. The drain conduits 12 are provided with valves 14 to control the flow of water therethrough.

toward the rolls and has an extension 15 whichextends into the scale pit 16 of the rolls, which pit is provided with the usual drain (not shown) connecting with a sewer or other point of disposal.
A pair of combined dam and guide members B are adapted to be mounted in the trough A. The members B are castings adapted to fit between any two of the, ribs 5 of the trough and provlded with a guide opening 17 therethrough, the top wall 18 of the casting being inclined downwardly so as to guide or force the metal being treated downwardly along the bottom of the trough. The forward or exit end of the opening 17 is adapted to be normally closed by a self closing hinged dam or closure 19.
The members B are adapted to be secured in position by clamping yokes 20 vhaving their ends secured in bosses 21 on the sides of the trough and having a cooperating key 22 and wedge 23 mounted between the clamping yoke and member B.
One of the combined uide and dam members B is adapted to be ocated at the enteriigend of the trough, and the other member is point along the length of the trough which will provide a suflicient body of water between the members to quench the metal.
In '0 ration, the metal, designated by the letter after leaving the finishing stand of rolls 2, passes through the guide B at the rear or entering end of the trough, and entersthe body of water in the portion of trough between this guide'and the second or forward guide B. While passing through the body of water the metal is quenched and it then passes out through the forward guide B and onto a cooling bed orother lace of disposal (not shown). The distance etween the combined dam and guide members, or the length of the body of water in the trough, can be adjusted at will to suit the quenching time required to give .the bar the necessary heat treatment by changing the position of the dam and guide members B. a
In order to maintain the body of water adapted to be located at any desired I betweenthe two dam and guide members B level, a1l the valves 9 of the branch pipes between the two members are opened, while-the valves!) on the remaining inlet pipes are closed, and the valves 14 in the drain pi s 12 between the We mem e B are clo e f The valves-14; m
at the. proper water inlet or the remaining drain pipes 12 beyond the members B, are opened to provide for the escape of the water flowing out of the guide openings 17 as the metal passes through the members B.
The apparatus above described, provides for the heat treating or quenching of metal after rolling without reheating or rehandling and also provides an apparatus capable of adjustment for treating a wide range of sizes of metal rods or bars.
