United States Patent APPARATUS FQR .QUENCHING AND REELING RODS John D. Popp, Belle Vernon, Pa, as'signdr to United tates Steel Corporation, a' corporation of: New

ersey Application" September 15, 1955, Serial No. 534,576 2 Claims. Cl. 134- 46) This invention relates to apparatus for quenching and reeling rods and more particularly for quenching hot rolled rods with water as they emerge from the last pass of the mill prior to being reeled into bundles. Apparatus suitable for this puropose is shown in the patent to Strachan No. 2,658,012, dated November 3, 1953. However, that apparatus utilizes an electric eye to operate a valve for supplying water to the rod and I have found that the electric eye becomes dirty in use with the result that the cooling water is not supplied to the rod in some instances. 7

It is therefore an object of my invention to provide apparatus for reeling hot rolled rods that will overcome the above mentioned difiiculties.

This and other objects will be more apparent after reterring to the following description and attached drawings, in which:

Figure l is a schematic view of the apparatus of my invention;

Figure 2 is an enlarged view, partly in section, of a detail of Figure 1;

Figure 3 is a sectional view taken on the line IIIIII of Figure 2;

Figure 4 is an enlarged view of a detail of Figure 1;

Figure 5 is a view taken on the line V-V of Figure 4;

Figure 6 is a view taken on the line VIVI of Figure 4;

Figure 7 is a view, similar to Figure 4, showing a modification thereof; and

Figure 8 is a view taken on the line VIIl-VIII of Figure 7.

Referring more particularly to the drawings, reference numeral 2 indicates the last roll stand of a hot rod mill. Rod R passes through the roll stand 2 into the bell mouth 4 of a guide pipe 6 and then into a bell mouth 8 leading into the water cooler box 10. The water quenching means consists of a number of sectional elements 12 within the box 10. As shown in Figures 2 and 3, each of the elements 12 is made up of concentric tubes 14 and 16 having a space 18 therebetween. The inner tube 14 is provided with a plurality of holes 20 therein drilled at an angle of 45 to a radius through the wall thereof in order to allow water to enter the inner portion 22 of the pipe 14 through which the rod R passes. Water is delivered into the space 18 from a header 24 through branch pipes 26. A pipe 28 connects the header 24 to the main water line. The flow of the water into the pipe 28 is manually controlled by means of valve 30 and is automatically controlled by means of a quick acting water valve 32 which is operated by a solenoid 34. The

solenoid 34 is in an electric circuit including a power source L1 and L2 and a switch 36. A guide 38 is arranged between two of the sections 12. The guide 38 consists of a bell mouth 40 and an extension 42 having a cover 44 pivotally mounted on a pin 46. The lower end of cover 44 is in line with the path of movement of rod R. An arm 48 on cover 44 extends rearwardly from the pin 46 and has a counterweight 50 adjustably 2,880,739 Patented Apr. 7, 1959 "ice mounted thereon. I bracket 52 secured to the water cooler box 10. A. lever arm 54 pivoted intermediate its ends has one end. con: nected to switch contact 360 and the other end in line with a rod 56. A spring 58 surrounds the rod 56 with one end abutting bracket 52 and the other end abutting a shoulder 60 on the rod 56. An externally threaded rod 62 is threaded into the lower end of rod 56. The lower end of rod 62 has bifurcations 64 with a portion 66 of cover 44 extending upwardly therebetween and pivotally connected thereto by means of pin 68.

In order to provide for manual operation, a by-pass 70 is provided around the valve 32. A manually oper= ated valve 72 is provided in the by-pass 70. The rod R passes from the cooling box 10 through a pipe 74 to the reel 76. The reel 76 has a housing 78 within which are guide pins 80 mounted on a member 82 which is rotated by means of gearing 84.

The operation of the device is as follows:

When the rod R contacts the concave bottom end of cover 44 the cover 44 moves upwardly around its pivot 46 to the broken line position shown in Figure 4. Very little force is necessary for this purpose because of the counterweight 50. This pivoted movement raises rods 56 and 62 causing lever arm 54 to move to the broken line position of Figure 5, thus closing contacts 36C of switch 36 to complete a circuit to energize solenoid 34 to open quick acting valve 32. This starts the flow of water into the header 24, thence into the space 18 and then through the holes 20 to spray the rod passing therethrough. The uncooled forward end portion of the rod will readily wrap itself about the pins 80 of the reeler, thus eliminating cobbling. Once the rod is securely wrapped around the pins 80 the quenched rod will follow without damage. After the rod R passes from under the cover 44 the spring 58 will bias the rods 56 and 62 downwardly to return the cover to its normal position, thus opening contacts 36C so that the valve 32 will close and water will drain from the cooling sections 12 into the cooling box 10 and hence through a drain pipe 86. The apparatus Will then be ready to receive the next rod.

In the embodiment of Figures 7 and 8 a guide 88 is provided which, in place of a cover, has a portion 90 normally in line with the path of travel of the rod R. The guide 88, including the portion 90, is pivotally mounted for movement with pin 92. A counterweight 94 is mounted on the end of an arm 96 which like guide 88 is fixed for rotation with pin 92. An arm 98 attached to guide 88 is pivotally connected to a rod 100 corresponding to rod 62. The rod 100 is threaded into rod 56. The construction and operation of this embodiment is otherwise the same as that of Figures 4, 5 and 6.

While two embodiments of my invention have been shown and described it will be apparent that other adaptations and modifications may be made without departing from the scope of the following claims.

I claim:
