MILL LAYOUT 6 Sheets-Sheet 6 Filed NOV. 13, 1962 United States Patent F The present invention relates to mill layouts for metal rolling mills.
A purpose of the invention is to increase the flexibility in operating a metal rolling mill.
A further purpose is to permit installation of the equipment of a metal rolling mill in stages, so that a reasonable degree of utility can be obtained with a minimum of equipment at the beginning and greater utility can be se Patented June 8, 1965 2 the portion of the mill of'the second form to the right of that shown in FIGURE 2' in the second set of drawings.
FIGURE 3 is a fragmentary plan mill layout showing the third form ,of installation of the mill of the invention,

cured with a minimum of additional equipment and employing double or conjoint use of as much ofthe equipment as possible.
A further purpose is to reduce the time in changing the rolls when changing from one product to another in metal rolling mills. j
A further purpose is to provide a roughing mill which discharges to a first mill table in line with the roughing mill, which in turn discharges toa continuous mill in prolongation of the first mill table, which in turn feedsthe inlet to a looping finishing mill which has-a finishing stand in line with and feedingito' a second mill table which connectsto a cooling bed, andthento provide a lateral transfer from the first mill table to feed an intermediate .roll stand which is in line with the finishing stand of the looping finishing mill and also'in line with the second mill table.
A further purpose is to provide a second roughing mill stand which will cooperate with the lateral transfer and the intermediate mill stand. i
A further purpose is to employ an intermediate mill which is larger than the finishing stand of the looping finishing mill and to replace the finishing stand of the looping finishing mill with a larger mill stand at the same position.
A further purpose is to use a continuous finishing mill which has both a horizontal mill stand and a vertical edger. a A further purpose is to make one or more repeaters and guides of the looping finishing mill slide out of the way to permit the stock from the continuousfinishing millto enter the finishing stand of the looping finishing mill.
Further purposes appear in the specification and in the claims. I r i a In the drawings I have chosen to illustrate one only of the numerous embodiments in which the invention may appear, selecting the form shown from the standpoints of convenience in illustration, satisfactory operation and clear demonstration of the principles involved.
FIGURES 1 and 1a comprise a first set of drawings,
FIGURE 32: is a plan mill layout showing the third I 1 form of the installation of the mill equipment, and illustrating the portion ofthe equipment in the center of the third set of drawings, FIGURE 311 being to the right of FIGURE 3. t
FIGURE 3b is a plan mill layout showing the third form of installation of the mill equipment, the portion shown being to the right of that illustrated in FIGURE 3a in the third set of drawings.
FIGURE 4 is a plan view showing an alternate layout for the looping finishing mill.
Because of the large capital invested, many rolling mills find it diflicult to expand to produce a diversified product line. Many of the existing mill layouts are objectionable because the layouts are not flexible as to the production of difierent types of rolled stock. One of'the advantages of the invention is to give a wide diversity of types of stock which can be produced.
Also many of theprior art rolling mills are not effective 1 fromthe standpoint of utilization of mill equipment when changing fromone type of product to another. In such prior art mills a large proportion of thetotal equipment is inactive when a limited number of productlines are beingproduced. The present invention is concerned particularly with making double or conjoint use of equipment wherever possible. I j V In some of the prior art mill layouts, it is necessary to stop all operation when changing rolls or adjusting guides.
, One of the advantages of the present mill layout is that a substantial amount of roll changing or guide changing can be accomplished while bypassing the mill stands on which roll changing is taking place, and at the same time FIGURES 2 and 2acomprise a second set of drawings,
drawings.
FIGURE 1a is a fragmentary plan mill layout "of the first form which shows the portion of the mill at the right of the portion shown in FIGURE 1 of the first set of drawings.
FIGURE 2 is a fragmentary plan mill layout showing i the second form of the installation of the mill of the invention, illustrating the portion of the mill to the left in the second set of drawings.
FIGURE 2a is a fragmentary plan mill layout showing continuing to produce useful products from the mill.
, According to the invention, the customer in buying the mill, need make only a minimum initial expenditure and still he obtains a useful, basic mill. By two additional steps, the capabilities of the mill can be increased, both as "to product, types, and size of rolled stock.
In the basic mill of form 1, a roughing mill stand discharges on a mill table to anintermediate continuous mill, which in turn feeds a looping finishing mill discharging to asecond mill table which feeds a cooling bed.
I In the second step, advantage is taken ofthe lateral zig-zag configuration of the looping finishing mill to permit the installation of a lateral transfer device from the first run-in table, and a continuous finishing mill is fed by the lateral transfer device which utilizes the position of the'finishing stand bf thel looping finishing mill, the repeater being slid out of the way. Thus it is possible to roll on the lateral transfer and the continuous finishing mill while changing rolls on the intermediate continuous mill and on the early mill stands of the looping finishing mill.
In the third form of installation of equipment, a second roughing mill stand is introduced and the. number of stands of the intermediate continuous mill desirably increased. As a desirable feature also coiling equipment is installed in the third step. t q
Referring now particularly to the first form of installation as shown in FIGURES 1 and 1a, billets are loaded on loading skids 20 and discharged by feeding mechanism 21 into the paths of double pushers 22 of a double slide billet heating furnace 23 well known in the art. At the outlet end of the furnace the billets now heated to hot rolling temperature are discharged by billet ejector 24 on to run-in table 25 and past billet turnaround 26 all well known in the art. I
Run-in table'25 feeds the billet to roughing rolling mill stand 26' driven in well known manner'by motor 27 and speed reducer 28 underthe control of an operator in pulpit StlfThe roughing mill is suitably of the threehigh type and has a tilting or lift table 31 as well known in the art.
, The roughing mill stand 26' discharges the stock to m'ill'table 32 which is sometimes referred to herein as the first? mill table, past cropping shear 33 to mill the equipment of the continuous mill.
The stock passes to looping fininshing mill' il of a character in itself well known in the art, which suitably has a first roll stand 42, a second roll stand 43, a third roll stand 44 and a finishing roll stand 45 which are suitably. connected by a transfer guide 46, a first escapement repeater 47, a first inlet guide 48, a second transfer guide 50, a second escapement repeater 51, a second inlet guide 52, a third transfer. guide 53, a third escapement repeater 54, a third inlet guide 55, a fourth transfer guide 56, a final escapement repeater 57, a fourth inlet guide 58 and a mill table 60 to a flying shear 61. The mill table 6;;19 is sometimes called the second mill table.
For reasons which will later be more clearly set forth,
the repeater 57 is mounted to move laterally out of the way on tracks 62sothat it can remain in operative position as shown in FIGURE 1a or be shifted so' as to uncover the inlet side of finishing mill 45. For this. purpose fourth inlet guide 58 is also mounted on track 63 so that it will. move to the side along with repeater 57 when they are to be displaced. .Such track moving repeaters are in themselves well known in the art.
The mills will be drivenin any suitablemanner of which FIGURE 1a shows a suitable indication.
v A motor 80 drives speed reducer 81 which in turn drives the mill stands 42, 43 and 44. Likewise, a motor 82,
" preferably an adjustable speed type, combined with a speed reducer drives finishing mill stand 45.
The mill table 69 feeds, by suitable kickofi means as are Well known, to cooling bed 83., and from the cooling bed the stock is taken by mill table 84 through cold bar shear 85 to cradles 86 as .well known.
-It will be evident that the mill layout of FIGURES 1 and la is a completely operatiye mill which is capable of producing many products. V r
Using an 18 inch three high roughing stand and a 12 inch intermediate continuous mill having three stands and a looping finishing mill having four stands, typical products are as follows:
Products The second step in the expansion of the mill layout of the invention contemplates the provision of alternate means for shortcircuiting the intermediate continuous mill and the looping finishing mill through another mill which can operate while roll changing or other adjustments are accomplished on the intermediate continuous mill and the looping finishing mill.
Thus, as shown in FIGURES 2 and 2a there is no change in the heating furnace setup or in the roughing mill.
mented'to complete the continuous finishing mill byvertical edger 103 driven by adjustable speed motor 1M and speed reducer 105. The mill table continues between the continuous finishing. roll'stand 10!) and the vertical edger 1&3 and beyond the vertical edger 103.
The repeater 57 and the inlet guide 58 move together tothe side out of the'way and inlet guide 106 connected thereto moves with them into the path of the stock cozning from vertical edger 193 to finishing roll stand 45;
' In the preferred embodiment of FIGURE 2a, the continuous finishing mill stand 1% is of larger capacity than the finishing mill stand as used with the looping finishing mill so as to permit finishing material of larger crosssectional area -.and dimensions than possible with the final roll stand of the looping finishing mill. Thus, if the finishing stand 45 when used with the looping finishingmill is a 10 finishing stand, the horizontal mill stand 100 and the vertical edger 103 for the continuous finishing mill will conveniently be 14 mills. Then in order to get the most out of the finishing stand' of' the looping l, finishing mill the 10'. finishing stand 45 is conveniently replaced by a 14" finishing stand when the continuous finishing mill is used, and which may be fitted with appropriate rolls and guides prior, to the interchange.
.Thus there are two alternate procedures available in FIGURES 2 and 2a. The stock may for example pass through a 12". intermediate continuous mill and a 10".
looping finishing. mill, or it may pass through a 14" continuous finishing mill with a 14" finishing stand in place of the final stand of the looping finishing mill. In
the latter case the types of products which can be made will differ somewhat from those .which can bemade from the continuous mill plus the looping finish-ing mill. EX- amples of the product line'from the intermediate continuous finishing mill and the finishing standof the looping finishing mill using an 18", three-high roughing stand and .14" mill where required, a 14 vertical mill where required; a 12" intermediate continuous mill, and a looping finishing mill having four stands, are as follows:
Product Rebars: /2", 4', Ma", 1", 1%"
It will be noted that in making this change-over it is only necessary to change'from the 10'. to the 14 finishing stand in the looping finishing mill, by bringing in a new roll stand by the crane,
- The mill layout of the invention can be further eX- panded as shown in FIGURES 3, 3av and 3b.
In this instance the heating equipment remains the same but an additional'zroughing mill stand has been added, connected to ani additional speed reducer 121 A lateral transfer device 87, well known in the art,
driven by motor 27, and bar turners have been introduced at 122, 123 and 12.4. This permits a more rapid breakdown of the billet, or starting with larger billets, as desired.
In FIGURE 3a the intermediate continuous mill has been expanded to introduce an additional mill stand 125 driven from the same speed reducer 38, with corresponding shortening of mill table 32.
Optional coiling equipment 126 has been added including coile-rs 127 to permit taking off coilable rod directly beyond the flying shear 61.
By taking form as shown in FIGURES 2 and 2a, it will be possible to change much more quickly from one product to another, since the continuous finishing mill can be used while the intermediate continuous mill and the remainder of the looping finishing mill are undergoing r-oll changing or other modifications.
Finally, the additional roughing stand and the additional continuous mill stand of the form shown in FIG- URES 3, 3a and 3b will permit the use of larger billets or the production of smaller rolls from the same size billets.
If the coilers are added, then of course coiled rod can be produced.
I In some cases it will be more convenient to set up the looping finishing mill with the individual mill stands in line-rather than in staggered relationas shown in FIGURE 4, driving from motors and speed reducer-s 81 and 82' at the opposite sides of the looping finishing mill, motor 82 preferably being an adjustable speed type. In other cases, it may be convenient to eliminate the three or tour stand intermediate continuous mill.
In view of our invention and disclosure, variations and modifications to meet individual whim or particular need will doubtless become evident to others skilled in the art, to obtain all or part of the benefits of my invention without copying the structure shown, and we, therefore, claim all such insofar as they fall within the reasonable spirit and scope of my claims.
