Definitions
- This invention relates to rolling mills and is more particularly concerned with combination mills, which can be used either with difierent roll arrangements, such as four- .high or two-high- Thus, for example, in some circumstances it is desirable to have a four-high plate mill which is capable of conversion for use as a two-high slabbing
- a rolling rnill comprising a pair of fixed spaced apart housings adapted to alternatively receive a first roll arrangement consisting of a given number of rolls or a second roll arrangement consisting of a number of rolls greater than said given number, windows in said housings into which said two roll arrangements are alternatively received, the
- a mill having a pair of relatively fixed housings each having sides defining a window for reception of two or 'more roll bearingchock assemblies, the housing sides presenting bearing faces, for lateral support of bearing-chock assemblies, of greater width than the length of a roll neck whereby a pair of rolls each of a first length are receivable between the housings with the parts of the bearingchock assemblies surrounding the necks at a first inward I position in the housings to provide a two-high configuration or more rolls of a greater length than the spacing between the housings are receivable by the housings with the parts of the bearing-chock assemblies.
- the housings surrounding the necks at a second outward position in the housings to provide a roll arrangement of more than two-high configuration, the profile of the face of each housing side directed toward the other housing presenting a recess adjacent the zone of the roll bite whereby the roll arrangement of more than two-high configuration with rolls of greater length may work material of greater width than the spacing of the housings.
- FIGURES, 1 and 2 are part sectional elevation of a mill housing having respectively a two-high and a fourhigh roll arrangement, with the rolls at maximum separation;
- FIGURES 3 and. 4 are end elevations of the housings of FIGURES 1 and2 respectively with the rolls at minimum separation;
- FIGURE 5 is a horizontal section taken on line V--V of FIGURE 6 through the lower slabbing roll, when in position in the housings;
- FIGURE 6 is a section on the line of FIG- URE 5;
- FIGURE 7 is a section on the line VHVII of FIG- URE 9;
- FIGURE 8 is a section on the line VIII-VIH of FGURE 9.
- FIGURE 9 is an elevation of part of the two-high mill with the rolls separated.
- the combination mill has two housings 12, 13 which are secured together at a fixed separation appropriate to the widths of the plate mill rolls (160 inches, in the present instance).
- the two housings 1-2, 13 are similar to each other and each has a similar window 14 for the reception of the roll chocks.
- the housings 12, 13 and their windows 14 are appropriate to a four-high plate mill.
- FIGURES 2 and 4 show the arrangement when the combination mill is used as a four-high plate mill.
- a bearing-chock assembly 15 for the lower backup roll having an opening 16 for the back-up roll bearing,
- the upper work roll chock 22 is received, in known fashion, within a recess 22a in the upper back-up roll chock 20.
- a screw 24 engages against the top of chock 20 and a pair of hydraulic jacks 25 are arranged in a vertical passage within chock 17, one such jack 25 being shown in FIGURE 4, so as to engage between chock 17 and chock 22 and thereby to open the roll gap when the screw 24' on each housing is withdrawn.
- Hangers 19 engage beneath shoulders formed in chock 20 and are connected to a cylinder 19a mounted on top of the mill for urging the chock 20 for the two slabbing rolls 26, 27.
- the chocks for the rolls 26, 27 are shown at 30, 31 in FIGURE 1 and it positions in the windows 14 as did the chocks 17, 22 for will be seen that they occupy approximately the-same the work, rolls of the four-high mill.
- the spacev within the windows 14, previously occupied by' the back-up chocks 15, 20 are occupied by window-fillers 32, 33 which take the form of beams bridging the two housings 12, 13. Beam 32 lies in the windows 14 between the housings a part of the roller tables on each side.
- the hangers 19 engage beneath shoulders on the upper I roll chocks 31-and operate to keep beam 33 in contact with the screws. Because the slabbing mill rolls 26, 27" are narrowery thanthe plate mill rolls, the centerlines of the'chocks' I 30, 31 for each roll 26, 27 are, perforce, arranged inwardly of the center lines 37 (FIGURES) of the two housings 12, 13. For this purpose, housings 12, 13 have,
- extensions 40 which increase the lateral support for the rolls 26, 27, are discontinued at 41, in the region of the roll gap, in order to prevent obstruction of the full width'of the roll gap during'theuse of the mill for rolling plate.
- thechocks 30, 31 each have overhanging extensions 42, in order to enlarge the areas of support given by the housings to the chocks.
- the rolls 26,- 27 are .held in axial position by fingers 43, which are formed integrally with the extensions 42 and which are slidably held between the housing 12 and removable "keeper plates 44.
- a rolling mill comprising a pair of fixed spaced apart housings adapted to receive a first roll arrangement consistingv of a given number. of rolls of a first aggregate diameter, windows in said housings into which said first roll arrangement is received, roll adjusting means mounted in said housings, bearing-chock assemblies. mounted-on the ends of said rolls,.the length of.
- the rolls of said first roll arrangment being such that their bearing-chock assemblies are offset toward the center of said mill relative to said roll adjusting means, a filler beam received insaid windows when said first roll arrangement is in placefor carrying I I the bearing-chock assemblies of one of said -rolls-of said first arrangement and serving to transmit the rolling loads of said rollto said roll adjusting means, the firstrol l arrangement and beam being removable and replaceable by a second roll arrangement of greater aggregate diam- '-eter' than the first roll arrangement, the bearingrchock It has already been stated that the extensions of the housings 12, 13 are discontinued in the region of the roll gap, When the mill is being operated as a four-high,
- extension pieces may
- Each extension piece 45 is hook-like and is enabled to withstand the lateral loads applied to its by the chocks30, by virtue of the engagement of a shoulder 47 of the hooked part with a corresponding shoulder 47a on the housing.
- the housings 12, 13 additionally carry, on each side of the roll gap, a number of feed rolls 48 whichvform Although FIGURESS and 7 show only three such feed rollers 48, a
