Abstract
A triplet mill has a housing structure (1) which defines a chamber, a pair of horizontal rolls (13) and two pairs of vertical rolls (17, 19) contained within the chamber, each roll having a bearing chock assembly on each of its necks and one pair of vertical rolls disposed on each side of the pair of horizontal rolls and, in the direction parallel to the direction of movement of material through the mill, the chock assemblies of the vertical rolls are arranged to abut against the housing structure and the chock assemblies of the horizontal rolls are arranged to abut against the corresponding chocks of the vertical rolls. <IMAGE>

SPECIFICATION Rolling mill
5 This invention relates to a rolling mill of the type comprising a first set of vertical rolls, a set of horizontal rolls and a second set of vertical rolls which are disposed very closely together. A mill of that type is described and illustrated in British Patent 10 Specification Nos. 1390537 and 142313 and will be referred to hereinafter as a "triplet mill".
According to the present invention, a triplet mill comprises a housing structure defining a chamber, a pair of horizontal rolls and two pairs of vertical rolls 15 disposed on one side of the pair of horizontal rolls and the other pair of vertical rolls disposed on the opposite side of the pair of horizontal rolls and in the direction parallel to the direction of movement of material through the mill, the bearing chock assem-20 bly of each pair of vertical rolls abuts against the housing structure on one side and against the bearing chocks of the horizontal rolls on the other side.
With this construction, the rolls are held in close 25 relation to each other. Vertical movement of the horizontal rolls is permitted by the bearing chocks of the horizontal rolls sliding on the bearing chock assembly of each pair of vertical rolls.
In one embodiment of the invention, each roll is 30 rotatably mounted in a pair of bearing chocks and the bearing chocks of the horizontal rolls abut against the bearing chocks of the vertical rolls.
In an alternative embodiment, each roll is mounted in a pair of bearing chocks and the bearing 35 chocks of each vertical roll of each pair of vertical rolls are arranged in a cassette having a pair of opposed side plates consituting part of the bearing chock assembly. It is the side plates which abut against the housing structure and the bearing chocks 40 of the horizontal rolls.
The construction according to this invention enables roll changing to be carried out with relative ease.
In order that the invention may be more readily 45 understood it will now be described, by way of example only, with reference to the accompanying drawings, in which:-
Figure 1 is a plan of a rolling mill in accordance with the invention,
50 Figure2 is a sectional side elevation on the line C-C of Figure 1,
Figure 3 is a sectional plan on the line B-B of Figure 2, and
Figure 4 is a plan view of a roll arrangement 55 according to an alternative embodiment of the invention.
Atriplet mill comprises a housing structure 1 containing a pair of horizontal rolls and two pairs of vertical rolls. The horizontal rolls are driven by a 60 motor 3 through a pinion box 5 and a pair of drive spindles 6. Each pair of vertical rolls are driven from their lower end by means of a drive motor 7, a drive shaft9 and a pinion box 10.
As can be seen in more detail in Figure 3, the 65 structure 1 defines a chamber 11 in which the rolls are located. Each of the horizontal rolls 13 is provided with bearing chocks 15 at its roll neck and each of the vertical rolls 17,19 is provided with bearing chocks 21 at its roll neck. In the case of each pair of vertical rolls, the bearing chocks constitute a bearing chock assembly for the rolls. In the direction parallel to the direction of movement 23 of material through the mill, the bearing chocks 21 abut against the housing structure and against the bearing chocks 15. The rolls of each pair of vertical rolls are movably horizontal towards and away from each other, and the horizontal rolls can be raised or lowered to adjust the gap between them. Wear plates provided on the bearing chocks permit the relative movement between the chocks to readily take place.
The housing structure defines an opening 25 through which the roll assemblies are displaced for roll changing purposes. The roll changing process is asfollows:-
(a) the horizontal rolls 13 and their bearing chocks 15 are displaced on a sledge 27 (see Figure 2)
through the opening 25 on to a trolley 28 on guides 29 positioned on the roll change side of the mill,
(b) the vertical rolls 17 and their bearing chocks 21 are displaced to the centre of the housing structure and then through the opening 25 on to the trolley 28,
(c) the set of vertical rolls 19 and their bearing chocks 21 are moved to the centre of the housing assembly and then displaced through the opening 25 on to the trolley 28,
(d) replacement sets of vertical rolls are displaced in turn from the trolley 28 into the respective places in the housing structure and, finally,
(e) the replacement horizontal rolls are displaced from the trolley into the mill structure.
Between each movement of the rolls, the trolley supported on the guides 29 is displaced by one step along the guides, thus enabling worn rolls to be positioned on the trolley and replacement rolls to be displaced from the trolley into the mill.
In an alternative roll arrangement, each pair of vertical rolls and their bearing chocks are located within a casette which forms part of the bearing chock assembly for the pair of rolls.
Referring to Figure 4, the vertical rolls 19 are supported in baring chocks 21 which are positioned between a pair of parallel plates 30 joined together by straps 31 to form a cassette.
The bearing chocks and the cassette consitute a bearing chock assembly for the two vertical rolls 19.
Similarly, the rolls 17 are supported in bearing chocks 21 positioned in a cassette formed by parallel plates 30 joined together by straps 31. The bearing chocks and the cassette constitute a bearing chock assembly for the two vertical rolls 17. In this arrangement, the bearing chock assembly of each pair of vertical rolls abuts against the housing on one side and against the bearing chocks of the horizontal rolls on the other side.
An opening 32 in each of the parallel plates 32 enables the workpiece to be passed between the rolls.

Claims (5)
1. A triplet mill comprising a housing structure defining a chamber, a pair of horizontal rolls and two 5 pairs of vertical rolls contained within the chamber with one pair of vertical rolls disposed on one side of the pair of horizontal rolls and the other pair of vertical rolls disposed on the opposite side of the pair of horizontal rolls and in the direction parallel to 1 o the direction of movement of material through the mill, the bearing chock assembly of each pair of vertical rolls abuts against the housing structure on one side and against the bearing chocks of the horizontal rolls on the other side.

2. A triplet mill as claimed in claim 1, in which each vertical roll is rotatable in a pair of bearing chocks and the chocks of each pair of vertical rolls are contained within a cassette which forms parts of the bearing chock assembly of that pair of vertical 20 rolls.
3. A triplet mill as claimed in claim 1, in which the vertical rolls are driven at their lower ends.
4. A triplet mill as claimed in claim 1 or 2, in which the housing structure defines an opening
25 leading from the chamberto the exterior of the mill, said opening being sufficient size to permit the rolls to pass one-at-a-time therethrough.
5. A triplet mill substantially as hereinbefore described with reference to the accompanying draw-ings.
