Boxall M MM ATTDE N EYS 3,097,971 METHOD OF AND APPARATUS FOR SUPPORTING OR GUIDING STRIP MATERIAL Samuel Skipton Carlisle and Genefer Margaret Boxall, London, England, assignors to The British Iron and Steel Research Association, London, England Filed Nov. 9, 1960, Ser. No. 68,226 15 Claims. (Cl. 134-15) This invention relates to the support or guidance of strip material, such as, for example, steel strip passing through an electrolytic tinning line, continuous annealing line or the like.
According to one aspect of the present invention there is provided a method of supporting or guiding strip, material which comprises introducing a supply of pressurized fluid between a surface, across which strip material is caused to travel, and the adjacent surface of the strip material, whereby the strip material is maintained out of contact with said surface.
According to another aspect of the present invention there is provided apparatus for supporting or guiding strip material Comprising a support member, and means for introducing a supply of pressurized fluid through said member to a support surface thereof.
The above method and apparatus of the present invention provide, therefore, a low friction bearing. Furthermore, it is possible to avoid or reduce differential tensions in parts of or the whole of, strip material without adjusting and maintaining the adjustment of the surface speeds of a number of rollers, as is usually the case. Also changes of strip speed may be made without difficult problems of roller speed adjustment.
Application of the invention is particularly suitable for supporting and guiding materials, such as ferrous strip for tinplate manufacture, which require a high standard of surface cleanliness and surface finish.
In order that the present invention may be more clearly understood, the same will now be more fully described by way of example with reference to the accompanying drawings, in which:
FIGURE 1 illustrates diagrammatically one embodiment of the invention,
FIGURE 2 shows a modified support member for the embodiment of FIGURE 1,
FIGURES 3 and 4 show an enlarged, fragmentary side and plan view, respectively, of one form of support member.
FIGURE 5 illustrates alternative forms of support members, and
FIGURE 6 illustrates a preferred feature of support members according to the invention.
In the embodiment of FIGURE 1, means are provided for guiding a strip of material 1 'along a serpentine path. Such an arrangement meets a common requirement where, for example, a length of strip is to be contained for a period of time in a gaseous or liquid environment within a treatment vessel or chamber of reasonable dimensions. Fixed support members 2 are located at each bend position, each member having a convexly shaped support surface perforated with a number of holes through which a fluid, such as air, for example, is forced towards the strip. Pressurized fluid is trapped between the support surface and the strip for a suflicient time to form a cushion on which the strip floats while being pulled through the apparatus by draw rolls 3.
Where the strip is being pushed towards the support members, as opposed to, or in addition to being drawn away from them, the members may take the form shown in FIGURE 2. Here, the member 4 has a concavely curved support surface towards which the strip is driven by rolls 5. Preferably, a co-operating convexly curved United States Patent 0 3,097,971 Patented July 16, 1963 member 6 is also employed with member 4 as shown, to form a channel for passage of the strip and to provide increased control over the strip as it passes that point. Furthermore, the spacing between members 4 and 6 may be increased at the entrance to the channel, as illustrated, to facilitate entry of the strip.
Various arrangements may be used to supply fluid to the support surfaces. For example, in FIGURES 3 and 4 which show enlarged views of a convexly curved support member, a series of orifices 7 are provided near the longitudinal edges of the supporting part" 8. These orifieslead from a cavity 9 to which fluid is supplied at the appropriate pressure.
Further orifices 10 are provided towards the centre of the support surfaces and may be fed with fluid at lower pressure than orifices 7. Alternatively, where a common cavity is employed for supplying all of the orifices, differential orifice outlet pressures may be obtained by suitable design of the orifices themselves.
In another arrangement for supply of fluid to the support surfaces use is made of slit orifices as illustrated in FIGURE 5, for example.
The embodiment of FIGURE 5(a) only makes use of peripheral slit orifices 11, while those of FIGURES 5(b) and 57(c) show how additional slit orificeslz may be disposed to obtain increased support in the case of heavy strip material or wide material more properly regarded as of sheet form.
If desired the slit orifices may contain discontinuities instead of being continuous as shown in FIGURE .5. However, such discontinuities should generally be small in comparison with the required clearance between the support surface and supported material.
Clearly other variations of orifice form and disposition are possible and one such example is a combination of peripheral slit orifices and conventional circular orifices disposed in the central region of the support surface such as the orifice 10 of FIGURE 4.
Preferably the peripheral orifices, be they of circular, slit, or other form are angled to direct fluid towards the centre of the support surface as illustrated by FIGURE 6. This enhances the cushion effect of the fluid and delays the escape of fluid from between the support surface and supported material. Also, this angle may be varied as between the input and output sides with respect to the strip to take account of any slipstream effect set up by the strip motion. A
The positioning of the orifices, their design and size, and the pressure of fluid applied to them are all factors which may be varied as appropriate to achieve the optimum use of the fluid employed according to the weight of strip to be supported, its dimensions and flatness.
The pressure of fluid may be adjusted in any event to vary the clearance between the strip and support surface as demanded by surface conditions or thickness of material. Thus, the fluid pressure may be increased temporarily to take account of increased strip thickness in the form of a lap joint, for example.
The invention may be applied in processes involving thermal or chemical treatment of strip by employing bearing fluid of suitable composition and temperature. In particular, the invention may be used for guiding and supporting tinpl ate during drying after wet treatment or during flash heat brightening of electrolytic tin coating.
The strip may also be used for guiding and supporting strip during continuous annealing, or any thermal or chemical or thermo-chemical process in a vapor or gas environment, or during any cleaning or surface treatment process in a liquid environment.
The invention also finds application in the temporary storage means for moving strip'commonly referred to as reservoirs.
Although the above description refers almost exclusively to support or guidance of strip material, the expression strip material, also used in the claims hereinafter, is intended to include wide elongate material of various kinds which may sometimes be referred to as sheet material whether it be in continuous form or in a discrete sheet form.
In the case of a discrete sheet, the invention may be applied to a support table and the supporting jets switched on automatically, by photoelectric means, for example, as the sheet passes over successive sections of the table.
