Definitions

  • This invention relates to a spray unit for supplying cooling and/or lubricating liquid to the rolls of a rolling mill or to the material being rolled therein.
  • a so-called spray bar which extends widthwise of a mill stand, the spray bar being fed with liquid under pressure and being provided with suitable nozzles disposed so as to emit the lubricant in the desired direction.
  • Valves are provided within the rolling mill system in order to control the emission of lubricant through the nozzles and these vales work on the "on/off" principle, i.e. they are either fully open or fully closed.
  • a spray bar is provided with a valve arrangement which is simple, comparatively inexpensive and easy to maintain.
  • the present invention provides in one aspect a spray unit for a rolling mill comprising a spray bar which is adapted to be mounted adjacent the mill rolls and which has a manifold for liquid to be sprayed; a series of spray nozzles or sets of spray nozzles spaced along the bar and communicable with the manifold; and, for each nozzle or set, a diaphragm-type valve arranged to control flow of liquid from the manifold to the respective nozzle or set of nozzles.
  • the diaphragm valves may be actuated by pneumatic means.
  • each spray nozzle or each set of such nozzles has a supply pipe with an open end accessible to the manifold; the valve for that nozzle or set then comprises a flexible diaphragm which is controlled either to engage and obturate the open end or to allow communication between the pipe and the manifold.
  • the diaphragm may form part of a chamber to which fluid under pressure may be supplied to control its obturating action.
  • a rolling mill 2 has two roll assemblies, exemplified by work- roll 4 and back-up roll-8, and work roll 6 and back-up roll 10.
  • a workpiece W is shown as being rolled between the two assemblies.
  • the mill is provided with spray bars 12, 14 arranged adjacent the mill and parallel to the roll axes.
  • the spray bar 12 has spaced along its length sets of nozzles, each set comprising a jet nozzle 16.for directing fluid to the top back-up roll, a nozzle 18 for directing fluid to the top work roll and a nozzle 20 for directing fluid to the upper side of the workpiece.
  • Spray bar 14 is similar, having nozzles 22, 24 and 26 for directing fluid to the bottom back-up roll, the bottom work roll and the underside of the workpiece respectively.
  • spray bar 14 is formed as a manifold 28 having a chamber 30 and an adaptor 32 is threaded into the manifold.
  • a nozzle bar 34 attached to the manifold 28 has, for each set of nozzles, three passages 21, 23 and 25 which open to the exterior of the nozzle bar and which are threaded to receive the jet nozzles 22, 24 and 26.
  • the passages 21, 23, 25 open to a normally plugged blind hole 36 within the nozzle bar 34, communicating with a tapped hole 42 aligned with an opening 40 through the adjacent wall of the manifold 28.
  • a tubular member 38 passes through the hole 40 in the manifold and is threaded into tapped hole 42 there being one tubular member 38 in respect of each set of nozzles. As shown, member 38 extends across the chamber 30, i.e. transversely of the roll axes and partly into an opening in the opposite wall of the manifold 28.
  • Each set of jet nozzles 22, 24, 26 has its own control valve for controlling flow of lubricant from manifold chamber 30 to the nozzles.
  • Each valve is similar and comprises an enclosure plate 44 secured to the exterior of manifold 28 by means of nuts 46 threaded on to studs 48, and defining compartment 50 aligned with the open end of tubular member 38.
  • a pipe 52 is connected to a tube 54 which connects with the compartment 50 at 56.
  • a diaphragm 58 is securely clamped between the plate 44 and the manifold 28, so that it closes off compartment 50 and the opening in the adjacent wall of the manifold; the diaphragm is spaced slightly from the end of member 38, there being normally a gap between the adjacent face 60 of the tubular member 38 and the face of the diaphragm:
  • a supply of compressed air is provided and this is fed as desired from each pipe 52 and tube 54 to the respective compartment 50 to deflect the diaphragm 58 into firm contact with the face 60 of the tubular member 38, thereby to close off the nozzle set and prevent the passage of lubricant from the manifold chamber 30 to the nozzles.
  • Coolant/lubricant fluid under pressure is supplied via the adaptor 32 in the chamber 30 of the manifold 28.
  • lubricant passes through the bore of that member into hole 36, and thence to the jet nozzles 22, 24, 26 - to spray on to the rolls 6, 10 and the workpiece W.
  • valves constituted by the diaphragms 58 in Figure 2 may alternatively be operated under electrical control, by means-of a solenoid for each valve and a control circuit for selectively energising the solenoids to bring the diaphragms 58 into obturating positions in relation to the ends of the member 38.
  • valves The electrical operation of the valves is illustrated in Figure 3 and 4, where the spray bar 14 is shown in outline, with the nozzles, represented by the uppermost 26, projecting therefrom.
  • the enclosure 50 of each valve is dispensed with and plate 44 is replaced by a housing 70 containing the solenoid for the respective diaphragm 58.
  • a separate line 72 for each valve leads from a control box 74 to the respective solenoid, which is also connected to a common return line 76. Selective energisation of lines 72 results in selected valve diaphragms 58 being brought to the closed positions.
  • Figure 4 shows a generally similar arrangement, but using encoded signals on a common control line 72.
  • the control box 74 incorporates an encoder which emits on line 72 a coded signal according to the particular valve that is required to be operated.
  • Latched solenoids are employed and each has a decoder which decodes any signal designated for it and passes it to the solenoid to change over the condition of the latter.
  • Control of individual valves may be effected manually or patterns of valves may be selected automatically under computer control.
