Definitions

  • This invention relates to continuous casting apparatus and more especially to apparatus for monitoring and sensing the positions of rolls which provide a path of travel for a continuously cast strand of metal as it solidifies.
  • Conventional continuous casting machines comprise a water-cooled open-ended mould from which a partially solidified metal strand is withdrawn and moved along a curvilinear path defined between a plurality of spaced driven and/or idle rolls which engage opposite surfaces of the strand.
  • the path of travel is generally vertical as the strand leaves the mould and generally horizontal as the solidified strand leaves the casting machine.
  • the strand is moved along the path defined between the rolls by a flexible dummy bar chain which is secured to the strand.
  • This chain is typically several metres long, is made of mild steel and weighs around 10 tonnes.
  • Dummy bar chains having integral sensors for monitoring the condition and spacings between pairs of rolls are known.
  • Known monitors include units comprising sensors and instrumentation electronics which form integral parts of one or more links of the chain.
  • chain links are replaced by customised links which contain the required sensors and associated instrumentation.
  • US-A-3937271 discloses apparatus for monitoring the positions of rolls of continuous casting machines which comprises a dummy bar chain having a block of integral position sensors.
  • EP-B-0014862 discloses similar monitoring apparatus which comprises an integrated measuring device including sensors and a computer means with a store. Neither of these documents discloses roll position monitoring apparatus which comprises a dummy bar chain to which the monitoring apparatus is detachably secured. In both documents, the monitoring apparatus is exposed to hazards caused by the harsh environments of continuous casting even when no measurements of roll positions are required. In the present invention, the monitoring apparatus is removed from the dummy bar chain on occasions when measurements are not required.
  • the environment within a continuous casting machine is particularly harsh. During casting relatively high temperatures are reached and water sprays are used to cool the strand. The resulting steam combines with the air, water mist sprays and running water to create an environment not conductive to longevity.
  • the present invention sets out to provide apparatus for monitoring and sensing the positions, conditions and alignment of rolls and related equipment of continuous casting machines which do not suffer from, or at least alleviate, many of the disadvantages discussed above.
  • apparatus for monitoring the positions of rolls of a continuous casting machine comprising a dummy bar chain to which is detachably secured monitoring apparatus which includes one or more sensors and associated electronic circuitry to monitor and sense the positions of rolls of a continuous casting machine, the apparatus being characterised in that the monitoring apparatus is attached to the dummy bar chain when the positions of the rolls are to be monitored and is detached therefrom when these positions are not to be monitored, the apparatus comprising a beam from the upper surface of which the sensors protrude and to the undersurface of which is secured a housing for the electronic circuitry, the beam being dimensioned to locate within indents formed in the upper surface of the links of the dummy bar chain with the housing positioned between opposed inner faces of these links.
  • the dummy bar chain preferably includes a pair of side-by-side links shaped to receive the monitoring apparatus with the apparatus generally aligned both longitudinally and laterally with the dummy bar chain.
  • Means may be provided for limited vertical movement of the monitoring apparatus relative to the dummy bar chain when the former is secured to the latter.
  • This means may comprise one or more pivotably mounted links.
  • the apparatus illustrated in Figure 1 of the drawings comprises monitoring apparatus 1 in accordance with the invention positioned above support links 2, 3 of a dummy bar chain 4.
  • the monitoring apparatus 1 is a double or articulated unit which can readily be assembled onto or removed from the support links 2, 3 of the dummy bar chain.
  • Monitoring apparatus 1 carries all necessary electronics and sensors to perform the required measurements.
  • the apparatus 1 includes a beam 5 from the upper surface of which protrude sensors 6 (which may be spring loaded) and from the under surface of which is secured a housing 7 containing the required electronics. Monitors 8 are suspended from the beam ends and are selectively detachable therefrom.
  • the chain links 2, 3 are shaped and dimensioned to receive the monitoring apparatus.
  • the electronics housing 7 locates between the opposed inner faces 9 of the chain links 2, 3 and the beam is positioned within indents 10 formed in the supper surface of each support link.
  • the monitors 8 extend into side channels 11 of the support links.
  • Figure 2 illustrates the apparatus when assembled on the dummy bar chain. It will be seen that, when assembled, the support links define a carriage for the monitoring apparatus.
  • the monitoring apparatus is able to float vertically to a limited extent relative to the support links of the dummy bar chain whereby either the upper or lower margin of the apparatus stands proud of the support links.
  • the ability to float is in a single axis and ensures inter alia smooth transition to and from the dummy bar carriage. It also ensures that the monitoring apparatus is held onto the outer face of the casting rolls under inspection regardless of the amount of tension within the dummy bar chain. Springs may be provided for this purpose.
  • the monitoring apparatus 1 may be connected to the chain links by one or more pivotably mounted links 14. These links operate to connect the monitoring apparatus to the support links which enable floating of the apparatus relative to the dummy bar chain.
  • a multiplicity of measuring heads may be carried by the monitoring apparatus.
  • These heads may include roll rotation units 15, bend sensors 16 and inclinometers 17.
  • Measurements taken by the monitoring apparatus include the gaps between roll pairs of a continuous casting machine, tangential measurements of neighbouring rolls to provide measurements of roll alignment, roll rotation measurements, analyses of the water spray pattern within a casting machine and measurements of eccentricity of the centre of a roll when the roll is supported at and rotated about its bearings.
  • Spring anvils 18 may also be provided to ensure contact of the measuring devices with the respective rolls.
  • the loading/unloading procedure of the monitoring apparatus to/from the dummy bar chain has been designed to be a quick and simple procedure.
