Definitions

  • This invention relates to a continuous casting device for metals.
  • Continuous casting plants for metals generally comprise an upper ladle for pouring the molten metal, and an intermediate distributor from which the molten metal is cast into the underlying ingot moulds.
  • the distributor base is generally provided with a casting device consisting of a refractory element commonly known as a nozzle, comprising a sized vertical hole which ensures constant flow of the casting jet.
  • a drawback of this known device is the considerable time loss involved in its replacement, with consequent reduction in production yield.
  • the nozzle has to be replaced under the following circumstances: - when with the passage of time the sized hole enlarges so altering the molten metal flow rate to the extent of exceeding predetermined limits, so that casting has to be halted, - following clogging of the sized hole by the steel, - if the refractory element suffers damage for various reasons, - after a certain period of continuous casting.
  • casting devices comprising a slide gate consisting of a fixed plate and a mobile plate slidable horizontally to the fixed plate and housing a plurality of side-by-side refractory elements (nozzles).
  • nozzles side-by-side refractory elements
  • a nozzle is positioned coaxially to the casting hole and a pneumatic or hydraulic activator member horizontally moves the nozzles so as to position a new nozzle below the casting hole as a replacement for the damaged or otherwise inoperable one.
  • This known device has however certain drawbacks, and in particular: - the danger of steel seepage along the contacting walls of the refractory elements, - substantial operating cost as the refractory element comprising the damaged hole must necessarily be scrapped.
  • a continuous casting device for metals comprising a fixed plate mounted on the base of a distributor and a frame mobile horizontally to said fixed plate, characterised in that said mobile frame comprises a plurality of parallel sized holes.
  • each sized hole can be provided upperly with a sized ring.
  • the device of the invention is applied to the base of a tundish 1 and consists substantially of a slide gate comprising a fixed plate 2 and a metal frame 3 mobile to said fixed plate along parallel guides (not shown on the drawing).
  • the mobile frame internally houses a plate 4 of refractory material comprising a plurality of parallel vertical holes 5, each of which is provided upperly with a sized ring 6 having a greater diameter than the casting hole 7.
  • a jet covering tube which protects the molten metal jet as far as the underlying ingot mould.
  • a drive member 9 of pneumatic or hydraulic type is associated with the mobile plate to horizontally move said plate in order to position a new sized hole as a replacement for that previously damaged.
  • the improvement in the casting device according to the invention has numerous advantages, and in particular: - the facility for replacing the sized hole while the casting plant is in operation, - the ability to cast continuously for very long periods, - reduced operating costs because the calibrated hole ring can be replaced without having to scrap the entire plate.
