Definitions

  • the passages can extend (Search v. .1 across the mold or a number of parallel passageways can be 273, 348 distributed across the mold.
  • This invention relates to a cooling device for continuous casting of strip metal. More particularly, this invention relates these cooling devices have used relatively large chambers for Y the passage of the coolant water while the water has had a relatively low'rate of speed in flowing through the chambers. This has led to the "formation of boiler scale in the cooling devices and has thus'caused accumulations. of heat which can result in troubles in the'contin'uous casting operation.
  • the invention provides a cooling device for the mold of a continuous casting apparatus which fcooperate's with'the mold to cool the mold byforrning a narrow gap so thatwater flowing through the gap flows in a thin high speed film.
  • the surfaces of the cooling device defining the gap extend substantially parallel to the plane of the strip being cast within the mold and across the width of thecooling device.
  • the gap is of a thickness in the order of 0.5 to 1 mm. and the speed of the flow of water is from '2 to 20 meters'per second.
  • FIG. 1 illustrates alongitudinal cross-sectional view of an description and appended claims taken in conjunction with apparatus of theinvention
  • defining the gap l3 constitute guiding surfaces for a stream of cooling water which enters from an inlet 11 in the cover9 and exits from an outlet 12 in the opposite end of the cover 9.
  • the water forms a thin fil and flows in a direction opposite to the movement of the strip 4 at a speed of from 2 to 20 meters'per second.
  • the cover 9 is shaped to define a distribution chamber 14 withpart 2 at the upstream end of the gap 13 and a collecting chamber 15 at the downstream end of the gap 13.
  • the transition from the gap 13 to the collection chamber 15 is trumpet shaped in order to achieve a good cooling action as close as possible to the mold inlet.
  • the flow of water through the respective gaps 13 can be varied by varying the supply of water to the gaps so as to vary the cooling effect across the'width of the strip 4. Also, in order to avoid blockage in the gaps l3, filtered water can be fed through the cooling device.
  • each surface bounding the narrow side of the strip are formed by separate mold parts.
  • FIG. 2 illustrates a fragmentary transverse cross-sectional view of the apparatus of FIG. 1.
  • the mold 1 is constructed of two parts and is connected in a known manner at the left end as viewed in FlG.l to a furnace (not shown) containing molten metal ora molten metal alloy.
  • the mold'l is preferably made of graphite and is surrounded by a cooling device 2, 3so that as molten metal flows into the mold 1 from the furnace the cooling device 2, 3 influences the metal to solidify into astrip 4.
  • the strip 4 is moved out of the mold 1 either continuously or intermittently in the direction indicated by the arrow 5 by 'a suitable drawing device (not shown).
  • the parts of the cooling device 2, 3 extend above and below the broad sides of the strip 4 and abut against the. mold 1 in heat transfer relation therewith.
  • the parts 2, 3 are held together by suitable means, such as, screws, as indicated by the design lines 6 in FIG. 2 on opposite sides of the mold 1 in heat transfer relation therewith.
  • Part 2 of the cooling device which is constructed in a similar manner to part 3 has, a pair of recesses 7, the bottom surfaces 8 of which are substantially parallel to the plane in which the strip 4 moves.
  • a cover 9 is disposed in each recess 7 with the underside l0 spaced from sense.
  • the invention thus provides a cooling device wherein a nar-v row gap is formed to conduct a thin film of coolant at relatively high speed. This substantially avoids the formation of boiler scale in the cooling device. Further, the invention allows an increase in the coolingeffect by improving the heat extraction.
  • a combination with a mold of porous material for a cooling device comprising a pair of parts removably disposed on two opposite sides of said mold in abuttment therewith, each said part having at least one narrow gap therein parallel to and spaced from said mold and means for directing the coolant through said gap, said gap being of a size to guide the flow of coolant within each part in a thin film at high speed; and
  • each part includes arecess therein having a bottom surface parallel to said mold, and a cover disposed in'said recess having an un-.
