Definitions

  • ABSTRACT Foreign Application Priority Data
  • a continuous casting machine having a mold and means for withdrawing and guiding a casting emerging Sept 1970 Germany 20 46 6459 and lowered from the mold, a pair of endless belts or chains carrying plates and disposed on opposite sides (g1.
  • Endless belts or chains have been used for supporting a casting upon withdrawal'from the mold.
  • plates or plate-like chain elements have smooth surface that engage the casting.
  • the casting requiresalso cooling, and it was found otherwise that direct cooling is much more effective than indirect cooling, at least right below the mold. Covering the casting by means of such plates reduces, therefor, cooling in the zones to what is now secondary cooling. This disadvantage is particularly noticeable for a high production rate and high withdrawal speed of the casting as lowered from the mold.
  • These belts or chains are to have plates that are urged towards the casting from opposite sides and run therewith at casting withdrawal speed. It is a particular feature of the present invention that the plates have relief profile to engage the casting with less than the entire surface of a plate as facing the casting.
  • the protrusions, elevations, projections etc. that engage the casting and establish the relief areto cover not more than 50 percent, of the plate surface; preferably they cover only to 30 percent.
  • the type of protrusions that form the relief may differ. It was found of advantage to use dot-like or circular-like protrusions. Annular protrusions should have diameter of about 10 to 40 mm. Alternatively, the protrusion may set up a line pattern, the lines having width of about 10 to 40 mm. Still alternatively, the protrusions may constitute a grid or lattice structure disposed on or being part of a perforated base. The lattice type protrusions may be rhombic, rectangular or, preferably, they may be constituted by a network of annular bosses. The plates are arranged on an endless belt or chain or chains driven by pulleys as is known per se.
  • Water for cooling is sprayed in between the plates, laterally therefrom and through perforations in the plates, whereby the cooling water is distributed in the channels formed around or along the protrusions between the corresponding indentations of the plate and the adjacent casting skin.
  • FIG. 1 is a side elevation with section through the casting and mold and showing additionally the novel withdrawal arrangement in accordance with the preferred embodiment of the invention.
  • FIGS. 2, 3, 5 and 6 show side views of plates with different surface relief profile
  • FIGS. 2a and 4 being respectivelysections through lines 2a2a and 4-4 inFIGS. 2 and 3.
  • FIG. 1 a mold 1 for continuous casting.
  • Liquid metal is poured'into the mold and a casting 2 is lowered and withdrawn from below.
  • the casting has a solidified skin 2' whichis quite thin immediately below the mold, mostof' the interior of the casting being occupied by a downward extension of the liquidous pool 2" in the mold.
  • the skin 2' grows with distance from the mold.
  • the belt drives will be synchronized to the withdrawing drive so that the belts move at the lowering speed of the casting.
  • the belts are tensioned and guided by idler pulleys and by rolls 7 mounted on a support frame 8. Rolls 7 provide a particular force for urging plates 4 against the casting. Below the belts, it is presumed that the skin 2' has attained sufficientthickness so that regular rolls such as 6 suffice to support the casting.
  • water is sprayed from the interior of the belt system, the coolant being fed laterally thereto.
  • the water is sprayed onto the belts from the respective rear to pass through perforations therein as well as through perforations in the plates 4 and in between adjacent plates
  • the belts are arranged in pairs, one pair being shown to engage opposite sides of a slab ingot. The two sides transverse thereto may be engaged and supported by a similar pair of belts with plates.
  • FIGS. 2 and 2a various configurations for the plates surfaces will be described.
  • a plate is shown with a plate base it) proper having protrusions 11 in form of ridges, arranged in a herring-bone pattern, the inclination being in direction of casting (arrow A).
  • the space between the protrusions form cooling channels so that water sprayed transversely to the plane of the drawing runs readily into these channels from above and down along the casting. It is also for this reason that the ridges should not be wider than about 40 mm, to minimize the local areas of indirect cooling.
  • the plate is established by a frame 15 and bars 12 to provide a lattice or grid structure and configuration, leaving perforations 14, through which water is sprayed from behind.
  • Circular bosses 13 are provided on the bars 12, for engagement with the casting. The bosses are quite large in number, so that there is a dense network of support points for the casting over the entire plate surface, but minimizing areas of contiguous contact.
  • the plate of FIG. 5 is somewhat simplified; the plate 19 is flat and is provided with perforations 24, the remaining sections 18 between the perforations establish the profile.
  • FIG. 6 shows a plate that has also a frame 21 with cross bars or struts 12 leaving perforations 23.
  • the frame as well as the cross bars carry protrusions 25.
  • These protrusions are circular, preferably annular, each having a central opening 26. Spray water may, thus, pass through the perforations 23 as well as through openings 26.
