Definitions

  • the present invention relates to a method for the lubrication of a mold for the continuous casting of metal, in particular steel.
  • the cast metal has a solidified skin of an already significant thickness, which implies cooling of this skin with respect to the molten metal; it follows that the wall of the mold, energetically cooled, is at a temperature much lower than the melting point of the powder. The internal face of this wall is thus covered with a layer of solidified powder, which is formed to the detriment of the film of lubricating agent and which consequently reduces its effectiveness.
  • the subject of the present invention is a method which makes it possible to remedy this drawback by ensuring additional lubrication, in particular in the region near the base of the mold for continuous casting.
  • the process which is the subject of the present invention is thus characterized in that at least one orifice is passed through the wall of the ingot mold, in that a lubricant is introduced through said orifice and in that one causes the melting of said lubricant, so that it is spread between the wall of said mold and the metal poured into said mold.
  • the said lubricating agent is introduced in the form of a bar made up of a powder having a melting point below the temperature of the material located opposite the said orifice.
  • this material can either be the already solidified skin of the cast metal, or powder frozen on the internal face of the wall of the mold.
  • the bar of lubricating agent melts and lubricates the mold.
  • the melting of the lubricating bar leads to the melting of the frozen powder, the mixing of the two molten powders and the resumption of lubrication of the mold.
  • the said lubricant is subjected to preheating, and possibly to the start of melting, while it is in the said orifice of) passage through the wall of the mold.
  • the present invention also relates to a device making it possible to implement the method which has just been described.
  • the device of the invention is characterized in that it comprises means for ensuring the introduction and the progression of a lubricating agent through the wall of the ingot mold, and means for thermal insulation of the said lubricating agent in relation to the cooling system of the mold.
  • the term "wall of the mold” should be understood to mean “all the faces of this mold.
  • the device is also equipped with means for heating and / or for melting said lubricating agent.
  • said heating and / or melting means advantageously consist of a Joule effect heating circuit.
  • the attached figure represents a device according to the invention, installed in the lower zone of a continuous casting mold.
  • the ingot mold 1 is provided with a water cooling circuit shown diagrammatically by the arrows 2 and 3, water inlet and outlet respectively.
  • two ovens 4 provided with through holes 5 5 through which bars of lubricant 6 can enter the mold.
  • These ovens are provided with a Joule effect heating system by means of an electric current I. They are separated from the cooling water by the watertight partitions 7; they are also lined with thermal insulation material 8, in order to avoid any untimely heating of the cooling water of the ingot mold 1.
  • a liquid metal for example molten steel is poured into this ingot mold , a solidified skin 10 is formed on the lateral surface of the ingot 9, the thickness of which increases in the direction of progression of the ingot.
  • the powder 11 deposited on the upper surface of the molten metal melts and, as a result of the oscillation of the ingot mold, flows between the walls of the ingot mold 1 and the skin 10 of the ingot.
  • the invention relates to a mold for continuous casting of metal, in particular steel, preferably equipped in each face with at least one lubrication device as just described.
