Definitions

  • the invention relates to a method for determining the friction between Strand shell and mold during continuous casting using an oscillating mold.
  • the frictional force between the mold wall and the strand shell is determined by a normal force caused, which acts on the strand shell.
  • the normal force arises mainly as a result of the ferrostatic pressure that the steel melt has on the inside of the strand Strand shell exercises.
  • An additional portion of the frictional force is from the conical Employment of the mold narrow sides caused.
  • the measurement of the frictional relationships between the strand shell and Chill mold is also essential because the mold friction acts as a pulsating disturbance variable on the strand.
  • the object of the invention to provide a method of the type mentioned in the preamble of claim 1, which while avoiding the aforementioned disadvantages and difficulties with comparatively little technical effort and without any noteworthy Modifications to the mold or oscillation device provide clean measurement signals, no external sensors and / or vibration models required and continuously online to monitor a trouble-free operating status required operating data, in particular for determining the friction between Strand shell and mold supplies.
  • the invention provided that using regulated double acting Hydraulic cylinders the pressures of both chambers of all oscillation cylinders, as well as the stroke positions of the pistons that can be assigned to these pressures with a predefinable one Measuring frequency recorded and from this data at any time friction force acting between the strand shell and the mold walls is calculated becomes.
  • the method according to the invention for determining the friction between the strand shell and mold during continuous casting can be used with all continuous casting machines use that are equipped with a hydraulic mold oscillation.
  • An embodiment of the method according to the invention provides that the determined Frictional forces assigned to the current casting speed and with it be continuously compared. This is a change in the casting speed adequately compensated as a disruptive factor.
  • a further embodiment of the method according to the invention provides that the Acceleration forces depending on the respective stroke position in the cold run is determined without friction forces, with corresponding acceleration forces including the frictional forces in intact casting operation compared and the TARGET values of the permissible friction forces are derived from it.
  • Another embodiment of the method according to the invention provides that as further influencing parameter parameters for steel quality, casting temperature, casting speed be taken into account when calculating the friction force.
