Definitions

  • the invention relates to a method for adjusting the adjustment speed of narrow sides of a plate mold in continuous steel casting, the distance between the narrow sides being increased during the continuous casting operation.
  • a method for controlling the cooling capacity of narrow side walls in plate molds during continuous casting is also known (CH-PS 558 687), in which the conicity of the mold is set to a desired value adapted to the intended casting speed and / or the casting temperature before the start of casting if the casting speed and / or the casting temperature changes during the casting operation, the taper is adjusted.
  • the molds are equipped with devices for measuring the cooling capacity in the narrow side walls and with adjustment devices for the narrow sides.
  • This object is achieved in that the amount of heat dissipated on the narrow sides during their adjustment is measured and the narrow sides are adjusted only so quickly that the amount of heat dissipated does not fall below a predetermined amount H and H according to the formula is calculated, where t is the dwell time (in min) of a strand element in the mold, 6000 is a constant (in kcal. min o.5. m - 2 ) and B is the width of the narrow side (in m).
  • the above-mentioned dwell time is calculated from the effective mold length L (in m) divided by the casting speed V (in m ⁇ min- 1 ).
  • the effective mold length L (in m) is the length from the steel bath level in the mold to the end of the mold. Since both the effective mold length L and the casting speed V are known, the amount of heat that can advantageously be dissipated is easy to calculate.
  • Running casting operation is understood to mean that during the adjustment of the narrow sides to broaden the format, there is a flow of steel into the plate mold from the upstream casting vessel.
  • the predetermined amount for the amount of heat to be dissipated is such that if the strand shell is in sufficient contact with the mold wall, it is strong enough at the end of the mold to prevent bulging or the occurrence of breakthroughs because measuring the amount of heat dissipated during the adjustment of the narrow sides Indicator for the contact of the narrow side with the strand formed and thus for the shell growth in the mold is given.
  • the adjustment of the adjustment speed is advantageously carried out fully automatically.
  • Devices for determining the amounts of heat actually removed are known per se, as are devices for adjusting the narrow sides.
  • a received actual value signal of the amount of heat dissipated on the narrow sides can be compared with the target value signal corresponding to the predetermined amount of the amount of heat to be dissipated and the resulting output signal can be used to control the adjustment speed.
  • the method can also only be used for setting the adjustment speed from one of the two opposite narrow sides, only the thermal output measurement of the moving side serving as a control variable.
