Definitions

  • the invention relates to a continuous caster with a heatable multi-chamber furnace with an oven-dependent mold for casting a molten metal.
  • DE 43 25 432 discloses a horizontal continuous casting installation with a holding vessel designed as a pressure chamber, which is fed with the molten metal to be cast through an inlet channel and from which the molten metal is removed via a pouring channel and fed to a mold.
  • the warming vessel is closed pressure-tight with a lid to which a pressure generating device is connected.
  • the level of the molten metal in the pouring channel is kept constant by varying the pressure conditions in the holding vessel according to its degree of filling.
  • bath level detection devices are provided in the pouring channel and in the holding vessel, which refer directly to the medial boundary layer between the volume of the pouring channel or the holding vessel filled and unfilled by the molten metal. From experience in the operation of such devices, however, it is known that mechanical, thermal or electrical bath level detection devices in such an arrangement are very unreliable on the one hand because of the high temperatures and on the other hand, in particular when casting heavy metal alloys, because of the slag accumulation that occurs.
  • the invention is therefore based on the object of specifying a continuous casting installation of the type mentioned at the outset in which the reliability of the level measurement is improved and in which the parallelism of the longitudinal directions of the mold is maintained regardless of the thermal conditions of the furnace
  • FIG. 1 a schematic, partially sectioned illustration of a horizontal continuous casting installation is shown in FIG. 1
  • An essential part of this horizontal continuous caster is a pressure-controlled multi-chamber furnace 1, which has a pressure chamber 3, which is fed with the molten metal to be cast through an inlet channel 2, and a mold chamber 4, which is in flow connection with the pressure chamber 3.
  • the pressure chamber 3 is assigned a pressure generating device 11, with which the gas pressure of the melt-free volume above the bath level in the pressure chamber 3 is regulated as a function of the degree of filling of the multi-chamber furnace 1 in order to maintain a constant metallostatic pressure in the mold chamber 4.
  • the multi-chamber furnace 1 is dynamically supported on a weighing device 6, with which the gross weight of the multi-chamber furnace 1 is recorded.
  • this Gross weight which is composed of the empty weight of the ready-to-operate multi-chamber furnace 1 and the weight of the molten metal located in the multi-chamber furnace 1, a measure of the degree of filling of the multi-chamber furnace 1 and as such a control variable for the pressure generating device 11.
  • the measurement quantity gain for the degree of filling of the multi-chamber furnace 1 becomes independent of incrustations through inevitable slag formation in the chambers 3 and 4 and thereby more reliable.
  • a mold arrangement 5 is attached to the multi-chamber furnace 1.
  • This mold arrangement 5 can be constructed from a mold, for example for casting strips, or a plurality of molds arranged next to one another, for example for multi-strand round casting.
  • An essential feature of the invention is that this mold arrangement 5 is mounted separately on an oven-independent support frame 10 and is non-positively connected to the multi-chamber furnace 1 via a compressible seal 9, with a flow connection between the mold arrangement 5 and the mold chamber 4 of the multi-chamber furnace 1.
  • a horizontally directed force acts between the mold arrangement 5 and the multi-chamber furnace 1, which results from a static contact force, reduced by the strand withdrawal force caused by a strand withdrawal device 8, from the positive connection of the mold arrangement 5 with the multi-chamber furnace 1.
  • a static contact force reduced by the strand withdrawal force caused by a strand withdrawal device 8
  • an average, essentially constant contact pressure is established.
  • the orthogonally acting, vertically directed weight of the multi-chamber furnace 1, which acts on the weighing device 6, remains unaffected by the process of pulling off the strand.
  • the weighing device 6 in the case of discontinuously intermittent strand withdrawal, is to be activated as a measuring element only when the strand withdrawal arrangement 8 is at rest.
  • the discontinuous intermittent strand withdrawal is formed by successive cycles with the successive phases train-pause-recoil-pause, where the pauses can last for several seconds.
  • the force between the mold arrangement 5 and the multi-chamber furnace 1 is free of dynamics and In this respect, the pause phases are particularly advantageously suitable for the precise determination of the degree of filling of the multi-chamber furnace 1.
  • the slight vertical movement of the multi-chamber furnace 1 required for the weighing process is irrelevant with varying degrees of filling, because the molten metal enters through the seal 9 into the mold arrangement and only gradually solidifies there.
  • the gross weight detected by the weighing device 6 is relieved by the essentially constant weight portion of the mold arrangement 5 and the variable weight portion of the strand 7, and thus the ratio of the fill weight of the molten metal to the gross weight is improved in favor of a higher measuring accuracy.
