Definitions

  • the invention relates to a horizontal continuous casting mold, in particular for continuous steel casting, with an inlet part formed from refractory material on the inlet side, which can be connected in a sealing manner to a storage vessel for the melt, and with a continuous mold cavity which adjoins the inlet part and forms a continuous stepless cavity with internal cooling, preferably from Copper or a copper alloy formed mold main body.
  • a horizontal continuous casting mold without such radial cooling surfaces is known from DE-OS 25 20 091.
  • DE-OS 25 20 091 When operating a horizontal continuous casting mold, this However, due to the lack of a radial cooling surface, it is not possible to ensure the formation of the strand shell at a specific point in the longitudinal extent of the horizontal continuous casting mold, in particular in the inlet part.
  • the formation of the strand shell depends on a large number of parameters, such as the temperature of the melt in the storage vessel, the strand pull-out speed, the chemical composition of the melt to be cast and the heat removal due to the internal cooling of the main mold body.
  • the strand shell forms too early and grows beyond the inlet part, which can lead to tearing or tearing of the strand shell when the strand is pulled out. Furthermore, there is the risk that the strand shell only forms in the area at the connection point extending in the radial direction between the inlet part and the main mold body, as a result of which the connection point is affected by melt or melt can penetrate into a gap occurring at this connection point. which can lead to the destruction of the horizontal continuous casting mold or to tearing of the continuous shell.
  • the invention aims at avoiding these disadvantages and difficulties and has as its object to create a horizontal continuous casting mold of the type described in the introduction, in which the start of the continuous shell can be clearly defined at the desired location.
  • the inlet front part is provided with a heating device, and that between the heating device and the end of the strand lying in the pull-out direction Inlet part means for locating the strand shell formed, preferably a temperature measuring device, is provided.
  • the start of the strand shell growth can be determined in a transverse plane within the length of the inlet part.
  • the device for recognizing the strand shell enables the position of the start of shell growth to be monitored. As soon as this device gives a false indication, i.e. indicates the absence of a shell, the cooling in the mold wall is increased and the heat supplied via the heating device is reduced, etc. until the tray display device reports the presence of a tray again. If, according to the display of the device for locating the strand shell, this is already too strong - from which it follows that the beginning of the shell growth is too far on the input side of the horizontal continuous casting mold - the heat supplied via the heating device is intensified.
  • the inlet part has a sleeve provided in the pull-out direction of the strand, the wall thickness of which is less than the wall thickness of the front part of the inlet part, which sleeve is inserted into a recess provided on the end face of the main mold body and the outer surface of the sleeve on the annular Recess in the longitudinal direction of the horizontal continuous casting mold, the temperature measuring device is arranged within the sleeve net, wherein a heat insulating body is advantageously provided between the heating device and the temperature measuring device.
  • the heating device expediently being distributed over the length of the inlet front part and can be switched on and off individually arranged heater parts is formed.
  • the horizontal continuous casting mold With the horizontal continuous casting mold according to the invention, it is possible to continuously pull the strand out of the horizontal continuous casting mold, the horizontal continuous casting mold being drivable by means of an oscillating device. This eliminates the hitherto complicated, discontinuous pulling device for the strand.
  • the inlet front part expediently has a sliding surface on its peripheral outside and is surrounded by a pipe socket rigidly fastened to the storage vessel, the pipe socket advantageously having at least one circumferential groove on its mating sliding surface resting on the sliding surface of the inlet front part, into which at least one inert Gas supply line opens.
  • the circumferential groove is expediently filled with porous, refractory material.
  • Fig. 1 shows a schematic representation of a section through a horizontal continuous casting mold
  • Fig. 2 shows a diagram of the heat removal or the thermal conductivity for this mold
  • Fig. 3 shows a detail of Fig. 1 on a larger scale.
  • molten steel 3 is allowed to flow into a storage vessel 4, which is also called a distributor, via a pouring tube 2.
  • the storage vessel 4 is provided with a heating device (not shown) and has a heat-insulating jacket 5.
  • An outlet opening 7 for the molten steel 3 is provided on a vertical side wall 6 of the storage vessel 4, to which a short pipe socket 9 is connected by means of a flange 8.
  • a seal 10 is inserted between the flange 8 and the vertical side wall 6 of the storage vessel 4.
  • a first mold part which forms the inlet part 11 for the horizontal continuous casting mold, is inserted in the pipe socket 9 so as to be axially displaceable.
  • This inlet part 11 has an inner diameter 12 that is smaller than that (13) of the outlet opening 7 of the storage vessel 4.
  • the pipe socket 9 is provided on the inside with two circumferential grooves 15, which are filled with porous, refractory material 16 for the purpose of sealing. Lines 17 supplying inert gas open into these grooves 15.
  • the inlet part 11 which is formed from refractory material, is uncooled and essentially has two integrally connected parts 18, 19, namely an inlet front part 18 and a sleeve 19 extending the inlet front part 18.
  • the sleeve 19 has the same inner diameter 12 as the inlet front part 18; however, it is formed with a smaller wall thickness 20 than the inlet front part 18.
  • a In the inlet front part 18 are circumferential grooves 21 into which a heating device 22, such as. B. an electrically heated heating coil is used.
  • a heating device 22 such as. B. an electrically heated heating coil is used.
  • four heating coils are arranged one behind the other over the length 23 of the inlet front part 18. Each of the heating coils can be switched on and off and regulated separately from the others.
  • a device for locating the strand shell 24 formed by the molten steel is used, which is designed as a temperature sensor 25 in the exemplary embodiment shown.
  • a heat-insulating body 26 is provided between the temperature sensor 25 and the heating device 22, which ends at a distance from the inner surface 27 of the inlet part 11 and largely prevents the heating device from influencing the temperature sensor.
  • a second mold part adjoins the inlet part 11, specifically a mold main body 28 made of copper or a copper alloy, which is provided with channels for internal cooling.
  • This mold main body 28 has an annular recess 29 for receiving the sleeve 19, wherein in the case of assembled mold parts 11 and 28 the longitudinally extending outer surface 30 of the sleeve 19 touches the annular recess 29.
  • the radially directed connection surfaces 31, 32 of the recess 29 and the sleeve 19 rest against one another without a gap.
  • the inner surface 33 of the main mold body 28 has the same diameter 12 as the inner surface 27 of the inlet part 11, so that a stepless mold cavity 34 is formed by these two parts 11 and 28.
  • further mold parts for example aftercoolers 35 provided with internal cooling, one of which is shown in FIG. 1, can be connected to the main mold body 28 with or without a distance from the main mold body 28 extending in the longitudinal direction.
  • the temperature sensor 25 indicates a higher temperature as soon as steel melt 3 reaches the sleeve 19. In this case, the cooling of the main mold body 28 is intensified and the heating of the on running part 11, at least with the temperature sensor 25 adjacent heating coils reduced or switched off.
  • the strand shell 24 is in the range of 25 Tem p eraturmeßmonilers stronger and there is a temperature drop, which is registered by temperature sensor 25th In this case, the heating in the inlet part 11 is intensified and, if necessary, the cooling of the main mold body 28 is reduced at the same time.
  • the inlet part 11 have a low thermal conductivity and the mold main body 28 have a high thermal conductivity. Accordingly, the heat removal from strand heat in the area of the inlet part 11 is very low. It only rises sharply in the area of the relatively thin-walled sleeve 19, which slope 37 is responsible for the start of the formation of the strand shell 24. With the heating device installed on the inlet part 11, this increase 37 of the heat removal can be moved in the direction of the longitudinal axis of the horizontal continuous casting mold.
  • the invention is not limited to the embodiment shown in the drawing, but can be modified in various ways.
  • other devices for locating the strand shell 24 formed can be provided, such as. B. strain gauges or ultrasonic transmitters and receivers.
  • the heating device of the inlet front part can also be formed by a heating coil provided spirally in the inlet part 11.
  • the invention can also be implemented for differently shaped cross-sectional shapes of the mold cavity 34.
