Definitions

  • the known continuous casting molds whether designed as a traveling mold, such as the 'twin roller' according to a 19th century Bessemer patent, or also as a stand mold, consist of a copper wall, the back is cooled with water via a water distribution box.
  • the mold cooling water (10) assumes a higher temperature T M out (11) with increasing casting speed.
  • the temperature difference (13) between the constant inlet temperature (16) and the variable outlet temperature (11) is a function of the above-mentioned influencing variables.
  • the outlet temperature (11) or the temperature difference (13) and. Will increase with increasing casting speed from VC 1 (4.1) to VC 2 (4.2) thus the mold skin temperature (14) from T 1 (14.1) to T 2 (14.2) and the energy under the energy lobe (15) from (15.1) to (15.2).
  • the water becomes one Heat exchanger (18), which is controllable in its output, to the desired constant Inlet temperature (6) cooled and with the help of a pump station (19) a desired pressure (9) of the mold again.
  • This water cooling system also runs the risk of high casting speeds of 10-15 m / min to reach the 'cold face' of the mold wall (20) for gas film formation, because the evaporation point at a given pressure due to an excessively high temperature is exceeded in the heat transfer area of the copper wall.
  • the invention has for its object a generic method and to create a device with which the mold or continuous casting operation can improve.
  • Part 3 b) provides the variable inlet temperature for the inventive solution a constant outlet temperature of 40 or 30 ° C depending on the Copper plate thickness for two different casting powders A and B.
  • the essential feature of the invention is that at the outlet of the mold water from the mold, a two-way valve (23) is arranged, which with the help of a temperature sensor which is controlled to a constant temperature (24) is set, the water distribution between hot mold water (25) and (via a heat exchanger (26)) cooled mold water (27) is that the outlet temperature (24), for example, with changing casting speeds (4) remains constant.
  • drawing 3 a leaves the completely different situation of the known one Detect cooling.
  • the outlet temperature (11) increases with the casting speed at constant Inlet temperature (6) the outlet temperature (11) and thus the 'hot face' temperature (14), which compares the disadvantages described above well reveal.
  • the function shows that for constant outlet temperatures (24.1) and (24.2) or 'hot face' temperatures (22) and changing copper plate thicknesses (7) as well as casting powder A and B, the inlet temperature T M in (28 ) is changed functionally.
  • the invention makes it clear that with the introduction of a thermostat (24) on the Chill water outlet side for regulating a two-way valve (23) the 'hot face 'temperature of the mold plate is constant regardless of the casting conditions can be held.
  • This solution ensures that the heat flow Undisturbed and constant over the width of the mold, the powder lubrication remains remains constant, the service life of the mold plates above their skin temperature (22) remains more controlled as well as the best conditions for the strand surface even at high casting speeds of up to 15 m / min.
