Definitions

  • the known continuous casting molds whether designed as Wanderkokille, such as the 'Twin Roller' after a 19th century Bessemer patent, or as a stand mold, consist of a copper wall, the back is cooled with water through a water distribution box.
  • the chill 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 factors.
  • the water Describing the rest of the water cycle, the water is in one Heat exchanger (18), which is controllable in its performance, to the desired constant Inlet temperature (6) cooled and with the help of a pump station (19) with a desired pressure (9) supplied to the mold again.
  • This water cooling system is also at risk, at high casting speeds of 10 - 15 m / min at the 'cold face' of the mold wall (20) for gas film formation to get there the evaporation point at a given pressure by too high a temperature is exceeded in the heat transfer region of the copper wall.
  • the invention is based on the object, a generic method and to provide a device with which the mold or continuous casting operation to improve.
  • Part 3 b) provides for the inventive solution the variable inlet temperature a constant outlet temperature of 40 or 30 ° C depending on the Copper plate thickness for two different casting powders A and B represent.
  • the essential feature of the invention is that at the outlet of the Kokillenwassers from the mold, a two-way valve (23) is arranged, with the help a temperature sensor operating at a controlled constant temperature (24)
  • a temperature sensor operating at a controlled constant temperature (24)
  • the water distribution between hot mold water (25) and (About a heat exchanger (26)) cooled Kokillenwasser (27) made so is that the outlet temperature (24), for example, at changing casting speeds (4) remains constant.
  • the invention makes it clear that with the introduction of a thermostat (24) on the Kokillenwasserauslaufseite to compensate for a two-way valve (23) the 'hot face'-temperature of the mold plate constant regardless of the casting conditions can be held.
  • This solution ensures that the heat flow remains undisturbed and constant over the mold width that the casting powder lubrication remains constant, the life of the mold plates on their skin temperature (22) remains controlled and the best conditions for the strand surface even at high casting speeds of up to 15 m / min are given.
