Definitions
- the invention relates. a method for measuring and regulating temperature and quantity of per unit time by water-coolable, especially from each other independent mold walls made of cooling water flowing through copper plates a continuous casting mold, the cooling water temperature a mold wall in at least two places in the area of the drain openings a copper plate and the associated water tank is measured.
- the process is operated in such a way that cooling water inlet holes interacting the water supply in cooling channels of the mold wall form while the sum of drain holes of the cooling channels taken together form the water outlet, the inlet temperature of the cooling water, the difference between the inlet and outlet temperatures determined and from the amount of cooling water per unit of time partial integral heat dissipation from a mold or from a Mold wall area determined and a temperature profile created and temperature profiles obtained in time intervals with each other compared and partial inequalities through partial quantity corrections of the cooling water are balanced.
- the flow velocity is usually used and the water pressure on the outlet side of the Water cooling system chosen so that for the hottest point of the The temperatures on the surface of the cooling channel below the mold The boiling temperature of the water is in accordance with the outlet pressure.
- the additional registration is based on the task of the procedure of the main patent (patent application 197 22 877) further train and improve and through targeted cooling a Equalization of the temperature distribution in the area of the bath level of molds, in particular molds for casting thinner Slabs to achieve.
- the object is achieved with the invention in that the Flow rate and the water pressure of the cooling system so be set so that the lowest temperature in the range of Water outlet side or the water outlet opening of a copper plate is at the boiling point limit, and that for everyone higher temperatures a bubble evaporation during supercooled boiling of the cooling water is excited.
- the measure Be made use of that the flow rate and the Coolant pressure in the cooling channels can be set constantly, such that an increased heat load by a corresponding increased bubble evaporation is compensated.

Description
Claims (2)
- Verfahren zum Messen und Regeln von Temperatur und Menge des pro Zeiteinheit durch wasserkühlbare, insbesondere voneinander unabhängige Kokillenwände aus Kupferplatten durchströmenden Kühlwassers einer Stranggießkokille, wobei die Kühlwassertemperatur einer Kokillenwand an wenigstens zwei Stellen im Bereich der Ablauföffnung einer Kupferplatte und dem zugeordneten Wasserkasten gemessen wird,
dadurch gekennzeichnet, daß die Strömungsgeschwindigkeit und der Wasserdruck des Kühlsystems im Bereich der Wasser-Austrittsseite bzw. der wasser-Ablauföffnungen einer Kupferplatte so eingestellt werden, daß die niedrigste Temperatur im Bereich des Wasserauslaufs an der Grenze der Siedetemperatur liegt, und daß für alle höheren Temperaturen eine Blasenverdampfung beim unterkühlten Sieden des Kühlwassers angeregt wird. - Verfahren nach Anspruch 1,
dadurch gekennzeichnet, daß die Strömungsgeschwindigkeit und der Kühlmitteldruck in den Kühlkanälen konstant eingestellt werden, derart, daß eine erhöhte Wärmebelastung durch eine entsprechend erhöhte Blasenverdampfung kompensiert wird.
