Abstract (en)

[origin: EP1066898A1] Initial temperature of melt in the distributor (302) is measured at a first casting speed. The first heat loss rate is measured from melt in the distributor, and also during its residence time between distributor and the casting level in the casting mold. An equivalent liquidus temperature T'liq + 0 is determined as the limiting temperature which will be reached, taking into account the initial liquidus temperature Tliq of melt already in the casting region of the mold, and the given casting speed. Isotherms of the equivalent liquidus temperature T'liq + x are determined as a function of superheating temperatures x, with x greater than zero, the isotherms each relating melting temperatures in the distributor and casting speeds. The initial continuous casting speed is matched to a desired continuous casting speed inside a given window of isotherms, with the lowest boundary lying above the equivalent liquidus temperature curve T'liq + 0. An Independent claim is included for the corresponding casting system.
