Abstract

Sposób polega na tym, że w trakcie przemieszczania się formy (1) ze stopem ze strefy ogrzewania (5) do strefy chłodzenia (7), w czasie rzeczywistym mierzy się temperaturę powierzchni formy (1) powyżej CLT1 i poniżej CLT2 frontu krystalizacji w co najmniej dwóch punktach, przy użyciu bezkontaktowych mierników temperatury (9a, 9b), przy czym przynajmniej jeden z punktów, leżący najniżej, znajduje się w strefie chłodzenia. Urządzenie ma w komorze (2) zainstalowane są co najmniej dwa bezkontaktowe mierniki temperatury (9a, 9b), przy czym co najmniej jeden (9b), położony najniżej, znajduje się w strefie chłodzenia (7).The method consists in the fact that during the movement of the mold (1) with the melt from the heating zone (5) to the cooling zone (7), the temperature of the mold surface (1) above CLT1 and below CLT2 of the crystallization front is measured in real time at least two points, using non-contact temperature meters (9a, 9b), with at least one of the lowest points in the cooling zone. The device has in the chamber (2) installed at least two non-contact temperature meters (9a, 9b), at least one (9b), the lowest, is located in the cooling zone (7).
