Method and device for directional crystallization of castings with oriented or monocrystalline structure

Abstract

The subject of the invention is a method and a device for oriented crystallization of castings with a oriented or monocrystalline structure. The method is based on the fact that during the transfer of the mould (1) containing the alloy from the heating zone (5) to the cooling zone (7), the temperature of the mould surface (1) above CLT1 and below CLT2 of the crystallization front (14) is measured in real time in at least two points, using contactless temperature meters (9a, 9b), with at least one of the lowest points is located in the cooling zone. The device has at least two contactless temperature meters (9a, 9b) installed in the chamber (2), at least one (9b), the lowest, located in the cooling zone (7).
