Ingot mould for the continuous casting of liquid metal equipped with means for controlling the solidification of the liquid metal

摘要

Ingot mould for the continuous casting of liquid metal, including a first wall (1) and a second wall (2) between which are provided channels (4) inside which a liquid for cooling the bath (5) of liquid metal can circulate, characterised in that it comprises means (6, 7) for locally modifying the flow conditions (regime) of the cooling liquid at the level of the surface of the bath of liquid metal in order to limit the heat flow (flux) extracted from the bath at this level. These means may, for example, be fins (6) mounted so as to tilt on horizontal shafts (7) in the channels (4), substantially below the level of the meniscus (5a) of the liquid metal. IMAGE
