Abstract
A mold for electromagnetic continuous casting has a supporting frame for an induction coil and a cooling device which features at least one nozzle for directing a liquid coolant onto the surface of the ingot being cast. A section (15) is provided in line with the stream of liquid coolant emerging from at least one nozzle such that it provides an impacting surface for deflecting the stream of coolant onto the surface of the ingot.
Claims19
A method for electromagnetically continuously casting molten metal comprising:
- providing a support frame;
- providing an inductor associated with said support frame for applying a magnetic field to the molten metal to define a mold cavity;
- providing coolant supply means including at least one discharge nozzle for feeding a coolant stream to a first location of impingement on a surface of a cast ingot;
- and
- continuously casting metal into said mold cavity to produce a continuous casting;
- providing deflecting means separate from said coolant supply means and remote and downstream of said at least one discharge nozzle for controlling the position and angle at which the coolant stream is applied to the surface of said continuous casting by deflecting and redirecting said coolant stream emanating from said at least one discharge nozzle onto a surface of said continuous casting at a second location of impingement, taken along a direction of casting withdrawal, relatively above said first location of impingement of a stream emanating from said discharge nozzle;
- and deflecting and redirecting said coolant stream from said first location to said second location.
A mold for electromagnetic continuous casting molten metal comprising a support frame, an inductor coil associated with said support frame for applying a magnetic field to define a model cavity and coolant supply means associated with said inductor including at least one discharge nozzle for feeding a coolant stream from said coolant supply means to a first location of impingement on a surface of a cast ingot for solidifying said molten metal;
- the improvement comprising deflecting means separate from said coolant supply means and spaced apart from and downstream of said at least one discharge nozzle for deflecting and redirecting said coolant stream emanating from said at least one discharge nozzle onto a surface of an ingot being cast at a second location of impingement taken along a direction of casting withdrawal, relatively above said first location of impingement of a stream emanating from said discharge nozzle.
