Continuous vertical metal casting process using electromagnetic fields and casting installation for its execution

摘要

"CONTINUOUS VERTICAL METALING PROCESS OF METALS THAT USE ELECTROMAGNETIC FIELDS AND INSTALLATION OF ENGINEERING FOR ITS EXECUTION". According to the process, the liquid metal meniscus present inside the ingot mold is jointly subjected to the action of an alternating axial magnetic field that tends to give it a general domed shape and to the action of a continuous transversal magnetic field intended to calm the superficial agitation of the meniscus. The execution installation comprises an ingot (1) of cooled joined plates (2,3 and 4,5) for the casting of metal plates, an alternating current coil (17) that surrounds the ingot at the level of the meniscus (12) of liquid metal to produce an axial field, collinear to the casting axis (11), and a continuous magnetic field inductor that crosses the larger plates of the ingot mold at the meniscus level (12) perpendicular to the casting axis.
