Abstract
Abstract AN APPARATUS FOR CONTINUOUS AND SEMICONTINUOUS CASTING OF METALS PERMITTING INGOTS TO BE PRODUCED WITHOUT ANY SURFACE DEFECTS DUE TO THE FACT THAT A MAGNETIC FIELD IS PROVIDED IN THE APPARATUS DISTRIBUTED IN THE AXIAL DIRECTION SO AS TO ENSURE THE QUALITY OF THE HYDROSTATIC AND ELECTROMAGENTIC PRESSURES. THIS IS ACHIEVED BY MEANS OF AN ELECTROMAGNETIC SCREEN MOUNTED WITHIN THE RING-SHAPED INDUCTOR. THE ELECTROMAGNETIC SCREEN CONSISTS OF A CLOSED RING OF A NON-MAGNETIC METAL WHOSE THICKNESS INCREASES UPWARDLY WHILE THE LOWER EDGE IS DISPOSED AT APPROXIMATELY HALF OF THE HEIGHT OF THE INDUCTOR.
