Continuous casting process and apparatus

摘要

In a continuous casting process the flow of molten metal is continuously fed into a mould to be further submitted to the action of the magnetic field generated by an electrical inductor and a stabilizing coil so that a column of molten metal is formed. The column of molten metal is then cooled to produce a continuous strand or ingot. The current supplied to the stabilizing coil has its phase lagging behind that of the current in the inductor with the phase angle between them ranging from 95 DEG to 165 DEG ; the amplitude of current in the stabilizing coil being 0.1 to 0.4 times the current amplitude in the inductor. Apparatus for performing the above-described continuous casting process comprises a mould formed by an electromagnetic inductor and a stabilizing coil from a nonmagnetic material in the form of a triangle arranged coaxially with the inductor and having its apex oriented inside the mould. The height of the triangle in cross-section of the stabilizing coil and the greater side of the triangle are in the ratio ranging from 0.7 to 0.96.
