Abstract

Способ производства металлического слитка путем использования электронно-лучевой печи, включающей в себя электронную пушку, способную управлять положением облучения электронным лучом, и ванну, которая накапливает расплавленный металл из металлического сырья, в котором в последующей по течению области между предшествующей по течению областью, в которой металлическое сырье подается на поверхность расплавленного металла, и первой боковой стенкой линия облучения располагается так, чтобы блокировать часть сливного носка, и так, чтобы две концевые части линии облучения располагались в непосредственной близости от боковой стенки ванны. Первый электронный луч излучается на поверхность расплавленного металла вдоль линии облучения, и первый электронный луч излучается вдоль линии облучения. За счет этого температура поверхности (T2) расплавленного металла вдоль линии облучения делается более высокой, чем средняя температура (T0) всей поверхности расплавленного металла в ванне, и в наружном слое расплавленного металла формируется поток расплавленного металла от линии облучения в противоположную от первой боковой стенки сторону.A method for manufacturing a metal ingot by using an electron beam furnace including an electron gun capable of controlling an electron beam irradiation position, and a bath that accumulates molten metal from a metal raw material, in which, in the downstream region between the upstream region, in which the metal raw material is fed to the surface of the molten metal, and the first side wall of the irradiation line is located so as to block part of the drain spout, and so that the two end parts of the irradiation line are located in close proximity to the side wall of the bath. The first electron beam is radiated to the surface of the molten metal along the irradiation line, and the first electron beam is radiated along the irradiation line. Due to this, the surface temperature (T2) of the molten metal along the irradiation line is made higher than the average temperature (T0) of the entire surface of the molten metal in the bath, and in the outer layer of the molten metal a flow of molten metal is formed from the irradiation line in the opposite direction from the first side wall .
