Abstract
Metal particles are remelted in a fusion zone by electron beam bombardment and formed in a continuous casting mould. Furthermore, PA1 (a) the metal particles are evenly distributed over the horizontally positioned floor of a fusion ladle, PA1 (b) the metal particles are joined together into a plate-shaped structure by means of the electron beam, whereafter PA1 (c) the floor of the fusion ladle is moved into a position inclined in relation to the horizontal, PA1 (d) the electron beam is guided upwards over the sloping, plate-shaped particle structure so that this is firstly preheated and fused directly thereafter, while PA1 (e) the molten metal running over the lower part of the floor is simultaneously kept liquid by electron beam bombardment, whereafter PA1 (f) the electron beam is guided back downwards over the sloping floor of the fusion ladle, and PA1 (g) the floor of the fusion ladle is returned to the horizontal starting position and is once again charged with metal particles according to feature (a).
