Abstract: A method and equipment for continuous or semi-continuous casting of metal, in particular directly-cooled (DC) casting of aluminium, including at least one mould (3) with a mould cavity (11) that is provided with an inlet (4) linked to a metal store and an outlet with devices (27) for cooling the metal so that an object in the form of an extended string, rod (25) or bar is cast through the outlet. The metal is supplied to the mould (3) in such a way and with such regulation that the metallostatic pressure in the contact point (solidification zone) against the mould wall is virtually zero during casting.

Abstract: A machine for vertical casting of metal, including a frame on which casting molds can be mounted and through which cooling water can be supplied during casting. The frame includes a horizontal cantilever arm protruding from a support and being journalled in the support with one end, for vertical pivoting of the frame, said support being rotatable about a vertical axis for horizontal pivoting of the frame.

Abstract: Casting wheel for continuous casting of metal, including a casting groove for the metal along its periphery, for supply of metal melt while the wheel rotates in a vertical plane, said wheel cooperating with an endless belt that runs together with the wheel during a part of the rotation of the wheel and covers the groove while forming a casting chamber. The wheel comprises two wheel rings mounted for rotation about axes that are set at an angle between each other, whereby the width of the groove varies during rotation of the wheel. The wheel rings defines a first groove wall and the groove bottom, while the other wheel ring defines the other groove wall, which moves axially relatively to the first groove wall, along the groove bottom.

Abstract: A machine for vertical casting of metal, including a frame on which casting can be mounted and through which cooling water can be supplied during casting. The frame includes a horisontal cantilever arm protruding from a support and journalled in the support with one end, for vertical pivoting of the frame, said support being rotatable about a vertical axis for horisontal pivoting of the frame.

Abstract: Casting equipment for continuous or semi-continuous direct chill casting of metals, in particular the casting of billets or ingots of aluminum, has a mold cavity (4) with an inlet (2) that is upwardly open, an intermediate, inwardly facing and heat insulated overhang or hot-top (8), and an outlet with a vertically movable supporting device (5). A slit (10) supplies water to cool the molted metal. The wall in the mold cavity is wholly or partly constituted by a permeable material, whereby oil and/or gas are supplied through the permeable material to form an oil and/or gas layer between the metal and the wall of the mold to prevent the metal from coming into direct contact with the wall of the mold. The oil and gas are supplied separately through two independent, and, by means of a sealing element (14) or the like, physically separated rings or wall elements (12, 13).

Abstract: A device for the discontinuous charging of molten metal into a vacuum chamber which is continuously held under vacuum includes a charging vessel or tundish on which is disposed a fixed transfer pipe so positioned that the tundish can be rotated about the axis of the pipe to such an extent that the pipe's input orifice is lifted above the surface of the metal flow in the tundish, while at the same time the pipe is withdrawn from the vacuum chamber. The chamber is sealed with a plate valve.
