A method and a device for admixture of powder in a liquid, whereby the method comprises that the liquid in a supply (), influenced by underpressure in a crucible () to which the liquid is to be transferred, flows through a drain tube () out of the supply (), the powder is dosed from a powder receptacle () and is driven by a gas, and the mixture of powder and gas is added to the liquid in the drain tube () and mixed therewith, whereupon the mixture flows into the crucible (). The device comprises a supply () from which the liquid may flow and a receptacle () with powder, whereby a drain tube () connects the supply () with a receiving receptacle () which can be held at an inner underpressure. A device () for supply of a driving gas for the powder is connected to a mixing chamber () at an outlet from the powder receptacle (), while the mixing chamber () is connected to the drain tube () for supply of powder to the liquid flowing in the drain tube.

Method and device for admixture of powder in a liquid

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

Method and equipment for continuous or semicontinuous casting of metal

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.

Machine for vertical casting of metal

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.
