Tapping and pouring system for molten metals

Abstract

System (2) for tapping a high-temperature molten material, especially a molten metal, from a bath (8) and pouring it into a mould, comprising a mobile container (6) capable of moving with respect to an element (26) in such as way as, on the one hand, said container (6) may be plunged into the bath (8) to take some liquid and, on the other hand, lift the container (6) above a particular level for forcing the liquid to fall down with gravity through an aperture (10) along the wall. The system (2) does not imply high costs and allows to pour accurate volumes of molten material.

Description

FIELD OF THE INVENTION [0001] The invention relates to a system for tapping and pouring high temperature molten material, comprising a first container and a second container capable of being introduced into the first container. PRIOR ART [0002] Many systems are known in the art to tap a particular amount or volume of high temperature molten material from a furnace and pour it, for instance into a mould for use in metal die-casting operations. [0003] One way to perform this operation is to make use of a ladle capable of being plunged into a bath of molten material, and further capable of taking out a particular amount of said molten material, transporting it for instance on top of a mould to be filled and pouring the molten material into the mould, either by tilting the ladle and by letting the molten material going through a spout or by opening a valve and letting the molten material to drain away through said valve. [0004] A system using the above principle is the “Hodler system”, ...

AI Technical Summary

Benefits of technology

The invention is a system for tapping and pouring high-temperature molten materials, such as molten metal, in a safe and accurate way. The system is compact, easy to install and maintain, and provides greater accuracy in the amount of molten material poured. It achieves this by using a second container that remains inside the first container and moves inside it to fill and then to pour the molten material. The second container is designed to prevent molten material from dripping and to minimize heat loss and safety hazards. The system is controlled by reversing or stopping the movement of the second container, and it is safer and more efficient than existing systems.

Problems solved by technology

This is a first advantage over the systems known in the prior art in which molten material often drips from the mobile container, which results in needless loss of material and safety problems.

This is the case of the “Hodler system” which also presents the propensity to cause important alteration to the molten material, due to the relatively long transportation time mainly outside the crucible.
