Problems solved by technology

However, the furnace walls will one day become thinner, possibly causing the molten metal to come into contact with the copper cooling elements
Usually, cooling elements made of copper cannot withstand the action of molten metal in direct molten contact, especially if the molten metal is flowing or disturbed, however it begins to melt, which causes an overload of the cooling capacity of the element and consequent damage
This can even lead to significant financial losses

Embodiment Construction

[0014] A cooling element according to the invention, in particular designed for metal manufacturing processes, in relation to furnaces or the like, comprises a housing 1 provided with a channel system 2 for the circulation of cooling water. According to the invention at least that part of the surface of the cooling element which may come into contact with the molten metal is of steel. The cooling element can be entirely made of steel, or its housing part can be made of copper, in which case at least one steel part is provided on the housing surface.

[0015] The cooling element according to the drawing comprises a housing 1 provided with a channel system 2 for the circulation of cooling water (FIG. 3). For example, usually the housing 1 of the cooling element is made of copper. The housing 1 of the cooling element is preferably produced by casting, for example drawing casting. In the housing 1 there is a channel system 2 for the circulation of the coolant. Usually the chann...

Abstract

The invention relates to a cooling element, in particular to be used in connection with furnaces and the like related to metal production processes, said element comprising a housing (1) provided with a channel system (2) for cooling water circulation. At least part of the cooling element surface that may get into contact with molten metal is made of steel.

Description

technical field [0001] The invention relates to a furnace related to metal production processes, comprising a cooling element comprising a casing made of copper provided with a system of channels for the circulation of cooling water, in which a Steel elements are attached to the side shells, each set in a groove in the shell so that they come into contact with the molten metal. Background technique [0002] Regarding furnaces used for industrial purposes, especially for the production of metals, such as flash smelting furnaces, blast furnaces, electric furnaces or other metallurgical reactors, cooling elements, usually mainly copper, are used. Usually these cooling elements are cooled with water, so there is a channel system for the cooling water, where heat is transferred from the refractory bricks in the furnace to the cooling water through the cooling element housing. The working conditions are severe, where the cooling elements are subjected to strong corrosive or abras...
