Abstract
The invention relates to a method for the manufacture of a composite cooling element for the melt zone of a metallurgical reactor, whereby the element is manufactured by attaching ceramic lining sections to each other by copper casting and forming at the same time a copper plate equipped with cooling water channels behind the lining. The invention also relates to composite cooling elements manufactured by this method.
Claims38
A method for manufacturing a composite cooling element for the melt zone of a metallurgical reactor, comprising:
- placing ceramic lining sections in a framework made of steel, and
- casting molten copper over the ceramic lining sections and the framework to join the ceramic lining sections and the framework to each other and to form a copper plate over the ceramic lining sections,
- whereby the framework is disposed between the ceramic lining sections at an interior surface of the composite cooling element and the copper plate is outward of the ceramic lining sections.
A composite cooling element for the melt zone of a metallurgical reactor, the cooling element having an interior surface and comprising
- ceramic lining sections,
- metal disposed between the ceramic lining sections, and
- a copper plate outward of the ceramic lining sections,
- wherein the metal that is between the ceramic lining sections at the interior surface of the cooling element is steel and the metal that is between the ceramic lining sections outward of the steel is cast copper that attaches the ceramic lining sections to each other and forms the copper plate.
A composite cooling element made by a method that comprises:
- placing ceramic lining sections in a framework made of steel, and
- casting molten copper over the ceramic lining sections and the framework to join the ceramic lining sections and the framework to each other and to form a copper plate over the ceramic lining sections,
- whereby the framework is disposed between the ceramic lining sections at an interior surface of the composite cooling element and the copper plate is outward of the ceramic lining sections.
