Abstract: The invention relates to a casting mould for manufacturing of a cooling element for a pyrometallurgical reactor, wherein the casting mould is at least partly cooled and lined with a material that can withstand high temperatures. The invention also relates to the cooling element made in the mould, inside which cooling pipes made of nickel copper are placed during fabrication.

Abstract: A method for manufacturing a cooling element comprising a housing part and ceramic lining elements arranged on the housing part surface. The ceramic lining elements (2) are connected to the element housing part (1) by using in the joint between the lining elements and the housing part a soldering/brazing agent, wherein at least the junction area is heated at least up to the melting temperature of the soldering/brazing agent, so that there is created a joint with a good thermal contact with the element housing part (1) and a ceramic lining element (2). The invention also relates to a cooling element.
