Plate cooler for metallurgical furnaces, blast furnaces, direct reduction reactors and gassing units provided with a refractory lining particularly for the iron and steel industry

A plate cooler for metallurgical furnaces, including blast furnaces, direct reduction reactors and gassing units lined with a refractory lining, formed by a process comprising the steps of:

• arranging pipe parts in a plurality of rows next to each other corresponding to a width of the plate cooler to form a complete pipeline;
• welding parts of the complete pipeline together to form a prefabricated pipeline said pipe parts including at least one of copper pipe sockets, copper pipelines, copper pipe bends and bent copper pipes;
• placing the completely prefabricated pipeline into a casting mold, fixed in a drag box;
• pouring molten copper around said prefabricated pipeline, so that the prefabricated pipeline is embedded in a copper plate after the solidification of the melt wherein said pipe parts and said melt when solidified comprise cast copper or a low-alloy copper alloy;
• providing a plurality of copper plates positioned adjacent to each other to form a circular cooling ring within the metallurgical furnace.
