Taphole assembly, method for manufacturing a taphole assembly, and metallurgical furnace

Metallurgical furnace such as a pyrometallurgical furnace, wherein the metallurgical furnace comprises

• a shell and a refractory lining,
• a taphole assembly opening extending through the shell and the refractory lining of a metallurgical furnace, and
• a taphole assembly for leading melt from the inside of the metallurgical furnace to the outside of the metallurgical furnace arranged in the taphole assembly opening
• characterized
• by the taphole assembly comprises a frame section of metal and at least one refractory insert channel element arranged in a seat of the frame section of metal and having a channel for melt
• by the frame section of metal comprises at least two identical frame parts of metal, and by said at least two identical frame parts of metal are connected such that a connection face between said at least two identical frame parts of metal cuts the seat for the refractory insert channel element such that an identical longitudinal groove is formed in each of said at least two identical frame parts of metal.

A method for manufacturing a taphole assembly for arranging in a taphole assembly opening extending through a shell and a refractory lining of a metallurgical furnace such as of a pyrometallurgical furnace and for leading melt from the inside of the metallurgical furnace to the outside of the metallurgical furnace,

• characterized
• by the method comprises a first providing step for providing a frame section of metal to be arranged in a taphole assembly opening extending through a shell and a refractory lining of a metallurgical furnace,
• by providing the frame section of metal with a seat for at least one refractory insert channel element,
• by the method comprises a second providing step for providing at least one refractory insert channel element having a channel for melt,
• by the method comprises arranging said at least one refractory insert channel element having a channel for melt in the seat of the frame section of metal,
• by providing in the first providing step a frame section of metal comprising at least two identical frame parts of metal, and
• by providing the frame section of metal with a seat for at least one refractory insert channel element so that said at least two identical frame parts of metal are connectable such that a connection face between said at least two identical frame parts of metal cuts the seat for the refractory insert channel element such that an identical longitudinal groove is formed in each of said at least two identical frame parts of metal.
