TAPHOLE ASSEMBLY, METHOD FOR MANUFACTURING A TAPHOLE ASSEMBLY, AND METALLURGICAL FURNACE

摘要

The invention relates to a taphole assembly (1) for arranging in a taphole assembly opening (2) extending through a shell (3) and a refractory lining (4) of a metallurgical furnace (5) such as a pyrometallurgical furnace and for leading melt from the inside of the metallurgical furnace (5) to the outside thereof.The taphole assembly comprises a frame section of metal (6) to be arranged in the taphole assembly opening (2) extending through the shell (3) and the refractory lining (4) of the metallurgical furnace (5), and at least one refractory insert channel element (7) arranged in a seat (8) of the frame section of metal (6) and having a channel (9) for melt. The invention also relates to a method for manufacturing a taphole assembly and to a metallurgical furnace including a taphole assembly.
