<p>For an assembly for sealing a shaft (16), which shaft is arranged in a container (12) filled with a liquid melt (10) consisting of aluminum or an aluminum alloy, passes through an opening (20) in a wall (18) of the container (12), and rotates about a shaft axis (x) and/or moves back and forth in the direction of the shaft axis (x), at least one annular sealing element (44) encompasses the shaft (16). The at least one sealing element (44) is made of carbon, a ceramic material, or a metal material and is arranged outside of the container (12), and the shaft (16) is provided with a coating (60) made of carbon, a ceramic material, or a metal material in the encompassing area of the at least one sealing element (44), wherein the wear resistance of the coating (60) on the shaft (16) is the same as or higher than the wear resistance of the at least one sealing element (44).</p> |
