When performing galvanization a container is used which is open at the top and the outer wall (1) of which is perforated to permit the passage of molten zinc. A central rod (6) extends from the container bottom (13), a sliding body (5) being displaceable about this rod and joined to the outer wall (1). The rod (6) is also provided with a connection (12) to lifting gear. A locking device (9) is arranged to effect locking between the rod (6) and sliding body (5) when the bottom (13) and the outer wall (1) are in contact with each other. According to the invention the outer wall (1) is in the shape of a truncated cone, diverging towards the bottom (13) and the container is preferably provided with an inner wall (15, 17) permanently joined to the bottom (13). |
