Abstract

A hot-dip metallizing apparatus (1) for continuously metallizing metal strip (12) comprises a container of diameter (D) and depth (T). The zinc melt (9) in the container is heated and agitated by an induction coil system (5). Hard zinc deposits (10) comprising iron, zinc, aluminium and silicon form in the zinc melt (9) and, if they reach the metal to be metallized, will adversely affect the product by pitting. To avoid this, the container dimensions are chosen so that its depth (T) is at least as great as its diameter (D). The induction coil system (5) is also divided into superposed component coils (6, 7, 8). During operation the lowermost coil (8) associated with the bottom of the container is not energized with alternating current, so that hard zinc deposits (10) can accumulate in the bottom of the container (2), since agitation is brought about only by the upper coils (7, 6) in the middle and top part of the container. When the hard zinc deposits have to be removed, the lowermost coil (8) can also be energized, so that the deposits can travel upwards from the container bottom. <IMAGE>
