Abstract
Installation for the hot-metallizing of small items of steel or cast iron, comprising a continuous annealing furnace (1) with a furnace chamber (2) having regulatable temperature zones, a feeding device (3) for conveyor boxes (4) to accommodate the metal parts to be metallized, conveying devices (6, 9) for transporting the conveyor boxes (4) through the annealing furnace (1) and back to a discharge device (10), a vacuum inlet gate (5), and a vacuum outlet gate (7) which are under a protective gas atmosphere. A device (11) is arranged within the vacuum outlet gate (7) for emptying the conveyor boxes (4) into circulating dip baskets (13) of a metallizing plant (12) connected to the continuous annealing furnace (1), comprising a ceramic-lined, inductively heated metal bath (14). Lifting units lower the dip baskets (13) from a circulating position (13a) into a dipping and filling position (13c) into the metal bath (14) and lift the baskets (13 ) into a position (13e) above the metal bath (14). The annealing furnace (1) has a cooling zone (8), the furnace chamber (2) and the cooling zone (8) containing a pusher device (6, 9) for the cyclic feeding of the conveyor boxes (4).
