Abstract
A method and an apparatus for coating metal strip, particularly cold-rolled steel strip, with a coating metal which is in the molten state. The metal strip is heated and annealed in a heating furnace and subsequently the required strip temperature and surface properties are adjusted in a cooling zone. The strip is conducted through a coating container and, following the coating container in strip pulling direction, the coating metal thickness and the solidification process are controlled by a gas-operated stripping device. The operating gas for the stripping device is preheated in a partial area of the cooling zone of the heating furnace.
