Abstract
Hot coating of a steel sheet (1) is carried out by dipping the sheet in a bath of liquid metal (5) utilizing an inlet tube (5) at least partly under a controlled oxidizing atmosphere. A method for the hot coating of a steel sheet (1) by dipping in a bath of liquid metal (5) utilizing an inlet tube (5) at least partly under a controlled oxidizing atmosphere consists of: (a) passing the sheet through a first zone (9) in which the atmosphere of hydrogen and water vapor is non-oxidizing with respect to iron and such that P(H2)/P(H2O) is greater than 70 and P(H2)) is less than 264 ppm; (b) and passing the sheet through a second zone (10) in which the atmosphere of hydrogen and water vapor is oxidizing with respect to the liquid metal and some alloying elements of the steel and such that the H2 content is less than 1% by volume. An Independent claim is also included for the inlet tube under a controlled atmosphere for putting this method into service and incorporating a means for separating the two zones.
