A METHOD FOR MANUFACTURING A METAL SHEET WITH A ZNAL COATING AND WITH OPTIMISED DRYING CORRESPONDING METAL SHEET PART AND VEHICLE

摘要

In the present method at least one of the equations (A B) is fulfilled where: Z is the distance between the metal sheet (1) and the nozzle (17) in the main discharge direction (E) Z being expressed in mm d is the mean height of the outlet (25) of the nozzle (17) in the direction (S) of travel of the metal sheet (1) in front of the nozzle (17) d being expressed in mm V is the speed of travel of the metal sheet (1) in front of the nozzle (17) V being expressed in m.s P is the pressure of the drying gas in the nozzle (17) P being expressed in N.m and fO is the volume fraction of oxygen in the drying gas.
