PROCESS FOR COATING THE SURFACE OF ELONGATED MATERIALS

摘要

(5?) In a process for coating the surface of elongated material, the materials go through a container for the molten coating material without reversing their direction. The container has a through channel surrounded by an electric field in which an electromagnetic force is generated and the dwelling time of the strip in the melt can be controlled independently from the strip advance speed. In order to improve the conventional strip coating process so that favourable intermediate layers that ensure a good adherence and a good plasticity of the coating can be achieved, the molten coating material is continuously moved against the surface of the elongated material and is circulated in an atmosphere free from atmosphere oxygen while the hank-shaped goods so through the container. A device used therefor is characterized in that a pre-melting container (12) is associated to the coating container for the molten coating material (2), and that the melt (2) can circulate between the pre-melting container (12) and the coating container (1) in an atmosphere free from atmosphere oxygen.
