Method and system for galvanizing by plasma evaporation

摘要

The invention relates to a method and a system for the plasma treatment of successive substrates comprising one or more steel products in which the substrates are transported, one after another, through at least one plasma treatment zone, characterized in that the electric power for generating the plasma in the treatment zone is varied according to the area of the substrate is present in this treatment zone when the substrate is running through this zone.

主权项

1. A method for the plasma treatment of successive substrates, wherein each substrate comprises one or more steel products, comprising transporting the substrates one after the other through at least one plasma treatment zone (3,4,5), varying the electrical power supplied to generate the plasma in the treatment zone (3,4,5) progressively and proportionally according to the area of the substrate present in the treatment zone (3,4,5) while the substrate is entering the treatment zone and while the substrate is leaving the treatment zone when the substrate is passing through the treatment zone (3,4,5), wherein the substrates are moved along a straight path through the treatment zone.
