GALVANIZING PROCESS AND ZINC ALLOY THAT MAY BE USED IN SAID PROCESS

摘要

A method for hot-dip galvanizing a series of individual steel objects. When all the objects to be galvanized contain at most 0.4 % of silicon, a zinc bath containing at least 0.005 % of silicon is used. When some of the objects contain over 0.04 % of silicon, a zinc bath containing at least 0.005 % of silicon as well as either 0.02-0.06 % of aluminium and 0.002-0.1 % of Ca, or 0.05-0.12 % of nickel, is used. A zinc-based alloy for compensating the galvanizing bath's consumption is also provided. The method may be used for coating steel.
