Laboratory Experiments for Studying the Surface Preparation and Annealing Processes before Continuous Hot Dip Galvanizing

摘要

The coated product market is a highly quality exigent market which has been developing for decades. The technological process of galvanizing starts with a thermal cleaning in a continuous annealing furnace. Therefore the understanding of the processes which take place before dipping requires laboratory experiments modelling the oxidation and reduction of the base metal. Some of the presented experiments are thermogravimetric oxidation and reduction tests, others are laboratory trials carried out in special experimental furnace.
