Comparison between HNX/pure hydrogen annealing and continuous/ batch annealing*
Comparaison entre recuits sous HNX/hydrogène pur et continu/ base
The basic difference between continuous annealing and batch annealing conies from the special geometry of the steel strip, which has direct influence on the throughput parameters. The switch from an HNX to a straight hydrogen atmosphere in batch annealing leads to improve productivity, surface cleanliness and homogeneity of the mechanical characteristics. These benefits offset the extra cost of using straight hydrogen.
Subject of lecture at the French-German Cold Rolling Meeting, ATS-VDEh (Paris, September 20-21, 1990). The authors are indebted to the different research teams working on this subject at Irsid for their encouragement and fruitful discussions during the preparation of the manuscript. Particular thanks are addressed to the personnel of the Surfaces and Physical Metallurgy Departments at Irsid St-Germain.
