Abstract

Recent investigations have shown that an iron oxidation / reduction process can improve the quality of the coated steels by decreasing the amount of external selective oxidation. This economical process can be made during heating by modifying the air/gas ratio of the direct fire furnace or in the rapid cooling section by air injection. A sensor allows measuring continuously the iron oxide thickness of the oxidized strip.
