1. Formation of iron oxide scale The Iron oxide scale is a metal oxide attached to the surface formed when a billet is processed in a heated or hot rolled state. This layer of oxide may be a dense ferric oxide or loose ferrous oxide. The iron oxide scale is about 5-15 microns thick, the […]

The Basics of Bright Annealing

Bright Annealed Strip Bright annealing, commonly known as bright annealing, is mainly used for heating and annealing in a closed space, allowing the temperature to slowly cool down at least 500 degrees in a closed space, and then naturally cooling, so that there will be brightness without causing decarburization. Oxidation and decarburization occur during heating […]
