Abstract

In this paper, A test furnace design for use in oxygen-enriched combustion to investigate the oxide scale of steel slab. The heating time, oxygen content and temperature were investigated, and the structure of oxides formed on the slab was characterized. The results show that magnetite film formed on the slab increases in thickness with oxygen enrichment which restricts the diffusion of oxygen and make oxide scale decreased, the oxidation loss of billet has reduced by approximately 37% and the fuel has a 26% fuel savings because of the heating time is decreased
