Abstract
The chemical corrosion (static wearing condition ) and the mechamo-chemical corrosion (dynamic wearing condition) on magnesia-carbon refracrories were investigated by a high capacity induction furnace. In comparison with respective experiments, the specimens after dynamic wearing had large wearing rates and showed specific corrosion mechanism on microscopic observation. The corrosion resistance of specimen was determined by base material of refractories under static wearing condition. Through dynamic wearing condition, it was possible to mention that the corrosion resistance has influenced by both factors as base matetial and hot modulus of rupture.
