Study on Carbon Monoxide Corrosion on Gunned Layer of Blast Furnace

摘要

The blast furnace dissection has proved the distinct carbon monoxide corrosion to the refractory. This paper describes the situation and the effect factors of the carbon monoxide corrosion on the gunning layer for BF. The results of the study showes that the corrosion of gunned layer depends mainly upon its Fe_2O-3 content, at the same time it also depends on its physical and chemical properties.
