A METHOD FOR INCREASING VESSEL LINING LIFE FOR BASIC OXYGEN FURNACES |
摘要 |
A method for increasing the life of the refractory lining of a basic-refractory-lined vessel for the production of steel by blowing oxygen into a ferrous melt from above the surface of the melt, comprising: (a) introducing into the vessel slag forming ingredients, including dolomitic lime, such that the amount of dolomitic lime exceeds the amount normally used, and (b) introducing inert gas into the melt in such manner as to cause intensive interaction between the slag and the melt. The preferred inert gas is argon. |
