Production Practice of Rapid Decarbonization of SPA-H Steel by Converter
It was concluded that there was suitable conditions for the SPA-H steel to be rapidly decarbonized according to its chemical characteristics based on the theoretical analysis.And therefore,after taking such measures as optimizing the oxygen flow and oxygen pressure,re-ducing the average height of lance positions,improving the slagging system and optimizing the bot-tom blowing system,the average smelting time for the SPA-H steel was shortened by 0.6 min and the operation efficiency of a converter was improved.
