Investigation on Steelmaking with Hot Metal Containing Low Silicon Content in Large Converter

Keywords： hot metal

There are some problems in steelmaking with hot metal containing low silicon content such as difficulty in slag formation, less slag for dephosphorization and slag adhesion on oxygen lance and hood. To overcome these problems, experiments were conducted and some improvements were obtained, such as adding appropriate flux,increasing the lance position slightly during steelmaking and using effective multi-outlet nozzle. Moreover, to keep normal heating rate, the ore and scrap charge should be reduced due to less chemical heat input in steelmaking.
