METHOD FOR PREVENTING SLAG INCLUSION IN CONVERTER STEEL TAPPING

摘要

The present invention relates to a slag leakage prevention method in the process of converter steel tapping for preventing slag leakage when steel is tapped to a ladle after undergoing converter refining. Provided is a slag leakage prevention method in the process of converter steel tapping comprising: a step for maintaining a temperature of a slag in a late converter blowing phase at a preset temperature; a step for putting a slag solidifying agent into the converter before a molten steel is tapped to a ladle after the converter refining is finished while maintaining the slag temperature in the above step; and a step for tapping the molten steel to the ladle by tilting the converter after the slag is solidified by the putted slag solidifying agent.
