Abstract
Slag coating is accomplished by blowing a gas from a top-blown lance such that slag is splashed uniformly onto the barrel and throat near the trunnion of the converter; the lance height is adjusted to 0.7-3.0 m and the gas flow rate is adjusted to 250-600 Nm /min and, after gas blowing, the remaining molten slag is incorporated with a slag solidifier containing MgO or CaO and the molten slag is splashed toward the desired part of the converter wall that needs repair.
