Background

The converter steelmaking is a smelting method in which molten iron and scrap steel are used as raw materials, a flux (active lime, light-burned dolomite, fluorite and the like) and an iron alloy are added, and oxygen is blown into a converter to react. In the smelting process of the converter, the oxygen lance enters the converter for oxygen blowing smelting, and steel or slag inevitably overflows and splashes from a furnace mouth in the blowing process due to violent smelting reaction. Usually, a steel plate with a certain angle is arranged on the inner side of the converter foundation retaining wall, and the steel plate is fixedly supported by a steel structure bracket. The flying track of the scattered slag splashed in the converter blowing process is changed when the scattered slag falls down along the steel plate, and the scattered slag enters a slag pit below the converter along the direction of the steel plate.
