Bath smelting side-blowing jet flow gush type enhanced stirring method

The invention relates to a bath smelting side-blowing jet flow gush type enhanced stirring method, belonging to the technical field of metallurgy. Firstly a nozzle is inclined to the bottom of a hearth with an inclination angle of 5 to 40 degrees; by reducing the diameter of the nozzle 1 to 1.0 to 3.0cm, and setting wind pressure in an air flue communicated with the nozzle to 0.2 to 0.4MPa, and enabling oxygen-rich air to blow into a bath from the side in a jet flow way, thus generating bath stirring like gush. The body of a side-blowing furnace can be enlarged to increase an effective smelting area, thus further improving smelting intensity of the side-blowing furnace, generating a scale effect, and reducing the unit production cost of the side-blowing furnace. 本发明涉及种熔池熔炼侧吹射流泉涌式强化搅拌方法，属于冶金技术领域。首先将喷嘴向炉膛底部倾斜呈5～40°（即倾斜角度为5～40°），通过缩小喷嘴1直径为1.0～3.0cm，喷嘴连接接通的风道中风压为0.2～0.4MPa，使富氧空气以射流的方式从侧面鼓入熔池内，从而产生像泉涌样的熔池搅拌。本方法能够实现侧吹炉炉体大型化，增大有效熔炼面积，进而提高侧吹炉的熔炼强度，产生规模效应，降低侧吹炉的单位生产成本。
