Abstract

The invention relates to an immersion type desulfurization device with mechanical stirring. The desulfurization device comprises an immersion type spray gun and a mechanical stirrer. The immersion type spray gun is inserted into the hollow part of the center of the mechanical stirrer. The immersion type spray gun comprises a spray gun flange connector and a spray gun body that is connected to thespray gun flange connector. The center of the spray gun flange connector is provided with a powder inlet. The center of the spray gun cavity is a hollow cavity. The lower end of the spray gun cavity is provided with a spraying agent outlet. The spray gun flange connector is used to connect a material conveying facility. The mechanical stirrer comprises a stirrer flange connector, a stirring shaft,and a stirring blade. The stirrer flange connector is fixedly connected to the stirring shaft. The lower end of the stirring shaft is fixedly connected to the stirring blade. The stirrer flange connector is used to connect a stirring facility. The provided device can guarantee that in immersion type blowing, materials in a molten pool are fully and evenly stirred and mixed, the powder dispersionand stay time is increased, the dynamic conditions of desulfurization process are greatly optimized, the manufacturing cost of the device is low, and an ideal desulfurization effect is achieved.

Description

technical field [0001] The invention relates to a submerged desulfurization device with mechanical stirring, belonging to the technical field of molten iron pretreatment. Background technique [0002] Sulfur is one of the main harmful elements in iron and steel products (except sulfur-containing steel). As the main raw material for molten steel smelting, molten iron affects the quality of steel to a certain extent. With the continuous improvement of the market's requirements for steel quality, the requirements for high strength, low temperature toughness, cold formability and welding performance of steel are becoming more and more stringent. In order to meet this requirement of the market, iron and steel industries all over the world are working hard to improve the quality of steel by reducing sulfur in steel. [0003] At present, the desulfurization of molten iron mainly adopts mechanical stirring method and powder spraying method. Among them, the mechanical stirring metho...
