Abstract

The invention discloses a molten iron desulfurization stirring device and a molten iron desulfurization method adopting the device. The stirring device comprises a rotary driving system, a stirring head, a stirring rotating shaft, a spray gun, a material conveying pipe and a material bin, wherein one end of the stirring rotating shaft is connected with the driving end of the rotary driving system,the stirring head is coaxially connected to the other end of the stirring rotating shaft, the spray gun is arranged inside the stirring rotating shaft and the stirring head, an outlet of the spray gun is located at the end, far away from the stirring rotating shaft, of the stirring head, an inlet of the spray gun communicates with an outlet of the material conveying pipe, and the inlet of the material conveying pipe communicates with an external air source and the material bin. The molten iron desulfurization stirring device is good in molten iron desulfurization dynamic condition, uniform indesulfurization and good in desulfurization effect when being used for desulfurization.

Description

technical field [0001] The invention belongs to the technical field of molten iron pretreatment, in particular to a molten iron desulfurization stirring device and a desulfurization method thereof. Background technique [0002] With the development of social economy, the demand for steel properties is getting higher and higher, and the sulfur element in steel has a significant impact on the mechanical properties, processing properties, and electromagnetic properties of steel, so the control level of the extremely low value of sulfur element in steel has become a limitation The bottleneck for further improvement of steel performance. In industrial production, hot metal pretreatment desulfurization is the most economical and efficient means, and the most commonly used desulfurization method is the KR stirring method. [0003] However, the traditional KR mixing method is to naturally discharge the material to the top of the molten iron tank through the silo. The natural discha...
