Dual gun device for continuous desulfurization and blowing desulfurization agent of steel plant

Abstract

The invention relates to a dual gun device for a continuous desulfurization and blowing desulfurization agent of a steel plant. The dual gun device comprises a rack, a pair of single gun devices, lifting trolley devices and a transverse movement device. The transverse movement device is divided into a fixed part and a moving part, and the fixed part is fixedly connected with the rack. The pair ofsingle gun devices is fixedly connected with the moving part, a lower guide rail device is fixed to the fixed part, and the moving part can drive the pair of single gun devices to move along the lowerguide rail device. The transverse movement device bears the pair of single gun devices. The single gun devices are provided with lifting guide rails providing guiding for the lifting trolley devices.A top wheel device is arranged on each single gun device, corresponding top rail devices are arranged on the rack, and the top rail devices are located over the top wheel devices. A locating device is fixedly arranged on the rack, and a locating hole corresponding to a transverse locating pin of the locating device is formed in the transverse movement device. According to the dual gun device, thespray gun service life is prolonged, and equipment shutdown and the production halting probability caused by spray gun body failures are reduced; and continuous desulfurization work of a steel makingdesulfurization station is achieved.

Description

technical field [0001] The invention relates to a double-gun device for continuously desulfurizing and blowing desulfurizing agent in a steelmaking plant, belonging to the technical field of steelmaking desulfurization. Background technique [0002] Steelmaking desulfurization reaction is a physical and chemical reaction to remove harmful impurity sulfur in the process of steelmaking and molten steel refining outside the furnace. The production of low-sulfur steel requires serious desulfurization in all links of blast furnace ironmaking, hot metal pretreatment, steelmaking, and molten steel refining. It is also necessary to optimize the desulfurization operation of the entire production process according to the different requirements of the product for sulfur, so as to minimize the desulfurization cost. [0003] Existing desulfurization stations in steel mills generally use submerged spray guns to accurately spray a certain amount of desulfurizer (CaO, Mg, etc.) craft. ...

Problems solved by technology

[0004]However, the current desulfurization spray guns are all single-gun structures. Due to the heavy production load, changing the gun after the pipeline is blocked or changing the normal spray gun life will affect the production rhythm. Continuous desulfurization production operations cannot be realized, and the continuous production of a single gun will reduce the service life to a certain extent
