Problems solved by technology

[0002] Existing hot metal desulfurization spray guns have disadvantages such as high material consumption, low utilization rate of desulfurization agent, bulky spray gun body, and high desulfurization cost.
Due to the above shortcomings, desulfurization outside the furnace cannot be carried out smoothly, especially in large (equal to or greater than 160t) ladles, the structural defects are more obvious

Embodiment Construction

[0018] The present invention comprises: a pipe 1, a gun body 2, a refractory layer 4 located outside the gun body 2, a skeleton 3 attached to the outside of the gun body 2 and placed in the refractory layer; the pipe 1 can be fixedly assembled on the gun body 2 Inside, the pipeline 1 can also be assembled in the gun body 2 in a detachable manner. A refractory sleeve 5 is provided at the outlet end of the pipeline 1 . The outlet end of the pipeline 1 is a bell mouth structure. The pipe 1 is placed in the gun body 2 and kept at a certain distance from the inner wall of the gun body 2 . The inner diameter of the pipeline 1 is equal to or greater than 10 times the diameter of the magnesium particles, and its length is not less than 420 times the inner diameter of the pipeline 1 .

[0019] The pipeline 1 of the present invention is used to transport magnesium, and the frame 3 and the gun body 2 are all made of steel. The refractory casing 5 can prevent the pipe of the pipeline 1...

Description

technical field [0001] The invention belongs to the category of molten iron desulfurization treatment devices, in particular to a molten iron desulfurization spray gun. Background technique [0002] The existing molten iron desulfurization spray guns all have the disadvantages of high material consumption, low utilization rate of desulfurization agent, bulky spray gun body, and high desulfurization cost. Due to the above-mentioned shortcomings, desulfurization outside the furnace cannot be carried out smoothly, especially in large (equal to or greater than 160t) ladles, the structural defects are more obvious. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a molten iron desulfurization spray gun with simple structure, high utilization rate of desulfurizer, low operating cost and good desulfurization effect. [0004] Technical solution of the present invention can be realized in the following manner: [0005] A...
