Abstract

The invention belongs to the field of ferrous metallurgy, namely the field of external desulphurization treatment to molten iron in a ladle, and particularly relates to an inverse V shaped granular magnesium molten iron desulphurization spray gun. The spray gun comprises a gun body; the gun body comprises a frame (1) matched with a refractory material (2), a passage arranged in the gun body (3), a material flow distributor (4), and a bent pipe (5); a feeding port of the material flow distributor (4) is matched and connected with a discharge port of the passage (3); the discharge port of the material flow distributor (4) is matched and connected with the feeding port of the bent pipe (5); one end of the bent pipe (5) is provided with a nozzle (6); the outside of the nozzle (6) is provided with a refractory bushing (7); the discharge port of the material flow distributor (4) is detachably matched and connected with the feeding port of the bent pipe (5); and the end of the bent pipe (5) is detachably matched and connected with the nozzle (6). The spray gun has high feeding strength and short processing period, can effectively ensure the reliability of pneumatic conveying of a magnesium material, and guarantee the process requirement.

Description

technical field [0001] The invention belongs to the field of ferrous metallurgy, that is, the field of desulfurization treatment of molten iron outside a furnace in a ladle, and in particular relates to a desulfurization spray gun with inverted V-shaped granular magnesium molten iron. Background technique [0002] The known spray gun structure that magnesium is used for the desulfurization of molten iron either has a vaporization chamber at the outlet of the submerged spray gun passage or does not have a vaporization chamber, but powdered magnesium and passivating agents (lime, calcium carbide, dolomite, etc.) are used )mixture. The above-mentioned spray guns have some inherent disadvantages, such as large material consumption, low absorption rate of desulfurization agent, complicated mechanical equipment and spray gun installation and heavy benzene, which result in complicated process and high desulfurization cost. The spray gun with vaporization chamber has successfully s...
