| description | The invention discloses a method for vulcanizing ferronickel, which comprises the following steps: smelting ferronickel in an ore-smelting electric furnace, enabling the generated ferronickel to automatically flow into a ladle, entering a vulcanizing process, slowly inserting a rotating stirring device into the molten iron, adding a vulcanizing agent into the ferronickel through the stirring device after the rotating stirring device is inserted to a certain depth, and vulcanizing the ferronickel under the action of strong stirring. And sulfur is fully mixed with the molten nickel iron and reacts with nickel, cobalt and iron in the molten nickel iron to generate nickel-sulfur and nickel-cobalt-iron alloy. The method provided by the invention strengthens the mixed reaction of molten ferronickel and sulfur, the curing rate of nickel and cobalt reaches 95% or above, the utilization rate of sulfur is greater than 90%, the content of sulfur dioxide in flue gas is reduced, and the method is environment-friendly, ada |
