Method for producing nickel-containing steel by utilizing crude nickel-iron

The invention provides a method for producing nickel-containing steel by utilizing crude nickel-iron. The method comprises the following steps of: arranging a crude nickel-iron hopper on a molten iron trough, and previously adding the crude nickel-iron to the crude nickel-iron hopper; when molten iron starts to enter a molten iron tank from the molten iron trough, and adding the crude nickel-iron by utilizing the crude nickel-iron hopper so that the crude nickel-iron flows into the molten iron tank with the molten iron; preprocessing the molten iron with the crude nickel-iron added; and delivering the preprocessed molten iron into a steel smelting furnace for steel smelting to obtain nickel-containing molten steel. The method for producing the nickel-containing steel by utilizing the crude nickel-iron can increase the production efficiency and reduces the production cost.
