How to make ferronickel?

Ferronickel is an alloy of iron and nickel that is widely used in the production of stainless steel. It's produced through a smelting process that involves the reduction of nickel oxide and iron oxide in the presence of a reducing agent.

One of the most popular methods of producing ferronickel is through the use of DC submerged arc furnaces. These furnaces are particularly efficient in the smelting of nickel ores, as they allow for precise control over the temperature, voltage, and current. Here's a step-by-step guide on how to make ferronickel using DC submerged arc furnace 100~20000kVA from YOUNENGDE:

Preheat the furnace: Start by preheating the furnace to the desired temperature using a preheater. This typically takes several hours.

Charge the furnace: Once the furnace is heated up, add the nickel ore, iron ore, and coke into the furnace in the right proportions. The nickel oxide and iron oxide react with the reducing agents in the coke, producing ferronickel and slag.

Apply power: Turn on the electrical power to start the smelting process. The DC power creates a submerged arc that melts the materials, allowing them to react and separate into their metallic components.

Tap the slag: Once the smelting process is complete, tap off the slag, or the waste material that forms on top of the molten metal. The slag is usually composed of impurities and is less dense than the ferronickel.

Cast the ferronickel: After tapping off the slag, the molten ferronickel is ready to be cast. Pour the molten metal into the desired molds or castings, allowing it to cool and solidify.
