In the process of making steel, impurities such as oxygen and sulfur are removed. Alternatively, it is added to improve the strength, toughness, heat resistance, corrosion resistance, etc. of iron. Indispensable in this process is something called “ferroalloy,” which is artificially created by combining iron and specific metals, and our important role is to provide a stable supply of this material to steel manufacturing companies.

Primary steelmaking involves smelting iron into steel. Secondary steelmaking involves adding or removing other elements such as alloying agents and dissolved gases. Tertiary steelmaking involves casting into sheets, rolls or other forms. Multiple techniques are available for each step.

A typical steel mill uses an electric furnace to produce one ton of steel, using approximately 400 to 450 kilowatt hours of energy.
