Primary vs Secondary Steelmaking What s the Difference
· What is secondary steelmaking exactly Also known as electric arc furnace steelmaking secondary steelmaking lives up to its namesake by relying on an electric arc to melt scrap iron. After the scrap iron has been melted it s mixed with carbon and converted into steel. With secondary steelmaking a refractory-lined vessel is used as the furnace.
