Steel production: from iron ore to functional industrial products. Vepica

How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The orebased process uses a blast furnace or smelter and the scrapbased process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.
