The Making of Iron Steel SEAISI

major steelmaking method involves the melting and refining of steel scrap in an Electric Arc Furnace. Pig iron and refined iron ore pellets (briquetted iron) can also be used, and because his t method is economic at lower volumes these operations are called mini mills. Plants that use Electric Arc Furnaces can be sited closer to the market.
