• Testing the material in a blast furnace

• Basic Oxygen Steelmaking 70% iron and 30% recycled steel are mixed with other alloys in the 300 tonne basic oxygen steelmaking furnace to create the metallurgical qualities which suit the customers' end use requirements. The molten metal is then shipped to Dofasco's Ladle Metallurgy Facility. • The KOBM Stream uses primarily iron ore, coal, and limestone as feed materials; as contrasted to the EAF Stream produces steel mostly from recycled scrap.

Electric Arc Furnace • Electric Arc Furnace (EAF) Steelmaking The Electric Arc Furnace uses from 70 to 100% recycled steel as its raw material (as contrasted to the Basic oxygen stream which uses primarily iron ore, coal, and limestone). Dofasco has the flexibility to add molten iron to increase quality or as a substitute, when availability of recycled steel is low

Layout of a steel production plant • Can you see the men in the white coats? • Compare them to the size of the machines.

Steel rolled • The material is rolled at around 900 degrees • This is known as hot rolling.

Steel being rolled • The diagram shows the amount rollers used to roll the steel
