thyssenkrupp Explores Greater Scrap Use in Blast Furnaces
In a statement, thyssenkrupp said the process, created by TSR Recycling & Co. KG, allows for targeted separation of consumer scrap, creating a raw material input with clearly defined properties and high iron content. By using high iron-containing inputs, the hope is to reduce the amount of reducing agents needed in the blast furnace.
