Creating Steel HowStuffWorks

Creating Steel Howstuffworks

The open-hearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an open-hearth furnace. It is heated to about 1,600 degrees F 871 degrees C. The limestone and ore form a slag that floats on the surface. Impurities, including carbon, are oxidized and float out of the iron into the slag.

New technology for the recovery of chromium from EAF

New Technology For The Recovery Of Chromium From Eaf

During the production of stainless steel in an electric arc furnace a significant part of the charged chromium is transferred to the slag. With the new technology of aluminium injection, chromium is recovered from the slag, thus alloying components and costs are saved. Typical mechanically processed Al granules used for the EAF slag injection grain size approx. 1ampndash2 mm are displayed.
