EAF EMS – ELECTROMAGNETIC STIRRER FOR ELECTRIC ARC FURNACE

Quicker stable arc in each bucket, higher average power, decreased electrode consumption. SLAG CHEMISTRY Electromagnetic stirring reduces the oxidation of Fe and Mn under the oxygen lance and improves the reduction of the slag. Lower and more consistent temperature of slag improves slag foaming Ò less FeO and MnO in slag, improved yield.

EAFS is produced in an Electric Arc Furnace. The slag is dark grey in colour and is characteristically harder than blast furnace slag (BFS). It has a density about 20 - 25% greater than basalt or BFS. It crushes to a cubical shape. EAFS in common with most steel slags, is subject to slight dimensional expansion until it fully hydrates.
