Slag Cement Lehigh Hanson, Inc.

Slag cement, originally known as granulated blast-furnace slag, begins with the production of iron. The heart of the process is the blast furnace that refines iron ore into iron. The ingredients are heated to nearly 1500 degrees Centigrade to form two components: iron and molten slag.

Sand For Concrete From Steel Mills Induction Furnace Waste

ELECTRIC FURNACE 1. Electric Arc Furnace The heat in the arc furnace is generated by an electric arc between two or more electrodes which are usually graphite or carbon between the electrodes and furnace charge or between two or more electrodes. When the scrap is melted down completely and melted slag has come over the top, the slag is tapped off completely by tilting the furnace.
