Electric Arc Furnace Process - an overview - ScienceDirect

Boiler slag is the agglomerated residues formed in coal-burning facilities; coal combustion furnaces in thermal power stations, for instance. Boiler slag is formed at the base of the furnaces, mainly slag-tap and cyclone types, at temperatures of 1500–1700 °C (2732–3092 °F). The molten slag is collected and quenched with water-forming
