Because this slag is less dense than molten metal, it floats on top of the metal and can be removed – it then goes on to be used in the cement and road building industries. The molten metal is 'tapped' from the bottom of the furnace into torpedoes, each one able to carry 300 tonnes of liquid iron, and moved by rail to the steel plant for ...
