A ladle of steel is teemed (or poured) through, a gas tight refractory tube, into a tundish. The tundish is a reservoir that allows the steel to flow at a controlled rate through further gas tight refractory tubes and into a series of water-cooled copper moulds. With only the outer shell solidified, the steel is drawn from the bottom of the mould through a curved arrangement of support rolls and water sprays.It emerges horizontally in the form of a solid steel strand. At this point it is cut to length using automatic gas burners.
