Steel manufacture

An important feature of iron making is that the process is continuous. When a sufficient quantity of molten iron accumulates in the hearth of the blast furnace, it is tapped off into ladles for steel-making. As slag builds up on the surface of the molten metal it, too, is tapped off at regular intervals through a separate ''notch'' or taphole.
