Glossary

Alloy of iron and carbon obtained by melting pig iron and scrap iron and steel, so brittle and hard that it has to be shaped by casting to produce objects of any desired shape.

In foundry, it is a machine used for pouring molten metal from the pressure furnace or the pouring ladle into the refractory on the molding line.

In foundry, it is a part of the pressurized furnace into which molten metal is raised and along which it flows to the mould.

Accumulation of substance in the flow passage between the tundish and the mould due among others to sticking of metal oxide on the nozzle wall or submerged entry nozzle/submerged entry shroud(SEN or SES).

Machine for pouring liquid metal in a continuous manner from the ladle into the mould where it solidifies and is guided to be cut for further processing. Examples of continuous casters: 4-6 strand continuous billet casting machine/ billet caster form small metal sections of less than 150mm x 150 mm 2- 4 strand bloom caster cast sections of above 150mm x 150 mm Single strand slab caster uses only one strand to produce 150-400 mm thick and 100–1600 mm wide sections

Steel continuous casting is a process consisting of gradual solidification of molten steel into semi-finished shapes such as billets, blooms, H-beams, slabs and thin slabs, without interruption. During the operation, the liquid steel flows from a ladle through a tundish into water cooled copper mold. Then, carried by the roll mills, it freezes and it is cut to desired length.

Upper part of a box on horizontal molding line.

Pieces of copper that constitute the inner wall of a mould in a continuous casting. These copper plates extract heat from the liquid metal going through the mould, with purpose to create a solidification shell (skin). They are cooled by strong water cooling on the external side of the plate.

In pouring process, it is the “entrance door” to the mould.
