Glossary

In foundry, it is a mass of sand compacted and pushed out by a molding machine against the next lump, both of them forming a mould.

Molded structures resulting from continuous casting such as billets, blooms or slabs that can be subsequently used for further processing ( for example lamination or forging).

In steel continuous casting, it is a process that consists of casting at least two heats in a row in order to reduce yield loss and increase caster productivity.

In continuous casting, it is a machine used to change the hot tube in the tundish without interrupting the casting sequence .

Flat finished product issued from rolling, of rectangular cross section with thickness of no less than 0.15mm and whose width is much greater than its thickness.

Flat-shaped and large continuously cast piece of steel, usually 150-400 mm thick and 1000-3000 mm wide. Rolled into coil, plate and sheet after reheating and used in the automobile industry, food industry (cans) and shipbuilding industry.

Mass of ash gathering on the bottom of the furnace during the metal melting process, containing mostly non-metallic impurities, and intended to be withdrawn.

Channel below the cup used to guide the liquid metal to the mould cavity

Alloy of iron and carbon, subject to forging and laminating during which it becomes hard, strong or malleable.

Process consisting of casting molten steel moulds.

Categorization of steels according to their chemical composition, for example the quantity of carbon, and their physical properties.

Incident resulting from solidified skin’s adhesion to mold faces, which can lead to a breakout. Sticking detection system is used to prevent the breakout by the aid of sensors placed on the mould face.

Device used for moving and controlling the stopper rod position(mechanism). Can be electrical or hydraulic .

Nozzle cleaning produced by a controlled fast vertical oscillation of the stopper.

The ability of the stopper to regulate the flow of molten metal through the nozzle by opening or closing the stopper rod, whether to fill a mould (foundry) or control a level in mould (continuous casting)

Action aiming to remove the slag from the nozzle by closing the stopper in a fast and short manner.

Term applied to a refractory rod placed in the bottom-pour ladle or tundish used to adjust the flow of molten metal through the nozzle into the casting by adjusting the opening space above the nozzle.

Device composed of a rod and a nozzle used for regulation of molten metal as it flows by gravity from one point to the other (ex. from tundish to mould on a continuous casting machine).

Part of the continuous casting machine through which flows the molten metal after it leaves the tundish. There can be only one strand in a slab casting machine whereas billet and bloom casters dispose of 2- 6 of them.

Refractories placed below the tundish to prevent metal re-oxidation of molten steel and guide the flow to the mould.

In continuous casting, it is a one piece refractory tube below the stopper used to prevent metal re-oxidation and guide the flow to the mould.
