Aluminium ingot after ejection from mold Pouring molten gold into a mold at the La Luz Gold Mine in Siuna, Nicaragua, about 1959.. An ingot is a piece of relatively pure material, usually metal, that is cast into a shape suitable for further processing. [1]
A hot top, also known as a feeder head, [5] is a specialized riser, used to help counteract the formation of pipes when casting ingots. It is essentially a live open riser, with a hot ceramic liner instead of just the mold materials. It is inserted into the top of the ingot mould near the end of the pour, and the rest of the metal is then ...
In the era of commercial wrought iron, blooms were slag-riddled iron castings poured in a bloomery before being worked into wrought iron. In the era of commercial steel, blooms are intermediate-stage pieces of steel produced by a first pass of rolling (in a blooming mill) that works the ingots down to a smaller cross-sectional area, but still greater than 36 in 2 (230 cm 2).

The original ingots are usually further processed by other methods (rolling, forging, etc.). More than half of global aluminum production uses the Direct Chill casting process. [1] Direct Chill casting operates by pouring liquid metal continuously into a short mold (7.5–15 cm deep) that is open at the bottom.
Continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. Prior to the introduction of continuous casting in the 1950s, steel was poured into stationary molds to form ingots .

Molten metal before casting Casting iron in a sand mold. In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape.
