Ingot molds are tapered to prevent the formation of cracks due to uneven cooling. A crack or void formation occurs as the liquid to solid transition has an associated volume change for a constant mass of material. The formation of these ingot defects may render the cast ingot useless and may need to be re-melted, recycled, or discarded.
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).

Supposedly, the iron fish hack helps increase iron intake, but whether or not it is effective depends on a variety of factors, says Leigh A. Frame, PhD, associate director of the George Washington ...
Pig iron, also known as crude iron, is an intermediate good used by the iron industry in the production of steel. It is developed by smelting iron ore in a blast furnace . Pig iron has a high carbon content, typically 3.8–4.7 %, [ 1 ] along with silica and other dross , which makes it brittle and not useful directly as a material except for ...
The best yield of iron achievable from dry puddling is one ton of iron from 1.3 tons of pig iron (a yield of 77%), but the yield from wet puddling was nearly 100%. The production of mild steel in the puddling furnace was achieved circa 1850 [ citation needed ] in Westphalia , Germany and was patented in Great Britain on behalf of Lohage, Bremme ...
The Iron Man is a piece of a poured pig iron ingot. It is approximately 2.18 meters long and about 1 meter of its T-shaped end is in the ground. This was apparently intended as an attachment point for transport and processing and has until now, as an anchoring point, prevented any attempt at removing the ingot by force.
Diets rich in four different types of nutrients may help reduce iron buildup in the brain and lower the risk of cognitive decline that comes with aging, a new study suggests.
Cast iron development lagged in Europe because wrought iron was the desired product and the intermediate step of producing cast iron involved an expensive blast furnace and further refining of pig iron to cast iron, which then required a labor and capital intensive conversion to wrought iron.
