  • Solidification control in continuous casting of steel

    Solidification in continuous casting (CC) technology is initiated in a water-cooled open-ended copper mould. The steel shell which forms in the mould contains a core of liquid steel which gradually solidifies as the strand moves through the caster guided by a large number of roll pairs. The solidification process initiated at meniscus level in

  • Steel - Casting of steel | Britannica

    Casting of steel Ingot pouring. The simplest way to solidify liquid steel is to pour it into heavy, thick-walled iron ingot molds, which stand on stout iron plates called stools.. Solidification processes. During and after pouring, the walls and bottom of the mold extract heat from the melt, and a solid shell forms, growing approximately with the square root of time multiplied by a constant.

  • Review of Peritectic Solidification Mechanisms and Effects ...

    As casting of peritectic steels is difficult, it is important to identify a peritectic steel from its composition. If a new grade of steel is predicted to be a peritectic, then appropriate actions can be taken at the caster, such as applying appropriate mold powders with high solidification temperature to lower the surface cooling rate,[36,37,38] and/or casting at a lower speed.[]

On the solidification of alloys (liquid steel), solute is partitioned between the solid and liquid to either enrich ...

  • Solidification Time of a Casting • Bernier Metals

    During the early stages of solidification of a casting, a thin skin begins to form at the relatively cool mold walls and as time passes, the thickness of the skin increases (as shown in figure 2).For flat mold walls, thickness is proportional to the square root of the solidification time. Thus, doubling the solidification time will make the skin 2 1/2 = 1.414 times or 41% thicker.
