Steel foundry. Casting of large parts.

This dossier deals with the means and techniques used to cast very large steel castings. For a better understanding of what is meant by "very large parts" in steel casting, the reader is referred to Dossier "Steel foundry. Casting of large parts".

This dossier also provides a detailed method for determining etching systems based on the refractory pottery usually used to cast solid steel parts. It covers the different type-systems, the main filling conditions (temperatures, speeds, casting modes, degradation of casting materials, etc.), as well as the parameters required for calculations (notions of staggering, whether or not systems are clogged at the time of casting, principle of adjusting ladle flow to cavity filling systems, evaluation of pressure losses, etc.).

It reviews the software tools available to the foundry to help design these systems. Examples of calculations and simulations illustrate the discussion.
