Ladle Shroud for Continuous Casting Manufacturers

A ladle shroud is a crucial component in the process of steelmaking, specifically in the continuous casting of molten steel. It is a refractory-lined tube-like structure that surrounds the outlet of the ladle, which holds the molten steel. The ladle shroud serves multiple purposes within this context.

Firstly, it helps to guide the flow of molten steel from the ladle to the tundish, a holding vessel that feeds the continuous casting mold. This controlled flow is essential to prevent turbulence and minimize the potential for reoxidation or inclusions, which could degrade the quality of the final steel product.

Ladle shrouds are made from refractory materials that can withstand extreme temperatures and chemical reactions with molten steel. Common refractory materials include alumina, magnesia, zirconia, and graphite.

A coating material, often containing a binder and refractory aggregates, is applied to the inner surface of the mold. This coating provides a smooth surface finish and helps prevent the adhesion of the refractory lining to the mold during the forming process.

The refractory material is then installed in the coated mold. It can be in the form of a pre-formed lining or as a refractory mix that is poured, gunned, or rammed into the mold. The refractory lining is carefully shaped to match the desired ladle shroud design.
