Bloom sections are required in cases where final steel products of the highest purity and flawless internal quality are to be produced for high-end applications. The same applies to particularly large end products.

In order to achieve the required purity and internal quality, SMS Concast continuous bloom casters have some striking features, such as the tundish heating systems, integrated molds (including INVEX^® mold technology), an electromagnetic stirrer system (CONSTIR), innovative strand support design, including dynamic mechanical soft reduction (DMSR), and controlled surface quenching. DMSR is necessity in order to achieve a sound bloom center and minimized center segregation. In addition to the mechanical components, SMS Concast also supplies the metallurgical models, such as the COOL solidification model.

Blooms can be as well cast on vertical casting machines and may very well replace ingot casting machines.
