OVERVIEW
FC MEMS is ABB’s compact mold‑stirring solution for low‑ to medium‑speed thick slab casting. Its two wide‑side stirrers improve mold flow control and thermal consistency, reducing surface and subsurface inclusions, supporting more uniform shell growth, minimizing casting disturbances, and helping increase casting speed, reinforced by ABB’s experience across more than 140 slab mold flow‑control installations worldwide.
Improved slab surface and subsurface quality
<p>FC MEMS helps wash away inclusions and gas bubbles near the surface, supporting cleaner slabs with fewer surface and subsurface imperfections.</p>More uniform temperature distribution and shell growth
<p>Higher and more even temperatures around the SEN support consistent solidification and help reduce the formation of mid‑face longitudinal cracks.</p>Reduced subsurface inclusion entrapment
<p>Improved thermal conditions at the solidification front decrease hook depth, lowering the likelihood of inclusions becoming trapped beneath the surface.</p>More stable and predictable casting behaviour
<p>FC MEMS contributes to steadier operation with fewer disturbances such as sticker alarms, helping maintain reliable casting conditions.</p>More consistent molten powder behaviour
<p>A more uniform temperature field promotes a smoother molten powder layer, supporting stable lubrication and reducing surface irregularities.</p>Potential for higher casting speed and productivity
<p>With improved flow stability and reduced quality‑related limitations, FC MEMS can enable higher casting speeds and support increased output.</p>FEATURES
Delivers targeted influence on mold‑zone flow conditions for thick slab casting.
Purpose‑designed for the casting conditions of thick slab casters.
Installed at the mold to act directly on the flow, eliminating the need for additional devices.
Both stirrers operate in series from a single frequency converter, reducing system complexity.
Can be integrated into the water jacket or mounted externally using manipulators for easier mold exchange.
Designed with long pole pitch and ABB’s dry‑insulated coil technology to minimize power demand and maintenance needs.
Built on ABB’s established EMS coil construction and standardized converter systems for reliable long‑term operation.
FC MEMS can act as an entry‑level solution that complements future upgrades to broader flow‑control capabilities.
ABB metallurgists provide application guidance on mold‑zone flow, process behaviour and tuning.
With more than 80 years of EMS experience, ABB supports commissioning, tuning, maintenance and lifecycle optimization across installations worldwide.
