Nothing short of revolutionary, our Belt Casting Technology (BCT®) is a further leap toward near-net-shape casting. Depending on the BCT® caster type you choose, you can run different production rates and manufacture a large variety of product sizes. What makes BCT® casters so special is that they handle alloys previously not suitable for continuous casting. Furthermore, the new technology also copes with crack-critical conventional steel grades impossible to produce by standard continuous casting.
Concepts
Batch and inline production
Major highlights
- New high-strength, high-ductility steel grades for the automotive industry
- Horizontal casting: no bending or straightening
- Moving mold: no casting powder
- Casting process for special grades and small
- production volumes
Technology
New steel products need new casting processes
Forget bending or straighteningProtected from reoxidation, the liquid steel is poured from a conventional ladle into a covered tundish. Then it goes through a submerged entry nozzle into the preheated feeding system. Next, the steel flows onto the moving horizontal mold consisting of the conveyor belt and internally cooled side dams. There is an inert gas atmosphere above the conveyor belt to protect the solidifying steel. Finally, at the rear end of the caster, a defined gas mix directly influences the solidification structure.
Impressive features
Stress-free strip solidification in horizontal direction:
No bending or straightening
Casting without powder:
Steels with high aluminum content possible
Traveling mold, no oscillation:
Plane strip surface without oscillation marks
Rapid solidification, high casting speed, low casting thickness:
Fine-grain cast structure without risk of segregation
Inert atmosphere and exclusively indirect cooling:
No scale formation during the casting process
Sufficient deformation at strip gauges of 8-20 mm:
High-quality hot strip
BCT®: Process and main characteristics
As-cast stripThe as-cast strip leaves the conveyor belt horizontally. Then it enters an enclosed roller table which ensures complete process inertization right up to the end of the table. Next in line after the roller table is a combination of two pinch-roll stands separated by a looper. This section not only transports the as-cast strip, it also isolates the product from downstream influences. The second pinch roll unit feeds the strip to a moving hydraulic shear. To ensure the required sheet lengths, the shear travels at the same speed as the as-cast strip. Now a roller table accelerates the up to 9-m-long sheets toward the end of the roller table, where they slow down again. Finally, cross-pushers place the sheets on a hydraulic lifting table.
Benefits
Casters customized to your requirements
New steel products demand new casting processes- Lightweight design und safety based on high energy absorption
- Customized product properties
- New engineering and design options for components
Extremely versatile, these casters combine with both BOF and electric-arc-furnace melt shops. What's more, we tailor your BCT® installation to your particular needs. You can produce medium-wide strip just as well as hot wide strip. Whether you have small, medium, or high production capacities, we design your plant to suit you.
Your benefits
- Tailor-made, compact plant design for implementation in all common process routes
- Cutting-edge casting for integration in state-of-the-art thin strip facilities
- Unique technology for a wide range of high-performance new steels as well as critical conventional grades
- No breakouts
- Lower maintenance compared to conventional continuous casters (e. g. mold and segment shop)
- No water consumption (closed circuit)
- Tomorrow's technology today
