Innovation
Key technology for the processing of silicon steel:
- Highest process accuracy and repeatability guarantees stable magnetic properties
- Lower operational costs (electricity); lower investment and maintenance costs
- Top level coating uniformity with high cooling uniformity preventing material tensioning
- High-turbulence high-efficiency Medium Current Density (HTMCD) electrolytic cleaning tank
- High efficiency quick maintenance brushing unit (brush-to-brush type)
- BCO (Brush Consumption Optimization)
- Camber improving special steering rolls at Furnace exit
- Strip cooling sections before MgO slurry coating with multi-channels cooling rolls design for even strip temperature.
- Coater design with upper applicator rolls allowing opening at joint passage avoiding slurry recirculation stop.
- Coater design lower applicator roll provided with hydrodynamic tray to spread uniformly the slurry on the roll face allowing to keep empty the coater drainage pan
- Lower roll with independent servo-actuator on each support for ‘in force’ and ‘in position’ control for top level coating uniformity across width and trouble-free weld joint passage management
- Slurry mixing and preparation system with temperature control and improved mixing and recirculation features, to assure optimal hydration and to avoid slurry aging phenomena, provided with automatic rinsing cycle, self-draining geometry to avoid particles agglomeration
- Special design of drying and exit section with minimum strip to roll contact for better MgO coating quality
- Flying shear in exit section to minimize coating speed transients for improved MgO coating quality constancy
