TWIN ROLL CONTINUOUS STRIP CASTER (ST TYPE)
ST type continuous casters have 660 mm diameter rolls with split out gearbox and single drive motor. These types of casters have proved their reliability through the years and still perform well by means of power consumption and operation easiness. They have low initial investment costs because of smaller diameter rolls and post sizes. They have same disadvantages such as having slow casting in comparison with SP type and working on limited strip width.

VIG-S Caster Properties
• Caster roll diameter range: 600 – 660 mm
• Maximum strip width: 1650 mm
• Strip thickness range: minimum 5 mm, maximum 10 mm.
• Casting speed range: 0,8 - 1,35 meter/minute (acc. to alloy)
• Aluminium alloys: 1XXX, 3003, 3005, 5005, 8011 series.
• Hydraulic gap control is available
• Edge milling is available

TWIN ROLL CONTINUOUS STRIP CASTER (SP TYPE)
SP type continuous casters have higher roll diameters starting from 850 mm; mostly supplied at 1010 mm. VIG Makina manufactures Twin Roll Casters with up to 1120 mm diameter rolls. These types of casters are distinguished by the bigger caster rolls which are driven by planetary gearboxes and two separate motors. It is argued by many authorities that the strip quality of SP type Twin Roll Caster is better from the strip quality of the ST type Twin Roll Caster because of the increase in hot rolling in the casting process.

VIG-C Caster Properties

Twin Roll Continuous Strip Caster Equipments
• Motorized Tip Table: Positioning of tip is maintained during the casting operation, allowing flexible operation.
• Twin Roll Continuous Strip Caster Rolls: Caster cores are specially treated to lower the corrosion and deformation in the grooves. After the shell and core are combined via shrink fitting; turning and grinding operations are performed on the caster rolls.
• Graphite Spraying System: Fully automated spraying system can be offered upon request.
• Pinch-roll, Flying Shear, Winder and Coil car units are supplied with the caster line properties.
• Edge Milling is offered to provide smooth edges of the strip which would reduce the edge trimming operation in other processes.
