Continuous / Ingot Casting

Continuous Casting

Quality control in manufacturing process / Control of nonmetallic inclusions and segregation

A combined electromagnetic stirring system in the mold and terminal stage of solidification is used in continuous casting to reduce inclusions and improve center segregation.

Control of surface defect

The continuous casting process involves automation using computers, leading to the reduction of surface defect by in-mold surface level control with eddy current sensors and uniform cooling in a slab by misting.
