Casting Roll for Twin-Roll Strip Caster

This patent describes a casting roll and a method for manufacturing high-nitrogen duplex stainless steel strip without dimples. The roll has an average surface roughness of 10 to 30 micrometers and diagonal fine grooves with specified widths, intervals, and depths. The grooves intersect symmetrically at angles of 30 to 70 degrees relative to the roll’s circumferential direction.

Apparatus for Preventing Damage to Casting Rolls in Strip Casting Machine

This patent describes an apparatus that detects the pressing force applied to casting rolls and uses that measurement to determine whether foreign objects have entered the rolls. If foreign objects are detected, the apparatus adjusts the roll-gap instruction value by adding a preset amount to the set gap. This control approach is intended to reduce damage to the roll surfaces.
