Recent Improvement of the Caster Strand Monitoring Technology of POSCO for Flow Path Management of Continuous Casting Machine

摘要

A significant improvement has been achieved in strand maintenance technologies for continuous casting machines at POSCO by using the advanced type Caster Strand Monitoring System (CSMs) designed to measure the roll gap, roll bending, roll alignment, roll rotation and the strength of water/mist spray for slab cooling. Through comprehensive test and comparisons, it is concluded that the upgraded CSMS is a very useful tool to accurately determine the condition of strand in a slab caster. The plant operator can obtain comprehensive information about strand condition for high quality continuous casting and reliable plant maintenance.
