AI Technical Summary
The existing narrow-edge copper plate plating structure of ultra-thin slab crystallizers has a short service life, leading to frequent replacements, which affects the production stability of continuous casting machines and the service life of the equipment.
A strip-shaped wear-resistant coating is set on both sides of the second working surface of the narrow-edge copper plate in the ultra-thin slab crystallizer. Combined with cobalt-nickel alloy or nickel-cobalt alloy materials, it improves wear resistance and retains heat transfer capacity, and avoids the copper plate side being scratched.
It extends the service life of copper plates, reduces the frequency of equipment maintenance, improves the operating rate and production stability of continuous casting machines, and reduces maintenance costs.
