slab caster rolls roller rollers are the most imoprtant spart parts in the production of continuous casting, the working life of CCM rollers directly effect the production efficiency and production cost. Under the normal production, the temperature of casted strip will be 1100℃-1200℃ and speed of casted strip will be 0.3-1.2 m/min. The area temperature of rollers which touch strip change from 300℃ to 600℃ for turning a circle. So the working condition of CCM rollers under high temperature and moist environment.
Following is material that used on slab caster rolls
