Product Description
Indefinite chill cast iron is a material between chill cast iron and grey cast iron. The work layer of this material consists of flake graphites, while the depth below barrel surface increases, the amount of graphites will increase too, but the hardness will decrease. According to different rolling conditions, the matrix of the rolls could be controlled as pearlite, bainite, martensite or tempered sorbite through adjusting the chemical composition. The rolls of this material possess excellent wear resistance, thermal cracking resistance, spalling resistance and biting properties.
ICDP rolls are primarily used in the section, wire, rod, strip mills, and the rolls of ICIV, ICV could be used in the hot strip, intermediate - plate an tempered mills.

Advantage
When wear resistance can be markedly improved, users can also benefit from a dramatically improved roll consumption rate. It can also significantly extend intervals between roll replacements.
Excellent wear resistance at high temperatures stabilizes the roll profile, which contributes to improvement of product yield and product surface quality.
Because surface roughening from repeated thermal fatigue is controlled, you can make attractive products rolled by rolls with uniform microstructures.
We can design and manufacture rolls that are ideal for your service conditions and impose minimal stress on the equipment.
