Double Poured Indefinite Chilled Cast Iron Roll(ICDP)
Features
Indefinite chill cast iron is a material between chill cast iron and grey cast iron. The work layer of this material consists of flakes 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, banite, martensite or tempered sorbite through adjusting the chemical composition. The rolls of this material possess excellent wear-resistance, thermal cracking resistance, spall resistance and biting properties.
