Cast Iron Chill Rolls

Cast iron chilled rolls are heavy industrial rollers featuring a hard, wear-resistant white iron outer shell and a tough, shock-resistant grey or nodular iron inner core. They are produced by rapidly cooling the molten metal surface against a metal mold and are widely used in metal, paper, and rubber rolling mills.

Industrial Applications

Steel and Metal Mills: Hot and cold rolling of steel, copper, and aluminum sheets, bars, and wire rods.

Processing Industries: Crushing, milling, and finishing operations in paper, rubber, and textile manufacturing.

Key Characteristics

Hardness: Surface hardness typically ranges from 40 to 80 Shore C (HSD).

Structure: Features a clear or gradual transition from a carbide-rich outer working face to a softer, fibrous inner core.

Durability: Provides high resistance to wear, abrasion, and thermal cracking.

Main Types

Definite Chilled Rolls: Possess a distinct white iron chill layer over a grey iron core.

Indefinite Chilled Rolls : Contain finely distributed graphite flakes in the working face for better thermal shock resistance.

Double Poured Chilled Rolls: Manufactured via dual-pouring technology to optimize shell depth and core strength.
