Abstract

An apparatus (100) for continuous monitoring of a metallic material (20) in a rolling process, comprising: at least one roll- separating force sensor (101); at least one strain sensor (102); at least one temperature sensor (103); at least one work hardening calculation module (104) which receives as input: roll- separating force applied by one pair of rolls (11, 12) onto the metallic material (20), strain to which the metallic material (20) is subjected, an equivalent radius size associated to radius of a working roll (11), a thickness of the metallic material (20), a contact angle between the working roll (11) and the metallic material (20), an effective friction coefficient between the metallic material (20) and the pair of rolls (11, 12). A related method for continuous monitoring of a metallic material (20) in a rolling process.
