Abstract
A rolling mill in which the size of a rolling material at the outgoing side of rolls and the reaction force from the material exerted to the rolls are successively obtained from respective sampling periods to be used as data for calculating the most reliable mill modulus of the mill and an offset value of the roll gap by an arithmetic operation, which are fed to a rolling control system for controlling the rolls.
Claims9
A rolling mill for rolling an elongated transferring material continuously through at least a pair of rolls opposed to each other with a gap forming therebetween, said rolling mill including:
- a plurality of measuring means for measuring data, including size of the material, the gap between the rolls, and the reaction force exerted on the rolls, associated with said rolls;
- and
- arithmetic processing means connected to said measuring means for receiving and utilizing said data during a plurality of successive sampling periods from said measuring means to execute a predetermined arithmetic processing to separately calculate the most reliable values of a mill modulus which said rolling mill possesses and an offset of said gap, and providing the values as input data for controlling said rolls, said arithmetic processing means being provided for each of said pair of rolls.
