ROLLER INTERVAL ADJUSTMENT METHOD OF CONTINUOUS CASTING MACHINE AND CONTINUOUS CASTING METHOD OF STEEL PIECE

Japanese Patent JP2016010803

A

PROBLEM TO BE SOLVED: To provide a roller interval adjustment method of a continuous casting machine and a casting method of a steel piece capable of shortening a time required for adjustment of a roller interval.SOLUTION: A roller interval adjustment method of a continuous casting machine includes: a second roller interval calculation process (S102) of calculating a second roller interval R of a roller segment 4 from a measurement result of a first roller interval r; a reduction gradient calculation process (S104) of calculating a reduction gradient G from the second roller interval R of adjacent two roller segments 4; a first roller interval increment/decrement amount calculation process (S110) of calculating a roller interval increment/decrement amount of the roller segment 4 on which the second roller interval R of the adjacent two roller segments 4 exceeds a first standard when the reduction gradient G is less than a standard reduction gradient; and a roller interval adjustment process (S112) which increases and decreases the first roller interval r in accordance with the roller interval increment/decrement amount.
