Document Type and Number:
Japanese Patent JP6601363
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for application of a pressure roll, a pressure roll, a steel plate rolling method, and a steel plate manufacturing method.SOLUTION: A pressure roll 1 has a first clutch 1c at one end and a second clutch 1d at the other end, an outer diameter of the second clutch is so formed as to be larger than an outer diameter of the first clutch, a coupling 2 is inserted in the first clutch, and a rolling machine is operated until the first clutch and the coupling reach a preset abrasion loss. The pressure roll is removed from the coupling and is reversed, the second clutch is inserted in the coupling, and the rolling machine is operated until the second clutch and the coupling reach a preset abrasion loss. After the coupling is repaired, the first clutch is inserted in the coupling, and the rolling machine is operated until the first clutch and the coupling reach a preset abrasion loss. The second clutch is inserted in the coupling, and the rolling machine is operated until the second clutch and the coupling reach a preset abrasion loss.SELECTED DRAWING: Figure 3
