Abstract
Official abstract text for this publication.
A continuous hot-dip plating machine includes: a sink roll provided in a plating bath and configured to upwardly change a transfer direction of the steel strip; a first support roll provided in the plating bath and located above the sink roll, the first support roll being in contact with a first surface of the steel strip in contact with the sink roll; and a second support roll provided in the plating bath and located above the first support roll, the second support roll being in contact with a second surface of the steel strip opposite the first surface. A diameter of the first support roll, a diameter of the second support roll, and a vertical distance between a rotation axis of the first support roll and a rotation axis of the second support roll satisfy specific conditions.

1 . A continuous hot-dip plating machine comprising: a plating bath; a sink roll provided in the plating bath and configured to upwardly change a transfer direction of a steel strip; a first support roll provided in the plating bath, the first support roll being positioned above the sink roll and in contact with a first surface of the steel strip in contact with the sink roll; and a second support roll provided in the plating bath, the second support roll being positioned above the first support roll and in contact with a second surface of the steel strip opposite the first surface, wherein a diameter of the first support roll, a diameter of the second support roll, and a vertical distance between a rotation axis of the first support roll and a rotation axis of the second support roll satisfy conditions represented by formulae (1) to (4) below, D = D 2 - 0.376 D 1 ( 1 ) 420 - 0.839 L ≤ D ≤ 445 - 0.655 L ( 2 ) D 1 ≥ 210 ( 3 ) D 1 + D 2 ≤ 1000 - 2 L + 2 ( 20 - D 1 2 ) 2 ( 4 ) where: D 1 represents the diameter (mm) of the first support roll, D 2 represents the diameter (mm) of the second support roll, and L represents the vertical distance (mm) between the rotation axis of the first support roll and the rotation axis of the second support roll. 2 . The continuous hot-dip plating machine according to claim 1 , further comprising: an adjuster configured to adjust a vertical position of the first support roll. 3 . A continuous hot-dip plating method comprising: upwardly changing a transfer direction of a steel strip using a sink roll provided in a plating bath; passing the steel strip through between a first support roll and a second support roll, the first support roll being provided in the plating bath at a position above the sink roll and in contact with a first surface of the steel strip in contact with the sink roll, the second support roll being provided in the plating bath at a position above the first support roll and in contact with a second surface of the steel strip opposite the first surface; and adjusting in advance a vertical position of the first support roll so that a diameter of the first support roll, a diameter of the second support roll, and a vertical distance between a rotation axis of the first support roll and a rotation axis of the second support roll satisfy conditions represented by formulae (1) to (4) below, D = D 2 - 0.376 D 1 ( 1 ) 420 - 0.839 L ≤
