    摘要: [Object] To provide a liquid removal device capable of removing liquid on a steel sheet without using wringer rolls and a drier.
    [Solution] A liquid removal device that removes liquid attached to a surface of a sheet-like member that moves relatively, the liquid removal device including: a slit nozzle that jets gas to the surface of the sheet-like member; and a gap measurement device that measures a gap between a jetting port of the slit nozzle and the sheet-like member. The slit nozzle is installed so as to jet gas from a downstream side toward an upstream side in a movement direction of the sheet-like member that moves relatively to the slit nozzle, and is configured in a manner that a jet angle θ, a back face inclination angle β, a back face length L of a nozzle back face, a gap h, a slit width d, and nozzle pressure P n of the slit nozzle satisfy the following relational formulas. P n ≥ 2.0 × 10 10 h / d 0.6 1 1 + exp β + θ − 58 + 1 − 4 L − 7 , β + θ ≥ 60 ° , L ≥ 20 ⁢ mm
