Abstract
There is provided a liquid removal device that removes liquid attached to a surface of a steel sheet, the device including a slit nozzle that jets gas to the surface of the sheet, the slit nozzle being installed so as to jet gas from a downstream side toward an upstream side in a movement direction of the sheet that moves relatively to the slit nozzle and being configured in a manner that a jet angle θ, a back face inclination angle β, and a back face length L of a nozzle back face of the slit nozzle satisfy, β+θ≥° and L≥mm, and a gap h between a jetting port of the slit nozzle and the sheet, a slit width d, and nozzle pressure Pof the slit nozzle satisfy the following relationship: P(h/d){(+exp(β+θ−)+}L.
