"Production Method Of Hot Rolled Steel Sheet"

Abstract: The present invention is a method of descaling a steel material which removes scale formed at the time of hot rolling a steel material by spraying jets of high pressure water from a plurality of nozzles on to the surface of the steel material, the method of descaling a steel material comprising giving pulsation of a frequency of 3.0 kHz to 200 kHz by direct vibration by a vibrator or vibration due to resonance to the high pressure water and setting a distance from each nozzle to the steel slab at 50 to 700 mm in range. Due to this, there is provided a method of producing a hot rolled steel material of a sufficiently good quality removing scale from a difficult-to-descale steel slab such as high Si steel without requiring high pressure water of an extremely high discharge pressure and while easing temperature restrictions on the heating furnace.
