  • Patent number: 9321084
    Abstract: A descaling nozzle that can efficiently remove scale from a steel sheet. A spray section at an end of the descaling nozzle includes a taper portion continuous with a large diameter portion that forms a cylindrical channel, a first orifice formed on an outlet side of the taper portion, a resonant chamber continuous with an outlet side of the first orifice and that has a dimension in a radial direction that is greater than a major axis of the first orifice, and a second orifice formed on an outlet side of the resonant chamber.

  • Patent number: 9216446
    Abstract: Provided is a descaling nozzle that can efficiently remove scale from a steel sheet. A discharge section at an end of a descaling nozzle includes a discharge hole (main flow orifice) and a branch hole (branch flow orifice) that are connected to a large diameter portion that forms a cylindrical channel. The branch flow orifice discharges a part of water flow in the large diameter portion so that cavitation occurs at a boundary between the part of water flow discharged from the branch flow orifice and water flow that is discharged from the discharge hole.

  • Patent number: 7367518
    Abstract: A nozzle orifice of a nozzle (1) includes a tapered segment (16) extending from an elliptical discharge orifice (15) and having a taper angle ? of 30 to 80°, and a large-diameter segment (18) continuing with the tapered segment. The ratio of the inner diameter of large-diameter segment (18) relative to the minor diameter of the discharge orifice (15) is not less than 3 and less than 7. Also, the discharge how from the nozzle spreads in a single direction (width direction) within a plane perpendicular to the central axis of the nozzle and the erosion thickness angle is 1.5 to 3° in the direction (thickness direction), perpendicular to the width direction. Such a descaling nozzle enables that scale is removed efficiently at low pressure and/or low flow rate while restraining the cooling of a steel plate.

    Abstract: A nozzle orifice of a nozzle 1 comprises a tapered segment 16 extending from an elliptical discharge orifice 15 and having a taper angle ? of 30 to 80°, and a large-diameter segment 18 continuing with the tapered segment, and scale on a steel plate is removed by discharging water from the nozzle at a distance between discharge orifice 15 and the steel plate of not more than 600 mm, a pressure of 5 to 30 MPa, and a discharge flow rate of 40 to 200 l/minute. The ratio of the inner diameter of large-diameter segment 18 relative to the minor diameter of the discharge orifice 15 is not less than 3 and less than 7. Also, the discharge flow from the nozzle spreads in a single direction (width direction) within a plane perpendicular to the central axis of the nozzle and the erosion thickness angle is 1.5 to 30 in the direction (thickness direction) perpendicular to the width direction.

  • Publication number: 20030027095
    Abstract: A method of controlling a furnace pressure for preventing air from intruding to a heating furnace, a method of stable operation during low combustion load of heat regenerating burners and a method of measuring concentration of an atmospheric gas in a heating furnace are proposed. When the heat recovered with burners each attached with a heat regeneration body is used for heating the combustion air of burners at a combustion state, the suction ratio of the exhaust gas from the burners to the heat regeneration body is adjusted to control the furnace pressure in accordance with a combustion load on an entire heating furnace. The furnace pressure is controlled by adjusting the flow rate of dilution air in accordance with the temperature of the exhaust gas in the exhaust stack on the inlet side of a recuperator in the heating furnace and the combustion load on the heating furnace.

  • Patent number: 6007761
    Abstract: A continuous heat treating furnace in which heat is efficiently recovered from the combustion exhaust gas from the heating section of a continuous annealing furnace. The continuous annealing furnace of the metal strip is a heating furnace or a heating device provided with plural burners for heating to a predetermined temperature a steel material or a continuously supplied metal strip by means of combustion of the burners; a regenerative heat exchanger for collecting a sensible heat of a combustion exhaust gas of the burners, reserving the heat in a regenerator and supplying a predetermined gas to the regenerator to recover the heat to the predetermined gas; and a preheating section for blowing the predetermined gas from the regenerative heat exchanger to the metal strip for preheating. The heat exchanger body is divided into at least three sections, each section having a regenerator.
