The invention relates to a spiral nozzle used in controlled rolling and controlled cooling technology and a spiral type water feeding method. A water feeding chamber and a turbulence pipe are matched for use. The spiral nozzle comprises a nozzle body and an adjustable spiral type circular seam which is arranged in the periphery direction of the outer wall of the nozzle body. Cooling media are sprayed into the turbulence pipe in the adjustable spiral type circular seam direction through fixed tangent kinetic energy. Through the adjustable spiral type circular seam, the cooling media enter the turbulence pipe under large pressure in the adjustable spiral type circular seam direction through large tangent kinetic energy. By tangent flowing of the cooling media, heat exchanging speed of the cooling media and high-temperature rolled pieces is greatly improved, steel surfaces and core part grain growth can be effectively avoided, the strength is improved, and meanwhile other performance is obviously improved. Meanwhile, the spiral nozzle is small, energy consumption is lowered, cooling capacity is improved, a corrosion resistant coating layer is sprayed on the surface of the nozzle, and the corrosion resistance of the nozzle is improved.
