1. method for producing continuous casting crystalli-zing roll may further comprise the steps,In the roller core upper edge of crystallization roller roller core shaft to drive into, apopore, on the roller core wall, have water-guiding hole, be communicated with into and out of the water hole respectively and roller core outer surface;

  • On the roller core outer surface of crystallization roller, metal tube is installed, respectively through the water-guiding hole on the roller core wall with is communicated with a plurality of cooling circuits of formation into and out of the water hole, formation crystallization roller cooling system;

    Adopt cold air power spraying and coating;

    To drive metallic particles with high-speed impact crystallization roller roller core outer surface greater than the 1.0MPa pressed gas;

    Enough distortion take place and are bonded on crystallization roller roller core surface and the cooling circuit outer surface in metallic particles;

    Filling pore and then form enough coating layer thicknesses cooling circuit is buried fully, and form the crystallization roll sleeve of adequate thickness, accomplish the manufacturing of crystallization roller;

    Wherein, the diameter range of described metallic particles is 0.5um to 100um;

    Described driving gas is nitrogen, air, helium or its mist;

    The gas pressure of described driving gas is 1.0MPa to 5.0MPa;

    Gas flow 15~

    30g/s;

    Described metallic particles stroke speed is a supersonic speed.
