  • Method for cooling continuous casting
    Patent number: 4424855
    Abstract: In the equipment for continuous casting of steel, an improved method for cooling a continuous cast slab or the like by which a hot slab can be transferred directly to a rolling step. In accordance with the improved method, the continuous cast slab is subjected to indirect cooling by means of cooling a series of guide rolls with a gas-liquid mist, or if the equipment length is limited, the slab is subjected to direct cooling by means of a gas-liquid mist cooling step, and then to the indirect cooling step in a subsequent process.
