In a method for continuous casting of steel, a slab having good quality is obtained by inspecting the profile of the unsolidified region of the slab in the transverse direction thereof during casting and controlling the cooling pattern so that the profile matches a pre-determined standard profile.

Method for continuous casting of steel

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.
