What happens when steel melts?

In order to improve the uniformity of solidification structure of slab and reduce macro segregation, a consumable vibration excited metal liquid nucleation technology is proposed. When the vibrating steel strip is fed with molten steel, mold flux may be involved, so the heat transfer is numerically simulated. The experimental results show that the temperature of the center point of the lower edge can be stabilized above the liquidus temperature of the strip when the superheat is 65438 00℃ and the feed speed is less than 0.36 m/min. When the feeding speed is less than 0. 102 m/min, the temperature at the center of the narrow side of the steel strip with a steel slag interface of more than 2 mm can reach or exceed the melting temperature of the mold flux through axial heat transfer, and the mold flux near the steel strip may be in a molten state at this time, so it will not be brought into the molten steel.
