A mold heating device is disclosed. The mold heating device according to one embodiment of the present invention comprises a frame at the top of a mold; and one or more rotatable heating units on the frame to cover the top of the mold with a supporting unit between them. The mold heating device prevents rapid temperature changes caused by a mold flux injected to molten steel on the top of the mold by heating the top of the mold; and improves fluidity by stabilizing the temperature of the mold. Therefore, the quality of a slab is improved. |
