Description

technical field

[0001] The present invention relates to a heating device and a heating method inside a refractory container that is used in a molten metal container, a tundish, etc., and at least the inner surface side is made of a refractory material. In particular, it is characterized in that when heating the inside of the refractory container, the temperature rise inside the refractory container can be appropriately controlled so that the entire interior of the refractory container can be appropriately heated. Background technique

[0002] Conventionally, in a refractory container in which at least the inner surface side is made of a refractory material used in a molten metal container, a tundish, etc., the refractory material on the inner surface side is periodically replaced.

[0003] And, when the refractory on the inner surface side of the refractory container is replaced as described above, a cover material is provided above the refractory container, and a burner for...
