Description
Technical Field
[0001] The utility model relates to the technical field of tundish baking in a continuous casting workshop, in particular to a tundish with good sealing effect. Background Art
[0002] The baking of the tundish in the current continuous casting workshop is a major gas consumer. Due to external and production organization reasons, the baking time of continuous casting is quite arbitrary, which can easily result in a long baking time. During the baking process of the tundish, there is a gap between the tundish cover and the tundish, and the tundish cover is not automatically fitted and limited when the tundish cover is closed to achieve sealing. As a result, flames are likely to overflow during the baking process, which can easily splash onto the workers and cause danger. In addition, the gap between the tundish cover and the tundish can easily cause heat loss, which can prolong the baking time, increase gas consumption, and increase production costs.
