Description

Technical Field

[0001] The utility model relates to the application field of a tundish cover, and more specifically to an assembled tundish cover. Background Art

[0002] The tundish cover is used to cover the tundish, and it has two main functions: one is to isolate the molten steel in the tundish from contact with the atmosphere and cause air absorption by the molten steel, thereby preventing the formation of white spots and oxide inclusions in the steel ingot during the casting process; the other is to serve as a working platform for operators when blowing the refining ladle water outlet, and to block the thermal radiation of high-temperature molten steel from causing thermal damage to operators.

[0003] Some tundish covers in the prior art often use a long plate to cover the entire tundish. If some parts are damaged during long-term use, the entire long plate needs to be replaced, which increases maintenance costs and reduces overall processing efficiency. Improvements are needed. In view of this, we propose an assembled tundish cover. Utility Model Content
