Abstract
Description
[0001] Field:
[0002] The invention relates to a low-temperature drop ladle pouring method, which is mainly applicable to steelmaking plants in the metallurgical industry. Background technique:
[0003] Nowadays, most metallurgical enterprises have realized full continuous casting. During the casting process of the continuous casting machine, the molten steel stays in the ladle for a long time, and the temperature drop of the molten steel in the ladle and the ladle itself is relatively large during the pouring process. The continuous casting process itself requires stable temperature of molten steel and stable superheat of molten steel in the tundish. Only when the superheat of molten steel is stable can the casting machine operate smoothly.
[0004] The pouring time of continuous casting ladle is generally more than 30 minutes. The difference between the highest superheat and the lowest superheat of a furnace of steel in the pouring process is generally 6-13 degrees, that is...
