quick replace tundish nozzle has been applied more and more widely. Under the change of continuous casting process, the qualified rate of quick replace Tundish nozzle is increasing, which reduces energy consumption. The following Xiaobian will introduce the advantages of quick water change in the tundish

1, improve the yield of molten steel
With the rapid replacement of sizing nozzle technology for continuous casting tundish, the number of continuous casting furnace increases, the number of continuous casting starts decreases, the amount of cut end and cut end waste of tundish and billet decreases, and the recovery rate of molten steel increases.
2, improve the quality of casting billet
The quality of the billet is greatly affected by the number of the first and the second ladle of tundish. The increase of the number of ladle in a single ladle reduces the number of times entering the first ladle and the second ladle of tundish, thus improving the quality of the billet.
3. Stable production organization
Before the use of quick change, the drawing speed is unstable and unpredictable due to the expansion of the water nozzle, which may lead to accidents or stop pouring at any time, bringing difficulties to the production organization. After using the nozzle quick change technology, not only to avoid the occurrence of similar accidents, but also to save the role of molten steel.
4. Reduced labor intensity
The increase of the number of single-ladle continuous casting furnace reduces the number of tundish masonry and production preparation times, and reduces the labor intensity of workers.
5. Economic benefits
With the increase of the number of continuous casting furnaces, the material cost per ton of steel decreases correspondingly, and the cost per ton of steel decreases.
Main features:
1, sliding fast, accurate, no bias flow, steel leakage
2, good erosion resistance, no obvious expansion, long service life, no drift, scattered flow phenomenon
3, good thermal shock performance, excellent anti-explosion performance
4, according to customer needs to quickly develop heterosexual products
