Compared with traditional mould refractory castable casting, CCM can improve metal recycle rate and low down power consumption. CCM can make the melting work simple and short the melting time, in which way the production efficiency can improve in a large degree. Tundish is a middle progress of steel making, and it is the kep point which can decide continues casting or not. Furthermore, tundish would have a big effect on melten refractory material steel quantity and quality. Its functions are as following:
1. Diversion. For multi-strand CCM machine, the melten steel would be divided from tundish.
2. Continues casting. When refractory firebrick multi-furnace continuous casting, tundish can be a holder when changing ladle.
3. Lowing down presure.
4. Protecting melten steel quality. Through using covering agent, long nozzle and other protecting device, tundish can help to protect the melten steel quality.
