Matters need attention for the sintering of tundish lining

To save cost and make it easy to use, it’s better to make a fast sintering to increase the temperature in tundish to 1000-1100℃ 1 to 2 hours before it is put into use.
For slab continuous casting, normally Al-C monoblock stopper or integrated Al-C submerged entry nozzle would apply with tundish. If the sintering is too long, the strength of monoblock stopper and SEN will be lowered, if they are with bad anti oxidizing coatings, they could be oxidized, which will further lower their strength and service life.

The changing rules of the strength of aluminium carbon products during sintering is: With the increasing of sintering temperature, the strength goes down, when the temperture is between 500℃ to 600℃, it has the lowest strength. When the temperature goes up again, the strength will go up, when the temperature is 1300℃, it will go back to original level, but when the temperature rise again, the strength will go down. For this reason, it is required that the sintering should be fast to get the preset temperature asap.

Delelopment of continues casting & tundish

CCM first appear in 1950s, it is characterized by fast casting and focus investment. CCM technology was developing in a very fast speed. In Year 1970, CCM only took 5.6% all over the world, while the data reached 62.4% in Year 1990, and in some developed countries, it was even 95%. In recent years, many steel plants adapted CCM instead of mould casting. Until Year 1994, in total 24 countries are of full CCM now.

Compared with traditional mould 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 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 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.
