What kind of refractory brick is used for the tundish?

The tundish is a high-temperature container made of refractory materials. The refractory products used for the lining of the tundish are refractory bricks, refractory castables, heat-insulating bricks, etc. Today, Sunrise refractory materials introduces the material used for the tundish lining. Refractory bricks, please see the details below.

 

The function of the tundish is to stabilize the temperature of the molten steel, so that the molten steel can be floated up. When the molten steel is short-lived or the ladle is replaced, the continuous casting can be guaranteed to go straight. Generally, the capacity of the tundish is 15%-30% of the ladle. Each caster is equipped with 7-12 tundishes. The tundish has two forms, a T shape and a boat shape.

The temperature of the molten steel in the tundish is 1510~1570°C, the service life of the permanent lining is 200~1000 times, and the foreign ones reach 1000 times. The eroded lining should reach a continuous pouring and easy to turn over. Generally, the service life of special steel tundish is 2~10h, and the service life of the intermediate bag of ordinary carbon steel is increasing, which has reached 20~40h, and some have reached more than 70h.
