Precautions for baking the tundish heater
2025-11-29
For the baking of tundish dryers, the general requirement is that they must be baked before starting the casting. 1~2 Within hours. Quick baking to 1000~1100 °C is preferable. This saves energy and makes it easier to use.
For continuous casting of slabs, aluminum-carbon monolithic stoppers or monolithic aluminum-bonded submerged nozzles have already been installed on the tundish heater. If the heating process is prolonged, the strength of the products will decrease. ; If the anti-oxidation coating on the surface of the product is inadequate, the product will become oxidized and porous, not only further reducing its strength but also shortening its service life. According to Zhongwei Company’s experience, for submerged nozzles, under the condition that their wall thickness can no longer be increased, extending their service life primarily depends on whether their surfaces have been oxidized.
During the baking process, the strength variation pattern of aluminum-carbon products is as follows: : As the baking temperature increases, the strength of the product decreases, to... 500~600 Between ℃, low intensity : As the temperature continues to rise , The strength of the product increases to 1300 When the temperature is restored to its original level around ℃, further raising the temperature causes the strength of the product to decline again. For this reason, it is essential to bake rapidly to reach the predetermined temperature.
