High aluminum bricks’ making temperature and heat preservation time

Friends who select alumina bricks clearly know how much temperature you need to control when producing alumina bricks? How long the insulation ​​in the future you know? Today let Luoyang Yilong Refractory technician to tell you knowledge of alumina bricks that making temperature and holding time.

1. Alumina bricks are divided into one, two, three grade, and ​​the normal temperature is about 1440 degrees Celsius, holding time can reach 40 hours
2. Making time for high aluminum brick three, temperature should be controlled at 1400 degrees Celsius; the holding time in this case can reach a maximum of 32 hours.
3. And when the tunnel kiln firing high alumina brick, the temperature must be at 1550 degrees, so that the holding time can be in 24 hours or 48 hours.

And according to the temperature and different raw material with high aluminum bricks, baking temperature 600 degrees Celsius is the lowest temperature as the boundary, then in the firing process a little with increasing temperature, and fired refractory brick the required temperature so far.

The content of the temperature and heat preservation time, high alumina brick is how much knowledge you have some understanding of it, if you want more information about high aluminum brick knowledge can consult us.
