refractory high temperature cement life time

September 19, 2020

The choice of refractory high temperature cement can improve the service life of furnace fundamentally.

Therefore, refractory high temperature cement must have quite high refractoriness, volume is more stable, can resist high temperature thermal load, volume does not shrink but can expand uniformly.Must also have a good thermal shock resistance, resistance to rapid changes in temperature, do not crack, do not flake.

To reduce the refractory high temperature cement contained in the hybrid quality, because once the material contains impurities, under the action of high temperature will form a low melting point of the compound, reduce the refractoriness of the refractory.

In addition, the particle size ratio of refractory high temperature cement also has certain provisions. Reasonable ratio can form a high density refractory layer in the process of building the furnace, but also can improve the service life of refractory high temperature cement.
