Precautions for application of refractory cement

When refractory cement is used for baking in industrial kilns, the following matters must be paid attention to:
1.At the normal temperature stage of 350°C, local bursting is most likely to occur, so special attention should be paid to slow baking. If a large amount of steam still emerges after insulation at 350℃, the heating rate should still be slowed down.
2.Under conditions where ventilation is poor and water vapor cannot be easily discharged, the heat preservation time should be appropriately extended.
3.When baking with heavy oil, be careful not to spray heavy oil on the surface of the furnace lining to prevent local bursting.
4.When baking with firewood, direct contact with the flame often causes excessive local heating and should be protected.
5.For newly poured refractory cement, it must be baked for at least 3 hours.
6.The cooling of the refractory cement furnace lining should also be slow and forced ventilation should be avoided.
