Bone China Functional ceramic mugs
In the heat transfer process, if the object is a point in the unit time of heat is exactly equal to its spread out heat, thermal equilibrium is reached, this temperature is maintained. Heat transfer process in the heat and exothermic phase equilibrium, we called the steady heat transfer. Conversely, if a point of the heat and let out the heat imbalance, the temperature will rise or reduce the point. The heat transfer in the process and heat imbalance, we call it the unsteady heat transfer.
Tunnel kiln, kiln, kiln roof wall temperature of each point is basically stable. In this case, the heat transfer process of kiln heat through the kiln, kiln wall top outward dissipation, can be seen as a stable heat transfer; and the kiln products, heating and cooling, heating and cooling of the kiln car, belonging to the unsteady heat transfer process.
