Abstract:

In order to clarify thermal insulation performance of spray coating, the finite element method was used to analyze the temperature field of steel plate protected by spray coating under standard heating curve. The temperature field test of steel plate protected by spray coating was carried out. The main thermal parameters of spray coating were analyzed by using the finite element model verified by experiments. The research results showed that the established finite element model can well simulate the change of temperature field of steel plate protected by spray coating. Thermal conductivity is the most important thermal parameter affecting the thermal insulation performance of spray coating. Density and specific heat has limited influence on the thermal insulation performance of spray coating.
