How hot is spread from one end of the metal strip to the other end of the
Mainly through the way of heat transfer, by metal molecular vibration energy transmission to the surrounding molecules to transfer heat
Industry, there are many is given priority to with heat conduction heat transfer process, such as rubber products heat vulcanization, and the heat treatment of steel forgings, etc. In the kiln, heat transfer equipment and the design calculation of heat insulation and the temperature of the catalyst particle distribution analysis, the heat transfer law occupies an important position. In high temperature and high pressure equipment (such as ammonia synthesis tower and the waste heat boiler, etc.) of large-scale ethylene plant design, also need heat transfer law to calculate the equipment temperature distribution of each heat transfer within the partition for thermal stress analysis.
Mainly through the way of heat transfer, by metal molecular vibration energy transmission to the surrounding molecules to transfer heat. Heat conduction is no macroscopic movement at the time of the heat transfer phenomena in the medium, its all can happen in solid, liquid and gas, but strictly speaking, only is the pure heat conduction in solids, and fluid even in static state, which will be due to the temperature gradient caused by the natural convection resulting from the density difference, therefore, the heat convection and heat transfer in the fluid at the same time.
