It can be seen that copper is a well-deserved good material. The heat conduction effect is junior and does not store heat. Brass is the second,wok pan and the performance of wrought iron is more moderate. Although the heat conduction is worse,wok pan the specific heat is not high and will not be added.
Store heat. The performance of cast iron is relatively poor, the specific heat is average and the thermal conductivity is poor, while the aluminum is relatively special,wok pan the thermal conductivity is excellent and the specific heat is extremely high, and it can store quite a lot of heat. This special property makes it also have a unique way of use. The thermal conductivity of stainless steel is extremely poor,wok pan the specific heat is high,wok pan and it is not as thick as a cast iron pot, and a proper paste pot is a little expert.
The temperature of the flame core of the domestic natural gas stove is 800-1000 degrees,wok pan and the temperature of the side flame is between 1300-1500 degrees. The process of heating the pot (not limited to the wok) is as follows (the temperature range divided to better explain the situation of each stage,wok pan a rough estimate, not accurate):
Initial heating stage (0℃-100℃): The flame heats the bottom of the pot, and the temperature is transferred to the edge of the pot. The pot made of materials with low thermal conductivity cannot be too thin. If the heat is too thin, the temperature of the bottom of the pot will have risen. High to a relatively high level,wok pan it is easy to burn or paste the pot. The material with good thermal conductivity should be as thick as possible while taking into account the weight,wok pan so as to avoid the excessive temperature difference between the bottom of the pot and the side of the pot.
At this stage,wok pan because the temperature difference between the fire and the wok is relatively large, it is easier to raise the temperature,wok pan and the synchronization rate of the temperature increase of the whole body is relatively high.
