1. From the modeling analysis, the semi-circular wok can ensure uniform heating during cooking, which is beneficial to stir-frying, and will not cause the dishes fried in one pot to taste different, while the pot used in the induction cooker is not evenly heated, which is not conducive to stir-frying.

2. From the material analysis, pig iron has the worst thermal conductivity, followed by aluminum alloy, steel and stainless steel, so it is easier to control the temperature of the raw iron pan.

3. From the point of view of nutrition, it is inevitable that trace metal elements dissolve into vegetables in the process of cooking. Relatively speaking, pig iron does not add trace elements in the smelting process, and trace iron is beneficial and harmless to human body, while other metals are more or less added with other trace elements in the smelting process.
