The translation of "锅体法兰" and "锅盖法兰" into English is "pan body flange" and "lid flange" respectively.

I. Basic Structure of a Flanged Pan

A flanged pan typically refers to a cast iron pan with enamel coating. The edges of the pan body and the lid may adopt a connection similar to a flange to ensure a tight seal between the pan body and the lid. This design helps to retain heat and moisture inside the pan, thereby achieving better cooking results.

II. Characteristics of the Pan Body Flange and Lid Flange

Pan Body Flange:
Usually located on the edge of the pan body, it is designed to mate with the lid flange to achieve a tight seal. The material may be the same as the pan body, such as cast iron, to ensure the strength and durability of the overall structure. It may undergo special treatment, such as enamel coating, to improve its corrosion resistance and aesthetic appearance.

Lid Flange:
Located on the edge of the lid, it corresponds to the pan body flange. It also adopts the same material as the lid to ensure overall seal tightness and durability. The design of the lid flange may consider the convenience of easy opening and closing, as well as ensuring that it will not deform or leak due to pressure during cooking.
