Process for manufacturing frying pan

A process for manufacturing a frying pan, comprising the following steps of:

• (1) material selecting:
• selecting a cold-rolled plate/hot-rolled plate as a basic plate;
• (2) cutting:
• cutting the basic plate into a compliant plate according to a specification required by frying pan machining;
• (3) machining and forming:
• die-cutting and bending the plate to obtain a pre-formed frying pan;
• (4) welding:
• welding side seams present at bends of the pre-formed frying pan, and meanwhile welding a fixed base to the bottom of the pre-formed frying pan;
• (5) grinding:
• grinding burrs, welding bumps and welding marks on the frying pan obtained from the previous step, and shaping uneven parts of the frying pan to keep the frying pan even;
• (6) sanding:
• sanding and blasting six faces of the frying pan ground in Step (5) with brown fused alumina sand;
• (7) cleaning:
• cleaning the sanded frying pan;
• (8) baking:
• baking the frying pan cleaned to remove moisture on the surface of the frying pan;
• (9) preparing a ceramic paint:
• preparing a ceramic paint consisting of a primer and a finish paint, for painting the frying pan;
• (10) spraying of the ceramic paint:
• preheating the frying pan obtained from Step (8) to 70° C., monitoring a surface temperature of the frying pan by using an infrared thermometer, and spraying the frying pan with the primer and the finish paint prepared in Step (9) when detecting that the surface temperature of the frying pan reaches 30-40° C., wherein spraying a layer of the primer at first, leveling after the spraying of the primer, standing for 2-3 minutes, and then spraying the finish paint directly;
• (11) curing:
• after the painted surface of the frying pan is dried, baking and curing the painted surface;
• and
• (12) cooling:
• naturally cooling the frying pan cured to obtain a finished frying pan.
