Abstract

The invention belongs to the field of cooker making, and discloses a production process of a mud mold moire-pattern rust-proof cast iron fry pan. The method comprises the following steps that firstly,broken cast iron, cerium metal and metal iridium are mixed according to the proportion and then are added into a smelting furnace to be molten into molten iron, the molten iron is added into a deslagging agent to be subjected to impurity removal, the molten iron is poured into a mud mold to be shaped, and flash, burr and polishing treatment are carried out; secondly, a ground pan body is subjected to manual clean water cleaning, ultrasonic cleaning is carried out, and high-pressure washing is carried out; thirdly, the washed pan body is placed in a nitriding furnace, and two-segment type nitrocarburizing treatment is carried out; and fourthly, the pan body after being discharged is soaked in a sodium hydroxide solution, after air-drying, heat treatment is carried out, after cooling, a panbody polishing machine is used for grinding the surface of the pan body to be smooth, a pan handle is mounted, and a product is obtained. The pan body is subjected to nitrocarburizing treatment, thepan body surface hardness and oxidation resistance capacity are improved, the pan body is not prone to rusting, and is not prone to being scratched by a hard object, and maintaining is simpler.

Description

technical field [0001] The invention belongs to the field of cooking utensils, and in particular relates to a production process of a mud moire-pattern antirust cast iron wok. Background technique [0002] Cast iron pans have a long history and various types. They have the characteristics of solid texture, low price, uniform heat conduction, and durability. Long-term use of cast iron pans for cooking can make the iron contained in the dishes enter into the dishes, thereby being absorbed by the human body, which can improve the health of the human body. The necessary iron element has good social value and economic value. Traditional clay molded cast iron pots, because cast iron is particularly prone to rust, and graphite plays the role of rust prevention and protection of the pot body, in the die-casting process, a layer of graphite powder must be applied to the mold to remove the mold, resulting in a large amount of graphite remaining on the surface of the product . Theref...
