Manufacturing technology for aluminized iron pan

Abstract

The invention provides a manufacturing technology for an aluminized iron pan. The manufacturing technology comprises the first step of tensioning, wherein a prepared aluminized steel plate is placed on a hydraulic machine after being punched, pressurization is performed so that pressure can reach 10-12 MPa, and a pan body blank is formed, the second step of cutting edges, wherein the pressurized and formed pan body blank is placed on a barometric bead cutter, and redundant materials at the opening of the pan body blank are cut off, the third step of performing degreasing and cleaning, wherein the pan body is placed on a special cleaning line for the aluminum pan after the redundant materials at the opening are cut off, and drying is performed after degreasing, spraying with warm water and spraying and cleaning with clear water, and the fourth step of performing high-temperature thermal diffusion, wherein the dried pan body is placed into a high-temperature furnace with the temperature at 760 DEG C, high-temperature oxidation heat diffusion processing is carried out for 7-8 minutes, and the pan body is taken out of the furnace for wind cooling. Due to the adoption of the manufacturing technology for the aluminized iron pan, equipment and operation are simple, the technology is stable, the process is easy to control, cost is low, and meanwhile the manufacturing technology meets the requirements for environmental protection. Moreover, in the production process, an obvious pollution source will not be produced. Besides, the bonding strength between an aluminized layer and a base is increased, and the aluminized layer is prevented from peeling off and the like.

Description

technical field [0001] The invention belongs to the technical field of kitchen utensil manufacturing, in particular to a manufacturing process of an aluminized iron pan. Background technique [0002] Pots are indispensable kitchen supplies in life, and can be roughly divided into: iron pots (including cast iron pots and wrought iron pots), aluminum pots, aluminum alloy pots, stainless steel pots, etc. Pig iron pots are bulky, and cooked iron pots are prone to oxidation at high temperatures and have a short lifespan; pig iron pots can supplement the iron elements needed by the human body, which is beneficial to human health. Aluminum pots, aluminum alloy pots, and stainless steel pots have better performance, but they are considered harmful to human health for long-term use. The coating in the non-stick pan is not resistant to high temperature and metal spatula, and it is not suitable for Chinese eating habits. There are also many anti-rust iron pots on the market that are ...

AI Technical Summary

Problems solved by technology

There are also many anti-rust iron pots on the market that are treated with steel nitriding technology. Although they can also solve the rust problem in some cases, their comprehensive performance of acid resistance and salt water corrosion resistance is poor, and the film layer on the surface is easy to fade. After use, the iron base layer is prone to pitting corrosion penetration
