Non-sticky nonrust iron pan and manufacturing method thereof

Abstract

The invention discloses a non-sticky nonrust iron pan, comprising a metal base, wherein a FeCr chromium carbide or NiCr chromium carbide or CoCr chromium carbide metal material layer is meltallized on the working surface of the metal base, a non-sticky layer which is provided with micro holes and is easy to clean is formed, and a nitriding layer is formed on the surface of the metal base communicated with the micro holes by virtue of nitriding treatment. The invention also discloses a method for manufacturing the non-sticky nonrust iron pan, comprising the following steps: (1) cutting, stretching, removing oil and cleaning, decontaminating and dewaxing, and stoving; (2) coarsening; (3) forming the non-sticky layer which is easy to clean on the working surface; (4) forming the nitriding layer by the nitriding treatment; and (5) carrying out cleaning, stoving and the like. The non-sticky nonrust iron pan disclosed by the invention has the advantages of sticky resistance, rust resistance, white appearance, energy conversation and the like.

Description

technical field [0001] The invention relates to a kitchen utensil and a manufacturing method thereof, in particular to a non-stick and stainless iron pan and a manufacturing method thereof. Background technique [0002] People have developed non-stick pans for decades, and now they have achieved a lot. The earliest is to coat a layer of non-metallic materials such as polyfluororesin on the working surface of the pot. This kind of non-stick pan is not easy to fall off due to the low temperature resistance of polyfluororesin, the low bonding force between polyfluororesin and the main body of the pot, and the fact that polyfluororesin is not easy to fall off. The service life of fluororesin is not long due to wear resistance and damage, usually only about 6 months. Later, Chinese patent document CN100459910C discloses a metal non-stick coating cooking utensil. On the body material of the pot, a layer of nickel-aluminum-molybdenum alloy or chromium carbide-based nickel-chromium...

Problems solved by technology

Later, Chinese patent document CN100459910C discloses a metal non-stick coating cooking utensil. On the body material of the pot, a layer of nickel-aluminum-molybdenum alloy or chromium carbide-based nickel-chromium-chromium carbide alloy is sprayed on the body material of the pot. The non-stick layer has the advantages of impact resistance, high temperature resistance and wear resistance, but if the body material of this pot is iron, it is very easy to rust, which brings a lot of inconvenience to the user

Even if the body material of the pot is made of stainless steel, since the non-stick layer is formed by spraying at about 500°C, some stainless steel will reduce the anti-rust function after this temperature, so that the whole pot cannot be completely rust-proof, and the cost of stainless steel is relatively high. Non-stick pan products are not easy to promote and use

Of course, there are also many anti-rust iron pans in the market, including iron pans that have been treated with nitriding. Although this type of iron pan has a good anti-rust function, it has the following defects: (1) First, it cannot prevent sticking. Inconvenient; (2) After nitriding, it is brittle and easy to break; (3) After nitriding, the surface is dark and dull, and the appearance is not beautiful; (4) It consumes a lot of energy and is not energy-saving

[0003] In addition, although there are non-stick pans and stainless pans on the market, so far, there is no iron pan that can prevent sticking and rust, and can also save energy.
