Embodiment Construction

[0058] 1. Material selection for the main parts of the wok

[0059] The material selection of the main parts of this "non-carcinogenic stainless frying pan": cold-rolled low-carbon steel plates are recommended, for example: carbon structural steels Q195, Q215B, Q215BF, Q215C or Q235B, Q235C are selected according to the Chinese national standard GB / T700 etc.; Select 08, 08F, 10, 10F, 15, 15F, 20 high-quality carbon structural steel according to the Chinese national standard GB / T699-2015. The impurity nickel and chromium content of the material used for the main part of the frying pan should be strictly controlled, and the nickel content should be less than 0.05% after random inspection. According to the diameter of the frying pan (38, 37, 36, 35, 34, 33, 32, 30, 28, 26 cm), cold-rolled steel plates with a thickness of 4.0 to 2.5 mm are selected.

[0060] Because the corrosion resistance of gray cast iron is obviously better than that of steel plate. Therefore, Chinese tradit...

Abstract

The invention belongs to a carcinogenicity-free stainless frying pan of a Chinese cooking segment-shaped frying pan, and relates to a principle and a manufacturing method of the carcinogenicity-free stainless frying pan. According to the principle and the manufacturing method of the carcinogenicity-free stainless frying pan, a 26-38cm small-caliber frying pan main body piece is manufactured by mould pressing of a cold-rolled low-carbon steel plate without carcinogen chromium, nickel, chromium metal, nickel metal and nickel alloy; a large-diameter wok main body part of 56-108 cm is cast by graycast iron and nodular cast iron; and then a nitriding or nitrocarburizing process is adopted for the frying pan main body part which is formed through mould pressing or casting, so that a nitriding layer with the thickness ranging from 0.20 mm to 0.42 mm is generated on the surface of the frying pan, and the nitriding layer has very high abrasion resistance and corrosion resistance. Even if the wok is frequently collided and ground by a metal frying shovel in the frying process, particles enter dishes and are eaten into a digestive system of a human body, and the particles are iron and tracenitrogen and carbon which are harmless to the human body. Due to the fact that the heat conductivity is lower than that of a nitriding layer made of steel, cooking fumes of initial-stage frying oil can be reduced; the anti-sticking tendency is realized, and the cleaning is easy.

Description

[0001] (1) Technical field [0002] Metallology, tumor pathogenesis, tumor epidemiology, preventive oncology, primary cancer prevention, chemical heat treatment nitriding or nitrocarburizing process, applied to kitchen utensils Chinese-style wok. [0003] (2) Background technology [0004] According to the definition of metalology, the concept of "stainless" refers to not rusting in the air, such as stainless steel. [0005] The wok used for Chinese cooking is different from the pan used for western food. The Chinese cooking method is to cook dishes in a spherical metal pot. In order to make the cooked dishes evenly heated in the pot, it is necessary to use a cooking spatula to continuously turn the dishes from the bottom of the pot to the top. For two thousand years, the frying shovel used by Chinese ancestors from generation to generation is basically commonly called "iron shovel" (because it is rusty, it is also called "black iron shovel"), and the frying pan used is common...
