Nitrided low-carbon steel slice without carcinogenicity

Abstract

The invention provides a nitrided low-carbon steel slice without carcinogenicity. A main body part of the nitrided low-carbon steel slice without carcinogenicity is manufactured by adopting a cold-rolled low-carbon steel plate and the nitriding or nitrocarburizing process is adopted for treatment, so that an infiltrated layer with very strong wear resistance and corrosion resistance which is 0.20-0.42 mm is formed on the work face of the slice. During the dish frying process using the slice, even if the worn particles enter dishes to be ingested into the in-vivo digestive system due to the metal collision type wear inevitably occurring between the slice and a wok, only iron and trace amount of carbon and nitrogen which have no carcinogenicity for the human body exist; a copper handle is designed for increasing the elegance; an asbestos rubber sheet gasket is arranged between the copper handle and a wok rod for realizing thermal insulation.

Description

(1) Technical field [0001] Metallurgy, tumor pathogenesis, chemical heat treatment nitriding or nitrocarburizing process, applied to kitchen utensils and cooking spatulas. (2) Background technology [0002] The diet and cooking methods of the Chinese nation are different from 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 more than two thousand years, the cooking spatula used by Chinese ancestors from generation to generation basically uses the common name "shovel". Commonly known as "iron" belongs to low-carbon steel according to the concept of metallurgy, that is, an alloy composed of elemental iron (Fe) and trace carbon (C). As we all know, ordinary steel is easy to rust in the atmosphere we live in. This kind of rust belongs to electrochemical corrosion. T...

AI Technical Summary

Problems solved by technology

During the cooking operation, when the stainless steel frying shovel is used for cooking, there will inevitably be metal collision wear between the frying pan and the frying pan, so that the carcinogen chromium metal, nickel metal, and nickel alloy particles in the stainless steel frying shovel, which are confirmed by the World Health Organization, enter the dishes and cause Inevitably ingested by family members into the digestive system, threatened by carcinogenic potential
