Description

Technical Field

[0001] The utility model belongs to the technical field related to alloy plates, and particularly relates to a heating device for detecting high-temperature oxidation resistance of a stainless steel alloy plate. Background Art

[0002] Stainless steel is steel with stainless and corrosion resistance as its main characteristics, and the chromium content is at least 10.5% and the carbon content is no more than 1.2%. Stainless steel is the abbreviation of stainless acid-resistant steel. Steels that are resistant to weak corrosive media such as air, steam, and water or have stainless properties are called stainless steels; and steels that are resistant to chemical corrosive media (acids, alkalis, salts, etc.) are called acid-resistant steels. Due to the difference in chemical composition between the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical media corrosion, while acid-resistant steel is generally rust-resistant. The term "stainless steel" does not simply refer to one type of stainless steel, but refers to more than one hundred types of industrial stainless steels. Each stainless steel developed has its specific The key to success is to first clarify the purpose and then determine the correct steel grade. There are usually only six types of steel related to the application field of building structure. They all contain 17-22% chromium. The better steel grades also contain nickel. Adding molybdenum can further improve atmospheric corrosion resistance. Among them, the synthesized stainless steel is processed into plates, which is a more commonly used raw material for component processing. It can be processed into various components in various ways. When it needs to face high-temperature working environment, its high-temperature oxidation resistance needs to be determined to determine the applicability of the processed components to the working environment. Therefore, oxidation resistance test heating is required, but it still has the following disadvantages in actual use:

[0003] 1. When the stainless steel alloy plate is heated at high temperature for oxidation resistance, the plate is directly placed in the heating structure for heating. The plate is heated. During the heating process, the uniformity of the heating of the plate is different. During operation, the accuracy of the plate detection is not high enough;

[0004] 2. When heating the stainless steel alloy plate for high temperature oxidation resistance, only the heat oxidation state of the plate can be detected after direct heating. However, during the direct heating process on the plate, only heating is performed, and the experimental conditions are relatively limited. Only one experiment can be performed at a time, and it is inconvenient to adjust the experimental environment. Utility Model Content
