The high-temperature wear-resistant thermocouple produced by Shanghai Automation Instrument Co., Ltd. is specially designed for high temperature and strong wear environments such as power plants, cement plants, chemical smelters, etc. Its core advantage lies in the use of independently developed high-temperature wear-resistant materialsMaterial, combined with precision manufacturing technology, ensures long-term stable operation under extreme working conditions, with a service life that can reach leading domestic standardsPing. Typical application scenarios include circulating fluidized bed boilers, coal mills, and cement clinker kiln heads/Measurement of high-temperature powder temperature for equipment such as kiln tail.

Core technical features

Material Innovation

High temperature wear-resistant alloy: jointly developed by Shanghai Automation and domestic material research institutions, using vacuum smelting technology, forged as a whole through drilling or deep blind hole one-time forming. This material has high hardness at high temperatures（HRC58-62）With excellent toughness and impact resistance, the service life is longer than traditional materials50%The above.

Composite casting wear-resistant alloy: using high-temperature alloy as the matrix, adding wear-resistant particles for precision casting, with high hardness and resistance to high-temperature oxidation of the casing, suitable for800-1200℃Temperature measurement scenario.

Ion implantation of tungsten carbide: Using stainless steel as the substrate, tungsten carbide particles are injected onto the surface through particle injection technology to form0.5-1.5mmWear resistant layer, hard on the outside and tough on the inside, with a lifespan of up to2Years or more.

manufacturing process

Deep blind hole processing: imported from GermanyTBTThe company's deep hole drilling technology ensures smooth inner wall protection and reduces stress concentration.

Fully automatic welding: using GermanyEWMThe company's argon arc welding technology has high welding strength and good airtightness, avoiding weld cracking at high temperatures.

Precision straightening: By using multiple cold drawing straightening processes, the straightness of the thermocouple is ensured≤0.5mm/mReduce installation stress.

performance parameters

Temperature measurement range:0-1300℃(Nickel chromium)-Nickel siliconKType division number), some models can reach1600℃（SiCMaterial).
