Wear-resistant thermocouple is made of different types of wear-resistant thermocouple protection tubes made of different materials such as plasma painting technology, high-chromium cast iron and high-temperature alloy. They are specially designed for high-, medium-, low-temperature wear-resistant environment measurement applications. In the circulating fluidized bed, boiling furnace, cement rotary kiln tail smoke chamber. Compared with ordinary thermocouples, the service life is greatly improved. The materials of wear-resistant thermocouple thermowells can be divided into the following three categories, and each has its own unique characteristics: 1. Wear-resistant high-temperature alloy: According to the characteristics of high-temperature wear environment, specially designed high-alloy alloy with high-temperature oxidation resistance and high-temperature high-strength special wear-resistant high-temperature alloy. Less processing defects, high reliability, high temperature strength and wear resistance, good overall performance, high price, use temperature 800 ~ 1200 °C. 2, composite casting wear-resistant alloy: the use of composite armor technology to join the wear-resistant particles in the high-temperature alloy matrix, precision casting. No need for turning processing, high hardness of casing, high temperature oxidation resistance, little casting defects but not affecting high temperature wear resistance and sealing. It is the most common high temperature wear resistant casing, and the price is moderate, the use temperature is 800~1200 °C. 3. Ion-injection tungsten carbide: Injecting tungsten carbide particles on the surface of the casing by ion infiltration technique using stainless steel as the matrix. With high hardness, high strength, high toughness, especially wear-resistant, wear-resistant layer thickness 0.5 ~ 1.5mm, external hard and tough, minimum diameter can be φ8, surface quality is good, use temperature 0 ~ 800 ° C, in power plant coal mill It is widely used and has a service life of more than 2 years. Wear-resistant thermocouples are the most ideal measurement temperature sensors for use in high temperature and wear-resistant environments in metallurgical, chemical, cement, power and fluidized bed boiler industries. Different wear-resistant thermocouples are used in different occasions. Welcome to contact us. We are experienced and choose the best wear-resistant thermocouple for different environments.
