Background

Industry Applications

The metallurgical industry refers to the exploration, extraction, processing, smelting, and rolling of metal ores, encompassing both ferrous metallurgy (steel industry) and non-ferrous metallurgy. It is an important raw materials industrial sector. In the metallurgical industry, temperature control is critical, as most metals have high melting points and the production process requires high-temperature smelting. Therefore, high-temperature measuring devices are essential. Industrial thermocouples for contact temperature measurement have advantages such as simple structure, long service life, and ease of installation. When paired with high-temperature resistant ceramic sheaths, they can measure temperatures up to 1600°C. For materials containing highly corrosive substances, such as aluminum and copper liquids, our company's specially developed metals offer high-temperature resistance, oxidation resistance, and corrosion resistance, significantly extending the lifespan of thermometers.
