“Korea Institute of Materials Science Expands Vacuum Processing Capabilities The Korea Institute of Materials Science (KIMS), a government-funded research institute under the Ministry of Science and ICT, has invested in a new NITREX vacuum furnace to bolster its vacuum heat-treating capabilities.

KIMS conducts a wide range of technological R&D activities, including process improvements, application development, material enhancement, testing, and evaluation, to advance Korea’s scientific and industrial research and the country’s industrial capabilities. The new NITREX vacuum furnace will support domestic companies, including Hanwha Aerospace, Doosan Enerbility, Sung-il Turbine, and Samjeong Turbine, in a development project that aims to improve the cycle efficiency of industrial land-based gas turbines.

The NITREX vacuum furnace is a horizontal type 2-Bar external quench equipped with a curved Moly wide band heating element arranged in a circular configuration around the main hot zone. This exclusive free-floating design ensures optimum temperature uniformity throughout the chamber. Since the heating elements are in free movement during thermal expansion, there are fewer instances of breakage, twisting, or premature failures. Its work area measures 15″ in width by 15″ in height by 24″ in length (381 x 381 x 610 mm), and it has a heavy-duty “TZM” Molybdenum hearth assembly that supports high temperatures.

The furnace’s ability to process superalloy and high-performance alloy components and enhance their structural and surface integrity is especially important for KIMS. “The NITREX system not only offers this metallurgical advantage but is also robust, capable of running for years, and can support a wider range of R&D projects and metals,” said Nikola Dzepina, NitrexRegional Manager – Asia. “With the ability to achieve higher vacuum levelswith 10-6 Torr ultimate range, the furnace can heat-treat parts at temperatures up to 1,371°C (2,500°F), making it an excellent choice for processing parts that operate in extreme environments such as those found in the aerospace and precision part industries.” The installation and startup were overseen by NITREX’s local representative, Aerotech. The vacuum furnace has been in operation since December 2022.”
