Refractoriness Test Furnace
Published: 3/14/2025
Periodic box-type high-temperature furnace using molybdenum rods to determine the refractoriness of refractory materials. Suitable for laboratories, industrial plants, and research institutes with a measurement range of 1580–1800°C.
Product Description
The NHD-II-17 Refractoriness Test Furnace is a periodic, box-type high-temperature furnace that uses molybdenum rod heating elements for precise temperature measurement, indication, and control during refractoriness testing. It is designed for refractory materials laboratories, industrial quality control, and research institutions to evaluate the softening behavior of standard triangular cone samples under controlled heating and rotation.
The system supports standard graphite or optional alumina sample holders and integrates observation capability for visual assessment of cone deformation in accordance with GB/T 7322-1997. Multiple rated temperature configurations are available to match different test requirements, and the unit provides stable rotational motion of the cone plate to ensure uniform thermal exposure.
