NHD-II-16 Pyrometric Cone Equivalent Refractoriness Test Furnace
The electric furnace is a discontinuous running box-type high temperature furnace with a molybdenum rod heating unit. It is used in refractory temperature detection for refractory laboratories, engineering mining enterprises, scientific research institutions, etc.
Furnace temperature can be measured, indicated and controlled. The equipment meets the requirements of GB/T 7322-2017 Refractory products-Determination of refractoriness and EN 993-12, ISO528-1983 Refractory products; Determination of pyrometric cone equivalent (refractoriness). This equipment is used in testing the degree of fire resistance of refractories. Its measuring range is 1580~1800℃.

Q: What is the maximum rated temperature of the NHD-II-16 furnace?
A: The rated temperature of the furnace is 1650℃, with a refractoriness measuring range from 1580℃ up to 1800℃.
Q: Which standards does this refractoriness test furnace meet?
A: The equipment fully meets the standards of GB/T 7322-2017, EN 993-12, and ISO528-1983 for determining the pyrometric cone equivalent of refractory products.
Q: How is the high-temperature bending of the sample monitored?
A: It features an observation hole equipped with a CCD camera system (with an infrared filter and over 10 million pixels, color) to capture and display the real-time shape of the sample on a computer screen.
Q: What are the sample size and operational specifications?
A: The test requires a triangle cone sample with a breadth of 10–20mm. During the test, the cone rotates at a speed of 3–5 r/min.
