VBF-1600X-D2 1600°C Automatic Bottom Loading Furnace with Sliding Baffle Door for Thermal Shock Cycling of Alloys
The VBF-1600X-D2 is engineered specifically for conducting thermal shock tests on alloy materials, where rapid and controlled heating and cooling cycles are critical. This bottom loading furnace facilitates efficient sample handling by allowing the sample to be loaded and unloaded from the bottom, minimizing heat loss and exposure time. Its design supports precise thermal cycling up to 1600°C, making it suitable for evaluating material durability under extreme temperature fluctuations.
Operating on a principle of controlled thermal shock cycling, the furnace uses a motor-driven bottom loading stage combined with a horizontal sliding baffle door to manage heat radiation and sample transfer. The baffle door can be closed to preheat the chamber before sample insertion, enabling rapid heating. After heating, the door opens to allow the sample to be lowered out, followed by air cooling via built-in fans for fast temperature reduction. This cycle can be programmed up to 100 repetitions for automated testing.
