1700°C Lifting Furnace
This lifting furnace system is used for heat treatment experiments in air at temperatures up to 1700°C, as well as for nanomaterial preparation and ceramic sintering. The furnace chamber is constructed of alumina polycrystalline fiber imported from Japan, with a circular chamber and silicon-molybdenum rods distributed around the perimeter. The furnace temperature is uniformly maintained within ±3°C, making it ideal for sintering non-metallic materials with demanding temperature profiles. A precision lead screw provides linear, electric lift, ensuring smooth and vibration-free movement of the furnace bottom. A servo motor provides adjustable lifting speed. A large-screen PID temperature controller displays temperature curves.

A 20-tonne Acheson graphitization furnace can hold full power for 24 to 40 hours and then need five to seven days of cooling before anyone opens it. Peak temperature is the headline number, but cost per tonne is decided by three quieter things: the furnace type, the condition of the insulation, and the shape of the power profile. Two shops running the same 2800 °C schedule can differ by 30 percent in kilowatt-hours per tonne. The gap is usually not the transformer. It is compressed graphite fel...
