Vacuum atmosphere lifting (lead screw) electric furnace operates at 1200°C for long-term use, with a maximum temperature reaching 1250°C. Both the temperature control accuracy and uniformity are ±1°C. The lead screw lifting loading platform has a load capacity of 0.1-10 tons, supports 50-segment programming, can achieve a vacuum degree of -0.1MPa, and allows for multiple gas atmospheres, making it suitable for high-temperature experimental needs.
