This furnace requires a stable AC 220V 50/60Hz power supply with 3KW capacity and must be operated within the maximum working temperature of 1150°C. The system supports vacuum or flowing-gas atmospheres and the heating rate must not exceed 10°C per minute to avoid thermal stress.
- Power Supply Requirement: The furnace must be connected to an AC 220V 50/60Hz power source rated at 3KW.
- Temperature Limit: Continuous operation is limited to a maximum working temperature of 1150°C.
- Ramp Rate Limit: The heating rate must be set to no more than 10°C per minute to prevent thermal shock.
- Atmosphere Requirement: The furnace can operate under vacuum or with a flowing inert gas atmosphere.
- Press Load Limit: The maximum press force is 40 tons, applicable to samples up to 100 mm diameter.
Initialize the furnace by verifying power supply, vacuum/gas connections, and die installation. Then program the temperature profile and apply pressure according to the material requirements.
Required Equipment: Vacuum pump, Inert gas supply, Die set
- Inspect Connections
Verify that the AC 220V power supply, vacuum pump, and inert gas lines are properly connected and leak-free. - Load Sample
Place the sample material into the pre-installed die set and center it on the press platform. - Set Atmosphere
Evacuate the chamber or introduce a flowing inert gas to achieve the required processing atmosphere. - Program Temperature
Set the heating rate to no more than 10°C per minute and the target temperature up to 1200°C (working limit 1150°C). - Apply Pressure
Gradually apply the press force up to 40 tons while monitoring the temperature and pressure gauges. - Monitor Process
Maintain the set temperature and pressure for the desired dwell time, recording any deviations. - Cool Down
Allow the furnace to cool naturally or with controlled cooling, then release pressure and retrieve the sample.
Why is the maximum operating temperature rated at 1150 °C when the furnace can reach 1200 °C?
The rated temperature of ≤1150 °C ensures long-term stability and consistent performance for sintering, annealing, and other thermal processes, while the 1200 °C maximum is intended for short-term peak applications. This distinction is standard for laboratory furnaces to balance process flexibility with component longevity.
What are the power supply requirements for the SF-1200-1I furnace and how do they affect laboratory installation?
The furnace requires a single-phase AC 220V, 50/60Hz supply with a power rating of 3 kW. This common laboratory voltage simplifies integration into standard electrical infrastructure, but users must verify circuit capacity, grounding, and local electrical codes before installation to avoid operational interruptions.
What critical considerations apply when using the vacuum or flowing-gas treatment capability with this 1200 °C hot-press furnace?
The furnace supports both vacuum and flowing-gas environments, but the specific gas type, vacuum level, and pressure control must be confirmed during quotation to match the intended process. Additionally, the configuration focus on Φ100 mm and 40 T means that sample size and pressing force must be compatible with the gas flow path and sealing system to maintain process integrity.
This small vacuum hot-press furnace combines a compact 100 mm diameter chamber with 40-ton pressing force for sintering and annealing under vacuum or flowing gas up to 1200 °C (continuous operation at 1150 °C). The limited heating rate and specific 220 V/3 kW power requirement are key operational constraints for labs with rapid thermal cycling or non-standard electrical infrastructure.
Positive
- Compact chamber with high pressing force: The 100 mm diameter chamber paired with 40 T pressing capability enables high-pressure densification of small samples, ideal for laboratory-scale sintering and material development.
- Vacuum and flowing-gas compatibility: Supports both vacuum and controlled-atmosphere processing, allowing versatile thermal treatments including calcination, annealing, and sintering under inert or reducing conditions.
Trade-offs
- Limited heating rate: Maximum heating rate of 10 °C/min constrains rapid thermal cycling, extending total process time for temperature-sensitive protocols or high-throughput workflows.
- Specific power and temperature limits: Requires a 220 V, 3 kW supply and is rated for continuous operation at 1150 °C (not 1200 °C), which may necessitate dedicated electrical infrastructure and reduce headroom for prolonged high-temperature runs.
