대표적인 적용 분야
The SP-25BD is ideal for rapid melting, heat treating, and thermal cycling of metallic materials in research and development laboratories. It supports experiments requiring precise temperature control and inert atmosphere protection, such as alloy development, materials synthesis, and thermal property studies.
구성 및 작동 안내
The system includes a complete alumina refractory assembly but requires a compatible crucible and inert gas supply to protect the graphite crucible and thermocouple during operation. Protective inert gas flow should be maintained below 200 ml/min. The induction coil can be integrated into gloveboxes via a KF40 feedthrough with inert gas supply. A recirculating water chiller is recommended for optimal cooling performance and system longevity. Optional temperature controllers and thermocouples are available to enhance process control. Safety features include automatic shutdown on water pressure loss, overheating, overpower, and water overpressure conditions.
