1-6kg Infrared Thermometer Platinum Melting Furnace

【Infrared Thermometer Platinum Melting Furnace Structure】
The platinum melting machine integrates precision engineering with advanced temperature control systems. Key structural components include: melting chamber (quartz crucible, induction coil), infrared temperature measurement system (infrared pyrometer, optical lens & signal processor), power & control system (IGBT module, PID temperature controller), cooling & protection system, frame & interface.

【Infrared Thermometer Platinum Melting Furnace Work Principle】
The platinum melting machine uses electromagnetic induction heating, combined with infrared temperature feedback, for precise and efficient metal processing. When powered on, the machine’s IGBT module converts standard AC into high-frequency alternating current, which flows through a tightly wound copper induction coil, generating a strong electromagnetic field. This field induces eddy currents within the platinum metal placed inside the quartz crucible, causing rapid resistive heating without direct contact. Simultaneously, an infrared pyrometer continuously monitors the metal’s surface temperature by measuring emitted thermal radiation, transmitting real-time data to a PID controller. The controller dynamically adjusts power output to maintain the exact set temperature, preventing overheating or instability. Cooling is managed via a water-circulation system that prevents critical components (e.g., coil, IGBT) from excessive heat buildup, while integrated safeguards (over-current, overheating, and water shortage protection) ensure fail-safe operation. This closed-loop system guarantees fast, uniform melting.
