AI Technical Summary
Existing precast briquette heating furnaces suffer from problems such as large starting current surges, poor power supply stability, and low temperature control accuracy, leading to production interruptions and low heating efficiency.
A soft-start power supply structure using a pre-magnetized transformer and sequential relays, combined with an adaptive furnace temperature control method, achieves safe and stable power supply and precise temperature control for the heating furnace through real-time temperature acquisition, dynamic tuning of PID parameters, and steady-state compensation.
It effectively reduces starting current, improves the stability and safety of the power supply system, enhances the accuracy of temperature control and heating efficiency, and ensures production continuity and product quality.
