2. The Leakage Alarm System: Ensuring Safety and Reliability

Why the Leakage Detection System is Essential

The leakage detection system integrated into the Rongke furnace represents a critical safety feature, designed to ensure the safe and effective operation of the system. The principle behind its operation is both straightforward and highly effective: when molten iron begins to seep through the furnace lining, it makes contact with a current detection electrode, triggering an alarm. Should the leakage reach the coil, the system will issue a second alert, precisely pinpointing the location of the issue.

The real-time detection capabilities of this system are essential for preventing minor problems from escalating into significant hazards, such as fires or extensive equipment damage. By providing early warning signals, the leakage detection system allows maintenance teams to address potential issues before they lead to costly downtime or accidents.

Grounding Alarm Detection: A Layered Approach to Safety

The grounding alarm detection system operates in a manner similar to the leakage detection system but focuses on different aspects of furnace safety. When molten iron penetrates to within 2cm of the coil, the system detects an increase in leakage current directed to the ground. Should the conductivity of the coolant exceed a predefined threshold, the system triggers an alarm.

This multi-tiered safety framework ensures that any irregularity in the furnace’s operation is detected at the earliest possible stage, thus significantly reducing the likelihood of accidents. The combination of these sophisticated alarm systems further underscores Guangdong Rongke’s dedication to providing furnaces that are both safe for operators and reliable for production.
