Description

Technical Field

[0001] This utility model belongs to the field of industrial automation technology, specifically a medium-frequency electric furnace water circulation monitoring and alarm device. Background Technology

[0002] Medium-frequency electric furnaces are based on Faraday's law of electromagnetic induction. They generate a magnetic field through medium-frequency alternating current, which induces eddy currents in the metal workpiece to achieve heating. They have the advantages of high efficiency, precision, and high degree of automation. In the mid-21st century, their application was limited due to the limitations of generator-type medium-frequency power supplies. However, with the continuous innovation of thyristor and power electronics technologies in the last century, solid-state medium-frequency power supplies have emerged, significantly improving the power and efficiency of electric furnaces. This has promoted the widespread application of medium-frequency electric furnaces in the fields of metallurgy and machinery manufacturing, making them a key piece of equipment for modern industrial metal smelting, heating, and heat treatment.

[0003] In high-temperature operations such as metal smelting and heat treatment, medium-frequency electric furnaces require a water circulation system to maintain stable equipment temperature. The safe operation of this system directly affects production efficiency and equipment lifespan. Currently, water circulation monitoring and alarm devices for medium-frequency electric furnaces generally integrate multi-parameter sensors, enabling real-time monitoring of key indicators such as water flow, temperature, and pressure. They respond quickly to anomalies through audible and visual alarms and electrical interlocks. Some systems also support remote data transmission and fault diagnosis, and alarm thresholds can be flexibly set, significantly improving the safety and reliability of the furnace cooling system. However, existing technologies have significant shortcomings in automatic water injection. Most systems can only alarm and cut off the power supply, lacking an active water replenishment mechanism. In the event of pipe blockage, water pump failure, or water supply interruption, manual intervention is required to operate the water replenishment valve or start the backup pump. The response delay can easily lead to overheating and damage to the electric furnace due to water shortage. Utility Model Content
