AI Technical Summary

Technical Problem

Existing RH furnaces require the gas seal valve to be opened when adding aluminum to prevent high-temperature flue gas from escaping. However, this can easily burn out the external mechanism due to high temperatures, and workers may forget to open the gas seal valve, leading to accidents.

Method used

An automatic control mechanism for the gas sealing valve of an aluminum hopper in an RH furnace was designed, including a temperature sensor and an actuator. By monitoring the internal temperature of the hopper, the valve body is automatically controlled to open and close, avoiding misoperation. When aluminum is added, inert gas is blown out to create a positive pressure environment and prevent air from entering.

Benefits of technology

It effectively prevents high-temperature flue gas from escaping, avoids the burning of external components, reduces the risk of human error, and ensures the safe operation of the RH furnace.
