AI Technical Summary

Technical Problem

During the production process of galvanized aluminum-magnesium products, the furnace nose humidification system will become unstable after the humidification nitrogen is inflowed for a period of time, resulting in fluctuation of the gas dew point in the furnace nose, resulting in color difference in the surface of the strip steel and pit defects.

Method used

Design a device including a furnace nose body, drainage tank, gas heater, humidification tank and nitrogen pipeline. By installing a gas heater behind the humidification water tank, the humidified nitrogen gas is heated to a certain temperature, reducing the probability of condensation water, and installing a drainage tank before the humidification nitrogen gas enters the point. The drainage tank is used to discharge condensation water and discharge remaining nitrogen when it is discontinued, and keeping the humidified nitrogen gas in the nitrogen pipeline in the flow state.

Benefits of technology

By heating and using drainage tanks, the probability of humidifying nitrogen producing condensate is significantly reduced, the operation of the furnace nose humidification system is stabilized, and the poor color difference and defects on the surface of the strip steel are avoided.
