PLC control regenerative burning system for aluminum melting furnace
Regenerative combustion system is automatic operated by PLC, a multicolour touch screen displays aluminium temperature, furnace chamber temperature & regenerative bed air exhaustion temperature digitally.
Temperature of the flue gas exhausted through regenerative burner is lower than 200℃, flue gas which is less than 10% is exhausted from the bypass flue which is for furnace pressure controlling, the sum discharge temperature is lower than 250℃.
Ignites with natural gas.
Compressive air pressure is 4-6kg/cm2, consumption is 35m3/min.
Main power supply is 380V, 50Hz.
FAQ
1. What are the key points of daily inspection?
Temperature/furnace pressure, gas pressure/combustion status, furnace lining/sealing, degassing system, cooling water.
2. What is the regular maintenance cycle?
Daily: Clean the slag from the furnace mouth/flow channel; inspect the burner, ignition system, and seals.
Weekly: verify thermocouples/temperature control instruments; clean the scale in the water gap of the crystallizer; check the integrity of the filter plate.
Monthly: Conduct a comprehensive inspection of the lining thickness/cracks; calibrate the casting speed and traction synchronization; replace aged sealing rings/gaskets.
Every year: overhaul the furnace body (repair/reline the furnace lining); conduct a comprehensive inspection and maintenance of the casting machinery and electronic control system.
3. Safety precautions?
High temperature protection: Wear high temperature resistant clothing, protective face masks, and heat-insulating gloves to avoid burns.
Explosion protection: Leakage is strictly prohibited in gas furnaces, and regular leak detection is required; moist materials are prohibited inside the furnace to prevent explosions caused by water encountering aluminum liquid.
Emergency response: Equip with dry powder fire extinguishers and dry sand.
