Energy-Saving Gas Aluminum Melting Furnace (Integrated Melting & Holding)

Integrated melting and holding in one unit with flue gas preheating for energy savings · Capacities 1000–8000 kg · PLC controlled

Furnace Overview

This series of furnaces is designed to combine melting and holding functions into a single integrated unit. The concept is tailored to meet the demand for centralized aluminum supply in die-casting and low-pressure casting industries. By integrating both functions, production efficiency and equipment utilization are significantly improved. Molten aluminum, after melting, is transferred through a launder to a ladle for further processing. To further enhance energy efficiency, this furnace adopts a flue gas preheating system that uses waste heat from exhaust gases to preheat combustion air. This technology reduces fuel consumption and improves economic benefits while minimizing environmental impact.

In terms of safety and automation, the furnace is equipped with a PLC control system. Through programmed logic, the combustion system's safety protections are implemented, greatly increasing the level of automation. The PLC continuously monitors furnace operation, detects potential hazards in real time, and ensures safe and reliable performance. By combining flue gas preheating and PLC controls, this series achieves high energy efficiency, enhanced safety, operational stability, user-friendliness, and reduced maintenance costs, delivering higher economic returns and productivity for users.

Safety & Environmental Design

The pool-type gas aluminum melting furnace is designed with safety and environmental protection as priorities. The furnace body is equipped with an over-temperature alarm and automatic fuel cut-off system. When the furnace temperature exceeds the preset safe limit, the system automatically shuts off the fuel supply and triggers an alarm, effectively preventing accidents caused by overheating. Safety guardrails and warning signs are installed around the furnace to ensure operator safety.

On the environmental front, the furnace uses high-efficiency burners combined with an optimized combustion control system to ensure complete fuel combustion, reducing harmful emissions. It meets national and local environmental standards.

• What is the advantage of an integrated melting and holding furnace?
  This design combines both functions in a single unit, saving floor space, reducing heat loss during transfer, and improving energy efficiency. It is ideal for centralized aluminum supply in die-casting and low-pressure casting facilities.
• Is the furnace suitable for continuous operation?
  Yes. The heavy-duty design and robust refractory lining are built for 24/7 continuous operation. The PLC system ensures stable performance and safety under sustained use.
• What safety features are included?
  The furnace is equipped with over-temperature alarm with automatic fuel cut-off, flame monitoring, gas leak detection, and an emergency stop system. Guardrails and warning signs are also installed around the furnace for operator protection.
• How is the furnace maintained?
  Routine maintenance includes checking the burner, cleaning the heat exchanger, inspecting the PLC system, and verifying safety interlocks. The design allows easy access to key components for inspection and servicing.
• Can the furnace be customized for different capacities or fuels?
  Absolutely. We offer customization in furnace size, burner configuration, control system, and fuel type (natural gas, LPG, or other gases) to meet specific production requirements. Please consult our engineering team for tailored solutions.
