Metal Annealing Radiant Burner

When Huashuo Factory was manufacturing this Metal Annealing Radiant Burner, the entire body was designed with a reinforced frame structure, which was compatible with mainstream annealing furnaces such as continuous belt annealing furnaces, trolley furnaces, and box-type annealing furnaces. It was equipped with a segmented intelligent temperature control module, allowing for the setting of complete annealing curves including stepwise heating, constant temperature insulation, and slow cooling. This was suitable for stress relief processes of different material workpieces such as steel, aluminum alloy, copper alloy, and precision fasteners.

Details

The far-infrared penetrating heating method enables the entire workpiece to be heated simultaneously, slowly eliminating internal residual stress, improving the metal grain structure, reducing the risk of subsequent processing deformation and cracking, and ensuring uniform hardness of the entire batch of workpieces and meeting the standard for dimensional stability. The combustion system adopts a premixed air supply structure to ensure complete combustion, reduce ineffective heat loss, and be suitable for the slow process production mode of long-term constant temperature annealing, balancing the quality of heat treatment and long-term energy consumption control. The overall layout of the equipment is convenient for inspection and maintenance, can seamlessly connect with the automated heat treatment production line, and is suitable for standardized annealing production of large quantities of hardware, profiles, and automotive parts.

Advantages

1. The infrared radiation penetration heating method ensures uniform heating both inside and outside the metal workpiece, resulting in consistent stress distribution of the material after annealing, and higher qualification rate of the finished products.
2. The temperature control range is wide and the temperature rise is gradual, which can precisely match different metal annealing processes, and is less likely to cause over-burning or uneven hardness issues.
3. The gas combustion is thorough with low heat loss. Compared to traditional hot air furnaces, it has lower energy consumption and can effectively reduce gas costs for continuous heat treatment.

Parameters

The natural gas consumption ranges from 2.8 to 4 cubic meters per hour. After the temperature stabilizes, the consumption drops to approximately 2 cubic meters per hour, and the unit supports 24-hour continuous operation.

Usage Notes

1. Before the initial installation and commissioning of the Metal Annealing Radiant Burner, complete the gas pipeline tightness test and exhaust replacement, strictly follow the ignition process of the gas equipment, and strictly prohibit direct forced ignition to prevent gas accumulation hazards.

2. When setting the annealing temperature control curve, follow the corresponding metal material process specifications, control the heating rate, insulation duration and cooling rate, and avoid rapid heating causing local thermal stress rebound.

3. Regularly inspect the surface condition of the aluminized radiation tubes to prevent hard objects from hitting, long-term dust adhesion, and prevent attenuation of radiation efficiency and local overheating problems, ensuring the uniform and stable heat field of the furnace chamber.

4. Monitor the gas supply pressure and gas quality, maintain stable gas supply parameters, and avoid temperature drift and abnormal combustion caused by pressure fluctuations, affecting the consistency of annealing quality.

5. During equipment operation, maintain the ventilation environment of the workshop, regularly check the exhaust and tail gas emission systems to ensure normal combustion conditions and comply with environmental protection emission requirements.

6. During equipment maintenance and cleaning operations, it is necessary to first close the main gas valve, cut off the power supply, wait for the furnace body and radiation tubes to fully cool down before operating, to prevent scalding and gas risks caused by high temperatures.

7. When the equipment is stored for a long time, take measures to protect the pipelines and prevent dust, and complete leak detection and no-load test run before restarting to confirm that the temperature control and combustion systems are operating normally before putting it back into production.

8. Calibrate the temperature control instruments and sensors according to the equipment manual on a regular basis to ensure the full cycle temperature accuracy and avoid parameter deviations affecting the metal annealing performance.

Working principle

Natural gas and electricity are connected, the burner emits flames, the flames burn within the pipeline, and the heat radiates outward from the heat radiation pipeline, thus evenly distributing the heat in the heating chamber. Flameless heating will significantly reduce the damage to the workpiece and also maintain the cleanliness of the heating chamber.
