In the realm of metal processing, the quest for superior quality and efficiency has led to the development of advanced heat treatment equipment. In this blog post, as a high quality annealing furnace supplier, YIFA will share with you the features of nitrogen protected annealing furnace for sale.
The RJ2-500-8 Nitrogen Protected Annealing Furnace is a well-type vacuum atmosphere spheroidizing furnace that stands out for its robust construction and advanced technical specifications. With an effective working size of Ø 2500 × 2800mm, this furnace is designed to handle large-scale metal annealing tasks with precision.
Material and Construction:
The furnace body is constructed from 321 stainless steel, a material chosen for its excellent heat resistance and corrosion properties, ensuring the longevity and reliability of the equipment. This material is crucial for maintaining the integrity of the furnace during the high-temperature annealing process.
Loading and Capacity:
The loading system is designed to accommodate bobbin 800, with a size of φ800×585mm, capable of collecting 800 to 1000kg per bobbin. The furnace can load up to 20pcs of bobbin 800, arranged in a 5pcs per layer configuration, with a total of 4 layers, allowing for a maximum loading weight of 16 to 20 tons.
Temperature and Power:
The furnace operates at a rated temperature of 950℃, with a normal operating temperature range of 730 to 850℃. This wide temperature range caters to various annealing requirements of different metal materials. The power supply can be either electrical or natural gas, offering flexibility to users based on their energy infrastructure.
Operation Process:
The operation of the RJ2-500-8 is a testament to its advanced design. After vacuuming the furnace liner, nitrogen with a purity of 99.99% is introduced, ensuring an inert atmosphere that protects the metal from oxidation. The process involves loading the workpiece, creating a vacuum, and then filling the furnace with nitrogen to a pressure of 0.25Mpa. An automatic alarm system is in place to prevent overpressure, ensuring safety and process control.
Heating and Cooling:
The heating process is meticulously controlled, with a set temperature range of 730-850 degrees, requiring approximately 3.5 hours for heating and about 4 hours for maintaining a constant temperature. The furnace automatically cuts off power and initiates cooling, which can be facilitated by air or nitrogen, enhancing the efficiency of the cooling process.
Safety and Efficiency:
Safety is paramount in the design of the RJ2-500-8. The furnace is equipped with an overpressure alarm system and a safety explosion-proof pointer to prevent damage to the explosion-proof valve. The internal fan circulation, powered by a sealed motor, ensures uniform heat distribution within the furnace, contributing to the efficiency of the annealing process.
Conclusion:
The Nitrogen Protected Annealing Furnace from YIFA is a powerhouse in the field of metal heat treatment. Its features, such as the use of high-purity nitrogen, robust stainless steel construction, and precise temperature control, make it an ideal choice for industries requiring high-quality annealing processes.
