Targeting the heat treatment needs of large workpieces, the high-temperature trolley-type electric heating furnace delivered this time utilizes electric heating. The equipment mainly consists of the furnace body, furnace door lifting mechanism, trolley traveling mechanism, temperature control system, and electrical control system.
The equipment's maximum operating temperature can reach 1200℃. It features a large heating space, precise temperature control, strong loading capacity, and stable operation, meeting the heat treatment production needs of large metal workpieces and batch products.
The effective heating dimensions of this equipment are 1600×4000×1200mm, with a maximum furnace capacity of 10 tons/furnace. The trolley adopts an electric traveling structure, facilitating workpiece loading, unloading, and transfer, improving equipment utilization efficiency.
For high-temperature working environments, the furnace body adopts a reasonable insulation and structural design to reduce heat loss and control the surface temperature rise of the furnace body. During normal operation, the surface temperature rise of the furnace body is ≤50℃.
Precise Temperature Control to Meet Heat Treatment Process Requirements
The equipment operates within a temperature range of 600℃ to 1200℃, employing a multi-zone temperature control system that allows for zoned temperature adjustment within the furnace according to different heat treatment processes.
The furnace temperature uniformity (TUS) requirement is **±8℃**, with temperature overshoot ≤8℃. The heating time from room temperature to 1200℃ in an empty furnace is ≤240 minutes, helping to ensure uniform heating of workpieces and high-quality heat treatment.
Simultaneously, the equipment's temperature measurement and calibration are designed according to relevant standards, meeting the latest version of AMS 2750 and HB 5425 specifications.
The equipment is equipped with an independent trolley traveling mechanism, making loading and unloading more convenient. Operators can directly load large workpieces onto the trolley, using it to move them in and out of the furnace to complete the heat treatment process.
The electrical control system is integrated with the temperature control system, enabling centralized management of equipment operating status, furnace temperature, and various control zones, improving equipment automation and production safety.
After manufacturing, the equipment undergoes structural, electrical, temperature control, and operational performance checks according to technical requirements. Key parameters are debugged and verified to ensure the equipment meets design specifications before leaving the factory.
The successful delivery of this high-temperature bogie-type electric heating furnace demonstrates the comprehensive performance of large-scale industrial heat treatment equipment in high-temperature heating, precise temperature control, large workpiece loading, and automated control. It provides stable and reliable equipment support for the customer's subsequent heat treatment production.
