Product Introduction
The Round Split Bell Type Furnace is designed for batch heat treatment of coils, strip steel, wires and stacked metal parts. It adopts a split structural layout, consisting of a movable furnace bell and a fixed furnace base. Compared with conventional integrated bell furnaces, this split design supports flexible bell lifting and positioning, simplifying the handling of large and bulky workpieces during loading and unloading.
The Round Split Bell Type Furnace is commonly used for atmosphere-protected annealing, tempering and stress relief processes. The circular heating chamber promotes even heat distribution around the workpieces and helps reduce local temperature differences during heating. Chamber dimensions, heating power and atmosphere systems can be configured according to workpiece size, batch weight and production requirements, matching different heat treatment workflows in metal processing.
Working Principle
Workpieces are stacked and fixed on the refractory furnace base following standard loading arrangements. The split furnace bell is lifted and lowered by the drive system to form a fully enclosed circular heating chamber. Before heating, the chamber can be evacuated or filled with protective gas according to process requirements to control the internal atmosphere environment.
Heating components arranged around the chamber generate heat through radiation and convection, helping distribute heat evenly across the workpiece surfaces and surrounding areas. The control system adjusts heating output and atmosphere parameters according to the preset process curve, completing temperature rise, soaking and staged cooling in sequence. Once the heat treatment cycle finishes, the furnace bell is lifted, enabling quick workpiece replacement and continuous batch operation.
Main Components
Circular furnace base: Reinforced base structure with refractory lining, designed for long-term high-temperature operation and stable support of batch-loaded workpieces.
Split furnace bell assembly: Rigid bell shell matched with multi-layer high-temperature insulation lining, which helps reduce heat loss during prolonged soaking cycles.
Circumferential heating system: Heating elements arranged along the circular chamber wall, providing heat radiation around the workpieces inside the chamber.
Lifting and sealing unit: Equipped with hydraulic drive components and mechanical locking structure. Multi-layer sealing design improves chamber tightness and reduces gas leakage during atmosphere-controlled processing.
Atmosphere and vacuum system: Includes protective gas delivery pipelines and vacuumizing devices to support gas replacement and low-oxidation heating environments.
Measurement and control system: Multi-point thermocouples capture real-time temperature data across different zones. The PID programmable cabinet regulates heating parameters and records the full process data.
Safety protection system: Built-in over-temperature protection, pressure relief and fault alarm interlocks support safe operation during long heating cycles.
Features
Uniform circular heating layout:
Heating elements arranged circumferentially around the round chamber deliver balanced heat distribution inside the cavity. This structure lowers temperature deviation and creates stable heating conditions for stacked and coiled metal workpieces.
01
Practical split bell structure:
The separable bell and fixed base design simplifies loading, placement and inspection of large workpieces on the base station, making repetitive batch processing easier to manage.
02
Stable atmosphere environment:
Multi-layer sealing structures and gas replacement components help maintain a stable furnace atmosphere during heat treatment. The sealed chamber and protective gas system help limit surface oxidation and decarburization during annealing.
03
Multi-layer insulation:
The composite insulation lining reduces heat loss during heating and soaking cycles, which is suitable for long-cycle heat treatment processes.
04
Programmable process control:
The control system can store multiple process curves for repeatable batch production. The Round Split Bell Type Furnace runs steadily with routine daily maintenance requirements.
