Product Introduction
Heat Treatment Bell Furnaces are widely used for batch thermal treatment of metal coils, sheets, strips and wire components. The equipment features a split structural design, with a movable heating bell and independent stationary furnace base. This separated layout simplifies loading and unloading operations for large, bulky workpieces, and supports flexible switching between heating and cooling stages.
This Heat Treatment Bell Furnace supports two heating options: electric heating and gas-fired heating. Controlled atmosphere setups can be integrated for workpieces requiring reduced-oxidation heating, preserving metal surface quality during thermal processing. Core equipment parameters including furnace body size, base load capacity, heating system configuration and cooling modes can be adjusted to match actual workpiece specifications and on-site production conditions.
The furnace performs core thermal treatments for ferrous metals. It handles annealing and stress relieving for coiled and strip workpieces, as well as normalizing and aging for various structural metal components. With several furnace bases available, the heating bell can be moved to another station after one heating cycle, allowing loading and cooling operations to continue at the other bases.
Main Components
Bell-type heating cover: Integral rigid frame structure with multi-layer refractory and thermal insulation lining. It resists long-term high-temperature operation and minimizes internal heat loss during soaking cycles.
Heat Treatment Bell Furnace base and workpiece support structure: Reinforced load-bearing base matched with customized workpiece brackets. It ensures stable placement of heavy coil and strip workpieces while achieving even bottom heating.
Heating system: Configurable with electric heating elements or gas burner assemblies. The distributed heating layout delivers uniform heat radiation and adapts to different process temperature requirements.
Atmosphere and circulation system: Consists of protective gas pipelines and circulating fan units. It allows protective gas to be introduced, replaced and circulated, supporting controlled atmosphere heat treatment to reduce surface oxidation.
Temperature measurement and control system: A multi-point thermocouple system, PID controller and electrical control cabinet monitor furnace temperature and regulate heating output throughout the process.
Lifting and cooling device: Equipped with a dedicated lifting mechanism for stable bell cover movement. Matched staged cooling structures support flexible cooling rate adjustment for different workpieces.
Equipment Features
Alternating multi-base operation:
One heating bell can serve multiple independent furnace bases. While one base is in the heating stage, other stations can complete workpiece loading and cooling work, greatly improving equipment utilization rate.
Dual Heating System Options:
The heating system can be selected according to the available energy source, required process temperature and production conditions. Electric and gas-fired layouts are both configurable to fit on-site utility conditions and production needs.
Even Chamber Heating:
Assisted by internal circulating fans, heat spreads evenly inside the closed cavity. It helps reduce local temperature differences and provides consistent heating for thick coils and stacked workpieces.
Controlled Atmosphere Processing:
Optional protective atmosphere configurations help isolate the workpieces from air and combustion gases. This method preserves smooth surface finish for high-precision metal strips and coils throughout heating.
Reliable Long-Cycle Operation:
Optimized insulation structure and reasonable heating layout adapt to extended soaking processes. The whole equipment runs steadily during repeated batch production and minimizes heat loss.
Customized Furnace Configuration:
Core specifications including furnace dimension, load capacity, heating layout and cooling mode can be adjusted to match workpiece types and workshop layout.
Applications
This Heat Treatment Bell Furnace is widely applied in metal coil processing, wire manufacturing and mechanical parts heat treatment scenarios. It mainly handles thermal processing for carbon steel, alloy steel and stainless steel materials, covering coils, strips, sheets, wires, shafts and other metal components.
The movable bell structure makes loading and unloading easier for large, heavy workpieces and is well suited to repetitive batch heat treatment.
