Dual Chamber Heat Treat Furnace - Advanced Industrial Bogie Hearth Solution for Precision Thermal Processing
JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD builds enterprise-grade Dual Chamber Heat Treat furnaces. These units are made for precision thermal processing. More than 100 professionals work at the company, and the production facility covers 20,000㎡. Working temperatures on our gas-fired bogie hearth furnaces can be set from 550℃ to 950℃. Temperature uniformity holds within ±8℃. Control precision comes in at ≤±2℃. Each system ships with a 350mm refractory fiber lining and multi-zone independent PID control. Energy consumption falls by up to 49%. Heat treatment quality stays consistent for stress relief annealing and other advanced thermal work.

What Makes Our treatment System Different?
The design of our bogie hearth furnace is smart, and it takes on the thermal processing problems that really matter. Loading capacity can be configured to your needs. Chamber dimensions are customisable too, so they fit your production setup.
A tough 350mm refractory fibre lining sits inside the furnace and keeps thermal insulation strong. Surface heat loss drops because of this multi-layer composite structure. That same structure creates a closed preservation environment. For your facility, the result is far lower operating costs.
Temperature control zones are set to match the heat treatment technique you run. The combustion system switches between pulse combustion with high and low fire settings and regenerative combustion modes. That flexibility lets you raise fuel efficiency to fit what the workload needs.

Core Performance Advantages
Precise Multi-Zone Temperature Control
Your thermal processing needs accuracy. Our multi-zone independent PID control system keeps temperature uniform to within ±5℃ across the whole heating chamber. Uneven hardness is one common defect this precision gets rid of. Workpiece deformation goes away too. So does excess oxidation. Every batch gets the same heat treatment quality.
Strong Energy Efficiency
The Dual Chamber Heat Treat design incorporates advanced thermal management. Multi-layer composite lightweight fiber lining delivers ultra-low surface heat loss. The closed heat preservation structure minimizes radiation losses. You'll experience energy savings of 25% to 49% compared to conventional heating furnaces.
Flexible Operation Modes
The semi-automatic control system uses imported PID intelligent instruments with Omron PLC integration. Manual mode remains available when you need direct control. The furnace door lifts at 6 m/min with wedge locking structure and electric hoist drive. Your operators can fully move the bogie outside the chamber for convenient loading.

Intelligent Combustion and Exhaust Management
Switchable combustion system adjusts to your process needs. High/low pulse combustion allows fast temperature control. Extended operations are performed in regenerative combustion mode for maximum fuel efficiency.
Strategic exhaust openings at the top and side walls of the furnace provide adequate ventilation. The chimney is at least 2 meters higher than the top of your factory so the exhaust is dispersed safely.

Before shipment, each unit of goods is checked by the quality inspection department according to national standards.
Mechanical engineers, automatic control experts, and quality inspection professionals make up our multidisciplinary team. Their knowledge makes sure your Dual Chamber Heat Treat furnace fits right into the manufacturing systems you already have.

FAQ
Q: How hot can this furnace get?
A: Normal running heat is 550℃. You can turn it up to 950℃ if you need to. That covers stress relief annealing and most other thermal processing jobs.
Q: How uniform is the temperature distribution?
A: After 1 hour of heat preservation, the heating zone maintains temperature deviation of ≤±8℃ to ±1℃. Control precision remains at ≤±2℃ throughout operation.
Q: Can the chamber size be customized?
A: Yes. The chamber size and the load capacity both get built to your own specs. Our engineers work out a design that suits how your line actually runs.
Q: What kind of control system comes with it?
A: The furnace features semi-automatic control through imported PID intelligent instruments and Omron PLC. Manual operation mode is available for specialized processes.
Q: How does the bogie system work?
A: Chain drive runs the self-propelled bogie. Speed is 5–7 m/min. Loading and unloading is easy because the unit can move right out of the furnace chamber.
Q: How much maintenance does the furnace need?
A: Checks we run on a regular schedule cover three areas. First, the condition of the refractory lining. Second, the parts that make up the combustion system. Third, calibration of the control instruments. Every component we use is checked against national and industrial standards, and our quality management system is what makes that happen.
Q: Is the heating rate adjustable?
A: Yes. With a full load of workpieces inside, the heating rate can be set anywhere from 50 to 200℃/h. Different materials need different rates, and production schedules vary too. This range covers both.
Q: What fuel does the system use?
A: Natural gas feeds the furnace. Its calorific value is 8500 Kcal/Nm³. At different temperature ranges, the combustion system keeps fuel use as low as it can.
