High-Performance Gas-Fired Treatment Furnace for Stress Relief Annealing and Precision Heat Treatment Solutions
JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD specializes in advanced Treatment Furnace systems engineered for industrial heat treatment applications. Our gas-fired bogie hearth furnace operates at standard temperatures of 550℃ with adjustability up to 950℃, featuring exceptional temperature uniformity of ±8℃ after one-hour heat preservation. With 350mm refractory fiber lining and multi-zone PID control systems, this product delivers temperature control precision within ±2℃. Backed by our 20,000㎡ production facility, 80 million yuan in fixed assets, and over 100 specialized engineers, we provide enterprise-grade thermal processing equipment that meets stringent industrial standards for stress relief annealing and precision metallurgical operations.
What Makes Our furnace Your Optimal Heat Treatment Solution?
Our solution solves typical manufacturing problems such as material brittleness, residual internal tensions and non-uniform surface hardness. This precision constructed system offers the controlled heating and cooling cycles required for the annealing, tempering and stress relief procedures.
The gas fired bogie hearth design provides full workpiece movement. Your materials are loaded onto the movable bogie surface which runs at 5-7 meters per minute with full furnace extraction capabilities. The arrangement allows for ease of loading and unloading, and maintains thermal integrity during the treatment process.
The temperature is controlled in several distinct zones, which provides even distribution of heat. The adjustable heating rate of 50 to 200℃/h, under the full loaded situation, meets various process needs without sacrificing the quality consistency.

Core Advantages That Enhance Your Production Efficiency
Precision Multi-Zone Temperature Control
Thermal gradients in your workpieces get removed by multi-zone PID temperature regulation that runs each zone on its own. Temperature variance stays within +/- 5℃. That avoids hardness variations, dimensional distortions and oxidation flaws, all of which harm the integrity of the component.
Energy-Efficient Thermal Management
A multi-layer composite fibre liner, light in weight, cuts the heat that escapes from the surface. Heat loss through thermal radiation drops with this closed insulation design. Energy consumption falls by 25-60% next to traditional heating furnaces, and ideal operating temperatures still hold.
Technology of Combustion Flexibility
Your furnace can run on pulse combustion with high/low fire modes. It can also switch to regenerative combustion, based on what the process needs. Either way, fuel efficiency improves and accurate atmospheric conditions hold through the treatment cycles.
Applications and Process Capabilities
This treatment system works well for stress relief annealing jobs. Heat is controlled, so leftover stress from welding drops away. Stress from casting and machining goes too. Tight temperature control keeps the microstructure safe. Ductility returns to the material.
Chamber dimensions can be customized. That means parts of different sizes fit inside. Small precision parts are no problem. Large structural elements fit too. The bogie hearth setup gives you flexible loading choices. Work moves faster with fewer holdups.
Burning natural gas gives off clean heat that stays steady. No contaminants get in to spoil surface quality. Outlets sit at the top of the Treatment Furnace. Some are on the side walls too. That exhaust system keeps air moving properly. Air conditions stay right through every treatment process.
Treatment Furnace Quality Assurance and Control Standards
Before shipment, every furnace goes through a check by our quality inspection department. That check follows national and industrial standards. Temperature uniformity surveys show heat distribution meets the specification requirements. System accuracy tests confirm how control instruments and thermocouples work together.
Imported PID intelligent instruments and an Omron PLC handle automation reliably. They also let you take manual control when needed. With these two modes, you can work through commissioning, maintenance, or specialized process development. Safety protocols stay in place the whole time.
Wedge locking structures hold the electric hoist-driven furnace door shut tight while it runs. Door lift speed is 4 to 6 meters per minute. That speed allows fast cycle changes. Thermal stability and Treatment Furnace worker safety are not put at risk.
FAQ
Q: What temperature range can this product achieve?
A: Normal running temperature sits at 550℃. You can turn it all the way up to 950℃. That spread covers stress relief annealing, normalizing, and tempering for ferrous and non-ferrous alloys.
Q: How does the bogie hearth design benefit my operations?
A: The bogie runs on its own chain drive and pulls the whole load out of the furnace. Loading and unloading get a lot easier that way. Compared with a fixed hearth setup, it cuts handling time and makes the workplace safer.
Q: What level of temperature uniformity can I expect?
A: Hold the heat for one hour and the temperature across the heating zone stays within ±8℃. Control precision adds another ±2℃. Every workpiece surface ends up with the same metallurgical result.
Q: Can this furnace be built to suit a particular application?
A: Yes. Chamber dimensions, loading capacity, temperature control zones, and combustion systems are configured based on your heat treatment process requirements and production volume needs.
Q: What kind of fuel does the system need?
A: Natural gas feeds the furnace, and its calorific value is 8500 Kcal/Nm³. Fuel use stays low, thanks to the combustion system. The atmosphere inside is also held at a precise level through every treatment cycle.
Q: In what ways does the insulation cut running costs?
A: The 350mm refractory fiber lining with multi-layer composite construction minimizes heat loss through furnace walls. This design reduces energy consumption by 25–60% while maintaining shell temperature rises below 45℃ on the top and 40℃ on side walls.
