Heat Treatment Gas Furnace

High-Performance Heat Treatment Gas Furnace | Bogie Hearth Design for Precision Thermal Processing

JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD makes advanced industrial heating equipment. Its production site covers 20,000㎡, and fixed assets exceed 80 million yuan. The Heat Treatment Gas Furnace uses a bogie hearth setup. It is built for stress relief annealing and for work where temperature is critical. The working temperature can be customized from standard 550℃ up to 950℃. After one hour of heat preservation, temperature uniformity stays within ±8℃. Control precision is ≤±2℃. A 350 mm refractory fiber lining gives strong thermal insulation. Consistent metallurgical results across your entire workload come from the multi-zone PID control system.

What Makes Our Gas-Fired Heat Treatment Solution Different?

When your operation requires reproducible results in thermal processing, precision is what matters. Our gas powered bogie hearth furnace offers the industry a solution to typical problems with modern combustion technology and intelligent temperature control.

The switchable pulse combustion system is high-fire and low-fire mode. The versatility lets you fine-tune the energy input to your process needs. Fuel waste is reduced and heating rates of 50–200℃/h are maintained even with full workpiece loading.

Temperature control zones are set up for your particular heat treatment method. You may work with massive castings or complex assemblies. The multi-zone layout sends even heat to every area of your job. Shell temperature rise stays limited. At a maximum 950℃ working temperature, the furnace top is ≤45℃ and side walls are ≤40℃. This protects your plant environment and operator safety.

The bogie arrangement allows a remarkable ease of loading. Workpieces are loaded on the moveable surface of the hearth. The hearth is moved with the help of a self-propelled chain drive arrangement at 5-7 m/min. The bogie may be completely withdrawn from the furnace chamber, providing you total access for loading and unloading operations. The electric lifting boiler door adopts a wedge locking structure with a speed of 4–6 m/min, which ensures reliable sealing during thermal cycles.

Core Performance Advantages

Precise Multi-Zone Temperature Management

The imported PID intelligent instrument system works with Omron PLC to create independent temperature control zones for Heat Treatment Gas Furnace. This architecture eliminates temperature variation that causes inconsistent hardness, warping, or oxidation defects. Your components emerge with uniform metallurgical properties across the entire batch.

Strong Energy Efficiency Design

Multi-layer composite lightweight fiber lining creates an ultra-efficient thermal barrier. The closed heat preservation structure minimizes radiation losses. Compared to conventional heating furnaces, you'll experience energy consumption reduction of 25%–55%, significantly lowering your operating costs while meeting environmental standards.

Flexible Combustion Configuration

Choose pulse combustion for fast heating cycles. For long processes, choose regenerative combustion to get maximum Heat Treatment Gas Furnace fuel efficiency. Both systems are built for complete combustion with low emissions. That helps you meet environmental compliance goals.

Heat Treatment Gas Furnace FAQ

Q: What temperature uniformity can I expect for large workloads?

A: After an hour of heat preservation, the product holds temperature deviation within ±8℃. Multi-zone control and planned heat circulation make that happen. On critical runs, calibration and zone configuration adjustments can bring deviation down to ±1℃.

Q: How does the bogie system improve production efficiency?

A: With the bogie fully extended, your operators load workpieces outside the furnace chamber. Batches no longer wait on each other, so downtime between runs drops away. The chain-driven system moves smoothly and reliably at 5–7 m/min. It stays in step with your production schedule.

Q: Can the furnace be built to fit my own application?

A: Yes. Chamber dimensions can change to suit your parts. Loading capacity can change too. We set temperature control zones and exhaust configurations around your workpiece geometry and heat treatment process needs. Our engineers work side by side with you on the design.

Q: What control choices let me connect it to systems I already run?

A: The semi-automatic control system uses imported PID instruments and Omron PLC, which support standard industrial communication protocols. You can integrate the furnace into your facility management system for data logging and remote monitoring. Manual operation mode provides backup control capability.

Q: How quickly can the furnace reach operating temperature?

A: Heating rates are adjustable from 50–200℃/h depending on workload mass and material properties. The 350 mm fiber lining reduces thermal mass, enabling faster temperature ramp-up compared to brick-lined furnaces while protecting against thermal shock.
