Dual Chamber Heat Treat Furnace

Dual Chamber Heat Treat Furnace | Industrial Bogie Hearth Design for Precision Thermal Processing

Enterprise-grade Dual Chamber Heat Treat Furnace solutions come from JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD. We build them for stress relief annealing and precise thermal processing. The gas-fired bogie hearth setup runs at 550℃ as standard. Turn it up and it reaches 950℃. After one hour of heat preservation, temperature uniformity stays within ±8℃. Every unit is made in our 20,000㎡ plant, which holds 80 million yuan in fixed assets. The 350mm refractory fiber lining comes as standard. So do switchable pulse or regenerative combustion systems. Heating rates adjust from 50-200℃/h with the furnace fully loaded. Our team of 100+ professionals checks each unit against national quality standards before it ships.

Why Choose Our Heat Treatment Solution?

The bogie hearth design avoids the logistical disadvantages of moving large work parts from one unit to another. The self-propelled chain-driven bogie system moves at 5-7m/min letting your production team to enjoy the benefits of a system that allows the full furnace chamber to leave for easy loading.

Multi-zone independent temperature control keeps out the usual metallurgical flaws. Uneven hardness distribution is one. Surface oxidation is another. For the control system we use a semi-automatic design. It runs on an imported PID intelligent instrument and Omron PLC technology. Your heat treatment cycle then holds to ±2℃.

The multi-layer composite lightweight fibre construction sets new milestones in energy efficiency. The temperature rise of the furnace shell is less than 45℃ on top and 40℃ on side walls even at 950℃ operations. The energy consumption is reduced by 25-42% compared with the conventional heating furnaces.

Technical Specifications

Core Performance Advantages

Precision Temperature Management

Your heat treatment processes demand consistency. Our multi-zone independent PID control architecture maintains temperature variation within ±5℃ across the entire heating zone. This precision eliminates hardness inconsistencies and dimensional distortion, directly improving your product qualification rates.

Optimized Energy Performance

The closed heat preservation structure combines ultra-low surface heat loss materials with minimal radiation leakage design. Your facility benefits from reduced operational costs while maintaining consistent thermal processing capability throughout extended production cycles.

Flexible Operational Configuration

Two combustion modes can be switched to suit changing production demands. Maybe you need fast heating from pulse combustion. Maybe you want steady efficiency from the regenerative systems. Either way, the Dual Chamber Heat Treat Furnace adapts to your process requirements. No equipment modification is needed.

Industrial Applications of the Dual Chamber Heat Treat Furnace

This thermal processing system is designed for firms needing regulated stress relief annealing for essential components. Our technologies are used in automotive tooling processes for dimensional stabilisation of precision dies and moulds.

Manufacturers of heavy machinery process huge structural parts and require homogeneous heat dispersion. They use customisable dimensions of the chamber. Full bogie exit capability allows handling of big workpieces difficult to fit in standard furnace designs.

High-carbon steels are common in metal fabrication shops. For those facilities, the Dual Chamber Heat Treat Furnace brings real benefits. Heating rates stay under control and temperature control is accurate. Thermal shock is avoided that way, and the metal keeps its metallurgical integrity through the hardening and tempering cycles.

FAQ

Q: What makes the bogie hearth design advantageous for heat treatment?

A: The self-propelled bogie system allows complete furnace chamber exit, simplifying loading and unloading of heavy workpieces. This design reduces handling time and minimizes risk of component damage during transfer operations compared to fixed-hearth configurations.

Q: Can the furnace accommodate custom temperature profiles?

A: Yes. Control zones get set up to match the heat treatment processes you run. Under full loading the heating rate can be adjusted from 50-200℃/h. That gives you room to work with different metallurgical requirements and workpiece geometries.

Q: How does the combustion system affect operational efficiency?

A: Fuel use gets tuned to what production actually needs, thanks to two combustion options: switchable pulse and regenerative. Batch work calls for fast temperature changes, and pulse mode covers that. Run the line nonstop and regenerative combustion keeps thermal efficiency as high as it goes.

Q: What customization options are available?

A: Chamber size, load capacity, temperature zones, and control settings all match your plant's needs. Our engineers work straight from your specs. They design solutions that fit your production workflow and the space you have.

Q: How do large chambers keep the temperature even?

A: Exhaust outlets sit at the top and side walls of the furnace. Multi-zone burner arrangements work with that placement to create controlled circulation patterns. The 350mm refractory fiber lining provides thermal mass stability. Even during loading cycles, heat stays uniform.
