Gas Fired Heat Treatment Furnace

Gas Fired Heat Treatment Furnace | Bogie Hearth Type for Precision Industrial Thermal Processing

JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD makes Gas Fired Heat Treatment Furnace systems for hard industrial jobs. The gas-fired bogie hearth furnace keeps heat even, with a deviation of ≤±8℃. Control accuracy stays at ≤±2℃. Chamber sizes can change to fit the work. Our plant covers 20,000㎡. Fixed assets are 80 million yuan, and over 100 engineers work in specialist roles. The lining is 350mm refractory fiber. Working temperatures can be set from 550℃ to 950℃. Multi-zone PID control systems cut energy use by 25–51% compared with conventional furnaces.

Why Choose Our furnace?

Factory heat treatment often hits hard problems. Our bogie hearth layout is made to solve them. A movable bogie platform lets workers load oversized parts with less effort. No complicated material handling setup is needed.

The pulse combustion system changes between high-fire and low-fire modes as the process needs. Fuel use goes down at different stages. Burner management of this kind adds life to the equipment. Thermal output stays steady.

Your metallurgical requirements decide how the temperature control zones are set up. Maybe you run automotive drivetrain components. Maybe you run aerospace structural parts. Either way, the heating zones can be configured, and they give you even results on complex geometries.

Technical Specifications

Core Advantages That Drive Performance

Precise Multi-Zone Temperature Control

Stay consistent with your heat treating techniques. The multi-zone independent PID system holds the temperature to within ±5℃ across the whole heating chamber. Inconsistent hardness, workpiece distortion and surface oxidation are typical problems. This accuracy helps prevent them. Every zone runs on its own, so you can build custom heat profiles for complex treatment cycles.

Design of Energy-Efficiency Thermal Insulation

A 350mm multi-layer composite fibre liner does a lot of that work. Running costs fall a long way because of it. Heat stays where it belongs inside the closed preservation structure, so less escapes as radiation. Set against conventional furnaces, energy use comes out 25–51% lower. Shell temperature drops to ≤45℃ at the top and ≤40℃ on the walls. That makes the workplace safer. It also lowers the HVAC load in your building.

Flexible Combustion System Choices

Select between switchable pulse combustion and regenerative combustion for your production needs. The pulse system allows for a fast response in batch operations and regenerative combustion maximises fuel efficiency for continuous processing. Both versions are integrated in our intelligent control platform for optimised burner management.

Strong Bogie Mobility System

The chain-driven self-propelled bogie runs at 5–7 m/min to allow full extraction from the furnace chamber. This design allows easy loading of large components and easy access for maintenance. The wedge locking structure may maintain stable positioning during high temperature operations to prevent quality problems caused by vibration.

Industrial Applications of Gas Fired Heat Treatment Furnace

Heavy Forging and Casting Operations

Confidently process large scale components such as wind turbine shafts and marine crankshafts. The Gas Fired Heat Treatment Furnace provides the deep heat penetration needed for grain refining of large forgings. Metallurgical integrity in critical applications is maintained by controlled cooling rates which prevent internal structural flaws.

Automotive Component Manufacturing

Meet rigorous production timelines for drivetrain components that require carburising and hardening. Our equipment controls gas to air ratios to the correct level to ensure the integrity of the atmosphere whether in batch or continuous mode. Uniform temperature means all workpieces have the same case depth and reduces rejection rates.

Aerospace Structural Fabrication

High strength aluminium alloys and titanium parts need excellent consistency of solution treatment and ageing. Localised overheating in complex geometries is avoided by convective heat transmission from high velocity burners. The system is AMS2750G compliant, and it supports your aerospace quality certifications.

Pressure Vessel and Oil & Gas Infrastructure

Post-Weld Heat Treatment (PWHT) of large diameter reactors, storage tanks and subsea equipment requires a Gas Fired Heat Treatment Furnace with reliable thermal cycles. Our furnace works in stable states with long soak times (up to 48 hours) and is efficient in relaxing residual stresses in high pressure components for severe environments.

FAQ

Q: How even is the temperature across big workpieces?

A: After 1 hour of heat preservation, deviation holds at ≤±8℃. Optimized setups can reach ±1℃. Burners sit in places that give high velocity, and control is split over multiple zones. Oversized components therefore heat evenly. Critical work meets AMS2750F Class 2 standards.

Q: What does the bogie design do for operational efficiency?

A: The bogie drives itself, so it rolls completely out of the furnace chamber. Loading and unloading then happen safely at floor level. No one has to wait on an overhead crane to get into position, and fewer workers are needed. Chain drives keep the movement steady, even with heavy loads. Rail-based systems break down more often, so this one loses less production time.

Q: Can the furnace handle different heat treatment processes?

A: Absolutely. Adjustable heating rates (50–200℃/h), configurable temperature zones, and switchable combustion modes adapt to various processes including annealing, normalizing, stress relieving, and solution treatment. Our engineering team customizes control programs to match your specific metallurgical requirements.

Q: What maintenance does the refractory lining require?

A: The 350mm fiber lining lasts a long time and asks for very little upkeep. Visual checks at set intervals show where the wear is building up. Under normal running conditions, that usually means partial repairs every 18–24 months. Because the lining is modular, a single zone can be replaced without shutting the whole furnace down.

Q: How do you ensure compliance with safety and quality standards?

A: Before anything ships, every piece of equipment gets a thorough inspection. That check follows national and industrial standards. NFPA 86 safety requirements are covered by our quality management system, and so are ISO 13577 combustion system specs. Your facility certification process gets support from our documentation packages.

Q: What customization options are available?

A: Chamber size, load capacity, temperature zones, and control system complexity shift with your production environment. Workpiece shapes vary, so we engineer for each one. Hooking up to the material handling systems you already use counts too. So do specialized atmosphere requirements. A complete design consultation is part of what our team provides, with your process parameters as the starting point.
