Metal Heat Treatment Furnace

Metal Heat Treatment Furnace | Gas-Fired Bogie Hearth Solution for Precision Thermal Processing

JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD builds Metal Heat Treatment Furnace systems for industrial-grade thermal processing. The gas-fired bogie hearth furnace comes with a 350mm refractory fiber lining. It runs at working temperatures from 550℃ up to 950℃. Temperature control precision is ≤±2℃. Production takes place in a 20,000㎡ facility. Fixed assets reach 80 million yuan, and more than 100 skilled professionals work there. These heat treatment solutions are built to be reliable. After 1-hour heat preservation, temperature uniformity stays within ±8℃. That gives consistent metallurgical results for stress relief annealing and complex thermal cycles.

What Makes Our furnace Stand Out?

Our solution combines years of industrial heating experience with the latest thermal management technology. The gas-fired bogie hearth design provides entire access to the workpiece, with the bogie able to move completely out of the furnace chamber for easy loading and unloading.

The multi-layer composite lightweight fibre lining reduces heat loss. Furnace shell temperature rise is very minimal, only ≤45℃ on furnace top and ≤40℃ on side walls, even at 950℃ working temperature. This high-grade insulation can cut energy usage by 25-57% against traditional heating furnaces.

You like the flexibility of several burn options. The switchable pulse combustion system runs in high/low fire modes and the regenerative combustion option provides further enhancement of thermal efficiency. Full workpiece loading in different heat treatment methods with variable heating rates ranging from 50-200℃/h.

Core Advantages of Our Heat Treatment Solution

Precise Multi-Zone Temperature Control

A heat treatment process needs consistency. Every zone of the furnace has its own PID loop. Temperature across the whole heating zone stays inside ±5℃. You often see uneven hardness. Workpiece deformation and surface oxidation show up too. Control at this level clears all of them. Each batch ends up with the same metallurgical properties.

Exceptional Energy Efficiency

Running costs fall sharply, because the closed heat preservation structure loses very little heat at the surface. Add the 350mm thick refractory fiber lining and you use 25-57% less energy than an ordinary heating furnace. Thermal performance stays where it should be.

Flexible Operation & Easy Loading

The self-propelled bogie system moves at 5-7m/min and can fully exit the Metal Heat Treatment Furnace chamber. This design simplifies workpiece handling-you load materials onto the bogie surface outside the furnace using overhead hoists. The electric lifting furnace door operates at 4-6m/min with a wedge locking structure for secure sealing.

Intelligent Control System

Imported PID intelligent instruments pair with the Omron PLC to give you semi-automatic operation. Temperature control zones can be set up to suit the heat treatment process you run. Some procedures need an operator to step in. Manual mode is still there for those.

FAQ

Q: Which materials does this product handle?

A: Ferrous metals go in this furnace. Non-ferrous ones work too. Stress relief annealing is one job it handles. Tempering is another. Normalizing also runs in it. The temperature can go as high as 950℃. Alloy steels fit that range. Tool steels and specialty materials do as well.

Q: How does the bogie hearth design benefit my production?

A: The bogie rolls out. That opens the whole furnace for heavy or oversized parts. Loading them is simple. One batch can keep running while you set up the next one outside the furnace. Downtime drops and productivity goes up.

Q: Is it possible to build the furnace to the dimensions you need?

A: Absolutely. You can have the furnace chamber dimensions and the loading capacity fully customized. Both get matched to what your production line needs. Our engineers then work out the best setup for your case. Workpiece size counts here. So do weight and throughput needs. All of it shapes the design.

Q: What upkeep does the combustion system need?

A: Routine checks on the burner are needed for the switchable pulse combustion system. Cleaning matters too. Natural gas quality should stay in check. From time to time, adjust the system. Over the long run, performance stays reliable. You will seldom need to step in.

Q: How fast does the furnace get up to working temperature?

A: Heating rates are adjustable from 50-200℃/h at full loading. Reaching normal working heat does not take long. Ramp-up time itself depends on how big your customized furnace is and how heavy the workpieces are.
