Walking Hearth Furnace

Walking Hearth Furnace for Steel Reheating – Advanced Industrial Thermal Processing Solution

Steel mills need reheating systems that hold material quality and still push throughput. JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD builds Walking Hearth Furnace units for continuous steel reheating. Slab output reaches up to 350 t/h, and standard billets run at 200 t/h. Heating temperatures stay between 1150–1250°C, and energy use falls as low as 1.05 GJ/t steel. Our plant covers 20,000㎡, fixed assets total 80 million yuan, and more than 100 specialized engineers work on these lines. Every thermal processing system we supply meets demanding metallurgical standards, with oxidation burning loss rates below 0.9%.

What Makes Our Walking Beam Reheating Systems Stand Out?

Compared with classic pusher type systems, this product is a step forward in technology. Stationary and moving hearths cooperate inside this innovative reheating machine. Their synchronised mechanical movements raise, advance and position the steel items, and the surface never gets touched along the way.

Scratching of the bottom surface and black oxide stains become rare problems, so your production improves. A controlled clearance stays between the workpieces all through heating, thanks to the mechanical walking beam system. Temperature spreads evenly, and heated billets come out with better surface quality.

Our dual-regenerative gas combustion technology recycles thermal energy, and provides accurate environment control. The innovative burner arrangement creates ideal heating conditions minimising scale formation. Your steel products come out with uniform metallurgical characteristics, ready for rolling processes.

Core Advantages for Your Production Line

Unlimited Furnace Length and Configurability

Unlike pusher furnaces limited by charge ratios, your system design is flexible according to production requirements. The limitless effective furnace length allows for different billet sizes including thin blanks. Individual workpiece tracking allows the processing of different steel grades in parallel.

Improved Uniformity of Walking Hearth Furnace Heating

So the gap between workpieces stays fixed. That keeps heat spread even. Every surface of your billets gets the same thermal treatment. In the soaking zones, temperature stays within ±5°C. This meets the tight metallurgical specs.

Reduced Operational Complexity

Automated systems provide precise position control and ease of furnace management. Production demands determine flexible removal of electrodes. Reserved intervals between billets speed up startup sequences. It is an entirely automatic system that requires minimal operator involvement.

Enhanced Product Quality

Your final billets do not evidence surface blemishes or contact marks. The shorter residence period and the optimised atmospheric management prevent scale formation. Your products have the surface integrity to be better for applications in high grades of steel.

Complete Engineering Support for Walking Hearth Furnace

JIANGSU YINUO covers the whole job, from first design to commissioning. Our engineering team brings several disciplines together. They take care of mechanical design and automatic control systems. Quality inspection protocols are part of their work too. Your heating needs and fuel supply shape the final setup. We build it to match those conditions.

Before delivery, every Walking Hearth Furnace part is checked. Our quality management system follows national and industrial standards for that inspection. The 20,000㎡ production facility keeps output steady for large-scale projects. Fixed assets total 80 million yuan. That base supports our advanced fabrication work.

FAQ

Q: What does the system do to cut down oxide scale?

A: Burners run at high velocity, and the air-fuel ratio is held tight. Together they keep the furnace atmosphere slightly reducing. Metal surfaces then meet less oxygen. Heating time is shorter too. Scale usually ends up under 0.9%.

Q: Can different steel grades be processed simultaneously?

A: Yes. Advanced Level 2 automation systems track each workpiece individually. The control system adjusts walking speed and zone temperatures based on specific thermal curves required for each material grade.

Q: What happens during production delays?

A: The furnace enters soaking mode where automation reduces fuel input. This maintains charge temperature while preventing grain growth and excessive scaling. Your material remains ready for rolling when production resumes.

Q: How is maintenance scheduled?

A: Once a year the big refractory work gets inspected. Burner parts are checked on a preventive basis every six months. On a regular schedule, the hydraulic walking mechanism is tested for synchronization. That keeps it running smoothly under thermal loads.

Q: Which energy efficiency numbers should we look at?

A: Performance is measured through Specific Fuel Consumption (SFC) in GJ per ton of steel heated. Our systems achieve ≤1.05 GJ/t, verified through comprehensive performance guarantee testing.
