Walking Beam Reheating Furnace

Walking Beam Reheating Furnace: Advanced High-Efficiency Thermal Processing Solution for Steel Manufacturing

JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD brings you modern Walking Beam Reheating Furnace systems engineered for strong steel billet and slab heating. With 20,000㎡ production plant, 80 million yuan fixed asset and over 100 expert specialists, we can provide you extremely precise solutions of industrial heating. The product enables heating capacity of up to 350 t/h for slabs and 200 t/h for standard billets. Temperature control is in the range of 1150-1250°C and energy consumption ≤ 1.05 GJ/t steel. To maximise material efficiency for your hot rolling processes, the oxidation burning loss rate is maintained at below 0.9%.

What Makes Our Walking Beam Heating System Different?

Old pusher furnaces drag the steel along their hearth, and the rubbing leaves flaws on the surface. Our walking beam design works in a different way. It lifts each piece and carries it through the heating zones. Billets come out free of black oxide stains and scratches.

The gap between workpieces stays the same right through the heating cycle. Heat spreads evenly over every surface because of that spacing. Localised cold spots, the ones that pull down rolling quality, never get a chance to form. Low carbon, medium carbon, high carbon or stainless steel, each grade leaves the furnace with the same even thermal treatment.

Our regenerative gas combustion system optimises the heat recovery from the exhaust gases. The single-regenerative air option gives versatility for multiple fuel sources such as blast furnace gas, mixed gas, producer gas and natural gas.

Technical Specifications

Core Advantages for Your Production Line

Strong Surface Quality

Billets come out of the furnace with no surface scratches and no contact marks. Steel spends less time touching the support beams thanks to the lift-and-carry motion. Product integrity holds up for the rolling steps that follow.

Exceptional Heating Uniformity

There is clear space between the workpieces. Radiant heat then reaches every surface in an even way. Across the whole charge, temperature differences stay small. That gives you a more consistent final product.

Unlimited Production Flexibility

The effective Walking Beam Reheating Furnace length is not constrained by pusher charging ratios. You can process thin blanks and various raw material dimensions within the same system. Electrodes withdraw flexibly according to production demands, and reserved gaps between billets reduce furnace heating-up time.

Precise Automation Control

Advanced positioning systems track each billet's location and temperature profile. Full automatic operation becomes straightforward, synchronizing with your rolling mill speed to minimize scale loss and energy waste.

Operational Efficiency

Simple operation reduces training requirements for your workforce. The system accommodates production schedule changes without compromising heating quality or creating material handling bottlenecks.

Walking Beam Reheating Furnace FAQ

Q: How does the walking beam mechanism prevent surface defects on my steel?

A: Steel and the support structures touch only briefly, because the motion lifts and carries the load. Contact points keep changing. So the system stops cold spots from forming in one place. Those spots are what cause black marks or uneven heating.

Q: Can one heating cycle take billets of different sizes in your furnace?

A: Yes. With the independent walking mechanism, the gap between workpieces can vary. You can run different cross-sections at the same time. No mechanical reconfiguration is needed, and material pile-ups are not a risk.

Q: What maintenance schedule should I expect for the walking mechanism?

A: Every 3 to 6 months, check the hydraulic seals and beam alignment. That keeps tracking accuracy in place. Once a year, refractory checks keep thermal efficiency stable over the long term.

Q: How much energy savings can I expect compared to pusher furnaces?

A: Expect a drop of 10-15% in specific fuel consumption, thanks to better burners and thicker insulation. Waste heat normally lost up the stack gets recovered by the regenerative combustion system.

Q: What happens during mill delays or production interruptions?

A: Billets move back and forth on the walking beam. That keeps their temperature even. They will not sag or weld together. When downtime hits without warning, this setup still protects product quality.
