Walking Beam Furnace for Steel Reheating | High-Efficiency Industrial Heating Solution
JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD specializes in advanced Walking Beam Furnace systems. Steel mills run them for continuous steel reheating. Our plant covers 20,000㎡. More than 100 skilled professionals work on these machines. Slabs heat at up to 350 t/h, and billets at up to 200 t/h. Unit heat consumption comes in at ≤1.05 GJ per ton. Oxidation burning loss rates stay below 0.9%. Strong thermal efficiency and solid material quality follow for many metallurgical applications.
What Makes Our furnace Different?
Our device has a distinct lift-and-carry system that avoids surface damage common to conventional pusher furnaces. The moving beam system picks up workpieces, moves forward and replaces them on the stationary beams, giving ideal clearance for an even distribution of heat.
Scratches no longer show up on your steel products with this new design. Black oxide markings go away too, and so do skid marks. Low carbon steel, stainless steel and high carbon grades all run through it. The whole chamber holds a uniform heating temperature of 1150-1250°C.
The method accepts a variety of work piece shapes including conventional billets and slabs. Depending on your production architecture, you can pick from several charging options such as side charging with side discharging or end measuring feeding.

Key Advantages for Your Production
Strong Surface Quality
During walking operation the walking beam mechanism lifts the billets right out of the hearth. Surface flaws from friction cannot form. Your end goods come out scratch-free and free of contact marks. Downstream processing then continues without any problems.
Very Good Heating Uniformity
Spacing workpieces apart allows hot gases to move freely across all surfaces. This 360-degree exposure to heat means that internal temperature profiles are uniform and crucial to precision rolling operations and metallurgical integrity.
Furnace Length Unlimited
Our Walking Beam Furnace is not limited by charge ratios like a pusher furnace, and can accommodate long effective lengths. This versatility makes it possible to use thin blanks and different raw material dimensions without any loss of heating performance.
Operational Simplicity
The device also allows for adjustable retraction of electrodes as per manufacturing needs. Reserved gaps between billets minimise the furnace heating-up time during startup significantly, minimising the energy waste and enhancing the overall efficiency.
Precision Automation & Control
Sophisticated positioning devices are used to track the location of each billet during the heating cycle. This accuracy allows for full automatic operation with minimal manual intervention, therefore decreasing labour costs and enhancing uniformity of manufacturing.
Walking Beam Furnace FAQ
Q: What keeps the surface from getting damaged in a walking beam system?
A: During advancement, the lifting mechanism lifts the workpieces fully off the stationary supports. Sliding friction is gone. On water-cooled beams, contact points are few and they use high-temperature alloy riders. Heat then spreads evenly and no permanent marks are left behind.
Q: Can your furnace handle different steel grades simultaneously?
A: Yes, the precise temperature control across heating zones accommodates various steel grades. However, we recommend grouping similar materials for optimal heating curves and metallurgical results.
Q: What fuel options provide the best energy efficiency?
A: Natural gas paired with regenerative combustion gives very good efficiency. Integrated steel plants can also run blast furnace gas or mixed gas. That cuts running costs and still meets performance standards.
Q: How long does furnace maintenance typically take?
A: All workpieces can be fully emptied out thanks to the walking beam design. No dummy bars are needed, and that makes it easier for crews to get at the unit for service. Routine inspections usually take 24-48 hours. Refractory lining replacement is done during the planned annual shutdowns.
Q: What happens during unexpected power interruptions?
A: When power fails, walking beam structures still get the cooling they need. Emergency backup systems keep it going. Control logic runs on UPS units. Inside the machine, gravity-fed or diesel-pumped water cooling holds thermal damage back.
Q: Can we get a custom build for unusual production needs?
A: Yes. Our engineers start with your heating capacity and the size of your workpieces. Fuel supply counts too. So does the layout of your plant. The furnace gets built around all of it. From the first design drawing through commissioning, we cover the whole job.
