High-Performance Hydraulic Walking Beam Furnace System for Steel Reheating and Forging Applications
JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD builds industrial heating equipment. One of our main lines is a modern Hydraulic Walking Beam Furnace System, made for thermal processing that has to be precise. Our plant covers 20,000㎡ and holds 80 million yuan in fixed assets. More than 100 skilled professionals work here. The furnace systems we deliver heat slabs at up to 350 t/h and billets at up to 200 t/h. Heating temperatures run from 1150–1250°C. Unit heat consumption stays as low as ≤1.05 GJ/t. Temperature holds even across the whole load. Oxidation burning loss stays below 0.9%, and the material moves through without a scratch. Metallurgical quality comes out strong.
What Makes Our system Stand Out?
This product marks a step forward in continuous heating for steel and metallurgy. Older pusher furnaces work another way. Here, precision hydraulics lift each workpiece, push it ahead, then lower it again on the way through the heating chamber. That walking motion also clears surface scratches and black oxide stains. Gaps between billets stay right, so the heat spreads evenly.
You need dependability and efficiency for your production line. This technology overcomes key difficulties such as material pile ups, uneven heating and high energy consumption. The furnace uses dual gas regenerative combustion technology and evaporative cooling for walking beams which provides energy savings up to 15% compared to typical conveyor systems.
Hydraulic drive system synchronisation precision of less than a millimetre is achieved. The beam is moved smoothly and in coordination by means of high precision proportional valves, magnetostrictive linear transducers and closed loop PLC algorithms. This technology allows your facility to handle a range of workpiece sizes – from normal billets to large slabs – with no compromise to heating quality or cycle time.

Core Technical Advantages You Can Count On
Flexible Material Handling
Unlimited effective furnace length design, no limitation of pusher charging ratio. The same efficiency may be used to heat thin blanks, big slabs and a lot of raw materials.
Strong Surface Quality
Billets never touch the transport surface, so they pick up no blemishes or flaws. For high-value speciality steels and aerospace-grade materials, that counts for a lot.
Accurate Temperature Control
Keep the heat even across the whole workpiece, within ± 5°C. Leave some clearance between the materials and, using the Hydraulic Walking Beam Furnace System, you can heat them from the bottom side only. That stops cold spots from forming, and cold spots can damage material qualities.
Easier Operations
Electrodes can be retracted flexibly according to your production needs. The furnace heating-up time is greatly reduced by the gaps left between the billets during start-up procedures.
Fully Automated Capability
The digital positioning control allows fully automatic operation. Real time tracking of material position eases production planning and quality documentation
Where You Can Apply This Technology?
Hot Rolling Mill Reheating
Large-scale steel producers use this system to reheat thick slabs before rolling operations. The consistent internal temperature profile ensures optimal rolling conditions even for ultra-wide materials.
Heavy Forging Operations
Aerospace and energy sectors rely on our Hydraulic Walking Beam Furnace System for transporting massive ingots through precise heating cycles. The hydraulic movement prevents cold spots that occur with contact-based transport methods.
Seamless Pipe Production
Pipe mills need a surface finish that stays clean. The hydraulic mechanism does not slide, so the exterior keeps its quality through the high-temperature soaking phases. Controlled atmosphere integrity holds up for the whole process.
Quality Assurance You Can Trust for Your Hydraulic Walking Beam Furnace System
Both mechanical integrity and thermal performance get checked in our quality control process. Leakage tests on the hydraulic cylinders and checks on synchronization accuracy come next, and every product goes through them. Laser alignment reports are included as well. They confirm the beams run in perfect parallel across their working range.
Ultrasonic testing of beam weldments is one part of material testing. Thermal imaging finds refractory hot spots. Hydraulic oil cleanliness meets ISO 4406 standards. Pressure pulse testing checks manifold durability. Dry run cycle tests are part of final commissioning. Heat load uniformity tests also happen at that stage. They run under maximum thermal expansion conditions.
FAQ
Q: What keeps several hydraulic cylinders in sync?
A: High-precision proportional valves do the control work, and magnetostrictive linear transducers sit alongside them. Closed-loop PLC control algorithms tie the setup together. Sync across all hydraulic cylinders stays within a sub-millimeter, so beam misalignment during operation gets prevented.
Q: How often do hydraulic parts usually need servicing?
A: Check the hydraulic filters once a month. That keeps the system running well. Every 3,000 operating hours, book a full diagnostic and an oil analysis. Do this and the machine stays reliable, and surprise breakdowns are less likely.
Q: Is it possible to run material of different sizes at the same time?
A: Yes. Batch-flexible walking cycles come from the digital control system. Stroke length gets adjusted on its own, based on the dimensions of the workpieces loaded. That flexibility gives you more room when you plan production.
Q: What happens with high-temperature scale buildup on this system?
A: Under the walking beams there is a scale-pit and flushing system built for this job. Iron oxide scale gets removed safely, and production keeps running. Clearance between the beams and the workpieces stays consistent.
Q: What happens in the event of a hydraulic power failure?
A: Safety comes first. Accumulator banks are built into the system, and so are fail-safe locking valves. Together they lower the beams in a safe way and keep the load where it is. That way the equipment does not get damaged and your investment stays protected.
