Walking Hearth Furnace For Bloom Heating – Industrial Steel Heating Solution with Strong Precision and Efficiency
JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD specializes in advanced Walking Hearth Furnace For Bloom Heating systems. We build them for steel lines that run at high capacity. Over 100 skilled professionals work on our team. Our 20,000㎡ production facility is backed by 80 million yuan in fixed assets. Furnace temperatures reach 1150–1250°C. Heating capacity goes up to 350 t/h for slabs, and to 200 t/h for billets. Every unit we ship uses regenerative combustion technology. Unit heat consumption holds at ≤1.05 GJ/t steel. Oxidation burning loss stays below 0.9%. For bloom heating, that means strong metallurgical quality and efficient operation.
What Makes Our Walking Beam Heating System Stand Out?
The product moves workpieces with a mechanical lift-and-shift transport mechanism. Nothing gets pushed along the way it used to be. Sliding friction between workpieces drops out of the picture. Surface scratches go away with it. So do black oxide marks. Both of those spoil high-grade steel quality.
Heat reaches your bloom from every angle, 360 degrees. A clearance is kept between workpieces. That gap is what spreads the temperature evenly over all surfaces. Metallurgical integrity rests on it. Low carbon, medium carbon, high carbon, and stainless steel grades all depend on the same thing.
Fuel choice stays open. The system can burn blast furnace gas or mixed gas. Producer gas works too. Natural gas is fine as well. A dual gas regenerative combustion mode pulls the most heat from the fuel. Harm to the environment stays low.

Core Advantages for Your Production Line
Uniform Temperature Distribution
The walking mechanism keeps set gaps between blooms. Heat then moves through each one the same way. Over the full length of the workpiece, temperature stays within ±5°C. That matters for seamless pipe production. Heavy structural profile mills depend on it too.
Zero Surface Damage
Pusher furnaces drag workpieces along. Our vertical lift-and-shift motion avoids that contact. Contact friction is gone. Bloom surfaces come out with no scratches. Indentations do not appear. Cold spots are absent too. For high-alloy steel applications, that counts. Surface quality there has a direct effect on what the final product is worth.
Flexible Operation Control
Bloom dimensions and steel grades decide the residence times, and the automated positioning system makes the adjustments for you. Electrodes can be pulled back during low-demand periods. That shortens furnace heating-up time, and energy use drops by 15-20% next to conventional systems.
Extended Furnace Walking Hearth Furnace For Bloom Heating Length Capability
Pusher charging ratio limits do not hold this design back. Thin blanks go through it. So do raw material sizes that vary, and blooms as long as 12 meters, all at the same time. Heavy structural mills and special steel forging operations find a good fit here.
Simplified Maintenance Access
Precise electrohydraulic control brings full automation. Operators can still step in by hand when they need to. The modular refractory design lets repairs target one spot, so the furnace never has to shut down completely. Uptime stays high as a result.
Industrial Applications of Walking Hearth Furnace For Bloom Heating
Seamless Pipe Manufacturing
Every bloom you feed in gets heated evenly around its whole circumference. That is what stops the wall thickness from drifting off centre while the piercing runs. On top of that, the furnace atmosphere is kept under control. Costly alloy grades lose far less carbon that way.
Heavy Structural Profile Production
This product takes on the heavy blooms used to make H-beams and rail track. Different sizes can run at the same time. Each piece still holds its own temperature profile.
Special Steel Forging
Some blooms need a set time inside the furnace. High-carbon and stainless grades fall into that group, and flexible cycles cover them. Dust and fierce ambient heat are normal around forging work. The system keeps running in those conditions.
Quality Assurance and Engineering Support
No furnace ships before a full inspection. National and industrial standards set the checklist. Our quality control team works through every point on it. Chamber temperature has to stay even. The refractory must be sound. Hydraulics are tested for steady operation. Combustion efficiency gets measured. Automation logic is run through its paces.
Engineering help comes with the order, from first drawing to handover. Our team handles furnace design, manufacturing, installation, commissioning, and project management. Mechanical engineers work alongside automatic control specialists. Quality inspectors sit on the same team. Their goal is simple. The furnace has to fit the production line you already run.
The lining is high-alumina, so heat stays where it belongs. Shell temperature holds below 80°C. Heat-resistant alloy support buttons sit at the Walking Hearth Furnace For Bloom Heating bloom contact points. They keep heat from draining away there, which stops cold spots from forming.
FAQ
Q: How does this furnace prevent bloom surface damage?
A: Sliding friction is gone completely, because the motion lifts and shifts vertically. No bloom ever gets dragged over a surface. The clean finish that high-grade steels need stays intact.
Q: Can it handle different bloom sizes simultaneously?
A: Yes. The independent walking cycle and automation system accommodate varying spacing and residence times for different bloom cross-sections in the same heating cycle.
Q: What energy savings can I expect versus a pusher furnace?
A: Bottom heating that has been tuned up plus regenerative burners usually cut energy use by 15-20%. You also get steadier temperatures across the load.
Q: How are cold spots managed on bloom support areas?
A: We use specialized heat-resistant alloy buttons on water-cooled beams. These riders minimize heat extraction from bloom contact points while maintaining structural integrity.
Q: How long does the refractory lining last?
A: Good maintenance and steady thermal cycles keep a solid lining in service for 5 to 8 years. After that it needs major repairs. How hard you run the unit decides where you land in that range.
