Top And Bottom Fired Walking Beam Furnace for Industrial Steel Heating – High-Efficiency Thermal Processing Solution
JIANGSU YINUO THERMAL ENERGY TECHNOLOGY CO., LTD builds Top And Bottom Fired Walking Beam Furnace systems for steel plants that reheat metal in large volumes. Floor space at our factory adds up to 20,000㎡. More than 100 technical professionals work there. Slabs run through our furnaces at rates up to 350 t/h, and the oxidation burning loss rate stays under 0.9%. Working temperatures sit between 1150–1250°C. Unit heat consumption comes in at ≤1.05 GJ/t steel. So thermal precision and energy savings both hold up under heavy industrial use.

What Makes Our furnace Different?
A dual-firing layout puts burners above the charge and below it as well. That arrangement is what our walking beam furnace runs on. Cold spots and surface defects show up often in traditional pusher furnaces. This design removes both of them.
Steel products travel through the heating zones on the reciprocating beam mechanism. Nothing drags along the way. Nothing gets scratched either. You see the difference right away. Black oxide marks never form. Surfaces stay free of damage. Billets come out evenly heated and ready for downstream processing.
A gap is kept between workpieces, so heat stays even across each cross-section. Material gets the same heat treatment on all sides. That matters for holding metallurgical properties in high-grade steel applications.

Core Advantages You Can Measure
Uniform Heating Without Surface Defects
Billets move through the furnace with a set gap between them. That stops surface scratches caused by friction. Each piece also reaches the target temperature evenly over its full cross-section.
Flexible Production Capability
Pusher furnaces have limits tied to charging ratios. This system has no cap on effective furnace length. Thin blanks and different raw materials can run without reconfiguration. When production demands change, you can adapt fast.
Reduced Operational Costs
Oxidation burning loss stays under 0.9%. Energy use sits at ≤1.05 GJ/t. Both numbers mean less material waste and lower fuel bills. Natural gas and blast furnace gas are among the fuels the Top And Bottom Fired Walking Beam Furnace combustion system can run on.
Precision Control and Automation
Each billet gets exact positioning control from the walking beam mechanism. With that precision, full automation is easy to add. Labor needs go down. Process consistency goes up.
Faster Startup and Flexible Operation
Gaps left between billets let electrodes pull back as your production schedule needs. With this design, furnace heating-up time is shorter. That applies when operations start again after maintenance or a shift change.
Where This Furnace Delivers Maximum Value?
Hot Strip Mill Operations
Slabs get reheated before automotive or appliance-grade steel can be rolled. Let the temperature drift across a massive slab and your strip gauge tolerances go with it. Our dual-firing setup holds the heat even, which is what high-volume rolling runs on.
Heavy Plate Manufacturing
Thick plates need deep heat penetration without thermal warping. The top and bottom firing ensures your plate cores reach rolling temperature simultaneously with the surface, eliminating internal stress and dimensional issues.
Specialty Steel Production
Take aerospace-grade bars. Or tool steel. Any high-alloy long product, really. Surface damage on that kind of stock is not something you can accept. Our Top And Bottom Fired Walking Beam Furnace keeps oxygen exposure low and stops mechanical scratching. Your high-value material comes out the way it went in.

Top And Bottom Fired Walking Beam Furnace Backed by Manufacturing Excellence
Our 20,000㎡ production facility houses complete manufacturing capabilities supported by 80 million yuan in fixed assets. Every furnace undergoes rigorous quality inspection according to national and industrial standards before delivery.
Over 100 professionals work here, among them mechanical engineers, automatic control specialists, and quality inspection experts. Help runs from the first design through installation and commissioning. Several disciplines sit on one team, so your furnace fits into the production line without trouble.

FAQ
Q: How does your furnace eliminate black spots on heated steel?
A: Heat-shadow effects go away when bottom burners work together with specialized skid buttons. The trick is offset contact points. Bottom and top surfaces then reach the same temperature. That stops cold spots, and cold spots are what leave black oxide marks.
Q: What fuel flexibility do you offer?
A: Natural gas runs in our combustion system. So do coke oven gas, blast furnace gas, and producer gas. Multi-fuel blends work too. Fuel sources can be switched as supply and price change. No major modifications are needed.
Q: How do you maintain heating uniformity with different material sizes?
A: Gap control technology sits inside the walking beam mechanism. Slabs of different widths and thicknesses can then run in one campaign at the same time. Each piece still holds its thermal uniformity.
Q: What maintenance does the water-cooling system require?
A: A closed-loop treated water circuit keeps the system running. That setup guards against scaling and corrosion. For the long haul, we suggest checking water quality on a regular schedule. Ultrasonic thickness testing of the pipes should also be done from time to time. Both help the system stay reliable.
Q: Can your furnace integrate with existing automation systems?
A: Yes. Our furnace design supports Level 2 automation integration for dynamic tracking and heat model optimization. The precise positioning control of the walking beam mechanism makes automation implementation straightforward.
