Continuous Pusher Type Furnace

Continuous Pusher Type Furnace - Advanced Industrial Reheating Solution for High-Volume Steel Processing

JIANGSU YINUO THERMAL ENERGY TECHNOLOGY builds Continuous Pusher Type Furnace systems for heavy industrial use. They are made to run at high throughput and to keep energy use low. Pushing reheating furnaces from our line take heating loads of up to 200 t/h. Working temperatures sit between 1150–1250°C, and energy use comes in at roughly 1.1 GJ/t steel. We have 20,000㎡ of manufacturing space and 80 million yuan in fixed assets. Our team numbers more than 100 engineers. The thermal processing equipment we supply is built to hold up under the tough demands of structural steel, low-alloy steel, and reliable carbon steel production.

What Makes Our furnace Different?

Our furnace differs from traditional batch heating systems by using a mechanical pusher to transport billets through a series of zones for heating, soaking and cooling. This removes heat variations generated by successive door openings during batch processing.

You get a uniform heating quality for all workpieces. The continuous flow design removes production constraints in high volume industrial operations.

Many fuels can run through our system. Examples are blast furnace gas, mixed gas, producer gas and natural gas. With that kind of flexibility, you can trim running costs to match whatever energy supplies you have on hand.

Waste heat gets recovered efficiently thanks to the dual-regenerative air-gas combustion system. Fuel use drops by 20 to 30 percent next to conventional batch furnaces.

Technical Specifications

Key Operational Advantages

Lower Investment Requirements. Our pusher furnace design needs far less capital spending than walking beam or roller hearth options. That means your money comes back sooner.

Shorter Construction Period. Simple mechanical systems and standard modules cut down installation time. Compared with complex furnace types, your line starts running weeks earlier.

Simple Operation - The straightforward pusher mechanism requires minimal training. Your operators can master the system quickly, reducing onboarding costs.

Easy Maintenance Access - Fewer moving parts mean reduced maintenance requirements. Replacement components are readily available, minimizing downtime risks.

Lower Skill Requirements - The intuitive control interface allows technicians with basic training to operate the Continuous Pusher Type Furnace effectively. This reduces labor costs in regions with limited skilled workforce availability.

Comprehensive Engineering Support

From first design to commissioning, we handle the whole project. Mechanical engineers work on our team. So do automatic control specialists and quality inspection professionals.

Before a furnace ships, it goes through hard testing. Temperature uniformity surveys check that heating stays even in every zone. That check follows industry standards.

Pusher speed is run by a PLC and changes on its own to match your metallurgical needs. Variable frequency drives keep takt time tight, so throughput stays where it should be.

Our precision-aligned silicon carbide rails prevent tray buckling during push cycles. Synchronized intermediate drives handle long furnace lengths without compressive stress buildup.

Continuous Pusher Type Furnace Quality Management You Can Trust

Before shipment, each system gets inspected against national and industrial standards. Our quality management procedures are thorough, and they keep performance reliable.

We use infrared thermography to check how the refractory lining is holding up. It tells us whether the insulation still works as it should. Accuracy tests on the system then confirm that thermocouple and instrument loops give exact readings.

We conduct pusher cycle stress testing under maximum load conditions. This prevents jamming and rail deformation during operation.

Some jobs call for tight control of the atmosphere. When that happens, we run helium leak detection and pressure decay testing. That way the protective gas stays pure through specialized heat treatment in the Continuous Pusher Type Furnace.

FAQ

Q: How do you stop cold spots from forming on heated billets?

A: Skid pipes get high-insulation coverings. We also tune the soaking zone length. Heat then spreads evenly across the billet surface by conduction.

Q: What fuel flexibility does the system offer?

A: Blast furnace gas works. So do mixed gas, producer gas, and natural gas. The control system adjusts the combustion parameters on its own.

Q: Can the furnace handle varying billet sizes?

A: Yes. The PLC-controlled pusher stroke adjusts for different billet lengths within the hearth width specifications. This provides production flexibility.

Q: How does energy management work during mill delays?

A: The automation system includes a holding mode that ramps down burner output. This maintains temperature while minimizing fuel consumption during temporary production pauses.

Q: How long does refractory usually last?

A: The high-alumina monolithic linings we supply last 5 to 8 years. That figure holds when the lining is looked after properly and thermal cycling stays under control. We also hand over maintenance guidelines that spell out how to get a longer service life.

Q: Is retrofitting older furnaces possible?

A: Absolutely. We upgrade existing pusher furnaces with high-velocity regenerative burners and advanced combustion management systems. This improves efficiency by up to 25%.
