Pusher slab furnaces are integral to steel manufacturing, preheating large steel slabs to precise temperatures for hot rolling and other forming processes. These continuous furnaces ensure slabs achieve uniform malleability, enhancing efficiency and quality in industries like construction, automotive, and shipbuilding. At Jiangsu Yinuo Thermal Energy Technology Co., Ltd., based in Xuzhou, China, we lead the industry with advanced pusher slab furnace solutions. This guide explores the technology, processes, and applications of pusher slab furnaces, showcasing why our expertise is trusted globally.
The Role of Pusher Slab Furnaces in Steel Processing
Pusher slab furnaces are designed for high-volume, continuous heating of steel slabs, preparing them for hot rolling into plates, sheets, or coils. We engineer our furnaces to deliver consistent temperatures across large, flat slabs, ensuring uniform material properties critical for downstream processing. This precision minimizes defects, reduces energy consumption, and supports the production of high-quality steel products, making our furnaces indispensable in modern steel mills.
Purpose of Slab Preheating
Our pusher slab furnaces heat steel slabs to temperatures between 1100°C and 1250°C, enhancing ductility for hot rolling. This reduces the mechanical energy required, lowering operational costs and equipment wear. Uniform preheating eliminates thermal gradients, preventing cracks and ensuring a consistent microstructure. By optimizing material properties, we enable the production of steel with superior strength and surface quality, essential for applications in infrastructure and manufacturing.
Types of Steel Slabs Processed
We design our pusher slab furnaces to process various steel types, addressing diverse industrial needs. Carbon steel slabs, common in construction, are preheated for rolling into structural plates. Alloy steel slabs, enhanced with elements like manganese or nickel, are processed for automotive and machinery applications requiring high strength. Stainless steel slabs, valued for corrosion resistance, are heated for forming into sheets or coils. Our furnaces’ versatility ensures compatibility with multiple steel grades, supporting a wide range of production requirements.
How Pusher Slab Furnaces Operate
Pusher slab furnaces function as continuous heating systems, moving steel slabs through thermal zones to achieve precise preheating. We build our furnaces with advanced technology to ensure uniform heat distribution, efficient energy use, and robust performance, making them ideal for high-throughput steel processing in demanding industrial environments.
Core Components
Our pusher slab furnaces feature a heating chamber lined with high-grade refractory materials, capable of withstanding temperatures up to 1300°C while minimizing heat loss. We equip them with advanced temperature control systems, using PID controllers for precise thermal regulation. Gas-fired regenerative burners provide efficient heat, with electric options for cleaner operation. The hydraulic pusher mechanism ensures smooth, continuous movement of slabs. We incorporate atmosphere control systems to regulate oxygen levels, preventing scaling or oxidation during heating.
Operational Mechanism
In our pusher slab furnaces, steel slabs are loaded onto skids or a hearth at the entry point. The pusher mechanism advances the slabs through preheating, heating, and soaking zones, each with tailored temperature settings. We gradually warm slabs in the preheating zone to avoid thermal shock, followed by the heating zone, where temperatures reach 1100–1250°C. The soaking zone ensures uniform heat penetration across the slab’s thickness, preparing it for discharge to rolling mills. Our automated systems maintain precise timing and temperature control for optimal results.
Applications in Steel Manufacturing
Pusher slab furnaces are vital across steel-related industries, enabling the production of high-quality components with consistent properties. Our furnaces support continuous operation, delivering the precision and efficiency needed for large-scale manufacturing.
Hot Rolling Mills
Our pusher slab furnaces preheat steel slabs for hot rolling, ensuring they are ductile enough to form sheets, plates, or coils. Uniform heating reduces rolling forces, enhancing energy efficiency and surface quality. We support the production of steel for construction, shipbuilding, and infrastructure, where reliability is critical. Our high-throughput furnaces meet the demands of large-scale rolling mills, ensuring consistent output and quality for high-volume production.
Plate and Sheet Production
In plate and sheet production, we use our pusher furnaces to heat slabs for rolling into flat products used in bridges, pipelines, and pressure vessels. Precise temperature control ensures uniform thickness and surface finish, meeting stringent industry standards. Our furnaces’ ability to handle large slabs efficiently supports the production of heavy plates for structural applications, contributing to the durability and safety of critical infrastructure projects.
Automotive and Transportation
Our pusher furnaces preheat steel slabs for rolling into sheets used in automotive bodies, chassis, and structural components. Uniform heating ensures these parts meet strict strength and safety requirements. We design our furnaces for continuous operation, supporting high-volume production of standardized components, a key requirement for the automotive and transportation sectors, delivering consistency and efficiency in demanding production environments.
Shipbuilding and Heavy Industry
In shipbuilding, our pusher furnaces preheat slabs for rolling into plates used in hulls and decks, requiring high strength and corrosion resistance. We also support heavy industry applications, such as manufacturing steel for cranes and mining equipment. Our furnaces’ robust design and high capacity ensure they meet the rigorous demands of these sectors, producing reliable, high-quality steel for critical applications.

The Preheating Process in Pusher Slab Furnaces
Preheating in our pusher slab furnaces is a multi-stage process that ensures steel slabs are optimally conditioned for hot rolling. We control each stage to achieve uniform temperatures and material properties, critical for high-quality steel production.
Preheating Zone
In the preheating zone, we gradually warm steel slabs from ambient temperatures to 600–800°C to avoid thermal shock. This stage reduces internal stresses and prepares slabs for higher temperatures. Our furnaces ensure uniform heat distribution, preventing uneven expansion that could cause defects. We use controlled burner settings and advanced insulation to maintain consistent preheating across large, flat slabs, setting the stage for efficient processing.
Heating Zone
Our heating zone raises slabs to their target temperature, typically 1100–1250°C, ensuring ductility for rolling. We prevent overheating, which could alter microstructure or cause scaling, using precise temperature control via PID controllers. Our regenerative burners optimize energy use, delivering high heat output with minimal fuel. This stage ensures slabs are uniformly heated, critical for achieving consistent mechanical properties and surface quality in the final rolled product.
Soaking Zone
In the soaking zone, we hold slabs at the target temperature to ensure uniform heat penetration, particularly for thick slabs up to 300 mm. This eliminates temperature gradients, ensuring the core and surface are equally malleable. Our atmosphere control systems, using inert gases or controlled combustion, prevent oxidation or decarburization. The pusher mechanism maintains steady movement, ensuring consistent soaking times for optimal slab preparation before discharge to rolling mills.
