These furnaces ensure metals achieve optimal malleability, enhancing efficiency and product quality in industries like construction, automotive, and aerospace. Jiangsu Yinuo, based in Xuzhou, China, is a global leader in manufacturing advanced pusher steel heating furnaces. This guide explores the technology, processes, and applications of these furnaces, highlighting why Jiangsu Yinuo’s solutions are trusted worldwide.
The Importance of Pusher Steel Heating Furnaces
Pusher steel heating furnaces are designed to heat large volumes of steel continuously, making them a cornerstone of high-throughput steel processing. By pushing steel through a heating chamber, these furnaces deliver uniform temperatures, essential for consistent material properties during rolling or forging. Their ability to handle heavy loads and maintain precise thermal conditions ensures efficiency, reduces defects, and supports the production of high-quality steel products, from structural beams to automotive components.
Purpose of Steel Heating
The primary purpose of heating steel in pusher furnaces is to prepare it for deformation processes by increasing its ductility. Preheating to temperatures between 1100°C and 1250°C softens steel, reducing the mechanical energy required for rolling or forging. This process minimizes internal stresses, prevents cracking, and ensures uniform microstructure, improving the mechanical properties of the final product. Consistent heating also enhances energy efficiency and reduces wear on downstream equipment, optimizing production.
Commonly Processed Steel Types
Pusher steel heating furnaces process various steel types to meet industrial demands. Carbon steel, used in construction and machinery, is preheated for rolling into plates or bars. Alloy steels, containing elements like chromium or nickel, are treated for automotive and aerospace applications requiring enhanced strength. Stainless steel, valued for corrosion resistance, undergoes preheating for forming into sheets or tubes. These furnaces’ versatility ensures they support a wide range of steel grades and applications.
How Pusher Steel Heating Furnaces Operate
Pusher steel heating furnaces are continuous systems that move steel through a heating zone using a pusher mechanism. They are engineered to deliver precise temperature control, uniform heat distribution, and efficient energy use, ensuring steel reaches the optimal temperature for processing. Their robust design and advanced technology make them ideal for large-scale steel production.
Core Components
The heating chamber, lined with high-grade refractory materials, withstands temperatures up to 1300°C while minimizing heat loss. Temperature control systems, equipped with advanced PID controllers, maintain precise thermal profiles for consistent heating. Burners, often gas-fired or regenerative, provide the heat energy, with electric options available for cleaner operation. The pusher mechanism, typically hydraulic or mechanical, moves steel billets or slabs through the furnace, ensuring smooth and continuous operation. Atmosphere control systems regulate oxygen levels to prevent scaling or oxidation.
Operational Mechanism
In a pusher furnace, steel is loaded onto a hearth or skid at the furnace’s entry. The pusher mechanism advances the steel through preheating, heating, and soaking zones, each with specific temperature settings. In the preheating zone, steel is gradually warmed to avoid thermal shock. The heating zone raises the steel to its target temperature, typically 1100–1250°C, while the soaking zone ensures uniform heat penetration. Once heated, the steel is discharged for rolling or forging, with automated systems ensuring precise timing and temperature control.
Applications in Steel Processing
Pusher steel heating furnaces are integral to steel processing, supporting a range of applications that require high-quality, uniformly heated materials. Their continuous operation and precision make them essential for industries producing critical components.
Hot Rolling Mills
In hot rolling mills, pusher furnaces preheat steel billets, blooms, or slabs for rolling into sheets, plates, or structural shapes. Uniform preheating ensures consistent material properties, reducing rolling forces and improving surface quality. These furnaces are critical for producing steel used in construction, shipbuilding, and infrastructure, where strength and reliability are paramount. Their high throughput supports the demands of large-scale rolling operations.
Forging and Forming
The forging industry uses pusher furnaces to heat steel billets or ingots to temperatures that enable deformation under compressive forces. Preheating ensures metals are ductile, allowing the creation of complex shapes like gears, shafts, or crankshafts without cracking. Precise temperature control maintains material integrity, essential for producing high-strength components for automotive and heavy machinery applications, where performance under stress is critical.
Automotive Manufacturing
Automotive manufacturers rely on pusher furnaces to preheat steel for forging and rolling processes, producing parts like engine components, chassis, and suspension systems. Uniform heating ensures parts meet strict durability and safety standards. The continuous operation of pusher furnaces supports high-volume production, delivering consistent quality for standardized components, a key requirement in the automotive sector’s fast-paced environment.
Construction and Infrastructure
In construction, pusher furnaces preheat steel for rolling into beams, rebar, and other structural elements. Consistent heating ensures these components have the strength and toughness needed for buildings, bridges, and pipelines. The ability to process large steel loads efficiently makes pusher furnaces ideal for meeting the high demand for construction materials, supporting infrastructure development worldwide.

The Preheating Process in Pusher Furnaces
Preheating in pusher steel heating furnaces is a multi-stage process that ensures steel is optimally conditioned for rolling or forging. Each stage is carefully controlled to achieve uniform temperatures and material properties.
Preheating Zone
In the preheating zone, steel is gradually warmed to avoid thermal shock, typically starting at ambient temperatures and reaching 600–800°C. This stage reduces internal stresses and prepares the material for higher temperatures. Uniform heat distribution is critical to prevent uneven expansion, which could cause defects. Pusher furnaces use controlled burner settings and advanced insulation to ensure consistent preheating across large steel loads.
Heating Zone
The heating zone raises the steel to its target temperature, usually 1100–1250°C, depending on the steel grade and process. This stage ensures the material becomes ductile enough for deformation. Precise temperature control prevents overheating, which could alter microstructure or cause scaling. Jiangsu Yinuo’s furnaces employ PID controllers and regenerative burners to maintain tight thermal tolerances, ensuring high-quality heating for rolling or forging.
Soaking Zone
In the soaking zone, steel is held at the target temperature to ensure uniform heat penetration, particularly for thick slabs or blooms. This stage eliminates temperature gradients, ensuring the core and surface are equally malleable. Atmosphere control, using inert gases or controlled combustion, prevents oxidation or decarburization. The furnace’s pusher mechanism ensures steady movement, maintaining consistent soaking times for optimal material preparation.
