Pusher Type Furnace
Pusher Type Furnace
Are you looking for a heat treatment system that can handle high production, heavy loads, and consistent quality without slowing down your operations?
At our company, we design and manufacture Pusher Type Furnaces that deliver reliable, repeatable, and high-volume thermo-chemical heat treatment for industries around the world. These furnaces are built to process large quantities of components with less product variety while maintaining tight control over temperature and atmosphere.
In this guide, we explain how Pusher Type Furnaces work, where they are used, and why they are one of the most trusted solutions for carburizing, hardening, annealing, stress relieving, solution treating, and ageing.
What Are Pusher Type Furnaces?
Pusher Type Furnaces are continuous heat treatment systems where we move trays or fixtures loaded with components through the furnace chamber using a mechanical pushing system. Each new charge pushes the previous one forward in a smooth, controlled sequence.
We use these furnaces mainly for:
Carburizing
Hardening
Annealing
...
... Stress Relieving
Solution Treating
Ageing
These furnaces are ideal for high production environments, especially when processing similar parts in large volumes.
“Consistency in heat treatment is not optional in mass production. It is essential.”
Industries and Components We Process
We design our Pusher Type Furnaces to process a wide range of automotive and industrial components worldwide.
Common Applications
We frequently process:
Transmission components
Axle components
Gear components
Shafts
Castings
Drive train components
Forgings
Engine components
Our systems support automotive manufacturers, heavy engineering units, and global industrial suppliers who demand precision and durability.
How Pusher Type Furnaces Work
In a Pusher Type Furnace, we load components onto trays placed on silicon carbide segmented skids. A hydraulic or mechanical pusher system moves each tray forward step-by-step through heating zones.
Heating Stages
Pre-heating zone
Heating zone
Soaking zone
Optional quenching section
We control each stage carefully to maintain the correct temperature and atmosphere. Recirculation—not agitation—ensures uniform heat distribution. This method allows us to achieve best-in-class repeatability.
Heating Systems and Fuel Options
We offer flexible heating systems to match production needs.
Electrically Heated Type
Clean operation
Precise temperature control
Ideal for controlled atmospheres
Gas Fired Type
Suitable for large-scale operations
Cost-effective for high volumes
We use:
LPG
Propane
Natural Gas
Our furnace atmosphere options include:
Atmosphere Type Gas Combination
Endogas System Endogas + LPG/Propane/Natural Gas
Methanol System Methanol + Nitrogen + LPG/Propane/Natural Gas
This flexibility allows us to meet global operational standards.
Advanced Temperature and Carbon Control
Precision is the heart of every Pusher Type Furnace we build.
Fully Automatic Control System
Our furnaces include:
Advanced temperature control
Carbon potential monitoring
Data tracking and acquisition
Interface for modern process control systems
Why It Matters
Better case depth control
Uniform hardness
Reduced rejection rates
Real-time process monitoring
We design every system to operate automatically, reducing manual errors and improving production efficiency.
Quenching and Washing Capabilities
We provide both free and press quenching capabilities depending on the application.
Floor Mounted Tank Design
Our design allows:
Floor mounted quenching oil tanks
Integrated washing machine tanks
No need for costly pit civil work
This reduces installation time and lowers total project cost. It also simplifies maintenance and plant layout planning.
Design Flexibility and Configuration
Every Pusher Type Furnace we manufacture is built based on production requirements, available space, and process type.
We offer:
Single row design
Multi row design
Single chamber
Multi chamber systems
Compact and Space Saving
Our furnaces feature:
Lightweight insulation
Low heat retention materials
Low external skin temperature
Robust furnace shell
The result is a compact, fail-safe, and space-saving design with modern technology.
Heavy Load Pusher Mechanism
We engineer all pusher mechanisms to handle heavy loads safely and smoothly.
Key Benefits
Strong drive system
Smooth tray movement
Reduced mechanical wear
Long operational life
Because these furnaces operate continuously, durability is critical. We build every mechanism to withstand demanding industrial conditions.
Uniform Temperature and Protective Atmosphere
Unlike systems that rely on agitation, we use controlled recirculation.
Advantages of Recirculation
Uniform temperature distribution
Even protective atmosphere flow
Consistent case depth
Reliable hardness levels
Uniform heating leads to uniform results. That is how we ensure repeatability in every production batch.
Safety and Ease of Operation
Safety and reliability are built into every Pusher Type Furnace we deliver.
High Operational Safety
We include:
Fail-safe control systems
Emergency interlocks
Automated monitoring
Controlled gas management
Easy Maintenance
Accessible components
Simplified controls
Long service intervals
We design our furnaces so operators can run them with confidence and minimal downtime.
