Flat Radiation Furnace

Proven Radiant Heating Technology Engineered for Stability, Uniformity & Long-Term Reliability

The Flat Radiation Furnace represents the classical core of glass tempering technology. When engineered with precision, material science, and advanced control logic, radiation furnaces continue to deliver highly stable, repeatable, and cost-efficient tempering performance for a wide range of flat glass applications.

At Wings Logic, our flat radiation furnaces are not basic heating chambers. They are thermally optimized systems, refined through heat transfer research, chamber design optimization, and decades of industrial production feedback. This furnace type remains essential where:

Flat clear and tinted glass dominates production
High throughput and reliability are critical
Energy efficiency and maintenance simplicity matter
Optical stability is a priority

Understanding Radiation Tempering Technology

In a radiation furnace, glass is heated primarily through radiant heat transfer generated by electric heating elements installed in the furnace chamber.
Unlike convection furnaces, where heat is actively forced by air movement, radiation furnaces rely on:

When properly engineered, radiation furnaces offer:

Wings Logic focuses on perfecting radiation uniformity, which is the true challenge of this technology.

Core Engineering Philosophy at Wings Logic

Our flat radiation furnace design is guided by four core principles:

Radiation furnaces succeed when thermal balance is mastered, not when power is simply increased.

Furnace Chamber & Structural Design

High-Rigidity Furnace Frame

The furnace body is constructed using heavy-duty structural steel, designed to maintain dimensional stability under continuous high-temperature operation.

Key structural objectives:

Resistance to long-term thermal expansion
Mechanical stability for roller alignment
Protection against vibration and deformation

Structural rigidity directly influences glass flatness and optical quality.

Optimized Internal Chamber Geometry

The internal chamber layout is carefully designed to:

Ensure uniform radiation exposure
Minimize thermal shadow zones
Maintain consistent heat distribution from edge to center

This geometry is validated through thermal profiling and production testing, not guesswork.

Heating Element Technology & Layout

High-Quality Electric Heating Elements

Wings Logic radiation furnaces use industrial-grade heating elements designed for:

High temperature stability
Long service life
Consistent radiant output

Element material selection and placement are critical to prevent:

Local overheating
Temperature gradients
Uneven glass softening

Multi-Zone Heating Architecture

The furnace is divided into multiple independent heating zones, each controlled separately. This enables:

Edge and center temperature balancing
Fine tuning for different glass sizes
Compensation for heat loss at boundaries

Each zone operates under closed-loop PID temperature control, ensuring stable heating conditions.

Radiant Heat Transfer Control

Controlled Infrared Exposure

Radiant heat penetrates glass from the surface inward. Wings Logic furnaces control:

Radiation intensity
Exposure duration
Zone-to-zone balance

This ensures:

Uniform glass temperature
Controlled softening
Stable stress formation during quenching

The goal is thermal equilibrium, not aggressive heating.

Ceramic Roller Transport System

Precision Ceramic Rollers

Glass moves through the furnace on high-temperature ceramic rollers, engineered for:

Dimensional stability
Smooth rotation
Minimal thermal distortion

Roller quality directly affects:

Roller wave
Surface distortion
Edge stress consistency

Wings Logic uses strict roller straightness and alignment standards.

Conveyor Speed & Process Stability

Roller speed is synchronized with:

Heating time requirements
Glass thickness
Furnace load conditions

Stable transport ensures uniform radiant exposure and consistent heating cycles.

Quenching System – Converting Heat into Strength

Rapid Controlled Cooling

Once heated, glass enters the quench section, where high-pressure air jets rapidly cool the surfaces. This creates:

Surface compression
Internal tensile stress
Increased mechanical strength

Radiation furnaces require precisely balanced quenching, as heating is gentler than convection systems.

Balanced Quench Air Engineering

Wings Logic quench systems feature:

Top & bottom independent pressure control
Uniform nozzle distribution
Adjustable air flow parameters

This allows control over:

Stress depth
Fragmentation pattern
Optical quality

Proper quenching transforms controlled heat into safe, reliable tempered glass.

Optical Quality & Flatness Control

Radiation furnaces are known for their ability to produce excellent flatness when properly designed.

Wings Logic flat radiation furnaces minimize:

Roller wave
Surface distortion
Visual anisotropy
Edge deformation

This makes them especially suitable for:

Furniture glass
Interior glass
Flat architectural applications
Standard safety glazing

Intelligent Control Software

Recipe-Based Heating Logic

The furnace control system supports:

Predefined heating recipes
Thickness-based parameter selection
Zone temperature coordination

This ensures:

Repeatable results
Reduced operator dependency

Real-Time Monitoring & Protection

Sensors continuously monitor:

Zone temperatures
Roller movement
System stability

Automatic protection logic prevents:

Overheating
Element damage
Process instability
