Heat Soak Furnace (Fangding)

Categories: Glass Machinery, Machinery

Product Specification

Core Function:

Reduces the risk of spontaneous breakage in tempered glass caused by Nickel Sulfide (NiS) inclusions by controlled heating and soaking.

Key Features:

Uniform Heating System:
- Finned heating tubes (often located at the top).
- Individual high power heating tubes (e.g., 6kW per tube).
- PID control for accurate temperature management.
- SSR (Solid State Relay) temperature control modules for precise temperature jumps (e.g., within ±3°C per minute at a single point).
Forced Hot Air Circulation: Ensures even temperature distribution within the furnace.
Precise Temperature Control:
- Intelligent control systems with HMI for easy operation.
- Multiple temperature monitoring points (thermocouples) on the glass surface and within the furnace (e.g., 16-21 points).
Computer Process Control System:
- Multi-temperature curve display.
- Real-time temperature monitoring.
- Customer information storage.
- Data recording (temperature curves stored frequently, e.g., every minute).
Adjustable Holding Time: Typically adjustable from 1 to 8 hours.
Safety Features: Complete safety programs and failure alarm functions.
Good Heat Preservation: Often features stainless steel lining and significant thermal insulation (e.g., 100mm) with seamless welding to minimize heat loss.
Air Duct Thermal Cycle: Unique air duct designs for efficient and stable heating.
Optional Features:
- WiFi remote monitoring.
- One-button printing for reports.
- Customizable sizes.
- Automatic glass loading and unloading systems in some production lines.
