Insulation Board Tunnel Furnace
Category：Tunnel Oven Production Line
Introduction
The insulation board tunnel furnace is a high-efficiency thermal equipment specially designed for continuous drying, curing, and heat treatment in industrial-scale production.The equipment adopts a continuous tunnel structure combined with a precise multi-zone independent temperature control system to achieve automated and uniform heating of materials. The furnace body extensively uses new high-quality composite insulation materials to significantly reduce heat loss. It is specially designed for the continuous drying and curing production of various exterior wall insulation boards, foam concrete boards, rock wool boards, and new building materials.
Applications
Building Material Curing:
Used for heating and curing new building materials such as expanded polystyrene particle insulation boards and extruded polystyrene boards (XPS).
Moisture Drying:
Used for rapidly removing excess moisture during the production process of foamed cement insulation boards and calcium silicate boards.
Coating Drying:
Used for continuous drying of surface coatings such as natural stone paint and fluorocarbon paint on integrated insulation and decoration boards.
Composite Bonding:
Used for thermal pressing or thermal activation drying of adhesives during the composite process of multi-layer insulation materials.

Features
High Efficiency and Energy Saving:
The equipment adopts a thick high-quality rock wool insulation layer combined with a unique airflow circulation design, reducing energy consumption by more than 30% compared with traditional ovens.
Precise Temperature Control:
Uses PID microcomputer intelligent temperature control combined with SSR solid-state relays, allowing independent control of each temperature zone.
Uniform Heating:
The powerful air circulation system enables bidirectional hot air circulation inside the furnace, ensuring consistent heating of both the surface and core of the boards.
Stable Operation:
The heavy-duty conveying structure combined with variable frequency speed regulation ensures smooth operation without vibration, preventing deformation of the boards.
Safety and Explosion Protection:
Equipped with over-temperature alarms, automatic power cutoff systems, and independent moisture exhaust and explosion-proof systems to ensure safer production.
