Double-control + automatic proofing building materials
non-combustible test furnace
Scope of application:
The test furnace is developed in accordance with the technical
indicators and requirements specified in the national standard
GB/T5464-2010. It is applicable to the specified test method for
evaluating the combustion performance of building materials under
laboratory conditions, and suitable for testing the combustion
performance grade of Class A fireproof materials in the GB8624
combustion performance grading of building materials.
Product function characteristics:
1.Dual Control Mode: Operable via touch screen or computer with
easy mode switching. One device supports simultaneous operation of
multiple computers for LAN sharing (user provides computer &
printer; upper computer software, router, and network cable
included with equipment).
2.Automatic Sample Handling: Features auto-release function to
insert samples into the furnace after temperature stabilization.
The sample basket rotates 90° automatically post-test for sample
replacement. The process can be paused at any time, and the basket
returns to the initial position.
3.Temperature Control: Employs microcomputer and silicon controlled
technologies to adjust furnace body temperature via power
regulation.
4.High Automation: Displays and records furnace surface
temperature, sample center temperature, and real-time data during
testing, with automatic operation prompts for each test step.
5.Historical Data & Temperature Balance: Queryable historical
curves for automatic temperature balance judgment.
6.Safety & Usability: Safe, reliable test process with
user-friendly operation.
7.Refractory Furnace: Custom-molded refractory furnace with
excellent heat insulation performance.
8.Heating System: High-quality bar heaters enable furnace
temperature to reach 900℃.
9.Software Control: PLC + NAbview professional software displays
real-time curves of in-furnace temperature, sample center
temperature, and sample surface temperature, supporting
auto-control, data collection/processing, storage, and result
output.
10.Observation Mirror: Top-mounted mirror for visualizing sample
combustion in the furnace.
11.Thermocouples: Installed in-furnace thermocouple, sample center
thermocouple, and sample surface thermocouple.
12.Thermocouple Scanner: 360° rotatable and liftable for precise
positioning.
13.Air Stabilizer & Shield: Stainless steel inverted conical
air stabilizer and cylinder guide shield.
