Building materials noncombustible test furnace
Scope of application
The test furnace is developed according to the technical indicators
and requirements specified in the national standard GB/T5464-2010.
It is applicable to the test method for assessing the combustion
performance of building materials under laboratory conditions and
to test the combustion performance grade of grade A fire proof
materials in the GB8624 combustion performance grade of building
materials.
Product function characteristics
1. Microcomputer technology and silicon controllable technology are
used to adjust the furnace body temperature through power.
2. Double control mode: the operation can be controlled on the
touch screen, or on the computer, and the operation mode can be
easily switched;One device can operate several computers at the
same time, but several computers online at the same time, can
realize LAN sharing; (users bring their own computer, printer;
upper computer software, router, network cable we will issue with
the equipment).
3. High degree of automation, show and record the surface
temperature of the furnace, sample center and sample during the
test, and the test steps will automatically jump out of the
operation prompt.
4. The historical curve can be queried to automatically judge the
temperature balance.
5. The test process is safe and reliable and convenient for
operation.
6. Custom version of the mold forming refractory furnace, good heat
insulation performance.
7. Using high-quality bar heaters, the furnace temperatures can
rise to 900℃.
8. PLC+NAbview professional software displays the in-furnace
temperature, sample center temperature and sample surface
temperature curve in real time, which can realize automatic
control, data collection and processing, data preservation and
output measurement results.
9. The top is equipped with an observation mirror to facilitate the
user to observe the combustion state of the sample in the furnace.
10. Resettlement thermocouple, sample center thermocouple, sample
surface thermocouple in the furnace;
11.Thermocouple scanner with 360 degrees rotatable and lifting.
12.Stainless steel inverted conical air stabilizer and cylinder
guide shield.
13.The software automatically controls the heating rate and
controls the furnace body temperature in stages.
14.In the software, the current regression judgment temperature
balance conditions are included.
