Best Price Chamber Heating Furnace/Electric Box Kiln for Ceramic Sintering
Our box type furnaces are the most cost effective high temperature muffle furnace. The furnace consists of high quality alumina fiber brick and MoSi2 heating elements with special design, and furnace temperature is controlled by high precision SCR (Silicon Controlled Rectifier) digital controller with accuracy ±1°C and 51 segments programmable. It is an ideal tool for materials annealing and sintering in your research laboratory.
1.Muffle Furnace Specification
51segments programmable and PID auto control
Alumina Ceramic fiber board
Double shell with fan cooling
2. Product’s structure and advantage
The fireproof layer consists of lightweight ceramic fiber, the inside heat resistant steel infixed
shape, the outer aluminum silicate fiber insulation layer; fireproof layer and insulating layer of
200 mm, total thickness for electric furnace provides excellent heating preservation effect.
The chamber structure can be resistant to thermal shock; it is suitable for the electric furnace
need high temperature to open the door. Under high temperate condition frequently open the
door, the chamber does not deformation and cracking, the furnace is durable, and there is no
danger of collapse. All fiber chamber greatly reduces the weight of the furnace. Due to the
smaller fiber lining heat storage coefficient of thermal conductivity is only 0.8. Compared with
the traditional refractory furnace, its heating rate faster, energy-saving effect is remarkable
2) Three surface heating, thermal radiation, to form a uniform temperature field in the chamber,
the temperature uniformity of ±5 C. To avoid uneven temperature field caused by annealing
workpiece defects crack, annealing inconsistent
3) Furnace structure:
double shell with fan cooling, built-in fan and air duct, to ensure the furnace structure surface
temperature is lower than 60 degrees.
3. Temperature’s profile for your reference as below.( for example: 6 segments)
Compared with the ordinary iron chromium aluminum wire resistance, higher temperature and more durable
Using high temperature, anti-oxidation, corrosion resistance, long life, small deformation, easy installation and maintenance.
Suitable for ultra high temperature heating, long service life, high calorific value and economic price
5. Trouble shooting for typical Problems
Open Power Lock, no power
Fuse (4A) in control panel is broken
Check control panel, and replace
Green Power indictor is off,
but Red open circuit indicator
Fuse ( 50A) in main power
circuit is broken
Open the cover of front panel
and replace the fuse
No current shows in meter , but
has Max. Voltage
Heating element broken
Find broken heating rod, and
Controller display panel
SV shows“ OraL”
Thermal Couples broken
Replace Thermal couples ( B type )
Controller display panel
SV shows“ HI AL”
Furnace temperature >
1700C, Protection from Alarm
Cool furnace down, and find
reason why temperature is so high
( program setting may be wrong)
Power and heating element are OK, but furnace can’t be
controlled by program.
Controller or related circuit may be damaged
Program running, but furnace can not be heated,
or real temperature is far behind the setting value
oPL or oPH value is too low
due to local voltage lower or frenquency different
Incraese “oPL” and “oPH” value till
current meter shows “ 120 A – 140A”, and program runs smoothly
During heating below 300C, the temperature value ( PV) is not stable, and doesn’t match with setting program (SV)
It is normal because the furnace comes with a high temperature thermocouple, which is not sensitive at temperature below 300C
Don’t worry. Let the furnace heat to
300C, then thermocouple will functionstably with program. If the PV value at 300C is still less than that of SV, you may need to increase OPL value a little.
