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.

 2. Product’s structure and advantage

  1) Chamber:

 

     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.

Fe-Cr-Al-Mo wire

Compared with the ordinary iron chromium aluminum wire resistance, higher temperature and more durable

W T≤1400C

 

SiC heater

Using high temperature, anti-oxidation, corrosion resistance, long life, small deformation, easy installation and maintenance.

W T≤1750C

  

MoSi2 heater

Suitable for ultra high temperature heating, long service life, high calorific value and economic price

 

 5. Trouble shooting for typical Problems

 

Problems

Reason

Solution

  Open Power Lock, no power

   indication

  Fuse (4A) in control panel is broken

  Check control panel, and replace  

  fuse

  Green Power indictor is off,

   but Red open circuit indicator

   is On

   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

  replace it

  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

  Heck controller.

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.
