About heat-treated products
When heat-treated in an electric furnace, the physical properties may change depending on the object,
which may cause a danger to the surroundings and may adversely affect the electric furnace itself.
Please read the following carefully.
Do not process substances that generate explosive gas by heat treatment
with this machine. Explosion may result in death, injury or fire.
Take treatment beforehand to prevent the generation of explosive gases.
●
A large amount of carbon is generated by heat treatment. Heat treat resin, etc. as little
as possible. Also, if the inside of the furnace is black, carbon may be attached, so please
be careful to muffle firing with unloaded at 800
℃
for about 1 hour. If the heat treatment
is continued with the carbon still attached, the heater may break.
●
The heat treatment may damage the furnace heat insulator, heater, hearth plate, sheet
metal, and deodorizer due to the gas or liquid generated from the substance.
When performing heat treatment, thoroughly check the material.
●
If the processed material and the heat insulating material are in contact with each other,
they may react with each other and fuse together, or the heater may break.
・
If the product has not been used for a long time, the heat insulating material will absorb moisture,
so it is recommended to bake it (800C for about 1 hour) before use.
■
Insulation material
●
The heat generator of this machine uses lightweight insulation to improve the thermal
efficiency and temperature distribution. For this reason, if the processed product
contacts the hot plate, it may be damaged, so be careful not to contact the left and right
hot plates when putting in or taking out the processed product. Also, depending on the
type of gas or liquid generated from the heat-treated material, damage to the heat
insulating material or breakage of the heater may occur, so please check in advance.

●
If the inside of the furnace is at a high temperature of 600
℃
or higher and the door is
opened for rapid cooling, the insulation may be damaged.
※
There may be cracks on the surface of the heat insulation material of the furnace body at the time
of purchase or after several temperature rises, but there is no problem with performance and quality.

Regular operating temperature and maximum operating temperature
・
Regular operating temperature
It is specified as a temperature that can withstand long-term use when there is no corrosive gas from
the heat-treated product. Therefore, if corrosive gas, liquid, etc. are generated by heat treatment, the
furnace is damaged in a relatively short period of time even if it is used at a normal operating
temperature or a lower temperature. It is possible that the heater will break or the furnace insulation
will be adversely affected.
・
Maximum operating temperature
For a relatively short time (several hours), the temperature is set so that it can be used in the absence
of corrosive gas. Therefore, it is not suitable for long-term use.
