What are the requirements of the graphite electric heating plate for the electric heating ring? Graphite electric heating plate is a device that uses electric heating alloy wire as heating material, mica soft plate as insulating material, and is outsourced with thin metal plate (aluminum plate, stainless steel plate, etc.
) for heating
.

Applications such as electric hot water bottles
.

The metal tubular electric heating element is cast in the aluminum plate, aluminum plate or welded or embedded on the aluminum plate and aluminum plate to form various shapes of electric heating plate and electric heating
.

Applications such as rice cookers, electric irons, electric coffee makers,
etc.

The requirements of the graphite electric heating plate for the electric heating ring are: (1) Long service life
.

It is required that it can be used safely for more than ten years under normal use and proper storage; the accumulative power-on use time (life test: power-off 1h, power-on 2h) should be more than (2000h)
.

(2) High thermal efficiency and low power consumption
.

There is a gradual trend to increase the electric power of the electric hot plate in order to reduce the mass of the heat storage body, so as to achieve the purpose of increasing the power without increasing the electricity consumption
.

If the power is high and the heat storage body is small, the thermal inertia is small, so the heating is fast, the cooking or heating speed is fast, and the thermal efficiency is also high, and the electric energy consumed by the user is reduced instead
.

For a production plant, a smaller heat reservoir means lower costs
.

 　　(3) The temperature is adjustable
.

The surface temperature of the electric heating plate should be able to adapt to the requirements of various operating temperatures
.

For example, boiling and boiling cooking require a temperature of 100°C, while frying cooking requires a temperature of 140-180°C
.

If it is too low, it will not meet the requirement of frying the food to brown, and if it is too high, the cooking oil will be easily carbonized.
Therefore, the temperature of the plate surface should be adjusted within the range of 120-350 °C
.

 　　(4) Easy to clean and better anti-abrasion performance
.

 　　Matters needing attention for graphite heating plate: 1.
The contact surface where the heating element is installed should be flat and free of unevenness
.

 　　2.
The electric heating element should be kept dry and avoid soaking in water to affect its insulation performance
.

 　　3.
When installing, first check whether the installation position is consistent with the specifications of the electric heating element, and whether the voltage used is consistent
.

 　　4.
After installation, check whether the hexagon socket bolts, wiring seat bolts and wiring bolts are locked, so as to avoid thermal expansion and cold contraction affecting the life of the product
.

 　　The above is an introduction to the requirements of the graphite electric heating plate for the electric heating ring.
I believe that everyone has a corresponding understanding of this after reading, and I hope it will be helpful to everyone
