The electric heating tube has the characteristics of high mechanical strength, high thermal efficiency, safety and reliability, simple installation and long service life. Compared with other heaters, the electric heating tube is more cost-effective, convenient to use, and pollution-free. It is widely used in various heating fields, such as saltpeter tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, air heating furnaces, and drying Furnace, drying oven, hot pressing mold, medical, aviation, catering, chemical industry, electronics, injection molding, etc.
What are the advantages of electric heating tubes in the heating field?
(1) Moderate one-time investment and low maintenance cost.
(2) Electric heating is clean and hygienic, no soot, no oil, safe and environmentally friendly.
(3) The thermal inertia is small, the temperature control precision is high, and the heating effect is good.
(4) The electric heating power is convenient to adjust, easy to adjust the temperature, and realize automatic control.
(5) The electric heating method may generate a large amount of heat energy in a small range, so it can be heated at a high speed to reach a predetermined temperature.
(6) There is no need for ambient atmosphere, unlike burning fuel, which depends on oxygen, so the heated objects are not easy to oxidize.
(7) High thermal efficiency. Compared with other energy sources, the thermal efficiency of coal is about 12%-20%, liquid fuel is about 20%-40%, gas fuel is about 50%-60%, steam is about 45%-60%, and electricity is about 50%. %-95%.
(8) The object to be heated can easily move the machine automatically in the heating zone, which creates extremely favorable conditions for the application of electric heating in production lines and automated production lines.
The above is an introduction to the advantages of electric heating tubes in the heating field.
