The manufacturers of heat conduction oil and electricity heaters introduce the classification and characteristics of electric hot wire

We know that the electric hot wire is the original part of the thermal energy conversion, and it is the core of the heating tube. The underneath the small editor in detail will give you a specific introduction to the relevant knowledge of electric hot wire. The outer tube center line is spiral and evenly coiled in the outer tube.

The quality of the electric heating wire directly affects the service life and the performance of the electric heating pipe material, thermal oil electric heater it can be divided into iron chromium aluminum and nickel wire.

Fe Cr al good corrosion resistance at high temperature, especially suitable for use in containing sulfur and sulfide in the atmosphere, and the price is low, is the heating material of industrial furnace, household appliances, infrared device ideal. The most commonly used brand is 0Cr25AL5.

The characteristics of Kanthal wire material is:

The use of high temperature, such as maximum temperature up to HRE Fe Cr alloy wire in the atmosphere at 1400 DEG c;

The allowable surface load is large;

The oxidation resistance is good, and the oxidation of AI2O3 film after oxidation has good resistance to chemical resistance and high resistivity.

The proportion of nickel chromium alloy is less than that of nickel chromium alloy.

The resistivity is high.

Good sulfur resistance;

The price is obviously lower than nickel chromium alloy.

The disadvantage is that as the temperature rises, the performance is plastic, and the strength at high temperature is low.

Nickel chromium wire has high strength under high temperature, has good processability and solderability. It is widely used in metallurgy, household appliances, machinery manufacturing, heating materials and electrical industry. Long service life, but because of nickel, so the price is higher.

The characteristics of nickel chromium resistance wire are:

The strength at high temperature is high.

The material will not become brittle after a long period of use.

Nickel aluminum alloy fully oxidized the radiation ratio of Fe Cr Aluminum Alloy high;

No magnetic;

In addition to the sulfur atmosphere, it has good corrosion resistance.

The defects of alloy wire are the most widely used but also the disadvantages of the alloy wire. Its disadvantage is the state itself in a very high temperature (hot state), easily in the air oxidation and burn off; to analysis from the aspect of electric energy conversion, due to visible light and make the energy loss; the resistance wire is often used in a spiral state, electricity will be generated when the inductive effect.
