HRE resistance heating wire

Short Description:

HRE resistance heating wire is used for high-temperature furnace. Its characteristics are: high temperature resisting, long operating life, good oxidation resistance, excellent entanglement at room temperature, good process ability, back to the flexibility of small, and its processing performance is better than 0Cr27Al7Mo2 and high temperature performance is batter than 0Cr21Al6Nb, the use of the temperature can resch 1400℃.

Helping

1.  Rated voltage: 220V/380V

2.  The installation process to avoid bump, to avoid the tainted dirt, to avoid damp, to wear gloves when you are hand-held wire. After installation furnace wire should remain straight, to prevent surface scratches and erosion by dirt, so affect the useful life and improper installation;

3. When you use at rated voltage. In strong reducing atmosphere, acid atmosphere, moist atmosphere will affect the service life of high temperature use;

4.  You use before the high temperature, should to stay a few hours and be free from corrosion in the dry atmosphere of about 1000 ℃, so that wire furnace after the protective film formed on the surface of normal use, that can guarantee the life of the normal wire heater;

5.  The installation process should keep heater wire insulation installation, at power to avoid touching, to guard against electric shock or scald.
