User Manual

1.Rated Voltage: 220V/380V

2. The installation process to avoid knocking, to avoid the damp, hand-held stove wire, they should wear gloves. Wire should be installed after the furnace has remained flat, and prevent surface scratches, dirt, corrosion, or improper installation, by affecting the life of

3. In the rated voltage to use. In strong reducing atmosphere, acid atmosphere, an atmosphere of high humidity will affect the use of life;

4.Temperature before use should be in dry non-corrosive atmosphere, about 1000 ºC spend a few hours, so that furnace wire protective film formed on the surface after normal use, so that can guarantee the normal life of furnace wire;

5.Furnace installation should ensure that the insulated wire good power to avoid touching furnace after the wire, guard against electric shock or burns.


1Cr13Al4, 0Cr25Al5, 0Cr23Al5, 0Cr21Al6, 0Cr21Al4, 0Cr21Al6Nb, 0Cr27Al7Mo2 is one kind of normal material of Fe-Cr-Al alloy.
FeCrAl alloy has the characteristic of high resistivity,low temperature resistance coefficient,high operating temperature,goodanti-oxidation and anti-corrosion under high temperature.
It is widely used in industrial furnace, household appliances, industry furnace, metallurgy, machinery, aircraft, automotive,
and other industries producing heating elements and resistance elements.
