HV220 7.10g/Cm3 Ceramic Kilns FeCrAl Heating Wire

High-temperature Heating FeCrAl APM / TK-APM 216YZ Iron Chromium Aluminum Alloy Wire for ceramic kilns

TK-APM 216YZ Iron Chromium Aluminum Alloy takes refined master alloy as raw material, uses powder metallurgy technology to manufacture alloy ingots, and is manufactured by special cold and hot processing and heat treatment process. The product has the advantages of strong oxidation resistance, good corrosion resistance at high temperature, small creep of electrothermal components, long servicelife at high temperature and small change of resistance. It is suitable for high temperature 1420℃,high power density, corrosive atmosphere, carbon atmosphere and other working environments. It can be used in ceramic kilns, high temperature heat treatment furnaces, laboratory furnaces,electronic industrial furnaces and diffusion furnaces.

Noted:Testing according to GB/T13300-91 standard method

• Rated Voltage: 220V/380V

• 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

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

• Temperature before use should be in dry non-corrosive atmosphere, about 1000 ℃ 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;

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