Product Description

TANKII A1 Similar Grade Tk1  Fecral Alloys Wires Heating Resistance Alloy RESISTOHM 145 / ALLOY 875​

TK1 large-sized cold-drawn wire products can be used for high-temperature resistance furnace. Practice has

proved that: the product process is stable, integrated performance is good. Has good high temperature oxidation

resistance and longer service life; excellent winding properties at room temperature processing, ease of

processing molding; little rebound resilience and so on. Processing performance is very good; operating

temperature can reach 1400 .

 

TK1 is a ferritic alloy of the FeCrAl family, which can be used up to 1300°C in case of big diameters.To maintain TK1 under 1000°C during 7 to 8 hours in an oxidizing atmosphere with an unsufficient quantity of oxygen or air induces
formation of a white-grey aluminium coat of oxydewhich protects the wire of a possible chemical attack. It is recommended to oxyde the wire of this way when the element must operate in reducting conditions. This is why TK1 is generally supplied preoxidised.
TK1 can be used for resistances in electric furnaces for ceramic, chemical and metallurgic industries, and for all applications where
it is necessary to apply very high temperature of use. Life time of TK1 is better than those of NiCr in case of atmospheres containing sulfur and particularly if they are oxidizing.Life time of TK1 is particularly influenced by the formation of oxide coat. If the atmosphere
does not permit it, life time in high temperatures is considerably reduced. Prejudicial atmospheres are nitrogen, ammonia, and hydrocarbons

User Manual

 

  • 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.
