For kilns and other high temperature enclosures the wire gauge type length coil dimensions and voltage applied need to be.
Nichrome wire red hot temperature.
Nichrome is wound in coils to a certain electrical resistance and current is passed through it to produce heat.
If the thermal resistance of a wire is a constant across temperature then the temperature rise of the wire should be a linear function of the power dissipated as per the formula.
Use this online nichrome wire calculator to calculate resistance power current and voltage of the nichrome coil by just providing the length thickness and temperature of the nicr.
By the time you reached 1400f 760c enclosure air temperature the wire temperature would be 1400f plus the difference of 1130f or 2530f.
Where λ max is the wavelength at which the curve peaks and t is the temperature at which the object would emit radiation.
Nichrome wire has high tensile strength and a high melting point.
As the temperature is increasing the acme of the distribution move towards short wavelength.

The wire would melt.
This obeys wien s displacement law.
The nichrome wire was embedded in fiberglass insulation which was used to ensure that the outside temperature would have a more limited influence on the measurement gained from the thermocouple.
This way the temperature of the wire will not be constant in time but will change depending on the air temperature and movement materials that are in contact with the wire and so on.
It the wire would just be turning red at that temperature.
Nichrome wire nicr is the optimal cutting wire choice for foam cutting equipment for a variety of reasons but particularly because it is resistant against corrosion and oxidation at very high temperature.
How the heat is dissipated.
Nichrome wire when heated to red hot temperatures develops an outer layer of chromium oxide which is thermodynamically stable in air is mostly impervious to oxygen and protects the heating element from further oxidation.
The nichrome cutting wire reaches the temperature of a few hundred celcius degrees in few seconds.
δt p θ but i used the data from several nichrome wire data sheets to plot θ for a 1 foot long wire.
