THERMOXYTIP contains a well-established solid electrolyte and a solid-state reference material encapsulated in a quartz tube to form the Oxygen sensor in a modular form. This sensor together with the Oxygen activity in the steels form a millivolt cell and generates an e.m.f. Proportional to the amount of dissolved Oxygen in the molten steel bath. 

A high melting point virgin metal rod forms the bath electrode making contact with the molten metal thus completing the electric circuit. The well-known THERMOTIP brand Disposable Thermocouple forms the companion bath temperature sensor. 

Multivarious uses of THERMOXYTIP:

The carbon content in steel can be estimated under certain circumstances. When the Carbon and the Oxygen reaction has reached an equilibrium this may be expressed by the relation:M=(% C) (%O) = 0.0022Thus with an indicated oxygen content of say 300 ppm, the carbon content can be estimated to be 0.073 %.Since Silicon and Oxygen diffuse very rapidly at liquid steel temperature, the equilibrium of the reaction Si + 2 O = SiO2 is achieved very quickly and % Si can be estimated by the equation.Log % Si = 20, 166 E/T - 12530/T + 2.78Where E = Oxy probe output voltsT = Temperature in Degrees KelvinIn case of low carbon Aluminum killed argon stirred steels (LCAK), the residual aluminum can be determined.
