Further, oxygen was assumed to behave as an ideal Henrian solute in liquid iron. These assumptions were probably necessitated by the nonavailability of published values of the interaction parameters between oxygen and other solutes in liquid iron. However, some workers[ 18 , 19 ] persisted with these assumptions even after Sigworth and Elliott,[ 20 ] in , published a compilation of the interaction parameters between most solutes of importance in steelmaking. However, Deo and Boom observed that this nonstoichiometry is of negligible significance in steelmaking operations. This convention has been followed up on in the present work. Experimentation Simultaneous distribution of phosphorus and oxygen between liquid steel and slag was recently measured by the present authors.

In this model the charges are adsorbed on the electrode and are rigidly fixed there by the presence of an immobile layer of oppo- sitely charged ions in the electrolyte.

Further into the elec- trolyte there is a diffuse layer of charge which may have a sign either the same or opposite to that of the absorbed layer. Only the diffuse layer is free to move under the influence of an applied potential.

Principles of Infrared Thermocouples - Omega. Tough transient hot wire method had been considered to have high accuracy as reported by many researchers; it maybe easy to be affected by the leakage of electric current from the hot wire to liquid.

In the present work water cooling tube method was adopted to measure the thermal conductivity of solid fluoride slag using electroslag metallurgy process.

Experimental Measurement of effective thermal conductivity of fluoride slag was performed by water cooling tube method. The theoretical principle is based on the Single cylinder wall heat transfer model. Figure 1 is the schematic diagram of the measurement apparatus.

Details of this apparatus and the basic principle of the method had also been reported in previous work. It would have a large radial temperature gradient in the crucible.

In order to measure crust temperature, another three series of thermocouple have been adopted in the crucible. These thermocouples have been proofed before the experiment.
