Quantitative Spectrochemical Analysis of a Molten Metal Bath

The method and apparatus comprises direct reading spectrometers for rapid quantitative spectrochemical analysis of a molten metal bath.

Apparatus 4 is pushed through the layer of slag 3 and immersed within molten bath 2 at a point where an analysis of metal is representative for that of the whole bath. Apparatus 4 comprises inner and outer tubular members 11 and 12, which together define an annular cooling chamber 13. Cooling fluid is conveyed into chamber 13 through input 20 and removed through output 21. Positioned within inner member 11 is tubular spectroanalytical electrode 30 and its associated socket 31 of electrically nonconducting material. Centrally disposed opening 33 coincides with tubular cavity 34 of electrode 30. Fastened to the bottom portion of member 31 is annular electrically conducting member 35 providing electrical contact between lead 9 and electrode 30. For the observation of discharge 36 through opening 33 and cavity 34 there is the fiber optic 7 which is held in position by plug 37. Extending around plug 37 there is cylindrical cavity 41 which serves to convey the gas received through conduit 28. The interior of member 11 is pressurized via gas conduit 10 so that molten metal 2 is prevented from rising above a certain level to avoid damage to electrode 30. An error signal for control of the level discharge current or light intensity of any chosen spectral emission line is used.
