  • Method of producing thin cast sheet through continuous casting
    Patent number: 5697425
    Abstract: Thin cast sheets having an excellent quality are obtained by continuous casting in which a semi-solidified metal slurry is fed from a continuous production device of the semi-solidified metal slurry through a discharge nozzle provided with means for heating the nozzle itself into a twin roll type continuous strip caster, at where the slurry is rapidly quenched and solidified to fine a structure and dispersion of precipitate.

  • Reference electrode for oxygen probe
    Patent number: 4399022
    Abstract: In the reference electrode for the oxygen probe comprising a mixture of Cr powder and Cr.sub.2 O.sub.3 powder, an improved reference electrode characterized in that Cr powder and Cr.sub.2 O.sub.3 powder are mixed in a ratio 97%:3% to 80%:20% and the mixture is sintered beforehand. An oxygen probe using this electrode exhibits improved response, stability and reproducibility in molten steel.
