  • Apparatus to indicate the oxygen content of molten copper using the vibration signal of a graphite rod immersed into the molten metal
    Patent number: 5405121
    Abstract: The purpose of this invention is to present an apparatus consisting of a graphite rod, a vibration signal sensor, a signal processing unit, a data processing unit, and a data display unit to indicate the oxygen content of a copper melt. As such graphite rod is immersed into the molten metal it vibrates and the level of vibration is statistically correlated to the level of dissolved oxygen in the copper melt.
