  • Determining a presence or absence of water in a DC casting starter block : method and direct chill apparatus claims
    Patent number: 11255712
    Abstract: A method to determine a presence or absence of water in a cavity of a starter block having a non-horizontal surface of DC casting equipment including emitting a wave using a device containing a sensor, the wave propagating along a virtual beam path, directing the wave towards the cavity of the starter block such that the wave is reflected on a horizontal surface of the water, if water is present in the cavity, or is reflected on a non-horizontal surface of the cavity of the starter block, if no water is present in the cavity, detecting the reflected wave using the sensor, or not detecting the wave using the sensor, determining that there is water present in the cavity if the sensor detects the reflected wave, and determining that water is absent in the cavity if the sensor does not detect the wave while the sensor emits the wave.
