Abstract
An apparatus for detecting the condition of the flow of liquid metal in or from a teeming vessel includes a sensor for detecting vibration caused by a flow of liquid metal in or from the teeming vessel and for outputting a sensor signal corresponding to an amount of vibration detected by the sensor. A signal processor receives the sensor signal and compares the sensor signal to a reference signal and outputs a comparison signal. A logic unit receives the comparison signal and outputs a status signal indicative of the condition of the flow of the liquid metal in or from the teeming vessel.
Claims28
An apparatus for detecting the condition of the flow of liquid metal in or from a teeming vessel comprising:
- a sensor for measuring a desired flow condition of liquid metal flowing from a teeming vessel to output a reference signal corresponding to the desired flow condition, and for monitoring the status of the flow condition of the liquid metal flowing from the teeming vessel to output a sensor signal corresponding to the status of the flow condition;
- a signal processor for comparing the sensor signal to the reference signal and outputting a comparison signal;
- and
- a logic unit for receiving the comparison signal and for outputting a status signal indicative of the condition of the flow of the liquid metal in or from the teeming vessel.
A method for detecting a condition of a liquid metal flow in or from a teeming vessel, the method comprising the steps of:
- flowing liquid metal from a teeming vessel;
- measuring a desired flow condition of the liquid metal flowing from the teeming vessel;
- converting the desired flow condition to a reference signal;
- monitoring the status of the flow condition of the liquid metal flowing from the teeming vessel;
- converting the status of the flow condition to a sensor signal;
- comparing the sensor signal to the reference signal to output a comparison signal;
- and
- outputting a status signal in response to the comparison signal, the status signal being indicative of a condition of the flow of the liquid metal in or from the teeming vessel.
