Abstract

Systems and methods are disclosed for an event detection system that captures data associated with events while a DC casting system forms an ingot, determines characteristics of the events, and improves the casting system based on the events. Example systems and methods may include initiating a casting operation using one or more pieces of equipment of a casting system including a casting apparatus; capturing sensor data associated with one or more acoustic signals captured relative to the one or more pieces of equipment performing the casting operation; comparing the sensor data with a set of acoustic profiles; determining whether a particular type of event has occurred; causing an adjustment to the casting system or to the casting operation based on whether the particular type of event has occurred; and initiating a second casting operation using the adjusted casting system or casting operation.

First claim

That which is claimed is:

1. A non-transitory computer readable medium comprising program code, which when executed by a processor, is configured to cause the processor to:
receive sensor data from a sensor;
compare the sensor data with a set of acoustic profiles;
determine, based on the comparison, whether a particular type of event has occurred;
determine an adjustment to a casting system or a casting operation based on whether the particular type of event has occurred; and
generate a control response for causing the adjustment to the casting system or the casting operation.

2. The non-transitory computer readable medium of claim 1 , wherein the program code, which when executed by a processor is configured to further generate, using initial acoustic signals, the set of acoustic profiles, each acoustic profile of the set of acoustic profiles being associated with a type of event associated with multiple casting operations over the initial period of time.

3. The non-transitory computer readable medium of claim 1 , wherein the program code, which when executed by a processor is configured to further update the set of acoustic profiles using the sensor data and the determination of whether the particular type of event has occurred.

4. The non-transitory computer readable medium of claim 1 , wherein the program code, which when executed by a processor is configured to further compare characteristics of acoustic signals captured relative to a casting operation to characteristics of acoustic signals captured during previous casting operations.

5. The non-transitory computer readable medium of claim 1 , wherein characteristics of the acoustic signals include one or more of frequency, pitch, loudness, or tone.

6. The non-transitory computer readable medium of claim 1 , wherein the program code, which when executed by a processor is configured to further determine a recommendation regarding whether the particular type of event has occurred and a likelihood that the particular type of event has occurred based on the sensor data.

7. The non-transitory computer readable medium of claim 1 , wherein the program code, which when executed by a processor is configured to further cause shutting off the casting system or generating a modified recipe for the casting operation.

8. The non-transitory computer readable medium of claim 1 , wherein the particular type of event includes one or more of a bleed out, a bleed over, a butt bounce, butt curl, or a water cooling operation.

9. A system for detecting events during a casting operation, the system comprising:
at least one processor; and
at least one sensor configured to sense acoustic signals from a casting operation, wherein the at least one sensor captures sensor data associated with the casting operation, wherein the at least one sensor is operably connected to the at least one processor, and wherein the at least one processor is configured to:
compare the sensor data with a set of acoustic profiles;
determine, based on the comparison, whether a particular type of event has occurred;
determine an adjustment to a casting apparatus or to the casting operation based on whether the particular type of event has occurred; and
generate a control response for implementing the adjustment.

10. The system of claim 9 , wherein the at least one sensor comprises an acoustic sensor and the acoustic sensor is configured to capture initial sensor data associated with acoustic signals from multiple casting operations over an initial period of time, and
wherein the at least one processor is further configured to:
generate, using the initial acoustic signals, the set of acoustic profiles, each acoustic profile of the set of acoustic profiles being associated with a type of event associated with the multiple casting operations over the initial period of time.

11. The system of claim 9 , wherein the at least one processor is further configured to update the set of acoustic profiles using the sensor data and the determination of whether the particular type of event has occurred.

12. The system of claim 9 , wherein the characteristics of the acoustic signals include one or more of frequency, pitch, loudness, or tone.

13. The system of claim 9 , wherein the at least one processor is further configured to determine a recommendation regarding whether the particular type of event has occurred and a likelihood that the particular type of event has occurred based on the sensor data.

14. The system of claim 9 , wherein the particular type of event includes one or more of a bleed out, a bleed over, a butt bounce, butt curl, or a water cooling operation.

15. The system of claim 9 , further comprising a melting furnace, a holding furnace and a degasser.

16. The system of claim 9 , further comprising one or more pieces of equipment of a casting system.
