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.

Sensing events in a metal casting system

Systems and associated methods are provided for controlling the shape of an ingot head during formation. At the end of a cast, prior to forming the ingot head, chill bars or other cooling structure may be lowered into an ingot mold and define a reduced casting footprint for forming the ingot head. Supplemental molten metal may be fed into the reduced casting footprint, and the chill bars may be moved laterally towards the center of the ingot, further reducing the casting footprint. As additional molten metal fills the reduced mold footprint, the ingot may be lowered relative to the chill bars to further increase the height of the ingot head. Additional molten metal may be added until the desired shape of the ingot head is formed.

Method of controlling the shape of an ingot head

A monitoring system may monitor a casting environment, for example, including a mold. The monitoring system may include a camera and a computer system. The camera may be positioned to capture or detect optical data associated with one or more components in a casting environment. The camera may send the optical data to the computer system and the computer system may generate a profile associated with the casting environment. The profile may be compared with a baseline profile to determine whether a particular event has occurred. Based on the event that may have occurred, operating instructions can be generated. The operating instructions may be used to adjust the casting process.
