Abstract
A method for identifying, classifying, and sending notification of an electric arc furnace's (EAF) anomalies to improve the EAF efficiency. The method includes the steps of establishing baseline state measurements of the EAF, receiving new state measurements of the EAF and statistically testing the new state measurements against the baseline state measurements. The method further includes the steps of identifying as an anomaly a failed statistical test, classifying the identified anomaly and sending notification of the classified anomaly to a configurable list of recipients.

A method for identifying, classifying, and sending notification of an electric arc furnace's (EAF) anomalies to improve the EAF efficiency and reliability, the method comprising the steps of:
- establishing baseline state measurements of the EAF;
- receiving new state measurements of the EAF;
- statistically testing the new state measurements against the baseline state measurements;
- identifying as an anomaly a failed statistical test;
- classifying the identified anomaly;
- sending notification of the classified anomaly to a configurable list of recipients.
A system for continuous monitoring of an Electric Arc Furnace (EAF) to identify and classify EAF anomalies to improve the EAF efficiency, the system comprising:
- a device configured to:
- receive and establish baseline state measurements of the EAF;
- receive new state measurements of the EAF;
- perform statistical testing of the baseline state measurements against the new state measurements;
- identify as an anomaly a failed statistical test;
- classify the identified anomaly;
- and
- notify a configurable list of recipients of the classification.
An electric arc furnace (EAF), the EAF comprising:
- a refractory-lined vessel covered with a retractable roof, through which one or more graphite electrodes enter the EAF;
- a power system, powering the EAF;
- at least a first electrical metering device communicably coupled to the power system;
- an EAF process and control system measuring and controlling the EAF;
- at least a first programmable logic controllers (PLC) communicably coupled to the EAF process and control system;
- a computing device;
- the computing device communicably coupled to the first electrical metering device and the PLC;
- wherein the computing device is configured to:
- receive and establish baseline state measurements of the EAF;
- receive new state measurements of the EAF;
- perform statistical testing of the baseline state measurements against the new state measurements;
- identify as an anomaly a failed statistical test;
- classify the identified anomaly;
- and
- send notification of the classified anomaly to a configurable list of recipients.
