Intelligent Blast Furnace Operation Support System

Gain visibility into the internal condition of the blast furnace, a highly complex process with long operational time constants, through a Digital Twin based virtual blast furnace model.
Provides operational guidance and early anomaly detection alerts, helping operators maintain stable, efficient, and reliable blast furnace performance.

Solution Point

A lineup of advanced models enables stable blast furnace operation through heat guidance which predict furnace heat for optimum action, and early detection of abnormalities in permeability, furnace heat, and slag level.
Also includes indexes/mechanisms for automatic evaluation of the reliability of operational and sensor data, which is extremely important in realizing the digital twin.
