Data Science

Technology for Improvement of End-Point Hitting Accuracy by Estimation of Carbon Concentration and Hot Metal Temperature in Converter Operation

Improves productivity and reduces costs by improving the hit rates of the hot metal carbon concentration and temperature!

Solution Point

Improvement of model accuracy by utilizing DX technology.
Substantially improves estimation accuracy at the end-point of converter operation by mutual sequential correction (data assimilation) between the physical model and measured data.

Features 01

Expected Problems

・Is reblowing frequently required due to failure to hit the end-point carbon concentration or temperature in converter operation?

・Are you worried about decreased converter productivity and increased costs?

・Is the negative impact of over-oxidation in the converter on product quality a problem?

Features 02

Technology highlight

・Estimation error is reduced by creating a CPS* model for real-time estimation of the end-point carbon concentration and temperature in converter operation.
＊CPS：Cyber-Physical System

Features 03

Proposed Solutions (Examples)

Can be supplied by retrofitting the existing converter system.
