Digitized Refractory Lining Monitoring in Steelmaking

Purpose and goal:

The purpose of the project is to enable condition-based maintenance by monitoring linings in steelmaking processes. This would lead to fewer stops, material savings and increased safety. The objectives are to realize a sensor system and a data analysis model for this purpose, and to prepare commercialization.

Expected results and effects:

The effects for end users consist of economical savings thanks to fewer stops for lining changes and reduced consumption of refractory bricks, as well as increased safety and less risk of breakthrough of molten steel. For Agellis Group, which is the commercializing party, the development can lead to the possiblity to be able to offer more complete sensor solutions. The expected reduction of use of refractory bricks also has potential for substaintial positive environmental effects.

Approach and implementation:

The project includes demonstrations in operational environment, in an AOD converter and in an electric arc furnace, in which the system is to be validated and verified. It also includes the development of data analysis models for assessing the condition and life time of the lining, as well as further development of the sensor system and preparation for commercialization.
