Matheus Santos - Brazil

Matheus has a Master's degree in Materials Engineering in Technology Development which he obtained from Federal University of Sao Carlos (GEMM/UFSCar) in 2018. His passion for Materials Science regards the steel and refractory role in the social and economic development of our society. This led to an undergraduate exchange programme in POSTECH (Pohang University of Science and Technology) in South Korea, one of the most renowned steel research centres in the world, while more ideas and examples of success were explored. He believes that many improvements in our industry and society require entrepreneurial and innovative ideas and he has been working towards that.

Matheus has visited several steelmaking sites and worked in two steel companies (POSCP and Hundai Steel), which were complemented by his experience in the refractory sector (an internship at Magnesita and a Master's degree sponsored by Saint-Gobain). Beyond his academic and professional activities, Matheus has a creative ability, strong leadership and good communication skills, and he has enrolled in the organisation of group events and activities. Apart from engineering, he enjoys travelling, music and eating good food.

Insights on the optimization of the steel ladle process from a refractory perspective

The modernisation of metallurgical processes such as steelmaking, is intrinsically related to its vessel linings and process control. Refractories are the material commonly applied on the lining because they can withstand the aggressive environment of steelmaking. Monitoring and control have recently showed their importance to general steelmakers, but there is still much information to be explored.

In this context, understanding and predicting the thermal and energy condition of the metallurgical process is a first step in modelling and designing tools to help the identification of the best lining for production solutions. Indeed, optimising steel ladle linings can significantly change the operational conditions, safety, energy consumption, productivity and costs of the process. The study aims to highlight scenarios in which the refractory lining advances the steel ladle operation, according to numerical simulation results for different lining materials and layer thickness.
