AIST Foundation Steel Intern Scholarship
Miguel A. Ojeda Medina
This summer, I had the opportunity to complete an internship at Ternium México at the Planta Universidad in Monterrey, N.L.. Over the course of two months, I worked in the Rolling – Technology & Processes department, where I carried out projects focused on pickling, cold rolling and operational safety.
One of my main projects was documenting the neutralization system, with the goal of explaining how it works and detailing the tasks operators must perform to meet the system’s objectives. This document aims to enhance operator safety and minimize environmental impact by preventing contamination from improper use.
My second project centered on the Morgoil lubrication system, to which I integrated two additional subsystems: mist oil units and hydraulic units, all part of the cold rolling lines. I documented how each system operates, identified key variables (such as pressure, temperature, flowrate and level), outlined necessary procedures and provided recommendations to ensure optimal equipment performance. This information is intended to train operators to troubleshoot common issues safely and efficiently.
Additionally, I developed a third project related to crane hook latch safety, proposing four ideas — two of which were accepted and are now under evaluation by the engineering and safety departments for implementation.
On a daily basis, I prepared production reports for the rolling and pickling lines at the plants in Mexico and Argentina, identifying and explaining any deviations. I also attended meetings on safety, quality and management, which gave me insight into how these topics are addressed in a steel company. I conducted plant surveys and visited other Ternium facilities, broadening my understanding of industrial processes.
To carry out these projects, I used digital tools such as tablets and laptops to systematically record technical and visual information via a document management system (OneDrive). I also employed CAD software to create three-dimensional models of the systems, which facilitated accurate representation of key components and their interactions within the process.
I applied a DMAIC-based approach (Define, Measure, Analyze, Improve, Control), commonly used in continuous improvement projects. This methodology allowed me to structure my work from identifying operational issues to proposing practical solutions. I interviewed experienced operators to capture best practices, which I validated against internal technical documentation — manuals, data sheets, presentations and historical records. I also used activity timelines to ensure that objectives were met on schedule.
I collaborated with multiple departments — processes, operations, electrical and mechanical maintenance, safety, pickling and rolling operators, and emulsion specialists — and gained in-depth knowledge of the systems, their variables and the importance of following established procedures to avoid risks and environmental damage.
Throughout this experience, I developed technical skills such as mastery of industrial terminology and familiarity with specialized equipment. In terms of soft skills, I strengthened my leadership, initiative, active listening, teamwork, respect and responsibility.
The most challenging aspect was gathering and understanding all the technical information needed to produce clear, concise and useful documents. The most rewarding part was witnessing the scale of the steel industry firsthand — from the size of the machinery to the complexity of the processes. This experience transformed my professional perspective and has motivated me to pursue a career in the steel sector.
I would like to extend my special thanks to Ing. José Eduardo Solís M. for trusting me as his intern, for entrusting me with such meaningful projects, and for his guidance and advice; and to Ing. Giuseppe F. Pessolano P. for his constant support, both technical and personal, which was crucial to my development.
Finally, I am grateful to AIST for providing this opportunity, which marked a turning point in my professional life and helped me discover my passion for the steel industry.
