Mexican steelmaker ArcelorMittal Mexico announced the successful replacement of a transformer on Electric Arc Furnace No. 2 at its steel plant, resulting in an 18 percent increase in foundry capacity. The company said the project was completed in just 14 days and described it as one of the most efficient recent operational projects at the plant.
End-of-life replacement
According to ArcelorMittal Mexico, the previous transformer had been in service since 1988 and had reached the end of its life. For more than three decades, the equipment maintained the productivity of the steel mill's electric furnaces. The company stressed that transformer replacement poses a major technical challenge, both due to the size of the equipment and the precision required during installation.
New TAMINI transformer increases power to 175 MVA
ArcelorMittal Mexico said the newly installed transformer was supplied by Italian manufacturer TAMINI. With the modernization, the power of the electric arc furnace increased from 126 MVA to 175 MVA. According to the company, this increase allows for an 18 percent increase in the number of heating times per day, strengthening the overall production process at the electric steel mill.
