In July 2025, RHI Magnesita successfully completed the drying and heating of the world’s largest rotary hearth reheating furnace, with an impressive diameter of approximately 58 metres. This achievement marks another milestone for RHI Magnesita in Latin America. The project involved the supply of around 500 tonnes of refractory materials exclusively for the furnace, as well as the execution of a highly technical operation—from numerical simulation to final installation—in close collaboration with our customer Vallourec.

This campaign builds on a legacy of excellence. Back in 2016, a fully mechanised installation system was developed, reducing workers’ exposure and enabling the assembly of preshaped blocks weighing up to 185 kg. That earlier campaign was recognised as a world-record performance for this type of furnace.

For the latest delivery, RHI Magnesita’s role as Vallourec’s strategic partner was once again confirmed, thanks to the combined efforts of our Engineering, Technical Marketing, Operations, and Installation Supervision teams. One of the key innovations was the use of laser scanning—a first for this type of furnace—enabling faster and more accurate future wear assessments.

The result: A project delivered on time, with outstanding quality, technical excellence, and most importantly, zero accidents. Another order for a different unit has already been confirmed, with delivery expected in the coming months.
