In 2007, Alfran supplied all the heat treatment materials for expanding the production capacity of the Votorantim cement kiln in Niebla and Córdoba. Alfran carried out all the basic and detailed engineering work for both projects. The work involved designing the heat-resistant coating of each piece of equipment, under the supervision of our operations department, who ensured that the materials were installed correctly. Our subsidiary Intec-Heat was responsible for overseeing the setting and drying process of the heat-resistant concrete. They monitored the controlled removal of water to avoid explosions in the equipment. Intec-heat designed the engineering for developing the drying curves and the study for each application.
