Iron & Steel Furnaces
The iron and steel industry requires the most durable, reliable, and long-lasting solutions in industrial furnace applications due to extreme heat, slag-induced chemical wear, pressure variations, and the demanding operational conditions of metallurgical processes. By carrying over more than 25 years of furnace engineering expertise into the specific needs of this sector, GTR offers end-to-end solutions across a wide range of applications, from rolling mills to blast furnaces, from coke oven batteries to heating furnaces.
Industry Requirements
• Refractory applications resistant to high temperature, slag, and chemical erosion
• Hot repair applications in coke oven batteries aimed at minimum downtime
• Refractory design and installation fully integrated with the furnace shell and steel supporting structures
• Scaffold engineering and site safety in compliance with international standards
• Controlled drying, thermal regime management, and reliable furnace heat-up processes
The variable temperature cycles and abrasive processes of annealing furnaces used in rolling mills require long-life lining design and energy efficiency. In these facilities, primary refractory installation, hot repair applications, and the integration of steel construction elements—each extending refractory service life—are of critical importance.
In blast furnaces, temperatures reaching up to 2100°C in the hearth, belly, and shaft zones, combined with chemical attack and high pressure, necessitate advanced refractory applications and engineering solutions supported by technological steel structures. In addition, the precise checker brickwork of hot-blast stoves is a key determinant of thermal efficiency and fuel economy.
