Heat treatment
HEAT TREATMENT OF STEEL
At Ebroacero, We perform the necessary heat treatments for the different types of steels we manufacture, adapting each process to the requirements of the final industrial application. We precisely control heat cycles to optimize critical properties such as mechanical strength, toughness, dimensional stability and wear behavior.
We have the technical capacity to adjust each treatment to the specific requirements of your project, guaranteeing the metallurgical integrity of each part.
HEAT TREATMENT FURNACES
PaFor heat treatment, Ebroacero has four industrial furnaces that cover different production needs:
- Rectangular mobile hearth furnace in which a maximum temperature of 1200ºC can be reached with a maximum load of 20 tons, dimensions 4000 x 3500 x 1970 mm.
- Rectangular mobile hearth furnace in which a maximum temperature of 1000ºC can be reached with a maximum load of 30 tons, with dimensions 6500 x 3500 x 1700 mm.
- Rectangular furnace in which a maximum temperature of 1200ºC can be reached with a maximum load of 3.5 tons, with dimensions 5000 x 1500 x 1700 mm.
- Circular pit furnace in which a maximum temperature of 1000ºC can be reached with a maximum load of 30 tons with dimensions of 6000mm diameter x 2500 mm height.
TYPES OF HEAT TREATMENTS AT EBROACERO
We perform different heat treatments of steel according to the mechanical needs of each part:
- Annealing
- Normalised
- Water quenching or air quenching
- Tempering
- Stabilized or Stress Relieving
Each process is selected according to the type of steel and the final service conditions.
In quenching and tempering heat treatments, for example, we seek to improve hardness and mechanical strength without compromising toughness, while maintaining its impact absorption capacity. In other cases, such as normalizing, the objective is to homogenize the crystalline structure of the material after the casting phase, essential to eliminate casting heterogeneities and prepare the steel for subsequent processes, or in annealing, to eliminate internal stresses generated during solidification or machining, which improves the dimensional stability of the part and facilitates its ductility for critical operations.
