The hardening and tempering treatment foresees a heating of the material (bars and/or tubes) up to the austenitizing temperature, followed by an abrupt cooling. A further heating at lower temperatures, normally between 450 ° and 750 ° C and a subsequent cooling follow this.
The temperature of the bars/pipes is constantly controlled by IR pyrometers located at the exit of each section. The entire process can also be easily controlled and managed by an operator via supervisor PC.
The equipment are fully automatic, ensure high production capacity (from 2 to 6 t/h and over), high repeatability of the obtained thermal treatment and a constant quality of the finished product.
