Do you know about the steel bar heat treatment production line composed of induction annealing equipment?

Regarding the steel bar production line, we recommend an induction quenching and tempering system for processing prestressed concrete steel bars used in building structures, bridge piers, and concrete pillars. This system can also be used to manufacture other concave threaded steel bars, steel wires, and round steel bars. After quenching and tempering, the concave threaded steel bars reach the mechanical properties of SBPD110/125 and 130/145.

This system is designed to process φ6-φ12mm steel bars and feeds at a moving speed of 35m/min. The system uses one medium frequency annealing equipment for preheating, one high frequency annealing machine for heating before quenching, and another medium frequency annealing machine for tempering. The heating temperature before quenching is 940-950°C, and the tempering temperature is 400°C. The system is also equipped with steel bar feed outage protection, power control corresponding to the feed speed, circulating cooling water pump station and quenching cooling medium circulation system. A single control cabinet links all major operating functions together.

The production process of induction quenching and tempering of PC steel bars is: remove the black skin of the steel bar, cold draw, reforming, preheating (below the Curie point), heating (above the Curie point), quenching, blow drying, tempering, heating and cooling Blow dry one roll of bundle. There is a cutting machine in front of the bale drum, which is started when the bale is full.

Many manufacturers use this production line to heat treat steel bars. The quality of the steel bars produced is good, which meets the needs of production. More importantly, it greatly improves the production efficiency of workers. With the development of technology, this production line has been widely used in the heat treatment industry.
