Steel strand is a product twisted by multiple steel wires, and there are many types, such as galvanized steel strand commonly used for overhead conductors, prestressed steel strand for bridges, galvanized steel strand for optical cable reinforcement Stranded wire etc. In order to meet the needs of the work, steel strands usually require annealing heat treatment.
Annealing is mainly used to reduce the hardness of the workpiece and improve its toughness and plasticity, and the same is true for the annealing of steel strands. In the past, people used traditional equipment for annealing heat treatment of steel strands. Due to the limitations of the equipment, the oxidation and decarburization of the produced steel strands were particularly serious, which greatly affected the normal use of the steel strands.
Now, with the continuous improvement of the production technology level, the high-frequency induction annealing machine known for its high technology has appeared. Once this equipment came out, it has been loved by many heat treatment manufacturers. According to them, using this equipment for annealing heat treatment of steel strands not only has a much better effect, but also improves the production efficiency a lot.
The high-frequency induction annealing machine adopts IGBT inverter power devices, which are highly efficient and energy-saving, and the heating is easy to control. The heating current value and heating voltage value can be set, and the current, voltage, power and frequency are all displayed. The operation is very intuitive and simple. When it anneals the steel strand, the heating speed is very fast, and the annealing process can be completed in a few seconds, which effectively avoids the occurrence of oxidation and decarburization, ensures the annealing effect of the steel strand, and makes the annealed The appearance of the steel strand is smooth and bright, which meets the requirements of its work.
