Features of pc steel bar induction heating quenching and tempering line

The induction heating quenching and tempering line for pc steel bars has three heat treatment heating methods: gas heating, resistance furnace heating and induction heating. One of the key points of gas heating and resistance furnace heating for the heat treatment of pc steel bars is that the overall uniform and efficient heating and quenching are difficult to achieve. This is one of the reasons that the deformation of the workpiece and the uneven hardness after quenching and tempering are difficult to control , And induction heating heat treatment is more economical and reasonable, pc steel bar induction heating quenching and tempering line through the induction heating heat treatment quenching and tempering line, the product is quenched and tempered to improve the performance of the steel. The main features of induction heating heat treatment quenching and tempering are fast heating speed, less surface oxidation, quenching and tempering process in the process of rotary heating, good straightness and no bending of steel after quenching and tempering. Long product products such as pc steel rod quenching and tempering line are widely used in heat treatment. In foreign countries, induction heating is also used more in heating methods.
