Drill rods are widely used in industry. In order to meet the needs of work, drill rods need to be heated and heat treated. The more equipment used for heating the drill rod is the super-audio frequency induction heating equipment, and the heating effect is very good.
The super-audio frequency induction heating equipment heats the drill rod, that is, puts the drill rod in the inductor and heats it to 1150°C, and then heat upsetting and forming it into the shape we want. As for how much equipment should be used for heat treatment, it depends on the diameter, heating length and heating speed of the drill rod.
Super-audio induction heating equipment adopts voltage feedback series resonant circuit, adopts IGBT frequency conversion, and the conversion efficiency is as high as 97.5%. Compared with the thyristor, it can save energy by 10%-30%. It can start 99% successfully under any load, regardless of the output power. The size, the power factor is always not less than 0.95, the high-order harmonic component is small, the impact on the power grid is small, it has the function of automatic frequency tracking, and it can always ensure high power factor in the whole process. It has a perfect protection circuit and works reliably. high sex. When it heats and heats the drill rod, it can not only heat the whole, but also heat locally, which can meet the different requirements of customers, which is impossible for traditional equipment.
