Equal-section steel pipes are heat treated using medium frequency induction heating power supply

Steel pipes of equal cross-section adopt medium frequency induction heating for induction heating, quenching and tempering. For relatively long steel pipes, in order to facilitate operation and are not suitable for high-rise factories, horizontal induction heating is used, with the inductor fixed and the steel pipe According to a predetermined speed to prevent the rotation side from being transferred longitudinally, it is heated by an inductor. If quenching is required, add a water sprayer at the rear end of the sensor. When the steel pipe wall is thick, medium frequency induction heating is used. During quenching, water spray cooling is required from both the inner and outer sides of the steel pipe at the same time to meet the technical performance requirements of the steel pipe. When using this induction heating method to perform single-piece periodic operations on steel pipes, uneven heating temperature distribution occurs at the end of the steel pipe, so a false load is added to the end of the steel pipe.

For example, the temperature distribution of induction heating of a steel pipe with a diameter of 610 and a wall thickness of 20mm. A V-shaped heating phenomenon appears at the end of the steel pipe. The depth of this V-shape increases as the wall thickness t of the steel pipe increases, and the width of the V-shape increases with the increase. It increases with the increase of the length L of the first coil of the sensor. In view of the uneven heating temperature at the end of the sensor, the method of preheating the end of the steel pipe was used. That is, the end of the steel pipe was first put into the sensor and heated for a certain period of time before the steel pipe was moved. The temperature difference has gone better. According to relevant information, foreign countries have used the method of preheating sensors to preheat the V-shaped part of the steel pipe, and added a preheating sensor to the equipment that records crude oil.

For the quenching of large-diameter steel pipes, according to your company's different heating requirements and production efficiency, our company will make different equipment plans for you, and make the most reasonable layout according to your plant planning to optimize the use of equipment.
