Principle of sensor for quenching and tempering equipment of sucker rod

Don't you take a look at the manufacturing principle of the sensor from the manufacturer of quenching and tempering equipment for sucker rods?

Sensor manufacturing process:

The ratio of the inner diameter of the induction coil to the outer diameter of the billet in the quenching and tempering equipment for sucker rods is within a reasonable range and is designed based on the process parameters provided by the user. The inductor coil is mainly made by winding rectangular copper tubes, acid washing, water pressure testing and other main processes, and then fixed as a whole. After the entire inductor is made, it forms a rectangular prism with good vibration resistance and integrity.

The two ends of the sensor are protected by copper plates, which can effectively prevent electromagnetic radiation from causing harm to the operator. The inner diameter size of the sensor for the quenching and tempering equipment of the sucker rod: The inner diameter of the copper coil of the sensor needs to be lined with furnace lining to protect the copper coil of the sensor. The inner diameter of the coil determines the heating efficiency. And the furnace lining needs to have sufficient strength, without cracking or deformation during heating use. There should be sufficient clearance between the inner diameter of the furnace lining and the diameter of the billet to ensure that the billet can pass smoothly without touching the furnace lining. At the same time, the phenomenon of billet deformation and contact with the furnace lining due to billet protrusion caused by uneven billet end face during pushing should also be considered, which may wear the furnace lining. Therefore, when the inner diameter of the coil is constant, while ensuring the strength of the furnace lining, the larger the inner diameter of the furnace lining, the more advantageous it is for the workpiece. The furnace lining of the quenching and tempering equipment sensor for the sucker rod adopts a practical segmented integral casting and knotting process, and the central knotting method is commonly used when knotting the furnace lining. This knotting process places the billet in the middle of the sensor, which is beneficial for the uniform heating temperature of the billet and more in line with the principle of proximity effect in electromagnetic induction.

Segmented manufacturing process for quenching and tempering equipment sensors for sucker rods: Segmented structure sensors not only facilitate manufacturing and maintenance, but also give different functions to each section according to temperature gradient requirements. Variable power density design combined with two-point temperature control can make heating temperature more accurate.
