1) Specifikacije radnog komada i konfiguracija senzora

A total of 3 sets of quenching inductors are required . The heating range of the workpiece is 16-32mm . The quenching part uses super audio frequency power, the power is 250KW , and the frequency is designed at 10-30KHz to ensure uniform heating.

Serijski broj	specifikacija	Raspon ( mm)	dužina (m)	Senzor za prilagođavanje
1	Φ 16- Φ 19	16-19	8-11	GTR-19
2	Φ 22- Φ 25	22-25	8-11	GTR-25
3	Φ 28.6- Φ 32	28.6-32	8-11	GTR-32

2) Opis toka procesa

First, manually place the required workpiece (sucker rod) on the feeding storage rack (usually hoisted to the top by a crane), the storage rack is equipped with an integral turning mechanism, and the turning mechanism will be adjusted according to the set beat (time). The material is turned to the feeding conveyor, and then the feeding drives the bar material forward, and the material is sent to the quenching heating inductor. Then the workpiece is heated by the quenching heating part. After rapid heating, the workpiece (workpiece rotation) is driven by the inclined roller to pass through the quenching water spray ring for spray quenching. The entire quenching area is covered by a transparent protective cover.
