Application and Heat Treatment Parameters of Hot Rolled Twist Drill

Hot-rolled twist drill adopts advanced technology. The new IGBT hot-rolled twist drill heat treatment equipment G is mainly composed of IGBT. The power circuit is characterized by series oscillation. The control circuit is frequency automatic. The new IGBT hot-rolled twist drill heat treatment equipment G multi-closed-loop control (refers to return the controlled output to the input in a certain way and control the input end). A control relationship of influence. The output is fed back to the input and participates in the re-control of the output. This is the purpose of closed-loop control, which is achieved by feedback. Positive feedback and negative feedback are two basic forms of closed-loop control. ) It is the main characteristic.
