Induction Q&T Line for Bars: Synchronized Feeding & Smart Water Control

English: Heat-treat producers seeking repeatable bar Quench & Temper with high automation, robust diagnostics, and clean in-line control.

Fast heating; VFD-driven roller feeding with module-to-module speed sync; anti-slip detection with safe stop; grouped temperature/water monitoring (LED + PLC/HMI).

1) Feeding mechanics

• Infeed roller conveyor (VFD): HMI shows mm/min; auto conversion from frequency to linear speed by bar diameter.

• Support-roller feeder (VFD): synchronized with the infeed conveyor.

• Active pressure roller (pneumatic): no bar→up; bar present→down (sensor-driven).

• Slip control: below setpoint→alarm; bar stop→automatic shutdown.

• Intermediate feeder: synchronized with infeed module.

• End feeder: slightly faster; pneumatic drop HMI-timed to space bars 2–5 mm.

Outcome：Stable kinematics, consistent spacing, smooth hand-off into heating/quench zones.

2) Water & temperature control

• Normally-closed thermal switches; LED indicators pinpoint faults.

• Each node is a separate control group (smallest diagnostic unit) into PLC; statuses on HMI.

Groups:

1) Each inductor; 2) Capacitor bank; 3) Reactor; 4) Thyristor/others; 5) Water-cooling loop (pressure/flow).

Outcome：Targeted diagnostics, reduced downtime, predictable maintenance.
