Abstract: Billet heating automation is more than the furnace: auto loading, closed-loop temperature control, automatic discharge and infrared pyrometer integration. This article walks through a complete system.

正文： 坯料加热自动化，是把棒料送入感应加热炉，实现自动送料、加热、温度闭环调控、自动出料给下一转运机械手。

工作流程
Process flow

棒料自动上料→连续推入感应线圈内部加热→红外测温实时采集坯料出口温度→系统根据实测温度自动调节加热功率，温度过高降低功率，温度偏低提高功率；合格温度坯料自动推出炉口，等待机械手抓取转运。
Bars load automatically and push through the induction coil. An IR pyrometer reads the exit temperature; the system raises or lowers power to hold setpoint. Billets within tolerance are discharged and wait for the transfer robot.

自动化重点
Automation essentials

• 温度闭环：红外测温信号回传给加热电源，形成闭环，而不是固定功率加热，补偿棒料尺寸、进给速度波动。
  Closed loop: the pyrometer signal feeds back to the power supply – not fixed-power heating – compensating for bar size and feed variations.
• 故障报警：棒料卡料、加热异常超温自动报警停机。
  Alarms: jammed bars or overheating trigger automatic alarms and shutdown.
• 时序对接：出料和后端转运机械手信号互锁，炉口不能随意出料。
  Interlock: discharge is interlocked with the transfer robot – nothing leaves the furnace mouth freely.
• 记录功能：记录每一支坯料加热温度，存入数据库，用于批次追溯。
  Records: every billet’s heating temperature is logged to a database for batch traceability.

注意事项
Caution

红外测温镜头需要吹扫保护，避免水汽、氧化皮粉尘遮挡镜头，造成测温失真。
The pyrometer lens needs an air purge – moisture and scale dust will blind it and distort readings.
