Monitoring of temperature variation in manufacturing process of centrifugally cast pipe using infrared thermography

摘要

In many manufacturing processes, the monitoring of the temperature variation is needed. Manufacturing of a centrifugally cast pipe is processed when the molten metal is poured into the rotating mould with high speed and the thin layer is formed at the inner surface of the mould. Before the rotating mould is heated, the failure rate of the produced pipe is higher than after the process was done several times. In this paper, using the infrared thermography, the temperature variation of the case of centrifugal casting mould during the manufacturing process is monitored, recorded and analysed.
