Description
Technical Field
The invention belongs to the technical field of hot isostatic pressing equipment, and particularly relates to an over-temperature monitoring method and device of a hot isostatic pressing machine.
Background
Hot Isostatic Pressing (Hot Isostatic Pressing, HIP) is an apparatus for applying an isotropic static pressure to a powder or a sintered blank (or a part) to be compacted in a high-temperature and high-pressure sealed container by using a Hot Isostatic Pressing technology and using high-pressure argon as a medium, so as to form a high-density blank (or part).
The working temperature of the hot isostatic pressing machine needs to be controlled within a certain process requirement range, and when the temperature exceeds an overhigh temperature, the product is scrapped. Therefore, it is desirable to monitor the temperature of various zones within the hipping machine containment in real time. The temperature monitoring system of the existing hot isostatic pressing machine obtains the temperature in the hot isostatic pressing machine container through a thermocouple, and the temperature in the hot isostatic pressing machine container is monitored and patrolled through manually recording numerical values on a parameter interface.
However, the method has relatively high dependence on operators, and the equipment may be over-heated due to negligence of the operators, which brings about serious safety accidents, so that potential safety hazards still exist.
CN110901148A discloses a hot isostatic press machine control backup pair automatic switching control system and a control method, comprising a pressure container and a controller connected with the pressure container; the controller comprises a temperature measurement signal input module, a central processing unit and a temperature control signal output module which are connected with the pressure container, and the temperature measurement signal input module and the temperature control signal output module are respectively connected with the central processing unit. Specifically, the method comprises the steps of obtaining a hot isostatic pressing machine thermocouple signal; distinguishing a temperature control thermocouple and a standby thermocouple from the obtained hot isostatic pressing machine thermocouple signals; judging whether a fault occurs; adjusting the heating element heating value in the pressure container, and controlling the temperature of the hot zone; the system can find the abnormal phenomenon of the thermocouple in the temperature control process as early as possible, can switch the standby thermocouple into the temperature control thermocouple in real time when the temperature control thermocouple breaks down, ensures the continuity and stability of the temperature control of the hot isostatic pressing machine, and avoids potential safety hazards and economic loss caused by the failure of a certain thermocouple. But the temperature monitoring process still depends on operators, and the temperature monitoring device cannot automatically and timely react to the over-temperature phenomenon, so that the product is prevented from being scrapped.
