Description

Technical Field

[0001] The present invention relates to the field of casting technology, in particular to a device for connecting, fixing and quickly replacing thermocouples of a vacuum melting furnace heater and an insulation furnace, which has the characteristics of simplicity, stability, reliability and consistency. Background Art

[0002] In the field of precision casting, high-temperature alloy blade casting requires specific processes. The temperature of the mold shell of the casting blade must be precisely and accurately monitored to determine whether it meets the process requirements, which has a critical impact on the quality of the high-temperature alloy blade. The temperature of the high-temperature alloy liquid is generally monitored using thermocouples. These devices place extremely high demands on the stability of the thermocouples and the consistency of the measurement points at the thermocouple's temperature measuring end. This consistency is essential to ensure accurate mold shell temperature control. Furthermore, the replacement and disassembly of the thermocouples and thermocouple protection tubes are highly demanding.

[0003] Currently, the spatial position of the thermocouples and thermocouple tubes in the heater holding furnace, including horizontal height, horizontal lateral depth, and horizontal longitudinal depth, is poorly controlled. Furthermore, the consistency of the positions of the thermocouples and thermocouple tubes before and after replacement is difficult to guarantee, making them inconsistent and unstable, which directly impacts the control of the mold shell temperature. Furthermore, replacing thermocouples and thermocouple tubes is cumbersome and easily damages the thermocouples, creating risks of thermocouple breakage and loose connections. This impacts the accuracy of the mold shell temperature control and directly affects the quality of the high-temperature alloy blades and the stability of the product.

[0004] Currently, the control of thermocouples and thermocouple temperature measuring tubes is simple, and the replacement process is complex. The thermocouple is simply placed in the thermocouple temperature measuring tube without a fixed device. This leads to uncontrollable factors such as inconsistent depth and different contact points within the thermocouple temperature measuring tube. Furthermore, the thermocouple itself cannot be adjusted to different spatial positions according to different mold shells. As a result, the applicability of the temperature measuring point is relatively narrow, which is not conducive to precise control of the mold shell temperature. Furthermore, the consistency and stability of the thermocouple and thermocouple temperature measuring tube cannot be guaranteed before and after replacement, resulting in low operational efficiency. Furthermore, the replacement process is prone to damage to the thermocouple, reducing its utilization rate and accuracy. Summary of the Invention

[0005] The present invention provides a device for fixing thermocouples in vacuum induction furnaces, heaters, and holding furnaces. The device precisely adjusts the spatial position of thermocouples, ensuring accurate, efficient, stable, and consistent temperature measurement. Furthermore, the device allows for rapid replacement of thermocouples and thermocouple tubes, improving thermocouple stability. This reduces the risk of thermocouple damage, significantly improves operating efficiency, and ensures consistent and controllable temperature measurement points.
