Degassing machine temperature monitoring device

Abstract

The invention discloses a degassing machine temperature monitoring device which comprises a GBF degassing machine. The GBF degassing machine is provided with a titanium alloy thermocouple protection tube. A thermocouple is arranged in the titanium alloy thermocouple protection tube. The thermocouple is connected with a control panel of the degassing machine through a compensating lead wire. In the degassing process, a thermodetector does not need to be manually used to detect a temperature in a flowing mode, so that the personal safety of stuffs is ensured, the waiting time and the aluminum water heat loss are reduced, and the working efficiency is improved. The thermocouple protection tube is made of a titanium alloy material, so that the degassing machine temperature monitoring device is corrosion-resistant and has good effects of resisting chilling and heat shock and long service life.

Description

technical field [0001] The invention relates to a temperature monitoring device for a degasser, and relates to the real-time monitoring of the temperature of molten aluminum when the degasser is degassing in aluminum alloy casting. Background technique [0002] In the production of aluminum alloy products, casting molding is a very popular production method. In casting production, in order to achieve the best casting effect and reduce product defects, the temperature control of molten aluminum is very strict, generally within the required temperature ±10°C, if it exceeds the range, it cannot be added to the casting machine for production. [0003] In the existing production process, after the degassing of the rotary refining degasser (GBF), the temperature of the molten aluminum is generally detected with a hand-held thermometer to see if it is qualified, but the process has many shortcomings: in large-scale production In the process, there are many water packs, and each pa...

[0003] In the existing production process, after the degassing of the rotary refining degasser (GBF), the temperature of the molten aluminum is generally detected with a hand-held thermometer to see if it is qualified, but the process has many shortcomings: in large-scale production In the process, there are many water packs, and each pack of aluminum water needs temperature detection, which increases the labor intensity of employees and reduces production efficiency; the general thermocouple material is not resistant to aluminum water erosion in moving aluminum water, and is extremely easy to corrode. On the one hand, the impurity components in the aluminum water will increase, reducing the quality of the aluminum water; The thermocouple protective sleeve is very easy to hang slag and crack, and the service life is shortened; the temperature measurement and temperature recording of the handheld thermometer must be close to the degasser, which will affect the personal safety of the operator
