Abstract
The utility model discloses a molten aluminum temperature measuring stick, which belongs to the technical field of thermometers and comprises a sleeve made of metal. A thermocouple is arranged inside the sleeve, a non-metal coating which is high-temperature resistant and does not react with molten aluminum is arranged outside the sleeve. The output voltage of the thermocouple changes along with the temperature, therefore, the output voltage of the thermocouple directly reflects the temperature level of the molten aluminum. When in measuring the temperature of the molten aluminum, the temperature can be measured by the aid of the magnitude of the output voltage of the thermocouple. The sleeve is made of metal material and can not be embrittled in high temperature, the coating is arranged outside the sleeve to prevent replacement reaction between the sleeve and the molten aluminum, and therefore the service life of the sleeve is greatly prolonged.
Description
Technical field
The utility model belongs to the temperature measuring device field, a kind of specifically aluminium liquid tempilstick of measuring temperature of aluminum liquid.
Background technology
Aluminium liquid tempilstick comprises thermopair and sleeve pipe, and thermopair is arranged in the sleeve pipe, and sleeve pipe plays a protective effect to thermopair.The material of sleeve pipe has two kinds: a kind of is metal, is generally cast iron or stainless steel to make; Also having a kind of is pottery.
Adopt metal material to make sleeve pipe, strong Hot swapping reaction can take place with metal in the aluminium liquid under the high temperature, and when measuring temperature of aluminum liquid, sleeve pipe need be immersed in the aluminium liquid for a long time, so that real-time testing, the life-span of sleeve pipe just becomes very short like this, makes that measuring cost rises, and bad during fashion during real-time testing, influence measuring stability.
Adopt stupalith to make sleeve pipe, can avoid the reaction of sleeve pipe and aluminium liquid generation Hot swapping, but pottery at high temperature can become be highly brittle a little less than, at a touch can be cracked with hard thing, sleeve pipe is easy to damage, and causes temperature survey to be interrupted, simultaneous temperature is measured the cost rising.
Summary of the invention
The utility model is at deficiency of the prior art, provide a kind of can not react with aluminium liquid and high temperature under the aluminium liquid tempilstick that also can not become fragile.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: aluminium liquid tempilstick, comprise the sleeve pipe that is made of metal, be provided with thermopair in the sleeve pipe, described sleeve pipe is outside equipped with nonmetallic coating high temperature resistant and that can not react with aluminium liquid.
The output voltage size of thermopair can change along with variation of temperature, and therefore, the output voltage size of thermopair has directly been reacted the height of temperature.When measuring temperature of aluminum liquid, we can utilize the output voltage size of thermopair to measure the temperature of aluminium liquid.Adopt metal material to make sleeve pipe, at high temperature also can not become fragile, sleeve pipe is provided with coating outward, stops the reaction of sleeve pipe and aluminium liquid generation Hot swapping, and improve the serviceable life of sleeve pipe greatly.
The thickness of described coating is more than or equal to 2mm.
Described sleeve pipe is that cast iron is made.
The cost of cast iron is more much lower than stainless steel, because sleeve pipe has been provided with coating outward, cast iron also is difficult for getting rusty again.
The beneficial effects of the utility model are: adopt metal material to make sleeve pipe, sleeve pipe at high temperature can not become fragile yet, be outside equipped with nonmetallic coating high temperature resistant and that can not react with aluminium liquid at sleeve pipe, can stop the reaction of metal and aluminium liquid generation Hot swapping, improve the serviceable life of sleeve pipe, reduced the measurement cost.
Description of drawings
Fig. 1 is a semisectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Referring to Fig. 1, aluminium liquid tempilstick comprises the sleeve pipe 1 that is made of metal, and concrete metal that present embodiment adopts is a cast iron.Be provided with thermopair 2 in the sleeve pipe 1, the sidewall of sleeve pipe 1 and bottom surface are outside equipped with nonmetallic coating 3 high temperature resistant and that can not react with aluminium liquid, the thickness of coating 3 is more than or equal to 2mm, and the end face of sleeve pipe 1 links to each other with connecting pipe 4 one ends, and the other end of connecting pipe 4 is provided with connector lug 5.
During measurement, sleeve pipe 1 stretches in the aluminium liquid, and the heat of aluminium liquid passes to thermopair 2 by coating 3 and sleeve pipe 1, and the output voltage of thermopair 2 changes.The output voltage data of thermopair 2 are passed to measurement instrument or instrument by connecting pipe 4 and connector lug 5, after instrument software calculates, draw the temperature of aluminium liquid.Coating 3 separates sleeve pipe 1 and aluminium liquid in measuring process, stops sleeve pipe 1 and the reaction of aluminium liquid generation Hot swapping.
Claims (3)
1. aluminium liquid tempilstick comprises the sleeve pipe (1) that is made of metal, and is provided with thermopair (2) in the described sleeve pipe (1), it is characterized in that: described sleeve pipe (1) is outside equipped with nonmetallic coating (3) high temperature resistant and that can not react with aluminium liquid.
2. aluminium liquid tempilstick according to claim 1 is characterized in that: (3) thickness of described coating is more than or equal to 2mm.
