Description
Technical field
The utility model relates to a kind of temperature measuring equipment, specifically, relates to a kind of continuous temperature measuring device for molten.
Background technology
The temperature of Metal in Tundish all has a direct impact stabilizing continuous casting operation, raising slab quality, minimizing bleedout accident etc.Existing Metal in Tundish thermometric adopts the mode of artificial thermometric mostly, survey crew needs repeatedly duplicate measurements in high temperature environments, but the temperature value of interruption can only be obtained, can not measure and understand the consecutive variations trend of liquid steel temperature continuously, and the degree of depth inserting molten steel due to thermometric bar when to measure for each time differs, therefore can there is a certain distance with actual temperature in measured temperature.Some enterprises are also at some tundish continuous temperature measurement systems of application at present, but it is short to there is serviceable life, the inaccurate problem of thermometric.
For the problem of above-mentioned technology, at present effective solution is not yet proposed.
Utility model content
Short for serviceable life for continuous temperature measuring device for molten in prior art, and the inaccurate problem of thermometric caused due to misoperation, the utility model proposes a kind of continuous temperature measuring device for molten, this continuous temperature measuring device for molten can solve above-mentioned technical matters.
The technical solution of the utility model is achieved in that
The utility model provides a kind of continuous temperature measuring device for molten, comprise Wolfram rhenium heat electric couple, alundum tube is set with outside described Wolfram rhenium heat electric couple, cavity between described Wolfram rhenium heat electric couple and alundum tube is sentenced alumina powder and is filled, and described alundum tube and aluminium carbon protection tube are combined as a whole by the mode of hydrostatic profile; The output line of Wolfram rhenium heat electric couple afterbody leads to described continuous temperature measuring device for molten outside, and is connected with signal processing system.
Further, described signal processing system connects temperature display system.
The beneficial effects of the utility model:
1) the utility model can reduce molten steel to the erosion of tube wall and oxidation to a great extent by adopting aluminium carbon protection tube, increases the service life;
2) the utility model is by adopting Wolfram rhenium heat electric couple, the utility model is had, and high temperature resistant, thermoelectrical potential is large, thermoelectrical potential is good with the linear relationship of temperature, Heat stability is good, low price and observable temperature scope extensively feature such as (0 ~ 2000 DEG C), and thermometric is more accurate;
3) the utility model is by adopting the mode that is connected with signal processing system of thermopair, can measure and understand the consecutive variations trend of liquid steel temperature continuously;
4) structure that alumina powder is filled at the cavity place between Wolfram rhenium heat electric couple and alundum tube can absorb the next impact of mechanical shuttle belt, makes it have the performance of stronger heat shock resistance and mechanical vibration impact, extends the serviceable life of temperature measuring equipment.
