Abstract
The utility model relates to a liquid iron constant-silicon sensor which is composed of a sample inlet, a sample cup, a thermocouple, a casing tube, etc., wherein, the sample inlet 8 is positioned at the side face of the sensor, and liquid iron are led to the sample cup through a cavity in a cap mouth 7. The upper part of the sample cup is an upper sample cup 17 which is made of steel and is annular, the middle part of the sample cup is a fireproof sample cup 6, and the lower part of the sample cup is a sample cup pedestal 16 which is a steel cylinder. Therefore, the cooling capacity of the pedestal 16, is highly greater than that of the upper sample cup 17, the temperature difference at both ends of a sample reaches 300DEG. C, the generated thermoelectromotive force has greater value (more than or equal to 5 mv), and the electromotive force changes greatly as the content of silicon changes, which is favorable for increasing measuring accuracy. Simultaneously, the liquid iron flows into the sample cup from the side surface through a cap mouth, which makes the obtained sample more compact.
Description
The utility model relates to a kind of composition sensor, especially measures the sensor of silicone content in the molten iron.
In blast-melted preprocessing process, the silicone content of the pre-desiliconization action need of molten iron fast measuring molten iron, generally be to utilize the molten iron of Seebeck temperature difference heat electromotive force effect exploitation to decide the blast-melted silicone content of the online fast measuring of silicon sensor in the prior art, its ultimate principle is: in a closed-loop path of being made up of two kinds of different metal conductors, when there is different temperature in two contacts in this loop, as long as keep two contacts that temperature difference is arranged, just produce an electromotive force in the loop, the size of its temperature difference heat electromotive force depends on the composition of two internodal temperature difference and these two kinds of metallic conductors, work as the temperature difference, after a kind of metal ingredient was determined, the electromotive force value was the single-valued function of another kind of metal ingredient.For example, the clear 62-107009 of Japanese patent application " desiliconization of hot metal method " discloses silica test sensor in a kind of molten iron, be at the injection port of sensor front end for protruding, in handling process, break easily, during sampling, molten iron enters the sample cup from the end, setting time is long, and getable specimen is fine and close inadequately, the temperature difference between the thermopair of high low temperature both sides less (Δ T=100 ℃), thermopower numerical value is lower, is generally less than 3mv, and is also corresponding less with the variation of silicone content, so little signal requires very high to the accuracy of detection of secondary instrument, simultaneously, the antijamming capability between from the sensor to the measurement instrument is lower, is unfavorable for guaranteeing higher measuring accuracy.
The purpose of this utility model is to obtain a kind of molten iron to decide silicon sensor, and makes the sample that obtains dense, can increase the temperature difference between the thermopair of high low temperature both sides, and makes the thermopower numerical value of measuring bigger.
For achieving the above object, the utility model is achieved in that
A kind of molten iron is decided silicon sensor, form by injection port, sample cup, thermopair and sleeve pipe etc., injection port 8 is positioned at sensors sides, lead to the sample cup through the cavity in the cap mouth 7, sample cup top is last sample cup 17, and the centre is fire-resistant sample cup 6, and the bottom is end Cuo 16, the cooling power of base 16 is greater than last sample cup 17, and thermopair 14 is installed in base 16 and the last sample cup 17.
The end of this sensor is a fire clay base 1.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Accompanying drawing is decided the silicon sensor structural representation for the utility model molten iron.
In the accompanying drawing, injection port 8 is positioned at sensors sides, the end is water-fast mud base 1, and the sensor outermost layer is a flame-retardant layer 15, is outer paper tube 2 in the flame- retardant layer 15,3 is the stay pipe with sample cup location, after the fire-resistant pad 14 of silicate material is heat insulation is the sample cup, and 5 is interior paper tube, and 16 is the sample cup base, top has an aperture can place thermopair 14, the centre is fire-resistant sample cup 6, by fire resistive material such as clay, aluminium oxide, magnesia etc. are made, and the upper end is an annular steel sample cup 17, cavity in water-fast mud cap mouth 7 and the columniform injection port 8 constitutes the passage that molten iron flows into, be that fire- resistant pad 9,10 is a stay pipe on the cap mouth 7,11 is six core connectors, 12,13 is sleeve pipe.
During measurement, after sensor was inserted in the molten iron, molten iron flowed into the sample cup from injection port 8 through fire clay cap mouth, because the molten iron in the cap mouth plays the effect of feeding, makes the densification of materialsing in the sample cup, and it is organized as white pig iron.Simultaneously, the cooling power of bottom low-temperature end is much larger than the top temperature end, this is because low-temperature end is that solid steel column has very strong heat absorption capacity, and a little less than temperature end adopts its heat absorption capacity of annular relatively, can make the temperature difference between the thermopair of high low temperature both sides increase, the thermoelectromotive force that produces is also bigger, and middle sample cup is that fire resistive material is made, and this can eliminate the additional electromotive force that whole steel sample cup brings.
Compared with prior art, the sensor construction that obtains of the utility model can make institute's sample thief Finer and close, sample introduction speed fast (＜2 seconds) behind the insertion molten iron, the sample cooling velocity is also fast, Can finish test in 30～50 seconds, the different knot of heat absorption capacity is adopted at high low temperature two ends simultaneously Structure can reach about 300 ℃ the sample two ends temperature difference, and the thermoelectromotive force numerical value that therefore produces Greatly (〉=5mv), and electromotive force is bigger with the variation of silicone content, is conducive to improve certainty of measurement.
