Description
Technical field
The utility model relates to W-Re fast thermocouple production facilities technical field, especially tungsten-rhenium wire hinge joint machine.
Background technology
Fast thermocouple, also known as quick temperature measurement sensor, is widely used in the temperature survey of the molten steel of the technological processes such as converter, electric furnace continuous casting, double refining, molten iron and other molten metal.Thermocouple is that A, B are just called thermode (or thermocouple wire) by one end of two different conductors or quartz conductor wire materials A and B is welded formation.The one end welded is placed in dut temperature t place, is called the hot junction (or claiming measuring junction, working end) of thermocouple; Non-solder end is called cold junction (or reference edge, free end), and cold junction is then placed in the thermometric environment of t0.Then a C/LOOP is formed as two of thermocouple cold junctions are also coupled together, then when hot-side temperature and cold junction temperature unequal, electric current is had to flow through in loop, this explanation creates electro-motive force in the loop, temperature due to thermocouple two contact places is different and electro-motive force that is that produce is called thermoelectricity (moving) gesture, above-mentioned reason resembles and is called pyroelectric effect, and thermocouple utilizes pyroelectric effect to carry out measuring tempeature.
What the conductor material of thermocouple was conventional has platinum rhodium, NI-G-nisiloy, the use of this bi-material can trace back to the forties in last century, this material of discovered in recent years tungsten-rhenium alloy also meets thermometric conductor condition, so this material has also been applied in fast thermocouple making gradually, himself also really have the incomparable advantage of other material, Wolfram rhenium heat electric couple, compared with conventional platimum-rhodium thermocouple, has some advantage following simultaneously:
1, domestic W-Re aboundresources, cheap;
2, wide between tungsten-rhenium wire temperature measuring area, short-period used is up to 3000 DEG C, and platinum-rhodium wire is 1800 DEG C;
3, electrical resistivity is little, and thermo emf is large, and sensitivity of thermometry is good;
4, mechanical strength is high, not fragile after machining.
In the making of current W-Re fast thermocouple, what thermoelectricity polar filament was used is W-Re 3(positive pole)-W-Re 25(negative pole).The thermo wires processing technology of W-Re fast thermocouple has three process: the first step, the several knot of both positive and negative polarity W-Re skein silk; Second step, cuts off several knot by certain length segmentation; 3rd step, welds the silk material cut off near the place tangled.The tungsten-rhenium wire responded to for positive negative potential is the core component of W-Re fast thermocouple, the quality of these parts, directly have influence on steel mill to liquid steel temperature sampling reflect objective temperature.All the time, it is all process manually that tungsten-rhenium wire makes, both positive and negative polarity welding adopts the mode of directly welding mostly, the number that tangles making hank knotting by hand does not have fixed value, and the knot of the process wire strand system manually made is inconsistent, and it is tight that some pines have, due to the characteristic that tungsten-rhenium wire is more crisp, the solder joint that tangles easily ftractures, and directly causes product rejection, has a strong impact on the yield rate of W-Re fast thermocouple.
