Abstract
The utility model discloses a sensor for the surface temperature of an oxygen-free copper cast rod. The sensor for the surface temperature of an oxygen-free copper cast rod is a sensor for rapidly measuring the surface temperature of the oxygen-free copper cast rod, mainly including an open type thermocouple, a porcelain binding post, and a compensating wire. The surface temperature of the oxygen-free copper cast rod which is in motion can be rapidly and accurately measured by the compensating wire being connected with a digital display instrument, then a secondary instrument is matched, which can realize the digital display and the automatic recording of temperature measurement data, and the upper guide process of the cast rod can be adjusted on line.
Description
The utility model oxygen free copper wire rod surface temperature sensor is a kind of sensor that is used for measuring fast the oxygen free copper wire rod surface temperature.
Carry out surface temperature measurement for the object in the motion, its measuring accuracy is influenced by various objective condition, and as the physical dimension of movement velocity, environment temperature, medium kind, measured object, surface appearance etc. all can be drawn bigger error to measurement result.
Contactless temperature-measuring is subject to ambient condition (as dust, thermometric distance etc.) influence as its measuring accuracy such as radiation pyrometer, common-battery pyrometer, leucoscopes.And contact temperature-measuring, as thermocouple pyrometer, pressure thermometer, resistance thermometer etc., the closed type thermopair of comparatively little inertia wherein is then because of being subject to movement velocity, the additional temperature difference influence that sliding friction brings counts more additive error, causes measuring accuracy not high enough.
For the measurement of continuous up-casting oxygen-free copper bar surface temperature, be an important technology, parameter, draw the bar excessive velocities, the cooling of crystallizer secondary is not enough, makes the casting bar surface temperature of drawing too high, and easily oxidized surface reddens in air, the oxygen content of oxygen-free copper bar is risen, and quality descends.Otherwise, as it is slow excessively to draw bar speed, though bar Wen Bugao, but output reduces, cost of products is raise,, just must implement fast, accurately measure the oxygen free copper wire rod surface temperature so how to make the oxygen-free copper bar surface temperature control in the velocity range that realizes good quality and high output.
The purpose of this utility model provides a kind of oxygen free copper wire rod surface temperature sensor that the oxygen free copper wire rod surface temperature is realized fast, accurately measures.
The oxygen free copper wire rod surface temperature sensor is mainly by a branch ostium formula thermopair, the porcelain binding post, and compensating wire is formed.End, open type thermopair contact oxygen free copper wire rod surface is tip-like, and the open type thermopair is fixed on the porcelain binding post post, causes on the digital display instrument with compensating wire.The open type thermopair is made with nickel chromium triangle-Kao copper thermopair electrode material.
Draw on oxygen free copper wire rod in the geneva motion, the opening thermocouple sensor stings thereon with the end with sharp point.According to the relevant law of thermodynamics as can be known, in the thermopair closed circuit that two kinds of different metals are formed, when inserting the third different metal,, then temperature-measuring results is not produced any influence as long as the two ends temperature of the third metal is identical.The utility model is made the surface temperature sensor with the opening thermopair exactly, and oxygen free copper wire rod is inserted the thermopair closed circuit as the third metal.With the hot end connection point of the dut temperature point of oxygen free copper wire rod own, can make measurement result not only accurate like this as surface thermocouple, and owing to this connection can be carried out in moment, so can reach quick temperature measurement again.The thermoelectric force that records of sensor reaches digital display instrument by the compensating wire that is connected on the porcelain binding post thus, thus realized to the oxygen free copper wire rod surface temperature fast, accurately measure.Measurement data is cooperated by twice instrument, realize digital display, automatic record, and can carry out online adjustment to casting rod up-leading technology in view of the above.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the utility model structural representation.
Among the figure: 1, oxygen free copper wire rod, 2, the open type thermopair, 3, the porcelain binding post, 4, digital display instrument, 5, compensating wire.
With reference to accompanying drawing oxygen free copper wire rod surface temperature sensor, primary structure by a branch ostium formula thermopair (2), porcelain binding post (3), compensating wire (5), form open type thermopair contact and be tip-like at moving oxygen free copper wire rod surface contact terminal, thermopair adopts nickel chromium triangle-Kao copper to become, be fixed on the porcelain binding post (3), be connected with digital display instrument with compensating wire (5), tested oxygen free copper wire rod surface temperature can make fast, accurately show during the digital indicator Displaying Meter.
Claims (2)
1, a kind of oxygen free copper wire rod surface temperature sensor is characterized in that being made up of a branch ostium formula thermopair, porcelain binding post, compensating wire.Contact oxygen free copper wire rod surface, open type thermopair end is tip-like, and the open type thermopair is fixed on the porcelain binding post, is connected with digital display instrument with compensating wire.
