Abstract
Description
Vynález se týká sondy pro přesné měření teploty tuhnutí taveniny.The invention relates to a probe for accurately measuring the freezing point of a melt.
V současné době se pro laboratorní i provozní mmření teploty tuhnutí taveniny užívá různých skořepinových keimků, do kterých se tavenina po odběru nalije a teploty tuhnutí se pak mmří například pomcoií termočlánku.At present, various shell molds are used for laboratory and process measurement of the pour point of the melt, into which the melt is poured after collection and the pour point is measured, for example, using a thermocouple.
Nevýhodou dosavadního stavu je především manipulace s odběrem taveniny, případně její uklidňování, dále pak malá přesnost měřených hodnot, například u ocelí s nízkým obsahem uhlíku.The disadvantage of the prior art is mainly the handling of melt collection or its calming, and also the low accuracy of measured values, for example for low carbon steels.
Uvedené nevýhody jsou zcela odstraněny sondou dle vynálezu, jehož podstata spočívá v tom, že sonda sestává z tvarové krytky s plnicím otvorem, na kterou navazuje automatický uzávěr natékání taveniny, přecházzjící do měřicího prostoru s čidlem pro přesné měření teploty.The above-mentioned disadvantages are completely eliminated by the probe according to the invention, which consists in that the probe consists of a shaped cap with a filling opening, followed by an automatic melt flow shut-off, which passes into the measuring chamber with a sensor for accurate temperature measurement.
Výhodou předmětné sondy je zejména vysoká přesnost stanovení teploty tuhnutí taveniny, rychlost stanovení a široká moonoot vyrážtí bez ohledu na druh taveniny, například v černé i barevné mejtlutgii, sklářství apod.The advantage of the present probe is especially high accuracy of determination of the melting point of the melt, speed of determination and wide moonoot, irrespective of the type of melt, for example in black and colored mejtlutgii, glass industry etc.
Příkladné provedení sondy dle vynálezu je znázorněno na připojeném výkresu v podélná osovém řezu.An exemplary embodiment of a probe according to the invention is shown in longitudinal axial section of the attached drawing.
Na čele ochranného pláště £ je tvarová krytka 1_, opatřená plnicím otvorem £. Na tento plnicí otvor £ navazuje automatický uzávěr' 2_ natékání taveniny, který přechází do měěicího prostoru £ s čidlem £ pro přesné změěení teploty taveniny.At the front of the protective sheath 4 there is a shaped cap 7 provided with a filling opening 6. This filling aperture 4 is followed by an automatic melt flow stopper 2, which passes into the metering chamber 4 with a sensor 6 to accurately change the temperature of the melt.
Při vlastní práci se sonda pomocí neznačeného nosiče ponoří do taveniny. Plnicm otvorem £ vnikne tavenina do vnitřního prostoru sondy, a to přes automatický uzávěr ' £ natékání taveniny, který po zaplnění měěicího prostoru £ uzavře další přítok - taveniny. Čidlo' £ změří teplotu taveniny a přes kontaktní část předá údaj vyhodnocovacímu zařízení. Odvod vzniklých plynů a vzduchu je zajištěn bud vnitřním prostorem ochranného pláště £ - nebo rneezvrstvami, případně je vyveden vně ochranného pláště ' £.During the work itself, the probe is immersed in the melt using an unlabeled carrier. The melt enters the inside of the probe through the filling opening 4 via the automatic shut-off valve 6, which, after filling the metering space 4, closes the next inflow - the melt. The sensor measures the temperature of the melt and transmits the data to the evaluation device via the contact portion. The evacuation of the resulting gases and air is ensured either by the internal space of the protective sheath (6) or by layers, or it is led outside the protective sheath (6).
Předmětné sondy lze výhodně vyuuit při měření teploty všech taventa, a to v černé i barevné meet^^gli, sklářském průmyyiu apod.The present probes can be advantageously used for measuring the temperature of all tavents, in black and color meet ^^ gli, glass industry etc.
