Description
Technical field
The utility model belongs to fire resistive material technical field of measurement and test, mainly proposes a kind of refractoriness auto testing instrument.
Background technology
Refractoriness is that fire resistive material is being resisted high temperature action and infusible character constantly without loading.It is an important technology index that characterizes fire resistive material high-temperature behavior; The test philosophy of general refractoriness is in the world at present: test material is made to butt pyrometric cone, the curved temperature of falling when curved fall occurs test cone in being subject to thermal process, that is: pyramid tip is curved while encountering afterwards frustum surperficial, and the temperature of residing environment is this material refractoriness.According to this principle, formulated corresponding fire resistive material refractoriness method of testing standard in the world.As; In < < GB/T7322-1997 fire resistive material refractoriness test method > > standard, with regard to reading of testing tool and refractoriness, made associated description.Thereby the temperature that its core part is how at high temperature to find that pyramid tip is curved and just encounters the surperficial moment cone environment of living in of frustum is measured the refractoriness of material accurately.
In existing refractoriness testing tool, the most representative instrument has two classes.The measuring technology that first kind instrument is core based on standard pyrometric cone is researched and developed, adopt the method for test cone and standard cone reference, contrast to determine the refractoriness of tested sample, during test, the standard pyrometric cone of the test cone of fire resistive material and known refractory degree is planted on frustum, under defined terms, the curved situation of heating comparison test cone and standard cone represents the refractoriness of test cone; This kind of test be take standard cone as reference, the error of getting rid of temperature sensing means, it is a kind of refractoriness testing tool being popular, at home and abroad promoted, but along with its drawback of development of refractoriness measuring technique also shows especially out gradually: first, the temperature range of act.std pyrometric cone is to have (1220 ℃～1580 ℃ or 1500 ℃～1800 ℃) that define, and does not just have standard pyrometric cone to use outward, let alone the contrast test of refractoriness in this scope; Second, the verification of the thermometric of standard shown in standard pyrometric cone is disposable, cannot reproduce, it for certain specific standards pyrometric cone, is not an exact value, it follows statistical law, is a typical value, has deviate (± 5K or ± 6K), and the temperature interval of two adjacent standard cones is 20 ℃, just determined that the accuracy level of its data is limited; The 3rd, because every less important standard cone of taking compares, therefore each test can only complete the test of a sample refractoriness at most, so not only efficiency is low but also energy consumption is high.Therefore, there is take the Equations of The Second Kind tester that non-standard pyrometric cone is temperature survey core,, in trial furnace, arrange thermoelectricity occasionally other temperature measuring equipment be temperature sensor, directly record in trial furnace the curved temperature value during to its most advanced and sophisticated contact frustum surface of test cone on temperature cone frustum, and by temperature control system, imaging system, data processing and the register system being connected with experimental furnace, realize the refractoriness tester of test, demonstration and the record of fire resistive material refractoriness.This kind equipment adopts the refractoriness of the direct testing experiment cone of thermopair, by imaging system, be connected in real time temperature and the curved situation of monitoring, record test cone place with computer, there is the features such as thermometric is accurate, automaticity is high, test process can reproduce, be therefore more and more subject to the favor of each scientific research institutions and refractory materials manufacturing enterprise.The difficult point of this kind equipment is on imaging technique, because test cone at high temperature, burner hearth, it is aglow that heater is burnt substantially, how to make test cone curved to fall that situation is at high temperature clearly observed and is recorded be that this kind equipment can be realized accurate key of testing, the technology of current comparative maturity is, test cone is equidistantly formed a line and is positioned in burner hearth together with frustum on frustum, the heater of arranging in the behind of test cone, with heater light as a setting, the light that during observation, test cone sends heater blocks, present the shade of test cone, thereby the state that makes test cone is presented in imaging system, this kind of direct-reading method refractoriness tester is because it is energy-conservation, efficient, the feature accurately of testing will lead the trend of refractoriness measuring technology development, but this imaging technique using at present does not reach optimal effect on imaging definition, this will exert an influence to the test result of refractoriness, and therefore a kind of brand-new imaging research and development more clear, that test the direct-read refractoriness tester of better effects if having just been put on schedule.
