Abstract
Description
- The subject of the invention is a furnace for testing materials associated with a characterisation method using said furnace.
- A thermal test for characterising materials relates to their resistance to self-ignition under the effect of external heating. A specimen of a material may be placed in an enclosure and subjected to a conventional heating, such as a temperature ramp as a function of time or a temperature holding period for a determined time. The measurement may be visual, the specimen being observed until a flame or an ember appears, or consist in a measurement of the temperature of the specimen which indicates the additional temperature attained compared to the temperature applied.
- Several embodiments of the test exist. One of them uses a powder specimen laid in a layer on a heating plate subjected to a temperature holding period of 30 minutes. The test is considered as positive when the appearance of an ember, flame or a rise in temperature of at least 250 degrees Celsius is observed in the layer compared to the holding period temperature.
- A second test embodiment uses a Goddert-Greenwald furnace which mainly comprises a vertical cylindrical tube heated by a resistance to the desired temperature. The powder specimen is laid in a horizontal tube communicating with the vertical cylinder. A high pressure system blows a cloud of powder into the vertical tube. The test is positive if flames appear.
- Finally, a third test consists in placing a specimen in a steel basket which is placed in a furnace. The desired temperature is established in the furnace. The test is considered as positive by convention when the temperature of the specimen exceeds 400 degrees Celsius.
- The very variety of these furnaces and the criteria retained to evaluate the self-ignition temperature bears witness to the arbitrariness of this measurement. Above all, it is not certain that the self-ignition should be related to the overall conditions in the material, since it can often proceed from shocks or other mechanical interactions having dissipated the energy in a small volume.
- There exists a certain number of furnaces, of which the documents EP A 1,132,733, U.S. Pat. No. 3,987,661 and U.S. Pat. No. 3,718,437 give examples, which describe furnaces provided with overall heating means, which act on the specimen indirectly by heating firstly, and rather uniformly, the gaseous medium surrounding the specimen.
- A furnace of a novel kind is proposed according to the invention.
- It relates to a furnace for testing materials comprising an enclosure, a tray for receiving specimens of materials, above said tray first adjustable, overall heating means, which are spread out on the periphery of the enclosure, and second heating means, housed in the tray and passing through the surface of the tray so as to be in contact with the specimen, extending up into a place where it is received.
- The second heating means have a heating intensity adjustable independently of the first means and have a defined geometry (shape and dimension) in order to apply according to the desired conditions an additional energy directly to the specimen independently of the ambient temperature in the enclosure, controlled by the overall heating means. In this way, more realistic conditions are available to characterise the thermal behaviour of materials with heating and particularly their aptitude to self-ignition, the second heating means being able to have a reduced surface area to simulate local heating, safeguarded by the direct contact between them and the specimen.
- Advantageously, the tray forms part of the enclosure, which is also composed of a bell laid on the tray and separable from the tray, the overall heating means are spread out particularly on the tray and around at least one lower part of the bell, and the second heating means extend beyond the upper surface of the tray.
- Such an embodiment with bell and tray is particularly simple to manufacture and handle, which makes it useful for the study of radioactive materials through a glove box or any other protective wall. The spreading of the first heating means procures a uniform heating of the specimen, and the second heating means act in the very interior thereof, which may represent a more realistic test.
- Greater security is offered if the furnace comprises screws to unite the bell to the tray, and springs assembled against the screws to tolerate a spreading between the bell and the tray in the event of high pressure in the enclosure.
- Finally, the invention relates to an original method of measuring the self-ignition temperature of a specimen. It consists in evaluating the effect of a mechanical energy on the tendency to self-ignition of the material by evaluating a quantity of energy dissipated in the material with a mechanical energy, in placing a specimen of the material in the furnace defined above, and in applying the quantity of energy to the specimen by the heating means of defined dimension, before observing or measuring the effect on the specimen.
- The invention will be described by means of
FIGS. 1 and 2 , which correspond to two views of the furnace in oblique view and side view andFIG. 3 , which represents more schematically the furnace in section. The furnace is firstly composed of a stainless steel bell 1 with threeviewing ports 2 equipped with cooled glass, below which is atray 3, the vertical movement of which is controlled by an electric motor 4. Thetray 3 bearsvertical columns 20 on which slide asupport 21 of the bell 1, and the motor 4 makes aworm screw 22 turn which raises or lowers thetray 3 by an ordinary kind of transmission. Thetray 3 may thus be pressed against the bottom of the bell 1 or separated from it. Between the bell 1 and aprotective hood 5 that surrounds it are installed anelectrical resistance 7 adjacent to the bell 1 and aninsulating layer 8 adjacent to thehood 5. Theresistance 7 is a winding strip extending at least to the lower part of the bell 1. Theinsulating layer 8 extends all around the bell 1, and above it. Thehood 5 is cooled by afluid circuit 6 extending on the peripheral face and summit thereof. Thetray 3 comprises anelectrical resistance 9 in planar form extending over a part of the surface thereof and, at the centre, a localelectric resistance 10. Theelectrical resistances tray 3 and the bell 1, and the localelectrical resistance 10 constitutes a second heating means that is exerted on a small, localised volume, of the specimen laid on the tray. It may consist in a pointed filament passing through the upper surface of thetray 3, flush with it or extending upwards from it to a place such as areceptacle 22 where the specimen is received by being laid on this upper surface. These heating means are adjustable and independent. Through thetray 3 also traversethermocouples 11, a conduit for extractinggases 12 equipped with apressure sensor 13 and asafety valve 14, a pipe for supplyinggases 15 equipped with a flow regulator, not represented. Thesupply pipe 15 is intended to fill the enclosure with the gas desired for the test. During closing, thetray 3 seals the bell 1, and threescrews 16, borne by thesupport 21 of the bell 1 and screwed into thetray 3, make it possible to seal the enclosure in a leak tight manner. Springs 17 are nevertheless assembled against thescrews 16 so as to enable the opening of the bell 1 in the event of high pressure of the gases, which compresses saidsprings 17. The furnace is equipped with devices for acquiring normal data such as recorders of the internal pressure, temperatures of the specimen and the enclosure, as well as an optical pyrometer, a camera and a flow regulator. The device may be completed by gas analysers at the outlet, a generator of humid gas, a thermal camera, etc. All of these devices are centralised on a computer close to the work station and which carry out the desired temperature regulation. Means of lighting the enclosure are provided. - The furnace may be placed in a glove box that receives the fluids necessary for the test, as well as the specimens of materials and auxiliary means such as a balance enabling the specimens to be weighed, and other sensors. The volume of the enclosure may be around 5 litres and the temperature applied may reach up to around 500 degrees Celsius. The safety valve may be tared to 3 bars and the
springs 17 for opening the enclosure to 5 bars. Finally, the wall of the enclosure has been dimensioned and tested for a pressure above 10 bars. The pressure sensor may trigger an automatic stoppage of the heating as soon as a pressure such as 1.5 bars is reached. - A test may be undertaken in the following manner. A specimen 23 of material to be tested is placed in the enclosure, for example in the
receptacle 22 formed at the centre of thetray 3, and the enclosure is closed by raising thetray 3. The sealing is ensured by acircular seal 24 completed by an adjacent cooling means, which are not represented but may further comprise a liquid coil. The overall heating means composed ofelectrical resistances electrical resistance 9 on thetray 3, beside the specimen 23, does not heat it directly. When a mechanical interaction dissipating energy in the specimen has to be simulated, its quantity of energy is evaluated by calculation, empirically, or otherwise, and it is delivered by the localelectrical resistance 10. This application of heat is much better for simulating a mechanical interaction since it is made in actual contact with the specimen, such as a rubbing or a shock, and since it is exerted on an area of defined dimension, which is often true again for mechanical interactions. The judgement on the result of the test is then obtained by applying a criterion chosen by the user, such as those already proposed: optical examination of the specimen on measuring its rise in temperature. - The second heating means may have another form or another surface area, such that the invention is not limited to a localised heating. It may pass through the upper surface of the
tray 3 to extend beyond it to be inside the specimen 23 when it is powdery or divided, or to be flush with this surface to end up in contact with the surface of the specimen, especially when it is solid.
