Definitions
- the invention relates to the manufacture of flat glass (or plane) by floating, said glass being a precursor glass-ceramic.
- Vitroceramics are silica-rich materials comprising at least one crystalline phase and obtained after a ceramizing heat treatment from a precursor glass (or parent glass). Vitroceramics have a very low coefficient of linear expansion, generally less than 15.10 "7 K " 1 .
- the glass-ceramic may comprise at least 50% by weight of silica.
- An important family of glass-ceramics is that comprising both SiO 2, Al 2 O 3 and Li 2 O for which the ceramization treatment leads to crystals of beta eucryptite or beta spodumene or beta quartz.
- vitroceramics translucent or opaque, find use particularly as hotplates or fireproof plates, and more generally in uses requiring a very low coefficient of expansion glass.
- Vitroceramics have the disadvantage of having a strong tendency to devitrification when hot, which usually results in many maintenance interventions of the forming facilities. Indeed, the plates or sheets of glass-ceramics are usually made by rolling between metal rollers and devitrification deposits damage the surface of said rollers. These must be periodically rectified (even every 2 to 3 days) or replaced. The glass-ceramic forming installations are therefore usually designed to make maintenance operations easy, which implies a great accessibility to the rolling rolls, even during the manufacturing process.
- vitroceramics in gigantic installations whose core remains inaccessible during operation as is the case with glass floating installations. Indeed, these installations are several tens of meters or even several hundred meters in length for several meters in width and the transition times to start and stop are considerable. Such installations must therefore operate permanently and a stop for maintenance is catastrophic and prohibitive.
- Conventional glass-lamination vitroceramics forming plants do not also make it impossible to make very wide leaves. The width is limited to less than 700 mm. However, today we need plates of larger widths. Similarly, this rolling method does not allow the production of very thin sheets with a thickness of less than 3 mm.
- WO2005 / 073138 recommends the removal of fixed points of float glass, in particular by pouring molten metal, which requires the installation of special pipes for molten metal.
- US 3684475 teaches the passage of a strip of laminated glass on a metal bath. So there is no spill of molten glass. Such rolling at these very high temperatures does not make it possible to obtain large and / or thick glass sheets.
- US2002 / 0023463 teaches a particular glass ceramic composition capable of being floatable without surface crystallization. This document notably teaches that a depletion in ZnO on the surface generates a devitrification. The glass remains floating for a long time (30 to 40 minutes) so that the cooling rate of the glass is below 18 ° C / min.
- the glass is cast at a temperature above its devitrification start temperature, and b) the cooling rate of the glass is at least 18 ° C / min between firstly the moment t1 or the glass is at the maximum speed of devitrification temperature, and secondly the moment t2 (t2 coming after the moment t1, that is to say that t2 is subsequent to t1) or the glass is at the temperature at which the growth rate of devitrification crystals becomes less than 1 micrometer per minute.
- Conditions a) and b) above use devitrification parameters (temperature and crystal growth rate), whereas precisely no devitrification takes place thanks to the process according to the invention. This is why we can also talk about theoretical temperatures. In fact, it is necessary to determine these parameters in advance before operating the process according to the invention, by carrying out devitrification tests on samples of the desired composition. Indeed, these parameters may vary depending on the composition of the glass. To determine them, glass samples are placed in crucibles which are heated to a sufficiently high temperature so that no devitrification can take place (generally 1500 0 C and even 1400 0 C are sufficient), it is allowed to cool down until at a temperature T at which a plateau of a duration t is observed, and is rapidly cooled. By varying T and t, it is possible to determine the devitrification start temperature and the devitrification speed.
- the DSC can also be used to know the maximum temperatures and speeds of devitrification.
- the crystal sizes in the samples are determined by visual observation under a binocular microscope. The moment t2 is after the moment t1.
- the cooling rate of the glass is at least 18 ° C / min between the moment t1 and the moment t2.
- This speed, between t1 and t2 is generally less than 48 ° C / min and may even be less than less than 40 ° C / min, or even less than 30 ° C / min, or even less than 28 ° C / min.
- a slightly reducing gaseous atmosphere is maintained in the float chamber, for example an N 2 / H 2 mixture containing from 1 to 12% of hydrogen (in normal volume or N 1).
- the gaseous atmosphere is generally renewed in the floating chamber at a rate of 3 to 250 times per hour.
- the metal bath is at about 1000 ° C.
- the molten metal it is generally necessary for the molten metal to be more than 1150 ° C. and even more than 1200 ° C. C and even more than 1250 0 C, on the surface at the place of the casting. Good results have been obtained with a temperature of 1250 ° C. measured at 3 cm below the molten metal surface at the point where the glass is cast, which means that the temperature is higher than the surface itself.
- the glass tends to drive the metal downstream as well.
- the metal returns upstream by a deeper current, this movement being generally described as a circulation loop.
- the molten metal also fall in temperature from upstream to downstream. That is why, instead of having a single loop of molten metal circulation between the downstream and the upstream, it may be preferable to have at least two successive loops of circulation on the way to the glass, thanks to a dam embedded in the molten metal in an intermediate zone of the bath.
- This dam may in particular be molybdenum coated with a protective layer, for example alumina.
- a protective layer for example alumina.
- the evolution of the temperature from upstream to downstream is regulated from the heating elements placed above the glass throughout installation. It is generally sought that at the point where the glass separates from the metal (contact point glass / molten metal furthest downstream), the glass has a temperature of between 730 and 850 0 C. Preferably, one sinks the upstream glass at a temperature such that the decimal logarithm of its viscosity in poises ranges from 3.4 to 3.9. Preferably, at the point where the glass separates from the metal (glass / molten metal contact point furthest downstream), the glass has a temperature such that the decimal logarithm of its viscosity in poises is from 11 to 12.
- the precursor glass In the conventional laminar glass-ceramic manufacturing process, the precursor glass generally contains arsenic in oxidized form as a refining agent.
- the presence of arsenic in the precursor glass to be converted according to the invention is disadvised because the gaseous atmosphere of the floating installation could then be charged with toxic gas.
- SnO2 another refining agent
- the precursor glass may thus comprise 0 to 0.5% by weight of SnO 2.
- the precursor glass preferably contains less than 100 ppm by weight of AS2O3.
- the precursor glass may not comprise antimony or comprise less than 100 ppm by weight of Sb 2 O 3 .
- the precursor glass may not include tin.
- it may be a glass whose composition is that claimed in French Patent Application No. 0554052 (whose content is included by reference), that is to say a glass with the following composition:
- the precursor glass may, however, contain tin in oxidized form, playing in particular the role of refining.
- the SnO 2 content then ranges from 0.1 to 0.5% by weight. It was observed that the face in contact with the metal enriched with tin. In one test, it was observed in particular that the SnO 2 concentration increased over a depth of 150 nm to go from 0.2% by weight to less than 150 nm in thickness to 10% by weight on the surface. After floating according to the invention, the glass has a SnO 2 surface gradient whose content decreases toward the core of the glass.
- the SnO 2 concentration passes locally by a concentration of at least 5% by weight, or even at least 8% by weight, and generally at most 12% by weight. weight.
- the increase of the surface mechanical resistance, measured by indentation, on the glass-ceramic, which may be due to this enrichment is illustrated by the examples below.
- vitroceramics of the same composition were compared, one being produced according to the invention, the other being produced by the conventional rolling method. These vitroceramics both had a global composition:
- the glass may comprise ZnO, generally up to 3.5% by weight.
- the process according to the invention reduces the surface content of ZnO on the side in contact with the gaseous atmosphere (not that in contact with the metal bath).
- a glass containing at heart for example in the middle of the thickness of the glass
- ZnO saw its concentration gradually reduced to 0% at the surface, while more than 10 microns, the ZnO content is 2% by weight.
- this impoverishment on the surface did not translate into less devitrification, contrary to the teaching of US2002 / 0023463.
- the precursor glass and the vitroceramic which derives therefrom may not contain dye.
- Transparent glass-ceramic is needed especially for chimney inserts and fire doors.
- the glass-ceramic must be opaque in the visible range but as transparent as possible vis-à-vis the infrared.
- the glass hob hides the heating elements under it, but allows as much heating radiation as possible for cooking (the heating elements nevertheless become visible through the glass ceramic hob as soon as they are heated). are red).
- at least one of the following coloring agents may be added in the glass composition:
- NiO up to 1% and more generally 0.2 to 0.9% by weight
- Cr 2 O 3 up to 1% and more generally 0.2 to 0.9% by weight
- V 2 O 5 is a preferred coloring agent because it makes it possible to endow the final glass ceramic with specific properties which are particularly sought for an application as a hob.
- V2O5 gives the glass ceramic a low visible transmission and high infrared (IR) transmission.
- the low visible transmission means that the user is not dazzled by the underlying heating elements, and the high infrared transmission makes it possible to visually detect the heating element while it is in operation and to facilitate adjustment. cooking conditions.
- Vitroceramics loaded with a dye have the disadvantage of having their color change slowly over time, which is generally related to a change in the degree of oxidation of the dye. This unwanted aging results in a change in color at the places that have been most heated during use.
- heating repeated by the resistors always in the same places, causes the formation of visible marks taking the form of said resistors.
- V 2 O 5 dye it is the slow evolution towards V 3 O 2 which causes the formation of darker marks.
- Aging resistance can be tested by accelerated heat treatments involving higher temperatures than the intended use would have done. A typical test is 1000 hours of heating at 725 ° C, after which the capacity of the glass-ceramic to transmit IR is measured.
- the invention also relates to a vitroceramic precursor glass plate comprising a multivalent dye element having, uniformly on at least one main face of said plate, a more reduced surface-to-core state, said main face having an area of at least 100 cm 2 and possibly even greater than 200 cm 2 and even greater than 400 cm 2 .
- the reduced state goes from the surface to a depth ranging from 100 to 300 ⁇ m.
- the invention also relates to a vitroceramic plate comprising a multivalent dye element having, uniformly on at least one main face of said plate, a state which is smaller in area than at its core, said main face having an area of at least 100 cm. 2 and may even be greater than 200 cm 2 and even greater than 400 cm 2 .
- the cooling rate between moments t1 and t2 was 25 ° C./min.
- the floating of the glass according to the invention leads to a glass which is not yet a glass-ceramic, but it should be converted into an additional step well known to those skilled in the art. Indeed, the particular structure of glass-ceramic is achieved by a specific heat treatment
- ceramization posterior to forming sheet / plate and even generally posterior to the longitudinal and transverse cut of the float ribbon.
- the ceramization treatment can generally be carried out as follows: a) raising the temperature at a rate of 30 to 80 ° C / minute to the nucleation range, generally located in the vicinity of the glass transformation area; b) crossing the nucleation interval (670 - 800 0 C) in 15 to 25 minutes; c) raising the temperature at a rate of 15 to 30 ° C./minute up to the temperature of the ceramic bearing generally between 900 and 1100
- the glass plate contains the crystalline phase characteristic of the glass-ceramic structure.
- the plates obtained After cutting the tape (ceramized or not), the plates obtained have two main surfaces (and a slice of 4 small surfaces) whose area is greater than 100 cm 2 and generally greater than 1000 cm 2 .
