Definitions
- the invention relates to a device for cooling moving
- the invention relates to a method using the device and a UTMDF or UTHDF plate which has been cooled with the device.
- MDF stands for a medium density fiberboard or medium density
- Fiber board while HDF denotes the high-density fiberboard.
- the invention relates to sheet having a thickness of 1 to 5 mm and a density of 600 to 1200 kg / m3. At this point the thickness designation comes in the designation, the UT, to bear, the "Ultra Thin" characterizes
- double-belt cooling presses are known, by means of which an approximately 15 mm thick material plate can be subjected to shock cooling. From both
- Cooling stars have to be stored until they have reached a temperature at which they can be stacked, or the boards must be ground in similar installations because the surfaces are roughened.
- the object of the invention is therefore to provide a device with which a flat material according to the invention can be cooled without significant loss of quality, that it faster and more accurate
- the object is achieved according to the device that the
- the cooled strip or jacket has a significant influence on the forming surface quality of the sheet. If pressure or temperature can be adjusted zone by zone over the width of the sheet or in its machining direction, one can skilfully influence the profile. For example, it may be necessary to operate at drier marginal zones of the sheet at different pressures or temperatures than that applied in the center of the sheet. Bumps in the Flat material can also be compensated, for example in the transverse profile transversely
- Unevenness can occur due to variations in the scattering, so they are basis weight fluctuations. These are even in modern systems in the order of 10 kg / m 3 with a mean plate density of 860 kg / m 3 .
- the pressure in the individual zones can be controlled via a processor, for example, based on the thickness differences determined by a sensor.
- the element is a pressure element which presses the circulating belt or the rotating roll shell against the flat material.
- One thus possesses an element which is suitable for applying the base pressure to the tape or the jacket.
- the pressure element is provided within the cooling element to the circulating belt or the circumferential
- Pressure element can be adjusted in its elasticity and friction.
- the zones are narrower in the region of the flat material edge transversely to the running direction of the flat material than in the middle. This gives a finer Profiltechniksbaukeit the edge, where usually the largest deviations from the nominal profile occur.
- the zones comprise hydrostatic pockets.
- hydrostatic pockets can be used to simply build up a pressure which, in the case of two relatively moving parts (band or jacket to the element), greatly reduces the friction.
- the hydrostatic fluid can also be used for cooling. It is particularly preferred to ensure that the contact pressure can be generated via the pressure of the cooling fluid.
- pressure elements are used, which can be employed by one or more piston-cylinder units.
- the cooling fluid is passed under a pressure of 3 to 20 bar through one or more capillaries in a so-called pressure pocket, which is embedded on the tape or the jacket facing surface of the pressure element.
- Cooling fluid then flows over the framing webs of the pressure pocket and takes over two tasks. On the one hand, it provides for one
- frictionless fluid lubrication or gas cushioning which also absorbs the pressure on the sheet, and on the other hand, it cools the tape or sheath from the inside in direct contact.
- the length of the contacting surface of a circulating belt or a rotating roll shell is at most 2000 mm, preferably at most 1000 mm.
- Cooling element simplifies constructively considerably. Technologically, the sheet experiences some sort of short "pulse cooling" that has been found to be very beneficial to the overall cooling process, provided that the sheet has a speed of 1.0 to 2.0 m / s, the cooling pulses correspondingly take about 100 to 800 ms.
- a plurality of cooling elements are provided in series with at least one intermediate temperature compensation zone.
- this is an inlet temperature of approx. 100 ° C towards a temperature
- the temperature equalization zone is to be understood as a stretched section for the flat material, in which the surface temperature which is greatly reduced in the cooling element and the core temperature approach each other again.
- Vapor pressure equalization take place.
- the temperature compensation zone has a length of 100 to 2000 mm.
- the sheet is given the opportunity to lower the temperature gradient from surface to core again. The internal heat is thus led out with the opportunity of a moisture and vapor pressure equalization.
- Temperature compensation zone at least partially provided with a flat material towards open hood. This creates between the cooling elements a temperature compensation zones with a conditionable atmosphere near the surface of the sheet. It can "flash" -like evaporations are avoided and thus tearing and roughening of the surface.
- encircling belts are encapsulated and / or conditioned. This prevents condensation on the cold strips.
- a counter element This not only acts as a counterforce to the pressure built up by the cooling element against the flat material, but is also suitably designed as a cooling element. This results in a
- Symmetrical temperature profile over the sheet thickness and the heat accumulated inside can flow off in two directions.
- the counter element and the cooling element are constructed largely identical. It is still beneficial if all Cooling and counter elements are constructed substantially the same. This creates a module that has to be constructed only once depending on the fiber material width and finally, depending on requirements, can be used several times in succession.
- the band or the jacket has a wall thickness of at most 0.1 to 2 mm and at least the surface of the band or the jacket consists of metal. As a result, the heat dissipation is facilitated because of the high thermal conductivity of the sheath or strip material.
- a 0.2 mm thick strip of electroformed nickel has proven to be particularly effective here.
- the surface of the band or the shell has a roughness with a maximum Ra value of 0.8 ⁇ .
- the flat material is "calibrated" before it reaches the first cooling element, for which purpose it is provided that at least the first cooling element has a nip for the flat material
- rollers can be provided with adapted surfaces, so for example hard and smooth metal for
- rollers Producing a special smoothness, or with an elastic coating to achieve a uniform compaction.
- the rollers can be tempered.
- the object of the invention is achieved in that a cooling of at least 50 ° C takes place via the device described. And with respect to the product of a UTMDF or UTHDF plate having a thickness of 1 to 3 mm, the object of the invention is achieved by cooling it by means of the described device.
- the invention will be explained in more detail below with reference to an embodiment with reference to the drawings. 1 shows a schematic, partially sectioned illustration of a device according to the invention for cooling
- FIG. 2 shows a cross section through a cooling element
- Figure 3 is a three-dimensional view of a cooling element without tape
- Figure 4 is a diagram in which the temperature profile of the core and surface of a sheet over the treatment time is shown in the device according to the invention.
- the counter-elements 4' are constructed identically, as the cooling elements 4, so that the device has a plurality of similar modules.
- Both cooling element 4 and counter element 4 ' have a frame 8 in which two guide rollers 6 are mounted.
- the contact surface 5 is in this case by a circulating over the two guide rollers 6
- Metal band 7 formed.
- flexible roll shells would be conceivable.
- refrigerated elements 9 in particular pressure elements, stored, which will be described later.
- Cooling element 4 has at least one, not shown Connection for a cooling fluid. About the cooling fluid, the metal strip 7 on the side facing away from the flat material, so the inside cooled. In this way, the heat is removed from the surface area of the cooling fluid.
- the band has a very small thickness of, for example, 0.3 mm and is made of a good heat-conducting metal such as steel or better nickel.
- the temperature of the cooling fluid can be monitored and as soon as the cooling fluid in the sealed cooling element 4 a
- cooling device 1 In order to make the cooling device 1 according to the invention to be particularly effective, at least 10 cooling elements 4 should be connected in series (for illustrative reasons only four are shown in FIG. 1). If the metal band 7 also a
- Sheet 2 is in the temperature compensation zone 10, heat flows from the hotter core to the recently cooled surfaces of the sheet 2.
- the temperature compensation zone 10 is covered by a hood 1 1 to create a favorable, humid, so conditioned atmosphere, so it does not to Flashverdampfept and thus to a roughening of the surface of the sheet 2 comes.
- the temperature compensation zone 10 has a length of 100 to 2000 mm, in this embodiment about 900 mm.
- the temperature compensation zones prevent condensation of ambient air on the sheet 2 or the belt 7. Accordingly, in not illustrated manner, each band 7 be at least partially housed.
- the nip 3 is formed by two rollers 12, 13.
- the roller 12 is a roller with a bending over at least one support member 14 and engageable against the backing roll 13 jacket 15.
- the sheet 2 is also pressurized and smoothed or calibrated accordingly.
- the figure 2 is a cross section through each one against each other working cooling and identically constructed counter-element is placed.
- Circumferential metal strip 7 presses the (pressure) element 9, which is supported on the frame 8.
- zones 16 are introduced.
- formed zones 16 are supplied with pressurized cooling fluid, so that builds up a pressure cushion between element 9 and 7 band.
- the contact pressure can therefore be generated via the pressure of the cooling fluid.
- a plurality of narrow zones (pockets 16 ") are provided in the region of the edges of the flat material 2, while the zones (pockets 16 ') in the middle of the flat material can be larger. The purpose is to apply pressure and cooling to the often drier or thinner edges of the substrate Flat 2 can set more accurate, then to a
- the spring 17 acts on the edge even in the opposite direction to
- the cooling element 4 is shown in three dimensions.
- the tape 7 was not drawn.
- the pocket division of the zones / pockets 16, 16 'and 16 "in the pressure element 9 is better illustrated.
- the technological mode of operation of the device according to the invention can easily be demonstrated with reference to the diagram in FIG. 4 with reference to a practical example.
- the temperature is plotted over the cooling time.
- the curve A stands for the core temperature of the sheet 2 and the curve B shows the temperature profile at the surface.
