Definitions
- the invention relates to a method for convective heat transfer between a heat transfer medium and the end faces of a wound metal strip in the form of a coil, wherein the end faces of the metal strip are acted upon by means of at least one rotatable nozzle wall with the heat transfer medium.
- the invention further relates to an apparatus for carrying out the method for convective heat transfer between a heat transfer medium and the end faces of a wound metal strip.
- German Patent 35 03 089 C2 is a device for uniform loading of a flat surface of a workpiece with a gas known.
- the surface of the workpiece is in particular the end face of a cylindrical band collar.
- the admission of the gas takes place via slot-shaped nozzle openings in a nozzle bottom, wherein the nozzle openings are at an angle to the surface of the band.
- German Patent 196 50 965 C1 is a device for uniformly applying a flat surface of a workpiece with a fluid known.
- the surface of the workpiece is preferably also the end face of a cylindrical band collar.
- the nozzle bottom for the application of the fluid is designed such that at the nozzle openings means for deflecting the nozzle jets are provided in a direction which forms an angle with the perpendicular to the nozzle bottom or at a substantially plane nozzle bottom with its planar reference surface.
- the object of the invention is therefore to provide a method for convective heat transfer between a heat transfer medium and a surface, in particular the front side of a metal strip in the form of a wound cylindrical coil, through which the most uniform and high heat transfer is realized, without causing adverse effects Workpiece comes.
- the object of the invention is also to provide a device for carrying out the method.
- this object is achieved in that in the convective heat transfer between a heat transfer medium and the end faces of a wound metal strip in the form of a coil both end faces of the metal strip are acted upon by the heat transfer means by means of a respective rotatable nozzle wall with the heat transfer medium, wherein the heat transfer medium through a plurality of nozzle openings Nozzle wall flows and move during the heat treatment both nozzle walls and the end faces of the metal strip to each other.
- a generic device for convective heat transfer between a heat transfer medium and the end faces of a wound metal strip in the form of a coil means for acting on the end faces of the metal strip are provided with the heat transfer means by means of at least one rotatable nozzle wall, wherein on both end sides a rotatable nozzle wall is arranged in each case of the metal strip, and a nozzle wall has a plurality of nozzle openings, and both nozzle walls and the end faces of the metal strip are movable relative to one another during the heat treatment.
- the nozzle walls are movable while the coil is fixed, or a design includes both movable nozzle walls and moving coils.
- a design has been selected in which the nozzle walls are movable during the heat treatment and the coil is fixed.
- a chamber furnace of known design is equipped so that at the two end faces of an inserted cylindrical coil each have a nozzle wall which is rotatable about an axis of rotation, wherein the axis of rotation preferably corresponds to the major axis of the cylindrical coil or substantially parallel to this.
- the term "substantially” includes angles of the order of 0 ° and 10 °.
- the rotatable nozzle walls are provided with a plurality of nozzles whose arrangement and design is suitable for the purpose selected. For example, known hole, tube, slot and / or twist nozzles can be used.
- a gas is conveyed as a heat transfer medium via a pressure box in the nozzle walls and flows through the nozzles on the end faces of the coil to be heated or cooled. Due to the rotation of the nozzle walls, the two end faces are uniformly charged with the gas, so that a very good heat transfer is ensured on the surface. Furthermore, due to the uniform application, there are no local temperature peaks or sinks at which areas of the workpiece to be treated are overheated or undercooled.
- FIG. 1 is a section through a particularly preferred embodiment of a device for convective heat transfer between a heat transfer medium and a surface, in particular the end face of a wound metal strip in the form of a cylindrical coil shown.
- a heat transfer medium a fluid or a gas may be used.
- a gas is used for heat transfer.
- the device comprises a pressure box 20 into which the coil 30 to be heated or cooled is introduced.
- the coil is a cylindrically wound metal band.
- the metal strip shown is wound around an axis 70, which runs horizontally in the figure, so that plane surfaces result on the end faces 31 and 32 of the coil.
- a nozzle wall 10 and 11 is located substantially parallel to these end faces of the coil.
- the mobility of the nozzle walls and the end faces of the coil to each other is achieved in the illustrated embodiment by movable nozzle walls, while the coil is fixed during the heat treatment.
- the nozzle walls 10 and 11 are rotatable about a rotation axis 71, which preferably corresponds to the main axis 70 of the cylindrical coil 30 or extends substantially parallel thereto.
- the rotation of the nozzle walls via a drive 40, the in Fig. 1 is not shown in detail, but is characterized by ellipsoid motion arrows.
- the gas for heating or cooling of the coils are introduced into the pressure box 20.
- the gas may be different types of gas suitable for the particular application.
- N 2 , N 2 H 2 , air, water vapor, inert gas, hydrogen, exogas, or endogas can be used.
- the flow of the gas within the pressure box is indicated graphically by arrows.
- the gas flows through the nozzle walls 10 and 11 on each one end side of the coil.
- the nozzle walls have for this purpose a plurality of openings, which may be formed differently.
- slot nozzles 50 were selected, as shown in the figure Fig. 2 can be seen.
- the gas flows out of the nozzle openings and bounces on the front sides of the coil, where the heat transfer takes place. This applies both to the heating and to the cooling of the coil material.
- the seal can be adapted to the requirements in various ways.
- the sealing gap can be low or the seal can be designed as a labyrinth or contact seal.
- Fig. 2 is a plan to refer to a pressure chamber 20 with a circular nozzle wall 10.
- the rotating nozzle wall is designed in this embodiment with slot nozzles 50.
- other types of nozzles such as perforated, tubular or swirl nozzles can be used.
- Pipe nozzles may be provided, for example, with an inner swirl body, as in Fig. 4 is shown.
- FIG. 3 In the picture in Fig. 3 is a particularly preferred embodiment of a chamber furnace with integrated erfindunmonuxer device for heat transfer shown.
- the pressure box 20 is located within the furnace and a coil 30 to be heated or cooled is positioned between the two nozzle walls 10 and 11.
- the charging of the furnace with a coil takes place in this embodiment from below, which is shown graphically below the chamber of the furnace by dashed lines.
- the control of the chamber furnace preferably takes place via control means with a program which expediently controls and regulates at least the temperature and the speed of the heat transfer medium in such a way that the best possible heat transfer is achieved. If an embodiment is selected with nozzle walls that are movable along their axis of rotation, the distance between the nozzle wall and end face of the coil can also be controlled and regulated so that the best possible flow adjusts.
- FIG. 4 A preferred embodiment of one of the nozzles arranged in the nozzle walls 10, 11 is shown in the form of a pipe nozzle 81 with a swirl body 82 arranged therein.
- the inventive design of a device with nozzle walls which are designed to be movable to the end faces of the coils to be heated or cooled, has various advantages.
- uniformly charging the coil with the gas there are no temperature peaks or sinks, which could lead to a deterioration of the coil material.
- the uniform loading of the coil with the heat transfer medium also leads to a better heat transfer than in conventional systems, whereby the residence time of the workpieces can be lowered in the ovens. This allows energy savings and a reduction in throughput times.
- the installation of a separating nozzle box additionally improves the degree of utilization of the system.
