Definitions

  • the present invention relates to an improvement made to devices for the heat treatment of moving wires and in particular, the heat treatment of wires in order to give them certain shrinkage properties and / or bulkiness and / or elasticity.
  • the new type of oven according to the invention for the heat treatment of a wire for example during a texturing stretching operation, is of the type constituted by an insulating enclosure which surrounds a heating block comprising a longitudinal channel inside which passes the wire to be treated, means for guiding said wire being provided upstream and downstream of the oven to ensure its positioning, and it is characterized in that said channel has a section such that on part of its length, the wire circulates inside the wall, its temperature rise being obtained by radiation in this area and that, in the remaining part of the oven, it comes into contact with said wall, the transmission of heat is then produced by contact (or conduction).
  • the heating element proper is in the form of a cylindrical block, pierced along its length with a channel which is also cylindrical, the contact heating zone being obtained by arranging at inside said channel a profile, good conductor of heat, which bears against the internal surface of the conduit and which has a bearing surface for the wire arranged substantially along the axis of said conduit.
  • the heating block is made of ceramic (or any other equivalent material), resistors being embedded in the wall.
  • the profile serving as a bearing surface is, for its part, made of all materials which are good conductors of heat, such as stainless steel, ceramic or other materials.
  • Such an oven can be either completely closed or have a longitudinal slot (so-called "open” oven).
  • the length can be between 0.30 meter and 1.50 meter, the temperature between 300 and 1000 ° C.
  • the length of contact heating will advantageously be between 25 and 75% of the total length of the oven.
  • the passage of the wire can be either straight, or possibly curved, by adapting the shape of the profile.
  • the heating element of the oven consists of an insulating enclosure (13), shown schematically in phantom in Figure 1 and a block (1) , ceramic (or other equivalent material), and which is pierced over its entire length with a circular section conduit (2) which can be either closed, or have a longitudinal slot as illustrated in Figure 1 attached.
  • Guide elements (3,4) for the wire (5) are arranged upstream and downstream of the block.
  • the heating elements are arranged in a known manner inside the wall of the block (1). These heating elements can either communicate a regular temperature over the entire length of the oven, or possibly allow zones to be brought to different temperatures.
  • the internal section (2) of the axial duct is such that in a zone (A), the wire (5) is kept at a distance from the internal wall (6) of the duct (2), while in another zone (B), the wire (5) is heated by contact.
  • the contact heating zone (B) is obtained, in the illustrated embodiment, by inserting a deep-drawn profile (7) inside the duct (2).
  • a profile (7) for example made of stainless steel (or any other equivalent material such as ceramic), has a section such that it bears regularly against the internal wall of the duct (6) and that it has a surface (8) arranged substantially along the axis of travel of the wire (5).
  • This bearing surface (8) can be either rectilinear or possibly be curved.
  • the lower face (8) in contact with which the wire (5) is located can be flat, preferably it will be curved (the section of the stamped element having substantially the shape of a "bean"), which favors the positioning of the wire when it travels, in particular when the latter is produced at very high speed.
  • Such an oven design is particularly suitable for making texturing machines, in particular by false twist, compact, as illustrated in FIG. 3.
  • the oven according to the invention designated by the general reference (F) is arranged between a feeder (10) for the wire (5) and a cooling zone (11) followed by a false twist spindle (12).
  • the oven (F) is, in such a case, designed as illustrated in FIGS. 1 and 2 so that in the entry zone (A), the wire is heated by radiation, while in the exit zone (B ), it is heated by conduction.
  • such an oven (F) may have a length of between 0.3 and 1.5 meters, the temperature between 300 and 1000 ° C. and the diameter of the internal conduit (2) possibly being twelve millimeters.
