Application of high frequency induction heating machine in fiber optic cable manufacturing

   High frequency heating machine - full name "high frequency induction heating machine", also known as high frequency induction heating equipment, high frequency induction heating device, high frequency heating power supply, high frequency power supply, high frequency welding machine, high frequency induction heating machine, high frequency induction heater (welders), etc., which is mainly induction heating of metal (non-contact); can quickly heat the metal, has the advantages of power saving, small size, easy installation, easy operation, safe and reliable, fast heating speed, etc. metal very quickly, with the advantages of power saving, small size, easy installation, easy operation, safety and reliability, fast heating speed, etc., the application range is very wide.


  After the emergence of fiber optic communication technology, optical technology began to penetrate the entire communication network, fiber optic communication has the trend of advancing to all-optical network. The market is the lifeblood of the industry, the price is the lifeblood of the enterprise, how to reasonably reduce product costs, improve product quality, to ensure that the user use requirements, is the top priority of the enterprises. This article introduces the traditional fiber optic cable ladle injection method and the new process - high frequency induction heating comparison.


  First, the principle of introduction


  As we all know, the permeability of fiber optic cable is an environmental performance index strictly required by the users, and the steel ladle structure of fiber optic cable in the steel lap is easy to permeate, the traditional way is generally used to hot melt glue injection, so that the steel lap completely bonded to prevent water seepage. However, there are many disadvantages of the traditional way, such as insufficient amount of glue will cause water seepage, too much glue will cause the sheath extrusion when the package occurs, so it is difficult to control the amount of glue; high-frequency heating machine which is good in addition will also be because of the steel belt surface polyester film bonding is not firm in the die core at the accumulation and cause the sheath out of the package phenomenon. The new process uses high-frequency induction heating principle to melt the steel strip surface film, which not only makes the steel strip lap bonded firmly, but also improves the bonding strength between the steel strip and sheath, solving the problem of water seepage and the sheath out of the bag phenomenon. The principle of high frequency induction heating is that the dielectric material under the action of high frequency electric field molecular phenomenon, and according to the electric field direction, because the high frequency electric field to change the molecular direction at a very fast rate, then the dielectric material will be heated due to dielectric loss. The high frequency current flows to the heating coil (usually made of purple copper tube) which is wound into a ring or other shape. As a result, a strong magnetic beam is generated in the coil, and the heated material such as metal is placed in the coil, the magnetic beam will pass through the whole heated material, and a large eddy current is generated in the opposite direction of the heated material, and the resistance of the heated material generates Joule heat, so that the temperature of the material itself rises rapidly, which is the principle of induction heating.

  Second, high frequency induction heating machine is widely used


  High-frequency heating machine can be used for rapid heating of all metals, such as: iron, steel, cast iron, stainless steel, copper, aluminum, tin, gold, silver, etc.


  1, hot forging and pressing industry --- whole forging, partial forging, drill pressing.


  2、Welding---A variety of metal products brazing, tool blade welding, copper pipe welding (in the fiber optic cable manufacturing industry can be used for steel strip lap welding).


  3, heat treatment --- metal quenching, annealing, tempering; especially local treatment (in the fiber optic cable manufacturing industry can be used for sheathing material and metal strip stripping).


  4, melting --- casting melting, precious metal melting, laboratory small melting.


  5, other applications --- powder coating, metal implant plastic, heating and de-oiling (in the fiber optic cable manufacturing industry can be used for steel wire extrusion pad layer steel wire de-oiling, impurities).
