Application of 2.5MM - 4.0MM Cast Iron Electrode in Optical Fiber Manufacturing
Joule heat - the self-heating of the electrolyte filled in the capillary in the high electric field.
2.5MM-4.0MM cast iron electrode - full name "2.5MM-4.0MM cast iron electrode", also known as high frequency induction heating equipment, high frequency induction heating device, high frequency heating power, high frequency power supply, high frequency welding machine, high frequency induction Heating machine, high frequency induction heater (welding), etc., it is mainly on the metal induction heating (non-contact); can be very fast heating of metal, power, small size, easy installation, easy to operate , Safe and reliable, fast heating speed, the advantages of a wide range of applications.
With the rapid development of Internet business, 3G (3rdGeneration third generation mobile communication technology) and multimedia applications, the network traffic is expanding exponentially, which requires the network to have high bit rate data transmission capacity and large Throughput cross capability. After the emergence of optical fiber communication technology, its nearly 30THz huge potential bandwidth capacity to the communications field has brought the opportunity to flourish, especially in the information highway since the light technology began to penetrate the entire communication network, optical fiber to the all-optical network Advancing trend. Optical fiber communication in China has gone through more than 20 years of history. Market is the lifeblood of the industry, the price is the lifeblood of enterprises, how to reasonably reduce product costs, improve product quality, to ensure that users use requirements, is the top priority of the enterprise. This paper focuses on the traditional fiber optic cable gluing method and the new process - high frequency induction heating comparison.
First, the principle of brief
It is well known that the water seepage performance of the cable is an environmental performance standard which is strictly required by each user, and the ladle structure cable is easy to seep in the strip lap, the traditional way is usually hot melt glue filling, so that the strip lap joints to prevent water seepage The But 2.5MM-4.0MM cast iron electrode in the traditional way there are many shortcomings, such as the amount of glue will cause seepage occurs, plus too much glue will cause the jacket when the package occurs, so it is difficult to control the amount of glue; But also because the surface of the steel film is not firmly bonded to the core of the accumulation of foam caused by the phenomenon of sheath out of the package. The new process uses the principle of high frequency induction heating to melt the steel strip surface, not only to make the strip lap firmly bonded, but also improve the bond between the strip and the sheath strength, completely solve the problem of water seepage and sheath Out of the bag phenomenon.
High-frequency induction heating principle is the dielectric material in the high-frequency electric field under the action of molecular polarization phenomenon, and according to the direction of the electric field, because the high-frequency electric field to change the direction of the molecular speed, the dielectric material will be due to dielectric loss fever. The high frequency current flows to a heating coil (usually made of copper) that is wound into a ring or other shape. The magnetic flux will be through the entire heated material, in the 2.5MM-4.0MM cast iron electrode heated material inside the opposite with the heating current. In this way, the magnetic material will be heated in the coil. Of the direction of a large eddy current, due to the resistance of the heated material generated Joule heat, so that the material itself, the rapid rise in temperature, which is the principle of induction heating.
Second, 2.5MM-4.0MM cast iron electrode widely used
2.5MM-4.0MM cast iron electrode can be all the metal for rapid heating, such as: iron, steel, cast iron, stainless steel, copper, aluminum, tin, gold, silver and so on.
1, hot forging industry - the whole forging, local forging, bit to suppress.
2, welding --- all kinds of metal products brazing, tool blade welding, copper welding (in the cable manufacturing industry can be used for lap welding).
3, heat treatment --- metal quenching, annealing, tempering; especially local treatment (in the cable manufacturing industry can be used for sheathing and metal strip stripping).
4, smelting --- casting smelting, precious metal smelting, laboratory small smelting.
5, other applications --- powder coating, metal implantation of plastic, heating to the oil (in the cable manufacturing industry can be used for steel wire pad layer of steel to oil, impurities).
Third, the application of traditional hot melt machine and high frequency welding comparison
