What is the principle of high frequency induction heating equipment?

2023-02-27

What is the principle of high frequency induction heating equipment? High-frequency induction heating equipment refers to the surface quenching equipment of the workpiece, which belongs to the metal heat treatment method, so what is the principle of high-frequency induction heating equipment? What are the application areas? The workpiece is placed in the inductor. The induction heating equipment is generally a hollow copper tube. The medium frequency or high frequency alternating current (1000-300000Hz or higher) is applied. The alternating magnetic field generates an induced current of the same frequency in the workpiece. The induced current is unevenly distributed in the workpiece, with strong surface, weak inside and close to zero center. By using this skin effect, the surface of the workpiece can be rapidly heated and the surface temperature will rise to 800-1000 in a few seconds, and the temperature in the center rises very little. Scope of application: 1. Welding of carbide saw blade teeth. 2. Welding and annealing of spectacle frames and parts. 3. Thin wires of jewelry heads, thin parts of various electronic components, welding and silver welding). 5. Mechanical and electrical industry (fine metal joints silver copper welding micro-motor shaft and other quenching and tempering). 6. Wire industry (fine wire strip annealing). 7. Tool welding, paper cutter, shoe blade quenching. 8. Toy industry (thin coiled metal sheet tempering). How to choose medium frequency induction heating equipment

Tempering method of induction heating equipment

2023-02-17

The tempering method of induction heating equipment The induction heating quenching temperature (part surface temperature) is higher than the general quenching temperature because the induction heating speed is fast and the superheat is large, which makes the critical point of the metal rise quickly. The purpose is to reduce the quenching stress. In order to avoid quenching cracks, sometimes tempering is also to reduce the hardness to meet the technical requirements of parts. Tempering generally includes furnace tempering, induction tempering and self-tempering. 1. induction tempering Induction heating tempering requires the surface temperature, surface hardness, power, heating time and hardness gradient of the hardened layer of the induction heating equipment. 1. Disadvantages of traditional tempering and heating: long hours, reason: the external heating body is heated by heat conduction and radiation, so there is enough time for heat to be conducted to the inside of the steel, and the temperature is uniform. 2. The advantages of modern induction heating induction heating equipment: short time, reason: and the traditional tempering heating method is essentially different, that is, induction heating is the use of induction eddy current to self-heat the steel surface. 1. Use another set of suitable low-frequency power supply and inductor for tempering, and now this method is widely used. Secondly, the use of the original quenching heating power supply, in the original sensor equipment, by reducing

Application of Induction Heating Equipment in Optical Cable Manufacturing

2023-02-07

Analysis of the Application of Induction Heating Equipment in Optical Cable Manufacturing It is well known that the water permeability of optical cable is an environmental protection performance index strictly required by many users. However, the optical cable with ladle structure is easy to seep water where the steel belts overlap. The traditional way is that we usually fill it with hot melt adhesive to completely bond the overlapping parts of the steel belts to prevent water seeping. However, the traditional method has many disadvantages, such as water seeping due to insufficient glue, if the amount of glue is too large, there will be a bag when the sheath is extruded, so it is difficult to control the amount of glue artificially. In addition, the induction heating equipment will cause the sheath to fall off, because the polyester film on the surface of the steel belt is not firmly bonded and accumulates in the mold core. The new process uses the principle of high-frequency induction heating to melt the film on the surface of the steel belt, which not only makes the steel belt joint firm, but also improves the bonding strength of the sheath and steel belt, the problems of water seepage and sheath out of package are solved. The principle of high-frequency induction heating is: the molecular phenomenon of dielectric materials occurs under the action of high-frequency electric field, and they are arranged according to the direction of the electric field. Because the high-frequency electric field changes the molecular direction at a relatively fast speed, the dielectric material will generate heat due to dielectric loss, and the high-frequency current flows to the heating coil (usually made of copper tube) wound into a ring or other shapes. In this way, a strong magnetic beam with instantaneous change is generated in the coil,
