Induction heating technology application in China are widely cognitive

Induction heating technology application in China are widely cognitive

Along with the development of the technology (semiconductor, transistor), now the equipment size and weight, compared to the previous model can reduce nearly 10%. With compact structure, light weight, and flexibility of equipment application and the advantage of price, the purpose of the induction heating are extensive.
By induction heating workpiece must be electrical conductor, such as metal or silicon semiconductor. Through the induction coil, the high frequency energy is transmitted to the workpiece. Induction coil or simple geometry and requirements of sensor and the workpiece contour matching, in most cases, the induction coil is made of copper, bending forming and using water cooling.
We will try to show you some general some within the scope of application, at the same time, help you according to your actual demand make some proposals on how to use induction heating. Practical application is very extensive, but is not the same, but with the development of induction heating technology, many of the current process can be through the use of induction heating technology and improved!

Vacuum furnace development history

Vacuum furnace development history 

 Structure, the heating process, temperature control and furnace atmosphere, such as vacuum furnace, will directly affect the quality of products after processing. In the forging furnace, improve the heating temperature of the metal, can reduce the deformation resistance, but the temperature is too high will cause grain growth, oxidation or burnt, seriously affecting the quality of the workpiece. During the heat treatment, if the steel is heated to a point above the critical temperature, and then suddenly cooled, can improve the hardness and strength of steel; if heated to a point below the critical temperature after slow cooling, the hardness of the steel but also make leaving lower toughness increased.
In order to obtain accurate dimensions and surface finish of the workpiece, or to reduce the metal oxide in order to protect the mold, reducing the allowance purposes, you can use a variety of small non-oxidation furnace. Less in the open flame no oxidation furnace, use of incomplete combustion of the fuel reducing gas, in which the heating of the workpiece can be reduced to 0.3% or less oxidation loss rate.
Vacuum furnace is controlled using the atmosphere artificially prepared, can be introduced into the furnace gas carburizing, carbonitriding, bright quenching, normalizing, annealing heat treatment: in order to change the microstructure, the purpose of improving the mechanical properties of the workpiece. The particles in the flow furnace, the combustion of the gaseous fuel, or other fluidizing agents externally applied force flowing hearth graphite particles or other inert particle layer, buried in the workpiece can be achieved in the particle layer reinforced heating, can also be infiltration carbon, nitrogen, and other non-oxidizing heating. In a salt bath furnace, a molten salt solution as a heating medium, prevent oxidation of the workpiece and decarbonization.
With the development of technology, we now have a variety of highly efficient vacuum furnace,such as heat treatment vacuumfurnace,Sintering vacuum furnace,Carburizing vacuum furnace,Nitriding vacuum furnace,Gas quenching vacuum furnace,Induction vacuum furnace,Soldering vacuumm furnace,Vacuum induction melting furnace,Lab vacuum furnace,Vacuum melting furnace,Special purpose vacuum furnace.

Generation of Electron Beam Melting

                                Generation of Electron Beam Melting

Electronic speed continuous melting (EBCHM or EBCHR)
EBCHR (under high vacuum) allows the vacuum melting furnace, refining and solidification of the final ingot separated, preventing the molten metal flows into the ingot while insoluble components, which provides sufficient residence time to separate the volatile and the reaction of melting rate, and it can be achieved that the residue was evaporated to an impurity element is not required to detect almost undetectable level. Cr volatilization problems exist, the charge must be replenished in the. it's reported in the literature, the content of oxygen and nitrogen in the alloy is significantly reduced, non-metallic inclusions through the water-cooled liquid separator is mechanically removed or decomposed at the heat treatment intense electron beams, so the cleanliness of the material is better than other methods of melting the alloy.
Electron beam melting slag film (EBFFM) is a certain percentage of the slag film on the metal surface cooling bed, non-conducive to slag film covering part of the degassing of molten metal and slag film covering part helps reduce evaporation losses, complete removal of impurities task. Less work reported in this area.
