Frequently Asked Questions
How exactly does induction heating work? Induction heating machine is mainly using the magnetic field principle to heat the workpiece, the induction heating system is mainly an induction coil, power supply and metal parts that need to be heated.
Induction heating power is converted from AC power to higher frequency AC power, which is transmitted to the induction coil to generate electromagnetic fields in the coil.
Because the metal workpiece that needs to be heated is also a conductor, the coils create loops of magnetic lines that pass directly through the metal workpiece placed in the coil, form a closed current loop,and metal has less resistance,also with a higher current.When these high-current magnetic induction heating lines pass through the metal workpiece, this makes the electrons inside the metal very active, bumping into each other and rubbing against each other to generate heat, which makes the metal itself very hot.
Induction heating machine is widely used in industrial manufacturing, such as induction hardening, induction melting, induction welding, induction forging, and so on.
- Induction welding: Cutting, drilling tools, cutting tools, woodworking tools, lathe tool, drill bit, brazing, reamer, milling cutter, drill bit, saw blade serrate, glasses frame, steel pipe, copper pipe welding, cutting teeth, the same of dissimilar metal welding, compressor, pressure gauge, stainless steel pot, relay contact composite materials with different welding, welding transformer winding copper wire, storage (gas filling and the mouth of the welding, Welding of stainless steel table and kitchenware).
- Induction heat treatment: Gear, machine tool guide rail, hardware tools, pneumatic tools, power tools, hydraulic parts, ductile iron, auto parts, internal parts, and other mechanical metal parts (surface, inner hole, local, integral) induction quenching, induction annealing, stainless steel pot products stretching.

For round steel bar with diameter below 100mm, induction heating annealing of metal material for drawing, molding, embossing, bending, smashing head, steel wire (iron wire) heating nail, stainless steel products annealing, drawing, expansion, thermal expansion, etc.
- Induction melting: Our company has an induction melting furnace, and a vacuum induction melting furnace, and is widely used in all kinds of metal products, steel, stainless steel, brass, copper, aluminum, aluminum alloy, gold, silver and other metal materials smelting, smelting capacity from 3kg-10000kg. There are three types of melting furnaces: dump type, top out the type, and fixed type induction melting furnace.

What is the efficiency of induction heating? Which frequencies are best for your application? The following guide will give you some introduction to the efficiency of induction heating. For more information, please contact ZHENGZHOU KETCHAN technical staff.
Induction heating machine, induction heating power supply selection generally need the following parameters:
- The shape of the workpiece being heated, the outer dimensions, and the weight of the workpiece is heated.
- The material composition of the workpiece to be heated (general induction heating, only for metallic conductors and non-metallic conductors such as graphite).
- The time required for the heating of the workpiece to be heated, and the target temperature.
- The heating efficiency requests.
Once the above data are confirmed, we can choose the related induction heating machine power and related induction heat treatment systems.
We are considering that what we provide you can give you all the benefits in your productions. For this, we are developing unique induction heating treatment solutions for you together.
Because of the multi advantages of the induction heating technology. Now more and more factories are choosing induction heating as the main heat treatment source.
- Induction heating does not need to heat the workpiece as a whole, but can selectively heat the partial workpiece, so as to achieve less power consumption purpose, and the workpiece deformation is not obvious.
- Fast induction heating speed, which can make the workpiece reach the required temperature in a very short time, even within 1 second. So that the workpiece surface oxidation and decarbonization are relatively slight, most of the workpieces do not need gas protection.
- The surface hardened layer can be regulated by adjusting the operating frequency and power of the induction heating equipment as required. Therefore, the martensite structure of the hardened layer is fine, and hardness, strength, and toughness are relatively high.
- The workpiece after the induction heating treatment, there is a thick ductile area under the hard surface layer, with better compression internal stress, making the workpiece fatigue resistance and braking ability higher.
- Induction heating equipment is easy to install on the production line, easy to realize mechanization and automation, easy to manage, can effectively reduce transportation, save manpower, and improve production efficiency.
- One induction heating system can realize multi-purpose. Not only can complete induction quenching, induction annealing, induction tempering, induction normalizing, induction tempering, and other induction heat treatment processes but also can complete induction welding, induction melting, induction thermal assembly, induction thermal disassembly induction diathermy forming, and other work.
- Easy to use, easy to operate, and can be started or stopped at any time. And without preheating.
- Not only can do the manual operation, semi-automatic but also automatic operation; It can work continuously for a long time, or stop used randomly. It is conducive to the use of equipment in the preferential period of power supply through price.
- High power utilization rate, environmental protection, and energy saving, safe and reliability, good working conditions for workers, national advocates, and so on.
