Application

For Gear, shaft, Pipe, Bearing, Pump fitting, steel plate, roller etc. hardening

A. Heating (hot forging, hot fitting and smelting):

1 The aim of hot forging is to forge workpieces of a certain temperature (different materials require

different temperatures) into other shapes with the help of a press, forging machine or other equipment,

as for example, hot extruded watch cases, watch flanges, handles, mold fittings, kitchenware and cutlery,

works of art, standard parts, fasteners, manufactured mechanical parts, brass locks, rivets, steel pins

and pins.

2. Smelting is basically the use of high temperature to dissolve metals into liquid, mainly applies to the

smelting of iron, steel, copper, aluminum, zinc and other various precious metals

3.Electric resistance heating is 100% energy efficient in the sense that all the incoming electric energy is converted to heat. However, most electricity is produced from coal, gas, or oil generators that convert only about 30% of the fuel's energy into electricity. Because of electricity generation and losses, electric heat is often more expensive than heat produced in homes or businesses.

B. Heat Treatment (surface quench):

It is mainly aims to change the rigidity of the metal materials through the heat treatment to work pieces. Detail

applications are stated as follows:

1. heat treatment of gear and shaft 2. brazing of diamond tools 3. brazing of electrical kettle bottom 4. tube heating for coating 5. heating of stainless steel vessel for annealing.

It mainly aims to melt the solder by heating it to a certain temperature for the purpose of connecting two types of

metals of the same material or different materials.

1. Welding of various hardware cutting tools, such as diamond tool, abrasive tool, drilling tool, alloy saw blade,

hard alloy cutter, milling cutter, reamer, planning tool and solid center bit.
2. Welding of various hardware mechanical gadget: Silver soldering and brazing of metals of the same variety or

different varieties, such as hardware toilet and kitchen products, refrigerating copper fitting, lamp decoration

fitting, precision mold fitting, hardware handle.
3. Compound pot bottom welding is mainly applicable to the braze welding of circular, square as well as other

irregular plain pot bottom.

D. Annealing (tempering and modulation):

1. Annealing of various stainless steel products, such as stainless steel basin, annealed and extruded can, annealed

folded edge,annealed sink, stainless steel tube, tableware and cup.
2. Annealing of various other metal work pieces, such as golf ball head, cue, brass lock, hardware copper fitting, kitchen

knife handle, blade, aluminum pan.

Operating Principle

Frequency conversion electromagnetic induction heating or induction heating for short is a method for heating metal

materials by converting power frequency power supply into that of specific range based on the principle of electromagnetic

induction. This type of heating technique is also applicable to packing industry (such as sealing of aluminum foil used in medicine and food industry), semiconductor material . Basic components of induction heating system include induction coil, AC power source and work pieces. Induction coil can be fabricated into different shapes as per different heated objects. The coil is connected with the power source providing

alternating current for coil.

Advantages of Induction Heating Equipment

1. Fast heating: the minimum rate of heating is less than 1 second (rate of heating is available for adjustment and control).

2. Wide coverage of heating: it can be used to heat various metal parts (replace removable induction coil as per different

perating switches).

3. Easy installation: it can be used once it is connected with power source, induction coil as well as water supply pipe and

rising pipe; it is small in size and light in weight.

4. Easy operation: you can learn to operate it within several minutes.

5. Fast start-up: it can be started to perform heating operation on condition that water and power supply is available.

6. Low power consumption: As compared with conventional vacuum tube high frequency equipments, it can save the power

by approximately 70%. The smaller the size of the work piece is, the lower power consumption

would be.

7. High effectiveness: it has such features as uniform heating (it is applicable to adjust the spacing of the induction coil to

ensure the appropriate temperature as required by each part of work piece), fast warming and limited

oxic horizon, and can guard against any waste after annealing.

8. Comprehensive protection: it has such functions as overpressure, over-current, overheat and water shortage alarm indications

as well as automatic control and protection.

9. Controllable temperature: it is applicable to control the temperature for heating work pieces as per the preset heating time,

and thereby control the heating temperature at a certain technical point.

10. Comprehensive full load design: it can work continuously for 24 hours.

11. Small size and light weight: it has a weight of only several dozens of kilograms, of which, the limited floor space can effectively

save the workshop space.

12. Elimination of high voltage: it requires no step-up transformer which may produce approximately ten thousand voltage, and

thus can ensure the maximum safety.
