    product description


    Super audio induction heating furnace

    I. Overview: Super Audio most industrial induction heating furnace for surface hardening metal parts, a certain surface of the workpiece is induced current, rapid heating of the part surface, then the heat treatment method of a metal is rapidly quenched. Super-audio induction heating equipment, which is a device that inductively heats a workpiece to perform surface hardening.

    Ultra-frequency  induction heating furnace principle: the workpiece into the sensor, the sensor is typically an input intermediate frequency or high frequency alternating current (1000-300000Hz or more) hollow copper tube. The alternating magnetic field generates an induced current of the same frequency in the workpiece. The induced current is uneven in the distribution of the workpiece, strong on the surface, and weak inside, to the core close to 0 , using this skin effect , can rapidly added to the surface heat , the surface temperature rises within a few seconds deg.] C to 800-1000, and the core portion temperature rise is small.

    , heating forging of bars within 800mm in diameter ;

    , mechanical parts, hardware tools, straight shank twist drill hot, hot rolling

    V. Application hardening furnace in terms of ultra-audio frequency induction heating

    1. Quenching of various gears, sprockets and shafts;

    , various semi-axles, leaf springs, forks, valves, rocker arms, ball-pins and other automotive and motorcycle parts quenching.

    3. Quenching of various internal combustion engine parts and speed reducer parts;

    4. Quenching treatment of machine tool bed rails in the machine tool industry (lathes, milling machines, planers, punching machines, etc.).

    , quenching of various hand tools such as pliers, knife and scissors, axe, hammer, etc.

    Sixth, application of super audio frequency induction heating furnace in welding of

    1. Welding of various diamond composite drill bits;

    2. Welding of various carbide heads and saw blades;

    3. Welding of mining parts such as various picks, drill heads, drill pipes, coal drill bits and wind drill bits;

    Seven applications in ultra-audio frequency induction heating furnace annealing terms

    , a variety of super audio induction heating equipment or local annealing

    , various stainless steel products annealing treatment

    , metal material heating annealing, rising type

    Eight, what are the advantages of super audio induction heating furnace ?

    1. Adopt international famous company Siemens IGBT power device and unique inverter technology, designed with 100% load continuation rate, 24 hours operation under maximum power , high reliability guarantee.

    , the self-control type can adjust the heating time, heating power, holding time, holding power and cooling time; greatly improve the quality of heating products and the repeatability of heating, simplifying the operation technology of workers.

    , light weight, small size, simple installation, connected to 380V three-phase power, water, water, can be completed in a few minutes.

    , the footprint is very small, easy to operate, can be learned in a few minutes.

    , especially safe, the output voltage is lower than 36V , eliminating the danger of high voltage electric shock.

    , the heating efficiency is up to 90% , the energy consumption is only 20% - 30% of the high frequency of the old-fashioned tube , almost no electricity in the standby state, and can work continuously for 24 hours.

    7. The sensor can be disassembled and replaced freely, and the ultra-fast heating greatly reduces the oxidative deformation of the workpiece.

    8. The latest environmentally friendly products that replace the heating of dangerous substances such as oxygen, acetylene and coal, are safer and safer to produce without open flame.

    9. The equipment has over-current, over-voltage, over-temperature, water shortage, and lack of perfect automatic protection functions, and is equipped with a fault self-diagnosis alarm system.

    10 , the device has a constant current and constant power control function, greatly optimize the metal heating process, achieve efficient, rapid heating, the product's superior performance is fully exerted.

    Nine, what should you pay attention to when selecting a super-audio heating furnace ?

    1, heating, welding-based ultra-frequency induction heating furnace, a frequency of about 15kHz, about φ80 heatable work, various carbide cutting tools and the like may be welded

    , quenching super-audio induction heating equipment , the frequency is about 40KHZ , the small one can quench φ10 or so high-precision small shaft, the hardened layer is kept within 1mm , the larger one can be φ250 diameter large shaft, and can also quench φ500 or so gear.

    3, based super audio induction heating annealing apparatus may be integral with or part of the annealing process various mechanical parts. The φ300 diameter stainless steel container can be subjected to tensile annealing.

    Ten, what are the misunderstandings when choosing a super audio heating furnace ?

    Misunderstanding 1: only look at power, do not look at frequency

    When standard parts, fasteners, etc. heating, when heating the workpiece diameter "is 80mm, IF equipment should be selected, while still resulting in a high frequency outside the workpiece opportunity" burn flow "inside the" black "(commonly known as" burn-impermeable " ), not only the equipment efficiency is greatly reduced, but also reduce the mold life or even cause mold damage, invisible cost increase, but I do not know the reason.

    Misunderstanding 2: just look at the output, do not look at the input

    Ignore the efficiency of the equipment and the power consumption factor. After purchasing the equipment, I found out that it was an " electric tiger " , which made it affordable and could not afford the embarrassing situation. For example, the same 80 machine, but an input power is 80kw , but the equipment work efficiency is very different, although the heating requirements can be completed, but the power consumption makes Yonghe complain not to fall. The output power of the device outputting 80lw is as high as 120kVA .

    Misunderstanding 3: only look at the model, do not look at the power

    For example, the equipment input current 120A and input power 120KVA are mixed together, collectively referred to as 120 machines, so that after the purchase, the real power is only 80KVA , which is obviously cheap, but it is a loss.
