What aspects of performance should be paid attention to when purchasing intermediate frequency furna

Generally it is necessary to pay attention to whether the power can meet the requirements of the heating workpiece, as well as some aspects of ease of operation, in fact, the operation of different brands on the market is almost the same, I personally think that the most important focus is on the after-sales service of the manufacturer, usually ask this kind of question, indicating that you do not know this equipment very well, so the manufacturer's after-sales service is very important, if the manufacturer only sells regardless of after-sales, you buy it is equivalent to buying it in vain. My friend bought Suzhou Hongchuang equipment (Suzhou Hongchuang high-frequency heating equipment****), which should give you a reference! I hope you can !!

Thank you!!!

Also pay attention to the water system.

Open cooling tower + pool, this conventional way, the amount of water evaporation is large, resulting in an increase in the content of scale components, resulting in the scaling of various equipment on the system, if the thickness of the scaling on the inner wall of the pipeline, the inside of the equipment, and the inside of the electrical components increases to a certain extent, it seriously affects the heat dissipation, and the heat emitted by the electrical components when working cannot be taken away in time, and the temperature rises, and the components, such as thyristors, etc., produce production failures and affect production.

Closed cooling tower, completely closed circulation, softened water medium, low scale content itself, due to isolation from the outside world, no evaporation, no consumption, no impurities entering, low circulation temperature, never scale, once and for all. Handan Bingfeng specializes in the production of closed cooling towers for induction furnaces, which are small in size, high in automation, simple in operation, and can be installed both indoors and outdoors.

Medium frequency induction heating: It is a power supply device that converts the power frequency 50Hz alternating current into medium frequency (above 300Hz to 20k Hz), converts the three-phase power frequency alternating current into direct current after rectification, and then turns the direct current into adjustable intermediate frequency current, supplies the intermediate frequency alternating current flowing through the capacitor and induction coil, generates high-density magnetic field lines in the induction coil, and cuts the metal material contained in the induction coil, and produces a large eddy current in the metal material. This eddy current also has some of the properties of an intermediate frequency current, i.e., the flow of free electrons in a resistive metal body generates heat.

For example, if a metal cylinder is placed in an induction coil with alternating intermediate frequency current, the metal cylinder is not in direct contact with the induction coil, and the temperature of the energized coil itself is very low, but the surface of the cylinder is heated to redness, or even melting, and the speed of redness and melting can be achieved as long as the frequency and the strength of the current are adjusted. If the cylinder is placed in the center of the circle, then the temperature around the cylinder is the same, and the heating and melting of the cylinder does not produce harmful gases and strong light to pollute the environment. Advantages of medium frequency induction heating:

Fast heating speed, less oxidation and decarbonization Because the principle of medium frequency induction heating is electromagnetic induction, the heat is generated in the workpiece, because the heating method heats up quickly, so the oxidation is very small, the heating efficiency is high, and the process repeatability is good. Uniform heating, high temperature control accuracy Induction heating is easy to achieve uniform heating, and the temperature difference between the core surface is small. The application of a temperature control system allows for precise control of the temperature.

Low energy consumption, no pollution Compared with other heating methods, induction heating has high heating efficiency, low energy consumption and no pollution; All indicators can meet the requirements of users. Under diathermic conditions, the power consumption from room temperature to 1100 is less than 360

Medium frequency induction heating: Medium frequency induction heating power supply is mostly used in many fields such as surface quenching of industrial metal parts, metal melting, bar diathermy, etc., which is to make the surface of the workpiece produce a certain induction current, quickly heat the surface of the part, and achieve the effect of rapid heating of the surface, and even diathermy melting. Medium frequency induction heating has been widely used in smelting, casting, pipe bending, hot forging, welding and surface heat treatment industries due to its advantages of high heating efficiency, fast speed, good controllability, easy mechanization and automation.

High-frequency induction heating: Heating is carried out by using the induced current (eddy current loss) generated by the conductor under the action of a high-frequency magnetic field, as well as the hysteresis loss caused by the magnetic field in the conductor. High-frequency induction heating heat treatment of metal hardware and tools, brazing, welding, welding, welding of steel pipes and copper pipes, quenching of mechanical parts and automobile and motorcycle parts, annealing and demagnetization of stainless steel, red-hot diathermy before forging of bars, pushing elbow stretching and some special heating, and melting and smelting of small amounts of alloys.

According to the different workpieces, the workpiece can be heated locally, the inner hole, or the whole heating, surface heat treatment or overall heat permeability, the maximum temperature can reach 1500-2500.

(1) High melting efficiency, good power-saving effect, compact structure and strong overload capacity (2) Low temperature around the furnace, less smoke and dust, and good working environment.

3) The operation process is simple and the melting operation is reliable.

4) The metal composition is uniform.

5) Fast melting and heating, easy control of furnace temperature, high production efficiency.

6) The furnace has a high utilization rate and is convenient to replace the variety.

The high-frequency induction heating furnace uses a high-frequency power supply to establish a high-frequency magnetic field, so that the ferromagnetic material generates induced eddy currents and heats up to achieve the purpose of heating the material. High-frequency induction heating furnace is adopted.

200-2500Hz high-frequency power supply for induction heating, smelting and heat preservation, high slope electric furnace is mainly used for smelting carbon steel, alloy steel, special steel, can also be used for copper, aluminum and other non-ferrous metals smelting and temperature raising. The equipment is small in size, light in weight, high in efficiency, low in power consumption, fast in melting and heating, easy to control in furnace temperature, high in production efficiency, ultra-small in size, light in weight, movable, and covers an area of less than 1 square meter, saving 10 times of production space for customers.

1. Welding (brazing, silver shouting, brazing).

All kinds of hardware tool welding.

Welding of various hardware and mechanical parts.

Composite pot bottom welding.

Electric kettle heating plate welding.

2. Heating (hot forging, hot fitting, melting).

Hot forging is mainly to heat the Duanye workpiece to a certain extent (depending on the material, the temperature is also different) through punching, forging or other forms to press him into other shapes.

Thermal fit mainly refers to the heating of metals between different metals or between metals and non-metals, and the use of the principle of thermal expansion or thermal melting to link together.

Smelting refers to the high temperature of the metal to be melted into a liquid.

3. Heat treatment (surface quenching).

It is a change in the hardness of the metal material after heating or other treatment of the workpiece.

4. Annealing. Annealing of various stainless steel industries.

Annealing of various other metal workpieces.

Roughly understand the following: brazing, brazing, melting, surface quenching, tempering, quenching and tempering.

There are a lot of hardware things, I heard a friend say it.

1. Before opening the furnace, check whether the electrical equipment, water cooling system, inductor copper pipe, etc. are in good condition, otherwise it is forbidden to open the furnace.

2. The furnace melt damage should be repaired in time if it exceeds the regulations. It is strictly forbidden to melt in a crucible that is too deeply damaged.

3. There should be a special person responsible for power transmission and furnace opening, and it is strictly forbidden to contact the sensor and cable after power transmission. Those on duty are not allowed to leave their posts without authorization, and they should pay attention to the external conditions of the sensors and crucibles.

4. When loading, it should be checked whether there are flammable and explosive harmful substances mixed in the charge, if there is any, it should be removed in time, it is strictly forbidden to add cold materials and wet materials directly into the molten steel, and it is strictly forbidden to add large pieces of material after the molten liquid is filled to the upper part to prevent the lid.

5. It is strictly forbidden to mix iron filings and iron oxide when repairing the furnace and pounding the crucible, and the crucible must be dense.

6. The pouring site and the pit in front of the furnace should be free of obstacles and no stagnant water to prevent the molten steel from falling to the ground.

7. The molten steel is not allowed to be overfilled, when the hand bag is poured, the two should cooperate consistently, walk smoothly, and do not stop in a hurry.

8. The medium frequency generator room should be kept clean, and it is strictly forbidden to bring flammable and explosive materials and other sundries into the room, and smoking is prohibited indoors.

Using the principle of electromagnetic induction, eddy currents are generated in the workpiece placed in the induction coil, so that the workpiece is heated and heated to the required temperature. The device uses series resonance or parallel resonance, so the power factor is high. Compared with the traditional heating method, it has the advantages of high efficiency and low pollution.

The equipment has a wide range of applications in industries such as forging and metal heat treatment.
