Aluminum melting furnace

 The main components of the aluminum melting furnace are:

(1) TXZ-15～TXZ-160 intermediate frequency power supply (2) Compensation capacitor box (3) Tipping type melting furnace/fixed melting furnace 2. Oscillation frequency: 2-20KHZ 3. Suitable for smelting from 3KG to 300KG

Smelting principle of the intermediate frequency smelting furnace: The power supply adopts all-solid-state Siemens IGBT frequency conversion module technology, and adopts the principle of magnetic field induction eddy current heating. It uses current to pass through the coil to generate a magnetic field, and heats the metal through the electromagnetic eddy current induction generated by the metal itself. The metal is instantly heated through the crucible container. It begins to melt, melting the metal into liquid, and then carries out processes such as smelting, refining, purifying, and then casting and pouring molding using various molds.

The equipment structure of the intermediate frequency melting furnace:

1    The most basic unit in the intermediate frequency power supply and capacitor box and smelting furnace.According to different application requirements, it may also include infrared thermometers, temperature controllers and other devices; the melting furnace is divided into three types: tip-over melting furnace, ejection melting furnace and fixed melting furnace.Tip-over smelting furnaces can be divided into hand-operated mechanical tip-over furnaces, electric tip-over furnaces and hydraulic tip-over furnaces according to the tip-over method.   2   Normally, a coaxial cable is used to connect the intermediate frequency power supply and the capacitor box, and a water-cooled cable is used to connect the capacitor box and the smelting furnace.

Equipment characteristics:

1. All-solid-state IGBT frequency conversion and function adjustment, soft-switching resonance dual control and frequency automatic tracking technology are a guarantee of high reliability;

2. Ultra-small size, saving 10 times of production space for customers;

3. High efficiency and energy saving, extremely high power factor and power efficiency within the full power range;

4. Broadband 1~20KHZ frequency automatic tracking adaptability, no need for on-site debugging;

5. Full load, 24-hour continuous working capability;

6. Constant output voltage/constant output power control selection function;

7. Full display of frequency, power, voltage and current.

Features of medium frequency melting furnace:

 (1) Medium frequency melting furnace is used for melting and heating of steel, stainless steel, copper, aluminum, gold, silver and other metal materials; the melting capacity ranges from 3KG to 300KG.

 (2)   Medium frequency melting has a good electromagnetic stirring effect, which is beneficial to the uniform temperature and structure of the melted metal, is beneficial to dross, and reduces impurities;

 (3)   The frequency range is wide, from 1KHZ to 20KHZ. The induction coil and matching compensation capacitor can be designed comprehensively considering the melting volume, electromagnetic stirring effect, heating efficiency, noise during operation and other factors to determine the output frequency;

 (4)   Compared with silicon controlled medium frequency, it saves at least 20% more energy;

 (5)   The equipment is small in size and light in weight, and its melting capacity ranges from a few kilograms to hundreds of kilograms. It has a wide range of options and is suitable for both factory production and small-volume smelting in schools and research institutes.

Main smelting furnace specifications and heating capacity:

The maximum heating capacity of each melting furnace is listed in the following table. When the furnace is cold, the melting time per furnace is 50--60 minutes. When the furnace is hot, the melting time per furnace is 20--30 minutes.
