Silver furnace

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

 Smelting principle: 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 and begins to melt. The metal is melted into liquid, and then smelted, refined, purified, and then cast and molded using various molds. Compared with coke furnaces, gas furnaces, oil furnaces, and ordinary resistance furnaces, the melting speed is faster, low energy consumption, environmental protection, and volume Small operations are simple.

Features of medium frequency melting furnace:

 (1)  Medium frequency melting furnace is used for melting steel, stainless steel, copper, aluminum, gold, silver and other materials.

 (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 application:

Intermediate frequency power supplies are mostly used in heating situations that require heat penetration, such as:

(1) Heating and forging of standard parts

(2) Smelting of various metal materials

(3) Motor rotor heating coordination

(4) Heating and expansion of steel pipe ends

(5) Mold penetration

Structure 1: intermediate frequency power supply + compensation capacitor box + intermediate frequency induction coil

This structure is the most commonly used, such as medium frequency forging furnace,Medium frequency melting furnaceAll adopt this structure, the equipment is simple, the loss is low, the work efficiency is high, and the manufacturing cost is low.

In this structure, the induction coil is relatively long and is usually wound with a 3-10 meter long copper tube.Since the intermediate frequency power supply is directly output, the voltage on the induction coil is higher, and it is not isolated from the main power, so the induction coil must be well insulated and cannot be directly exposed;

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.
