DESCRIPTION

VLF Vacuum Suspension Melting Furnace


 

       Vacuum induction levitation melting furnace(0.3-2KG) is to split water cooled copper crucible put in a strong alternating magnetic field, using induction eddy current heating the water cooled copper crucible metal melting, rely on electromagnetic force makes the molten metal does not have close contact with water cooled copper crucible.

This prevents the crucible from polluting the materials needed for smelting, and thus can smelt high purity metal materials.

The liquid alloy in the water-cooled copper crucible can also be injected into the ingot mold by rotating the molten metal.

The vacuum suspension melting furnace is suitable for the smelting of active metals such as titanium zirconium and rare earth materials, and the smelting and precision casting of titanium alloys.

It is mainly used in the production of high purity metal materials, semiconductor monocrystalline materials, high melting point alloys and 3D printing.

 

I. Features of the equipment

1. Using the horizontal furnace, the side door is open, the material is convenient, the furnace is compact, and the space is small

2. The temperature control temperature can be controlled by 30 paragraphs. The temperature and temperature can be controlled.

3. It is convenient to replace different coils to meet the materials of different KG

4. The installation of the observation hole can clear the situation of the crucible material in the furnace

5. Install infrared thermometer or b-type thermocouple, which can accurately measure the temperature of liquid in the crucible

6. With a diffusion pump or molecular pump unit, the vacuum degree can reach 5x10-3

The electrodes and the crucible can be rotated manually outside the furnace, and the liquid can complete the dumping and pouring in the cavity, thus avoiding the danger of pouring and pouring it in a vacuum.

8. Secondary feeding system.

9. The rotation electrode and furnace are used by Wilson seal, good sealing performance and easy rotation.

10. Installation of water cooling machine, water cooling machine with under-voltage and water alarm, safe and reliable.

11. IGBT power supply, with temperature, water protection and alarm, output current display and other functions.

12, VLF series vacuum levitation melting furnace is a dedicated modern high purity smelting equipment, the equipment is high vacuum degree, compact structure, beautiful shape, is a suitable for universities and colleges, institutes and industrial and mining enterprises and other research institute do ideal materials high purity smelting, foundry products.

The product is mainly under the condition of vacuum or protective atmosphere of metal materials (such as titanium, nickel, cobalt alloy), and rare earth magnetic alloy sputtering target materials, polycrystalline silicon, high purity rare earth metals smelting and refining.

 

II. Suspension melting furnace is a bit

1. Metal materials that can smelt high melting points;

2. Because there is no impurities from the crucible, it can smelt ultra-high purity metallic materials and active metal materials;

3. Due to strong electromagnetic stirring, the composition of the components can be uniformly made of alloy, which is not affected by the proportion of the composition of the smelting materials;

4. Shorten melting time and achieve rapid melting;

5. The damage to the water-cooled copper crucible is smaller, and the water-cooled copper crucible has good service life.

6. Soft contact between water-cooled copper crucible and molten metal liquid reduces the cooling load of the crucible, reduces heat loss and reduces energy consumption;

7. Molten metal can be poured out of the crucible without contact.

8. Can melt any shape of the filling material, such as block, powder, sheet, chip, sponge, etc.

 

Iii. Temperature control system

Temperature control system, there is a temperature measuring system of temperature control instrument, on the furnace body is equipped with B type thermocouple and infrared thermometer, thermocouple or infrared thermometer to output the voltage signal is converted to a temperature signal by temperature control meter, temperature control table can control the output control of induction furnace control signal, so to form a closed loop, the temperature of the furnace can be programmed control, can be 30 program temperature control, accurate temperature control precision, the heating rate is adjustable, and constant temperature, can facilitate the control of casting temperature control.

                             

IV. Water cooling system (optional) : water cooling is required on induction furnace and water-cooled crucible.

 

V. structure description

This product consists of furnace cover, furnace body, rotary mechanism, pouring device, pneumatic system, vacuum system and IGBT power supply control system

1. Furnace: stainless steel structure.

Using double water-cooled furnace shell structure, which can guarantee the temperature of the bof shell is not more than 60 ℃.

The opening of the furnace cover is manual, with a locking device and a view hole on the cover of the stove to observe the situation in the furnace.

2. Furnace rack: welded into the frame structure of steel plate, the furnace body is installed on the rack.

3, slewing mechanism, and the furnace with the flange connection, the induction coil by brass around into a spiral from the furnace body, Wilson seals, sealing is reliable, the crucible may be passed on the induction coil rotating mechanism at any Angle of rotation to complete melted liquid and dumping of casting.

4, vacuum system, adopting secondary pump, that is, a diffusion pump, molecular pump) and a straight league pump, vacuum unit is equipped with high vacuum flapper valve and vacuum release valve and charging valve KF fast connection.

5, power supply control system: IGBT suspended dedicated power supply, digital circuit, such as electrical system with over-current, over-voltage feedback and protection circuit, electric control by Siemens standard screen box production, high precision temperature control, easy to operate.

6. Water cooling system: composed of various valves, pipes and other related devices, and equipped with sound and light alarm and automatic cut-off of heating power.

7. Water temperature test: the water temperature of the water cooled copper crucible will be tested with a thermometer, and the temperature will be automatically protected when the temperature is too high, so as to avoid the burning of the copper crucible.
