4 Heads Vacuum Arc Melting System

Installation conditions

This equipment is required to be used at an altitude of 1000m or less, a temperature of 25℃±15℃, and a humidity of 55%Rh±10%Rh.

1. Water: The equipment is equipped with a self-circulating cooling water machine (filled with pure water or deionized water)

2. Electricity: AC380V 50Hz, must have good grounding

3. Gas: The equipment chamber needs to be filled with argon gas (purity 99.99% or more), and argon gas cylinders are required (with Ø6mm double ferrule joints) and pressure reducing valve

4. Workbench: floor type, area for installation: 2.5M×1M

5. Ventilation device: needed

Major parameters

1. Equipment ultimate vacuum: 8×10^-4 Pa

2. Equipment power: <60kW

3. Equipment working pressure: -0.5MPa

4. System vacuum leak rate: 5.0×10^-7 Pa.l/S

5. Pumping speed: pumping from the atmosphere to 7×10^-3Pa≤30min.

6. Maintain the vacuum degree: the vacuum degree of the vacuum chamber shall not be lower than 10Pa after 12 hours of shutdown

7. Melting crucible: φ100×15mm, smelting 300g

8. Sample stage speed: 1 to 20 rpm, continuously adjustable

In order to ensure the safe use of the equipment, system detection and protection functions are adopted, such as: water shortage and undervoltage detection and protection, strong power phase sequence detection and protection, temperature detection and protection, vacuum system detection and protection, etc.

Product specification

1. After the filling is completed, turn on the power switch of the equipment and adjust the crucible speed (1~20 rpm).

2. Operate the SPD/Pfeiffer HICube80 molecular pump unit to evacuate to 10^-3Pa, close the manual flapper/buffer valve, and open the manual valve to charge the pressure to -0.03MPa.

3. Turn on the welding machine, adjust the current of the argon arc welding machine, and press the arcing buttons (2 pcs).
