SP-AM-400A Four Arc Source Smelting Furnace

This device is required to be used at 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 (adding purified water or deionized water)

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

3. Gas: The equipment chamber needs to be filled with argon gas (with a purity of 99.99% or above), and a self-contained argon gas cylinder (with a Ø 6mm double socket joint) and pressure reducing valve are required

4. Workbench: Floor standing, equipment installation area of 2.5M × 1M

5. Ventilation device: required

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

2. Equipment power: ＜ 60kw

3. Equipment working pressure: -0.5MPa

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

5. Extraction speed: Extract from the atmosphere to 7 × 10-3Pa ≤ 30min.

6. Maintain vacuum level: After 12 hours of shutdown, the vacuum level in the vacuum chamber should not be lower than 10Pa

7. Customized molds can be made according to requirements (within the range of φ 150)

8. Sample stage speed: continuously adjustable from 1 to 20 revolutions per minute

To ensure the safe use of the equipment, configure system detection and protection functions, such as water shortage and undervoltage detection and protection, strong current phase sequence detection and protection, temperature detection and protection, vacuum system detection and protection, etc.

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

② Operate the vacuum pump group to evacuate to 10-4Pa, close the manual baffle valve, open the manual valve to pressurize to -0.03MPa,

③ Turn on the welding machine, adjust the current of the argon arc welding machine, and press the arc start button

9. Melting temperature: Max can reach 3500 ° C
