Dimensions & Component Description

Copper Crucible

Water-cooled copper crucible with 5 stations (other numbers of stations can be customized). Each station is a hemispherical pot with a radius of 35 mm (other sizes can be customized). One of the stations is equipped with a suction casting device at the bottom.

Vacuum Suction Casting Device

Vacuum suction casting device can cast metal rods of φ5 mm × 65 mm length (other sizes can be customized). By evacuating the copper mold, the molten metal quickly enters the copper mold, resulting in metal rods with small shrinkage cavities.

Electromagnetic Stirring

The equipment has an electromagnetic stirring function. The three surrounding stations all have electromagnetic stirring. The principle is that the coil generates a magnetic field when energized, and the molten metal moves within the magnetic field.

Main Features

1. Observation windows are installed on the front and left sides. LED lights are installed on both sides at the rear inside the chamber for easy observation of the arc melting process.
2. The vacuum chamber, copper crucible, and arc electrode are all water-cooled.
3. Up/down movement uses a steering wheel design, and the operating lever rotates smoothly.
4. To allow flipping of alloy ingots for multiple melts without breaking the protective atmosphere, the melting furnace uses a manipulator flip mechanism.
5. Small crucible size with multiple stations makes it easy to prepare several samples while avoiding cross-contamination between samples.
6. A suction casting device is installed at the bottom, capable of casting metal rods of φ5 mm.

Vacuum Chamber

Water-cooled vacuum chamber dimensions: Dia 400 × 320 mm. The vacuum chamber has an electrically operated lift door for easy sample loading and unloading. There is a φ80 mm observation window on the front and left sides for easy viewing of the arc melting process. A manipulator is installed on the right side for flipping alloy ingots.
