Casting of titanium shavings in copper mold in order to perform an analysis of the sample.
• Scrap titanium
• Crucible for melting
Temperature: over 3092°F (1700°C)
Power: 5 kW
Time: 60 seconds
Frequency: 100 kHz
The test was performed with mold that the cast sample is coin-shaped, 3mm high and 35mm in diameter. The casting sample require 20g of titanium shavings. Settings used during the test were Power=100%, Speed=500RPM, and Acceleration=0.1s.
- The titanium shavings are very well cleaned. First with solvents, then with soap and water in an ultrasonic bath, and finally with water.
- The scrap is heated to 600C and held at this temperature until all residue has evaporated entirely. If the scrap is not well cleaned and oil-free, the casting sample becomes very fragile.
- The titanium shavings are pressed into a cylindrical ingot with dimensions H=40mm and D=23mm with a 45-ton presser.
- The casting cycle includes 4 washing cycles. Afterwards, the vacuum pump is switched on during melting and casting. The sample is left to cool down for 1min under vacuum.
- Casting is performed after 100% of the titanium shavings are completely melted and the molten mass of titanium scrap is spread on the bottom of the crucible.
