Vacuum induction melting furnace is one of the most widely used equipment in vacuum metallurgy field. It has been proved that a considerable proportion of the alloys and special steels needed by aerospace, missile, rocket, atomic equipment and electronic industries are produced by vacuum induction melting furnace. For example, when the nickel base, cobalt base and iron base superalloys are melted by vacuum induction melting furnace, their thermal and mechanical properties are significantly improved. Like stainless steel, heat-resistant steel, ultra-high strength steel, tool steel, bearing steel, as well as magnetic materials, elastic alloys, expansion alloys, almost all use vacuum induction melting furnace to melt, in order to ensure material properties and quality.

Application: High Vacuum Induction Furnace Melting 1kg Titanium Alloy
(1)Equipment preparation
High vacuum induction furnace:
Ensure that the equipment is intact and check the induction coil, crucible and cooling system.
Check the status of the vacuum pump to ensure that the required vacuum can be achieved.
Auxiliary equipment
Prepare temperature controller, pressure monitor and cooling water circulation system.
(2)Material preparation
Raw materials:
Select high-purity titanium (≥99.5%) and alloying elements (such as aluminum and vanadium), weigh them in proportion, and the target is 1 kg total weight: 90% titanium (900 grams), 6% aluminum (60 grams), 4% vanadium (40 grams).
Ensure that all materials are free of moisture and impurities.
Crucible selection:
Use quartz or ceramic crucibles suitable for titanium alloy melting to ensure good high temperature resistance.
(3)Operation process
Charging:
Put the weighed titanium and alloying elements into the quartz crucible to ensure uniform distribution.
Close the chamber:
Put the crucible into the induction furnace, ensure that it is properly placed and the furnace door is tightly closed.
Vacuuming:
Start the vacuum pump and gradually reduce the pressure in the chamber to a target pressure of 10-5 mbar. Monitor the vacuum change to ensure there is no leakage.
Heating process:
Set the heating temperature to 1600°C and start the induction heating system.
Observe the temperature change to ensure that the temperature rise is stable and avoid rapid heating that may cause material damage.
Melting and stirring:
When the melt reaches 1300°C, start the electromagnetic stirring system to promote the homogenization of the alloy.
Regularly measure the melt temperature with a thermocouple and perform composition analysis during the melting process.
Casting:
When the melt reaches the set temperature, turn off the heating system, wait for a short period of stabilization, and then start the pouring system.
Pour the molten alloy slowly and evenly into the preheated mold to avoid bubbles.
Cooling and removal:
Let the casting cool naturally to room temperature and monitor the temperature changes during the cooling process.
Remove the cooled casting and check the appearance and surface quality.
Post-processing:
Perform necessary heat treatment (such as annealing) on the casting to eliminate internal stress.
Perform mechanical processing to meet design requirements, including cutting, grinding, etc.
(4)Precautions
Ensure that operators wear appropriate protective equipment throughout the process.
Regularly check the operating status of the equipment to ensure safety.
When working in a vacuum environment, closely monitor pressure and temperature to ensure the stability of the melting process.
