Vacuum induction melting furnace
1. Product Introduction:
Vacuum induction melting furnace systems are commonly used for metals, alloys, or special materials. Melting occurs in ceramic or graphite crucibles under high vacuum, medium vacuum, or various gases/atmospheres. The molten material is then shaped according to process requirements, enabling experimental, pilot, or production-scale forming.
2. Main Applications:
Melting; remelting and alloying; degassing and refining; homogenization melting; recycling; metal distillation purification; thermal reduction purification of metal elements; casting; directional crystallization; single crystal growth; precision casting; sheet, rod, and wire materials
3. Application Range:
Precious metals; high-purity, high-alloy steel; iron, nickel, and cobalt-based high-temperature materials; non-ferrous metals; solar silicon crystals and special materials; special or super alloys;
4. Product Classification:
4.1 According to the weight of the melting material (in terms of Fe): 50g, 100g, 500g, 1kg, 5kg, 10kg, 25kg, 50kg, 100kg, 200kg, 500kg, 1T, 1.5T, 2T, 5T;
4.2 According to the working cycle: periodic, semi-continuous
4.3 According to equipment structure: vertical, horizontal
4.4 According to heating method: resistance heating, induction heating
4.5 According to process performance: alloy melting, metal purification, precision casting, special forming (sheet, rod, wire)
5. Structural Features:
5.1 Precise temperature control minimizes crucible-melt reactions;
5.2 Different process programs can be used for different types of steel and alloys; convenient process cycle control;
5.3 High application flexibility; suitable for modular expansion or future supplementary changes; modular structure system;
5.4 Optimized matching of medium-frequency power supply and induction coil electrical parameters, resulting in low energy consumption and high efficiency;
5.5 Appropriate intermediate vessel slag removal and filtration technology is used during casting;
5.6 Using appropriate flow channels and intermediate vessels, oxides can be removed effectively.
5.7 Different sizes of crucibles can be configured, offering high flexibility;
5.8 The crucible can be tilted at full power;
5.9 Low alloy element loss, minimal environmental impact;
5.10 Automated control of the melting and casting processes is achievable;
5.11 Wide pressure range selection from slight positive pressure to 6.67X10-3Pa;
5.12 Short vacuuming time and production cycle, increased process integrity and product quality through automatic casting control;
6. Structural Overview:
6.1 Composition
The vacuum induction melting furnace system consists of the following basic modules:
Furnace body, vacuum unit, melting power supply and control system (electrical, pneumatic, cooling), melting and casting equipment, and special forming devices. These modules can be freely combined in different configurations, and a large number of optional additional devices are available.
