Although the vacuum consumable arc furnace may seem ordinary among many products, its distinctive features are undeniable. Baoji Dingsheng Vacuum Thermal Technology Co., Ltd. summarizes the following six key features:
- No Contamination During Remelting: In vacuum, there is no slag or other materials between the consumable electrode and the ingot, so the material being remelted remains uncontaminated.
- Excellent Degassing: During melting, the metal is directly exposed to vacuum, effectively removing gases such as hydrogen, nitrogen, and oxygen.
- Purity of Ingot Structure: Non-metallic inclusions in the metal are lighter and float to the top during melting, resulting in a very pure internal ingot structure.
- Uniform Cooling: The ingot is cooled in a water-cooled copper crucible, allowing rapid and uniform cooling, preventing segregation.
- High Alloy Capability: A large amount of alloying elements can be added under vacuum, enabling the melting of high-grade alloy steels.
- Improved Productivity: Short time from pouring to solidification increases equipment productivity and reduces production costs.
