Luoyang Judian Metal Hot Processing Equipment Co., LTD is mainly engaged in the manufacture of complete sets of equipment in the metal thermal processing industry and the integration of the entire production line.
Efficient operation is the key to safe, cost-effective, and high-quality smelting. Medium-frequency induction furnaces are widely used in foundries because they provide fast melting, accurate temperature control, and energy savings. To achieve these benefits, operators need to follow the right charging methods and safety practices.
How to Use Key Materials
Pig Iron
Pig iron should be charged at the beginning of smelting. Its uniform size and high electrical conductivity make it easy to absorb induction current, which speeds up melting and stabilizes furnace performance.
Recarburizer
Recarburizers adjust the carbon content of molten iron, but timing is critical.
Added too early, they stick to the furnace bottom and waste energy.
Added too late, they slow down composition adjustment and may cause overheating.
Ferrosilicon
Silicon affects how recarburizers are absorbed. In medium-frequency induction furnaces, ferrosilicon should be added later in the process. Early addition can increase oxidation and reduce melting efficiency.
Safety Practices During Smelting
Avoid late charging: Adding pig iron with rust or moisture into molten iron can cause violent explosions and splashing.
Check material quality: Always use dry, clean, and properly sized charge.
Monitor furnace conditions: Keep temperature stable and adjust charging carefully to save power and extend furnace life.
Benefits of Proper Smelting Techniques
Faster melting cycles and reduced downtime.
Consistent carbon and silicon levels for better product quality.
Lower power consumption and overall cost savings.
A safer work environment for furnace operators.
