About Induction Melting Furnace
Induction Melting Furnace is major steel producing technology using scrap & sponge iron (directly reduced iron) as main raw material. This technology contributes significant steelmaking capacity in secondary steel sector in India and abroad. It has
Air Pollution
Steel scrap comes from various sources and generally has contaminants/coating etc on it. When this scrap is heated contamination/coating etc. disintegrates from steel and comes out either as slag or becomes air borne, thus causing air pollution. The major source of Air Pollution is :
1. Dust & Dirt
2. Rust
3. Oil & Grease
4. Paint & Galvanized Iron
5. PVC Coated Steel
Selection of Technology for Air Pollution Control Device
The following technologies are usually adopted for Air Pollution Control System in Induction Furnace industry:

Induction furnace We provide middle frequency electric induction furnace from 0.05t/h to 15 t/h, The unit consist of power supply system and melt stove. This furnace is suitable for the melting of all kinds of metals, including steel, iron, color metal and alloys, can be used in fields such as precision casting, sand casting, gold smelting and steel-making. The characteristic is that it has good melting quality, the material is easy to be adjusted, the mixing is even, and it has high melting speed.
Gold Induction Melting Furnace This gold melting machine is designed for 2-10kg, which is suitable for melting precious metal such as gold, silver, copper, zinc, etc. With speedy melting time could be realized within 1-3 minutes. Based on the latest and most advanced IGBT induction technology, this small Gold Melting Kit can saves 15-30% energy than KGPS, 100% full load, with low power consumption. The power supply varies from 8kw-15kw for this series furnace. Power on open water faucet put ceramic crucible in the machineput metal in the cruciblepress heating switchpress stop switchtongs the crucible and pour the metal liquid. 4 kg gold melting furnace Attention: 1.Can't be water-break during using the machine. If happens by accident, it needs to pick up the crucible at once, or the heating coil will be damaged. 2. Don't press the heating switch without crucible. 3. Press stop switch first, then pouring the liquid after the metal melted. 4. If the work is finished everyday, please take away the crucible then shut off power. 5. When water flow indicator light is shut off, it stands for out of water or low water pressure. And now the machine will start the function of protection, the gold melting machine will stop heating.
