Product Description
6300 kVA Semi Closed Silicomanganese Production Line
The 6300 kVA semi closed submerged arc furnace is a high capacity unit for large scale silicomanganese alloy production. Semi closed design keeps a negative pressure hood over the furnace for smoke capture while allowing flexible charging and tapping operations, giving a practical balance between investment cost and environmental compliance for plants running 330-350 tons of SiMn 6517 per day.
Core Structure
- Furnace shell: diameter 11500 mm, bath depth 3600 mm, water-cooled shell with replaceable copper cooling plates on the upper zone.
- Electrode system: three self-baking electrodes Ø1000 mm with hydraulic slipping, automatic paste charging and electrode position closed loop control.
- Transformer: 63000 kVA three-phase furnace transformer, 110 kV or 35 kV primary, secondary 280-420 V, on-load tap changer with 27 steps.
- Tapping: hydraulic tilting furnace body and automatic tapping machine, two tap holes working alternately to shorten tap-to-tap time.
- Charging: belt conveyor with weighing hoppers, batch computer and distributing chutes for uniform burden distribution.
- Dust removal: semi closed hood with low temperature bag filter, air volume 250,000 m³/h.
Working Principle
Weighed raw materials are charged continuously into the furnace. Heat is generated by the three-phase arc and by the resistance of the burden itself. The molten alloy collects at the bottom, the slag layer floats on top and protects the melt from oxidation. Alloy is tapped on schedule, refined in the ladle and cast by a casting machine, while slag is water granulated. A batch computer records the consumption of ore, coke and flux per heat so the operator can keep the alloy grade stable.
