50kg to 500kg Mini DC Electric Arc Furnace for Experiment.
50kva to 500kva Mini DC Electric Arc Furnace for Experiment.
Main Introduction:
Submerged Arc Furnace is also called as resistance arc furnace. Its electrode is inserted into solid material (such as concentrate ore or raw ore) or liquid molten mass. It melts the furnace materials by the micro arc heat came out between the electrode and furnace material, as well as the resistance heat of the molten mass. (When the voltage is high, furnace materials are mainly melted by arc heat. So it also called as Arc Melting Furnace).
Main application of Submerged Arc Furnace:
1. Melt every kind of ferroalloy, such as ferrosilicon, ferrochrome, ferromanganese, ferronickel, industrial iron, sliicon-alumininm, calcium-silicon alloy, rare earth alloy, etc.
2. Extraction of some non-ferrous metals
A: Using copper sulfide concentrates to produce copper matte, Using nickel sulfide concentrate to produce low grade Nickel.
B: reduction smelting of plumbum ore, tin ore, zinc ore to produce lead bullion, crude tin and crude zinc.
C: smelting of plumbum, tin, zinc dust.
D: Recycling every kind of metal in slag.
F. Overheating and holding the molten materials.
3. For producing Calcium carbide, yellow phosphorus, as well as fused corundum, magnesia
4. Smelting and recovering of solid waste metals, such as slag, scrap iron, metal grinding wheel ash, spent catalyst, electroplating sludge.
Classification of Submerged arc furnace:
Submerged arc furnace is divided into AC and DC Submerged arc furnace according to power supply type
Submerged arc furnace is divided into single electrode, three electrodes and multi-electrode submerged arc furnace according to the number of electrodes
Submerged arc furnace is divided into stationary and tilting type submerged arc furnace according to furnace boy type.
Small capacity submerged arc furnace is generally for experiment. The small arc furnace is usually with DC power supply, single electrode and tilting type due to the restrictions of electrical conditions and crucible size.
The three-phase alternating current (ac) power supply is rectified with positive pole and negative pole output. The positive pole is connected to furnace bottom, while the negative pole is connected furnace top graphite electrode.
Small dc submerged arc furnace is usually single electrode.
Configuration Principle is as below:
Arc furnace transformer and rectifier
