Description
Details
The Smelting Submerged arc furnace is also known as an electric arc furnace or resistance electric furnace.
Mainly used for reducing smelting ore, carbon-containing reducing agent, solvent, etc. It is mainly suitable for the production of ferromanganese, ferrochromium, silicomanganese, and other ferrous metal alloys.
It is an important smelting furnace for the production of industrial raw materials and chemical raw materials such as calcium carbide in the metallurgical industry.
The work feature is the use of carbon or magnesia refractory materials as furnace lining and self-baking electrodes.
The electrode is inserted into the material in the furnace for submerged arc operation, which uses arc energy and current to pass through the material, and generates energy due to the resistance of the material to melt the metal.
It is an industrial furnace that works continuously, feeds continuously, and discharges metal or slag intermittently.
A smelting submerged arc furnace is a kind of industrial electric furnace with huge power consumption.
Mainly consists of furnace shell, furnace cover, furnace lining, short net, water cooling system, smoke exhaust system, dust removal system, electrode shell, electrode pressure release and lifting system, loading and unloading system, controller, burning through the device, hydraulic system, submerged arc furnace Transformers and various electrical equipment, etc.

Features
70% of the reactance of the submerged arc furnace system is generated by the short network system.
The performance of the short network determines that the natural power factor of the submerged arc furnace is difficult to reach above 0.85.
The factor of most furnaces is between 0.7 and 0.8, which reduces the efficiency of the transformer and consumes a lot of useless work.
In addition, manual control and stacking techniques have led to low smelting efficiency and increased electricity and electricity costs.
Therefore, increasing the power factor of the short network and reducing the imbalance of the grid has become an effective means to reduce energy consumption and improve smelting efficiency,
so as to achieve the following effects:
(1) Reduce power consumption by 5-20%;
(2) Increase output by more than 5%~10%
Case
Hani is a well-experienced enterprise; we have more than 20-year experience in manufacturing furnace machinery.
As the China steel industry is going down these years because of the environmental policy from the central government, the international market is developing very fast in these years, we have customers from the Mideast, Asia, India, Africa, and South America, etc, all around the world.
Our Melting Furnace Machinery not only has a ready installed in the domestic market but are also exported to Iran, Ethiopia, Kazakhstan, Thailand, Vietnam, Indonesia, India, Myanmar, Fiji, and other countries and regions.
