Product Description
1. Electric arc furnace
Electric arc furnace is using electricity as fuel source, and utilizes the arc high temperature produced by electrode and furnace charge to heat and melts the furnace charge. It is widely using in production of normal steel, high quality carbon steel, various alloy steel, stainless, various ferroalloys. It is the key equipment in steel making factories, foundry factories, ferrous alloys making factories and etc.
Characteristic:
Smelting temperature is flexible to be controlled, production needs.
High heat efficiency, atmosphere inside furnace can be controlled.
Can remove the phosphorus, sulfur, oxygen and other impurities and improve steel quality.
Easy to control the chemical composition of steel, stable and high recovery rate of alloys.
Equipment is simple and shorter technological process.
Adoption of new technology:
Optimization design
Tubular water cooled furnace wall and furnace lid
Eccentric bottom tapping (EBT)
Copper-steel combined electrode arm
Cluster type large sectional area water cooled cables
Optimize large current system structure (energy-saving type)

2. Submerged arc furnace Profile
Submerged arc furnace is also known as electric arc furnace or resistance electric furnace. It is mainly used to reducing smelting ore, carbonaceous reducing agent and solvent etc. Mainly adapt to production of ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicon manganese alloy and other ferrous alloys, it is an important smelting furnace in metallurgical industry for production of industrial raw materials and calcium carbide and so on chemical raw materials. The working character is to use carbon or magnesia refractory materials as furnace lining, use itself roasting electrode. Electrode insert into the materials inside the furnace for submerged arc operation, using arc energy and current through the materials, and due to the resistance of the materials and produce energy to melt metal. It is a kind of industrial furnace which is worked continuously, charge material in succession, and tap out metal or slag in intermittent.
Submerged Arc Furnace---Structure characteristics
Submerged arc furnace is a kind of industrial furnace which consumes much power. Full set equipment mainly consists of furnace shell, fume hoods, lining, short net, cooling system, exhaust system, de-dusting system, electrode shell, electrode lifting system, loading and unloading system, electrode holder, arc burner, hydraulic systems, submerged arc furnace transformer and various of electrical equipments.
