Submerged Arc Furnace Profile
Submerged arc furnace—it’s 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 adapts 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 self roasting electrode. Electrode inserts 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’s a kind of industrial furnace which is worked continuously, charged material in succession, and tapped out metal or slag in intermittent.

Notes: The above is roughly value. According to the difference of the raw material composition, finished product components, electric furnace capacity and etc. the power consumption value will be much different.
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.
Submerged arc furnace equipment is divided into three layer arrangement
The 1st layer is furnace body (including furnace bottom support, furnace shell, furnace lining), tapping system (including the ladle and ladle car.), arc burner etc.
The 2nd layer
1、Fume hood: At present, mostly of submerged arc furnace adopts closed or semi-closed low hood structure, with the characteristics of environmental protection, facilitate maintenance and improve the operation environment. The closed structure can also collect the exhaust gas (main ingredient is carbon monoxide) which is generated in the production and used in synthetically. Also can reduce the heat loss of the circuit, decrease the temperature of the electrode, and improve the operating environment.
2、Electrode holder: Most of submerged arc furnace with three-phase power supply. Electrode in triangle or inverted triangle, symmetrical position placed in the middle of furnace chamber. Large submerged arc furnace generally adopts anthracite, coke and coal tar pitch mixed as electrode material, in the process of smelting , it roasting by itself as electrode.
3、Short net
4、Copper tile
5、Electrode shell
6、Unloading system
7、Stoking machine
8、Fume exhaust system
9、Water-cooling system
10、Submerged arc furnace transformer
11、Operating system
The 3rd layer
1、Hydraulic system
2、Electrode press and release device
3、Electrode lifting system
4、Steel platform
5、Hopper and cycle material distribution car
Other additional: skew Bridge feeding system, electronic batching system, etc.
- Q: Selection of heat preservation material for industrial furnace
- Micro nano heat insulation board.The thermal conductivity of micro nano heat insulation board is very low, only a fraction of the traditional thermal insulation material, and the insulation effect is very efficient.
- Q: Should the industrial furnace shell cool down?
- If the furnace shell temperature is too high, it shows that the lining is not good or damaged, so it should be repaired in time. If you do not repair, take the cooling way, undesirable. Because this will cause a lot of heat loss, resulting in waste of energy, increase production costs, and affect the service life of the furnace.
- Q: What are the companies in the world that are currently engaged in metallurgical furnaces?
- Each manufacturer has its own industry and technological advantages.If you say that the performance rankings, turnover, and so on, it seems that no one has done this ranking.
- Q: What are the combustion equipments used in industrial boilers?
- The main auxiliary equipments of the general boiler are: upper coal machine, ash blower, blower, draught fan, economizer, feed pump and water treatment unit. Oil boilers are: oil pumps, burners, tanks and so on.
- Q: What is industrial furnace masonry?
- Masonry industrial furnaces refers to complete materials such as brick kilns in construction process.
- Q: What's the role of anchor bricks in industrial furnaces?
- Anchorage brick is a new type of anchor brick relates to an industrial furnace, in particular to anchor brick of an industrial furnace roof, including column hanging end and the anchor structure, opened in the anchor on the surface of the spacing of the grooves in the anchor on at least one surface is arranged along the length direction ribs is provided with ribs, the ribs of the reinforcement and anchorage tension, tensile and flexural strength was obviously improved, the stress generated in the groove at the bar at the barrier can not continue to transfer, so the anchor brick of this kind of structure is not easy to break.
- Q: What are the advantages of a vacuum furnace?
- The utility model can completely eliminate the oxidation and decarburization of the workpiece surface in the heating process, and can obtain clean surfaces without deterioration layers. For cutting tools that grind only one side of grinding (such as twist grinding, the surface of the groove surface is exposed to the blade directly), the cutting performance is greatly improved.
- Q: What is the difference between industrial furnace masonry and ordinary masonry?
- Furnace industry is not generally Mason walls, needs to have a professional operation and rich construction experience, high level of industrial furnace is difficult to get.
- Q: How to use industrial furnace equipment?
- If it is water cooling furnace door, but also to ensure the smooth flow of pipes, winter pipes are not frozen. When the boiler is in a limited position, the interlocking device for cutting off the power supply shall be provided when the furnace is in and out, and the number of broken wires in the pitch of the steel wire shall not exceed 10%, and the counterweight of the furnace door shall be reliably hung.
- Q: Brief introduction to repair of industrial furnace
- The industrial furnace is the main production equipment in the machinery industry. The repair of industrial furnace directly affects the quality, high yield, long life, low consumption and safe production of the furnace.
