What is an electric arc furnace?

Electric arc furnace is a type of industrial furnace that uses alternating electric current to produce heat. These furnaces serve as an alternative to traditional blast furnaces and play a major role in global steel production. In the electric arc furnace, electric current through steel and other metals inside, leading to fast and efficient steel production. This type of furnace can also be used to process iron, metal alloys and minerals. The roof of the unit is generally removable to be added raw materials. Three metal electrodes protrude from the roof and each can be modified to control the path of the electrical arch. The finished metal leaves the furnace over the opening high along one side of the unit, above the surface of the molten steel. Most of the electric arc furnace models are also built on a tilting platform, so the finished material can be paid to close forms. Flat goods, such as sheet metal or steel plates, are usually produced using a traditional explosive furnace. Today many steel mills PRIt blows the combination of these products and the difference between them is no longer so well defined.

One of the most important advantages of using an electric arc furnace is its ability to produce steel only metal pieces. Workers discard the metal scrap into the roof of the furnace, where it melts and is used to create a new steel. This feature helps maintain low material costs and also maximizes recycling when reducing energy consumption. These furnaces are also smaller than traditional explosive furnaces and require a lower initial investment. This means that steel mills can be built locally, onlping to reduce transport costs and time.

Nature represents many hazards for workers. When the lid is removed to add the material, the molten steel could spray and out into the work area. Scrap material can also be sent from an open roof due to high levelsHeat inside. Finally, these furnaces require large volumes of cooling water, which is considered to be the enemy environment.
