Technical Field

[0001] This utility model relates to the field of electric arc furnaces, specifically an energy-saving electric arc furnace with heat circulation. Background Technology

[0002] The electric arc furnace is fed intermittently through a feeding device. A furnace tamping machine maintains the material surface. An opening device such as a plugging machine or an electric arc burn-through device is used to open the iron tap. The liquid alloy flows into containers such as molten iron ladles and is then transported to the mold for casting. After cooling, the product is placed in the finished product warehouse, while the slag is discharged intermittently through the slag outlet.
