Overview of production units

Direct resuscitation unit

Arfa Direct Regeneration Unit by Midrex method with annual production capacity of 800,000 tons of sponge iron and 60,000 tons of briquettes was put into operation in June 2011. This unit managed to record a production equal to more than 5% of its nominal capacity in the first year after its launch. In order to ensure the full consumption of steelmaking with the approach of economic production and job creation, in 1400, a 50% capacity increase plan was implemented without increasing the volume of the recovery furnace for the first time in the world.

Steel making unit

The steel making unit of Arfa Iron and Steel Company was put into operation in June of 2012 and steel production in this unit started in June of the same year. The turning point in the history of the "Arfa Iron and Steel Company" steel plant was achieving nominal capacity in 1996 (the fifth year of production) and producing more than 6% of its capacity in 1997, which is an unprecedented record in the country's steel industry. . In August 1401, with the approach of maintaining domestic customers and increasing the share of exports, they carried out a plan to increase production capacity by 25%. In this capacity increase, in addition to increasing the amount of production, the ability to produce 125x125 mm and 225 mm round sections was added to the company's other production sections, including 130x130 mm, 150x150 mm, and 200x200 mm sections.

Electric arc furnace

The method of producing molten steel in the steelmaking unit of Arfa Iron and Steel Company is the use of electric arc furnace (EAF), which is the cleanest method among the methods of producing molten steel from an environmental point of view. The electric arc furnace used in Arfa Iron and Steel Company is one of the most modern furnaces in the country and the result of modern Italian technology. This furnace with a capacity of 180 tons can produce 3100 tons of molten steel daily. One of its most important advantages is that the electric arc furnace of Arfa Iron and Steel Company's steelmaking unit is equipped with automatic oxygen and carbon injection lances.

Patili furnace

The existing Patili furnace in Arfa has a capacity of 180 tons, with automatic charging, and it is fired from the floor. Due to the fact that quality production is very important for Arfa Iron and Steel Company, in the patili furnace, the molten steel discharged from the electric arc furnace is subjected to blowing operation only by argon (neutral gas) and impurities such as sulfur are separated from it. The work of the Patili furnace is exactly the same as the electric arc furnace, with the only difference being that instead of using the body of the electric arc furnace, the Patil itself is used as the furnace body.

Vacuum Degasser

One of the distinctive features of the "Arfa Iron and Steel Company" steel plant, which distinguishes it from many steel plants in the country, is its use of vacuum degassing and decarbonization (VD-VOD) section. In this section, after placing the steel The molten metal exposed to vacuum and performing other processes, it is possible to produce all kinds of qualitative and alloy steels for sensitive applications. Arfa Iron and Steel Co., with its VD-VOD department and the ability to produce a wide range of quality and alloy steels, can play an effective role in reducing the import of these steels to the country.

Continuous casting

The casting machine in the steelmaking unit of Arfa Iron and Steel Company is of arc type and has 6 casting lines. The casting molds in this machine are equipped with an electromagnetic stirrer (EMS), which makes the produced ingot have a favorable metallurgical structure and the final product prepared from it is of high quality. Also, the presence of auxiliary casting equipment, including subsurface and protected casting facilities, has made the products of Arfa Iron and Steel Company to be free of gas bubbles and have a very favorable surface quality.
