CONARC FURNACE PDF

Mezilar The mill is capable of producing high strength steels including Dual Phase steel. These reactions are exothermic since they generate large quantities of heat. Conarrc temperature of the bath is then increased to the required value. Cold material like scrap or DRI is added to the furnace to utilize this energy and to avoid overheating of the bath. Essar Steel announces commissioning of its second unit of Conarc Furnace with a capacity of 2. Essar Steel has installed continuous caster of 1.

Zunris The process was developed for using any kind and mix of raw materials like hot metal, direct reduced iron DRI and scrap to ensure highest quality requirements for the conzrc of all grades and qualities of steels covering a wide range from carbon steels to stainless steels.

After temperature is achieved, the arcing is concluded and the heat is deslagged before the heat is tapped into the teeming ladle. The basic concept of CONARC gurnace is to carry out decarburization in one shell and electric melting in another vessel. These reactions are exothermic since they generate large quantities of heat. This energy recovery system on the one hand provides for the required cooling of the gas and on the other hand uses a major portion of the thermal energy for the generation of steam which can be put to further use in the steel plant.

Essar Steel announces commissioning of its second unit of Conarc Furnace with a capacity of 2. The first stage consists of the converter process during which the decarburization of liquid iron is done by blowing oxygen in the liquid iron through the top lance. Essar Steel has installed continuous caster of 1. A two stage boiler system is used for the waste heat recovery. With the commissioning of this furnace, Essar Steel has commissioned all steel making units, iron making and rolling units that are part of 10 million tonne expansion project barring a Corex unit which is slated for commissioning later this year.

Donate Grateful for your donation! Charging of cold material also help to protect the furnace shell from overheating. Option is available for introducing bottom stirring devices integrated to the bottom of each of the furnace shell. It operates eight steel processing and distribution centres globally with an aggregate capacity of over 4 million tonnes.

The temperature of the bath is then increased to the required value. Your furnac address will not be published. After completion of the carburization process, the top lance is removed by slewing and electrodes are brought into the operating position.

After this the top oxygen lance is brought into position, and the blowing of oxygen is initiated. Essar has the largest retail channel through Essar Hypermarts. The mill is capable of producing high strength steels including Dual Phase steel. The second stage is the electric arc process during which the electric energy is used for melting of the solid charge and for superheating of the molten bath to tapping temperature.

Cold material like scrap or DRI is added to the furnace to utilize this energy and to fjrnace overheating of the bath. In CONARC process, out of two furnace shells, one shell operates in the converter mode using the top lance while the second shell furnqce that time operates in the arc furnace mode.

The Conarc Furnace will be fed with inputs from Fuenace Furnace with a capacity of 1. The other important systems include raw material and flux feeding systems and gas cobarc and energy recovery systems.

Alternatively two stationary top lances, one for each furnace shell for the blowing of oxygen can also be used. The technology of this process is based on the increased use of hot metal in the electric arc furnace and is aimed at optimizing energy recovery and maximizing productivity in such an operation. These components furnnace designed as pressure parts for steam generation. With this the second phase known as arcing phase starts.

North American operations comprise a four million tonne steel plant in Canada, iron ore reserves of two billion tonnes and is currently setting up a six million tonne taconite plant in USA and Trinity Coal that owns six mining complexes in USA that hold an estimated million tonnes of coking and thermal coal.

It will also be conacr of the few steel facilities which are fully integrated and will produce the entire range of flat products. Essar Steel commissions second Conarc Furnace.

Options are also available to introduce burners and injectors systems in the shell for the injection of fuel, carbon and oxygen as per the process requirements.

In the second stage, the waste gas is cooled down to deg C in a vertical pass boiler especially developed for this type of application. During this arcing phase, furnzce remaining solid charge material like scrap or DRI is charged into the bath so as to achieve the desired tapping weight of the heat.

In addition, Essar has also invested in various supporting infrastructure at Hazira that include power plants of MW and a all-weather port of 30 MTPA at total investment of over Rs. Posted by Satyendra on Apr 17, in Technical 1 comment.

Essar Group Steel Media Media releases Essar Steel commissions second Conarc Furnace Conwrc is the most versatile flat steel producer with integrated facilities from 5-m wide plates, hot rolling, cold rolling, galvanizing and color coating, pipes with a full distribution business curnace of steel processing, distribution centres and retail outlets under the brand — Essar Hypermart.

During this phase known as converter phase, the content of carbon, silicon, manganese, and phosphorus in the bath are reduced. In the first stage, the waste gas furnade the CONARC process is led through a boiler system consisting of a swivel type elbow, a post combustion chamber and a hot gas line and cooled to deg C.

The CSP is capable of producing strips of thickness as low as 0. Depending upon the requirements of the finished products, CONARC process is followed by a ladle furnace or a vacuum degassing unit.
