The temperature of the bath is then increased to the required value. These reactions are exothermic since they generate large quantities of heat. Depending upon the requirements of the finished products, CONARC process is followed by a ladle furnace or a vacuum degassing unit.

The CSP is capable of producing strips of thickness as low as 0. It 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 consisting of steel processing, distribution cinarc and retail outlets under the brand – Essar Hypermart.

After donarc the top oxygen lance is brought into position, and the blowing of oxygen is initiated. Ocnarc this arcing phase, the remaining solid charge material like scrap or DRI is charged into the bath so as to achieve the desired tapping weight of the heat.

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.

The other important systems include raw material and flux feeding systems and gas cleaning and energy recovery systems. Your email address will not be published. Essar Donarc announces commissioning of its second unit of Conarc Furnace with a capacity of 2.

The objective for the development of this process was to utilize the cinarc of both the conventional top blown converter steelmaking and electric arc furnace EAF. Option is available for introducing bottom stirring devices integrated to the bottom of each of the furnace shell.

A two stage boiler system is used for the waste heat recovery. Home Essar Hypermart Login Contact us. Posted by Satyendra on Apr 17, in Technical 1 comment.

The basic equipment of CONARC process consists of two identical refractory lined furnace shells, one slewable electrode structure with one set of electrodes serving both the furnace shells, one electric supply transformer etc. After completion of the carburization process, the top lance is removed by slewing and electrodes are brought into the operating position. In CONARC process, out of two furnace shells, one shell operates in the converter mode using the top lance while the second shell at that time operates in the arc furnace mode.

These components are designed as pressure parts for steam generation.

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 xonarc can be put to further use in the steel plant. Donate Grateful for your donation!

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. 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 firnace in USA and Trinity Coal that owns six mining complexes in USA that hold an estimated million tonnes of coking and thermal coal.

In the first stage, the waste gas from the CONARC process is led through a boiler system consisting of a swivel type elbow, a post combustion chamber and a hot gas line furnacs cooled to deg C.


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. Charging of cold material also help to protect the furnace shell from overheating.

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.

The basic concept of CONARC process is to carry out decarburization in one shell and electric melting in another vessel.

CONARC Process for Steelmaking

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 production of all grades and qualities of steels covering a wide range from carbon steels to stainless steels.

Essar Furjace has installed continuous caster of 1. The Conarc Furnace will be fed with inputs from Blast Furnace with a capacity of 1. After temperature is achieved, the arcing is concluded and the heat is deslagged before the heat is tapped into the teeming ladle.
