Qatar Steel Company
Austria based Siemens VAI Metals Technologies, a world leader in solutions, technology and services to the mining, iron and steel making sectors, has received an order in the double-digit million-euro range to modernize the Qatar Steel company’s steelworks in Masaieed, Qatar. Siemens VAI Metals Technologies and Siemens W.L.L Qatar are implementing the project jointly. Siemens VAI is a part of the Industry Sector of global engineering major Siemens AG (Munich, Germany). Qatar Steel Company was formed in 1974 as the first integrated steel plant in the Arabian Gulf. Commercial production commenced in 1978 with the company becoming wholly owned by Industries Qatar in 2003. Today, Qatar Steel is widely recognized as a foremost leader in the steel industry, extending its pioneering commitment from an expansive mill site located in the heart of the progressive Mesaieed Industrial City - 45 kilometers south of the nation’s capital, Doha. The Company also operates a UAE based subsidiary - Qatar Steel Company FZE. Qatar Steel plant facilities have come to include a Midrex process based DRI/HBI Combo Mega Module, Electric Arc Furnaces with a Ladle Refining Furnace, a Continuous Casting plant and Rolling Mills with the latest automated features. Other auxiliaries include well-equipped Jetty facilities, a Main Power Substation, Quality Control Center, Maintenance Shops and facilities for sea/fresh water, compressed air, natural gas and a Clinic.

The purpose of the project is to increase billet output capacity by up to 30%, simultaneously reducing specific consumption values and waste gas emissions. The modernized plant is scheduled get into operation by the middle of 2012. 

Siemens will be supplying a 95 MT electric arc furnace (EAF), a 95 MT ladle furnace, a 5-strand continuous billet casting plant and the associated ancillary equipment for the Qatar Steel works at Mesaieed Industrial City, which is located at about 50 km away from Doha, the capital of Qatar. A new dedusting plant is also being installed in the works, which is expected to considerably reduce the emissions from steel production. The scope of supply is rounded off by a system for charging the electric arc furnace with DRI and an alloying facility. Siemens Qatar will look after all the local services.

SAIL’s Modernization - Places order with SIEMENS
Siemens RH Vacuum Degassing Plant
RH Vacuum Degassing Plant
As a part of modernization and expansion program for its Rourkela Steel Works in Orissa, which is intended to increase raw steel production to around 4.2 million tons per year, SAIL (Steel Authority of India) has recently placed an order with Siemens VAI Metals Technologies to supply an RH vacuum degassing plant to RSP. The new plant will allow high-quality steel grades up to cold-rolled non-oriented types to be produced. The order is worth €10M. The RH plant is scheduled to come into operation by the middle of 2012.

The main functions of the RH degassing plant in the Rourkela Steel Works are the removal of hydrogen, forced decarburization and the chemical heating of the liquid steel. The liquid steel is treated under vacuum conditions with argon as lift gas for circulation of steel. Twenty-four heats can be treated per day, which amounts to a production capacity of about one million tons of liquid steel per annum. The Siemens RH plant has a capacity of 150 tons, and is designed as a Mono-block design vessel with welded snorkel tubes. The RH-vessel is raised and lowered by a winch system.

Rourkela Steel Plant was the first integrated steel plant in the public sector in India and also the first in Asia to adopt the LD technology.  This order is unique in the sense that it has re-started the relationship between Siemens VAI and RSP in bringing about further enhancement of technology for production of special grades of steel. A third BOF converter will be constructed in Steel Melting Shop II  with secondary steelmaking facilities – including the Siemens RH plant, and a continuous slab caster.

Siemens LiquiRob Technology: First installation by Riva Group at the electric arc furnace

- No comments

liquirob technology

The Riva Group has become the world’s first steel producer to use the Siemens LiquiRob technology at an electric arc furnace. LiquiRob improves operational safety and increases precision of measurement and sampling. The robot system has been installed in its French plant in Neuves-Maisons where it handles sampling and temperature and Celox measurements. Operating personnel now no longer need to enter potentially dangerous areas, which has substantially increased industrial safety. The system is designed for fully automatic operation and enables precise and reliable measurements to be made at frequent intervals. The acceptance certificate was issued mid-March.

The Neuves-Maisons works produces rebars and coils, and belongs to the SAM Division of the Riva Group based in Milan, Italy. The plant produces steel in an electric arc furnace with a tapping weight of 150 tons and a ladle furnace. The steel cast on a six strand sequential billet casting plant, from which the billets pass on to a rolling mill for further processing. The solution implemented in Neuves-Maisons also includes installation of three automated magazines to store the sample and measuring, which can be safely filled by the operating personnel one time per day outside the dog house. The sampling and measuring procedures can be run completely automatically.

Until recently, the operating personnel had to enter the dog house to take samples and measure the temperature and oxygen activity of the liquid steel using a manipulator. These dangerous and strenuous activities are now handled by the LiquiRob System which accesses the steel bath directly through a window in the slag door. The robot system is operated and monitored from a central control room. Siemens was responsible for integrating the LiquiRob System into the existing Dog house and the EAF automation system, as well as for commissioning, and training the operating personnel. Siemens developed LiquiRob specifically to improve industrial safety and the quality of measurements under the harsh operating conditions encountered in the iron and steel industry. The system was implemented for the first time in 2008 in the Gwangyang Steel Works of the Korean company Posco. There, LiquiRob is used for sample taking, temperature measurement within the distributor and for casting powder dosing on the casting platform of a two strand Slab Caster.
