Tata Refractories Limited (TRL)

TRL has achieved the highest straight life of 99 heats in the LD-2 steel ladle of 160 MT capacity with Alumina Magnesia Carbon (AMC) bricks in the metal zone recently. It is reported that the erosion was quite uniform and the ladle was having potential to go up to 105 heats although, it was put down considering the risk factor associated to this.

In another instance, Tata Refractories Limited (TRL) achieved the highest life of 83 heats in SMS-1 ladle of SAIL’s (Steel Authority of India Ltd) Bokaro steel plant surpassing the previous best of 77 heats with its TATA FRT – 2 bricks. Following these achievements TRL congratulated Tata Steel LD-2 team and BSL Refractory and SMS-1 team of SAIL Bokaro for rendering all support.

Tata Refractories Limited (TRL) is the No. 1 refractory company in India with an annual production capacity of around 380000 MT. Its refractories works at Belpahar, Orissa is considered to be the largest among all single refractory producing units in the world. The company has a wide range of products having the ability to meet the refractories requirement for all type of industries.

Tata Refractories Limited (TRL) is the only Burnt Dolomite producing company in India and also happens to be the first refractories company to have Integrated Management System (IMS) certified encompassing ISO 9001 :2008, ISO 14001:2004 and OHSAS 18001:2007. 

Siemens to supply RH Vacuum Degassing Plant for Rourkela Steel Works

SAIL’s Modernization - Places order with SIEMENS

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.
