Competence for the Steel Industry
Relevance of Automation in Steel Industry
India is always looking for innovations and new technologies to manufacture steel.
After liberalisation of the steel sector in India, a large number of new steel projects
have come up with most advanced technologies.
Scenario of Stainless Steel
Axel Fredrik Cronsted (Sweden) discovered Nickel on 1751 and Nicolas Louis Vauquelin
(France) discovered Chromium on 1797. First patent on Austenitic Stainless Steel
was granted to Eduard Maurer (Germany) in 1912. It took 161 years to produce stainless
steel, even after the discovery of Nickel. On 1913 Henry Brearly (UK) produced Martensitic
Stainless Steel and Elwood Haynes (US) was granted a patent on Ferritic Stainless
Steel in 1919.

Pellets – the ‘Dependables’ of steel
It seems that steel mills in the country of India are depending on pellets on a
larger extent tagging the same as a raw material – thanks to the shortage of iron
ore in this country. The dependability factor is set to rise approximately by 13
percentage points in the next two years, being 2015.
Lack of iron ore causing hiatus to small steel companies
Small and medium steel companies in India are facing the storm, and it’s lack of
iron ore. As per recent data by the Joint Plant Committee, the non-alloy and carbon
steel segment saw a downfall of 2.1 per cent in production in the April-November
2012 period. Largely, the decline in production stood at 1.6 per cent. Total production
in the segment stood at about 27 million tonnes (mt), a little more than the combined
output of the main and major producers.
Demand in construction results in high steel prices
A renaissance in construction field witnessed a rise in steel prices. Post a series
of up and downs, the surging demand of the related field extended this price rise
in the Indian market. It is being cautiously watched as steel prices are incessantly
rising due to higher cost of production on an expansion in input cost.
3tn: Efficient material handling and better overview in steel service centers
The technical warehouse management system TWMS/metals controls and visualises transport
and storage activities in the metals industry from continuous casting through to
the shipment of the finished products. It optimises the use of storage capacities
across various warehouses or even plantwide, ensuring that the means of transport,
such as cranes or cross transfer systems, are efficiently used.
Tata Group : Crossing the Lines and Going Strong
The Tata Group stands today as the industry major pacing ahead bagging effective
amplitude. However, the journey was not as smooth as it would have been, by the
by, the Group had to cross series of lines and as days are passing by, the assemblage
is going strong.

in Europe serving since years the market for High Strength Martensitic Steels. The
heart of the installation (see schematic below) is the furnace section with its
water quench unit and pickling unit allowing extremely high cooling rates to obtain
the required mechanical properties for the special steel grades of this market.
SSAB is not only advanced in this cooling technology but also sets new standards
in the environmental protection and use of energy.
The most modern and cost-effective DRI technologies
The gas-based DRI process works by circulating a reducing gas through a moving bed
of particulate iron ore at temperatures up to 1,000oC. Oxygen is removed from the
iron ore by chemical reduction for the production of highly metallised DRI. Thanks
to the successful start-up of the first Energiron plant at ESI (Abu Dhabi), Danieli,
with their partners Tenova HYL, is the new world leader in the DRP technology. The
high energy efficiency and environmental friendliness of the process combined with
a high flexibility both in productive capacity and product quality, independently
from raw materials, make the Energiron Direct Reduction plant the best solution
to be competitive in steelmaking.

used in the papermaking and printing processes utilise more than 500 tapered roller
bearings. These bearings are also used for all the steps that are involved in the
process of printing, starting from printing to packaging.
IRON & STEELMAKING
Optimised secondary steelmaking: oxygen and sulphur partition models in a new Level
2 system for LF-VD
Danieli has recently developed a new Level 2 system to optimise the control of the
LF-VD process. This new Level 2 is now succesfully running in several steel plants,
and will also be used in others. The metallurgical models developed for the new
Level 2 system are based on the dynamic calculation of the steel-slag composition
in various process steps to continuously control and optimise the refining process.
The component models involved in the new Danieli L2 system and their general usages
are listed in Table 1. The calculations of the models are iterative.
