Iron & Steel Industry in India

Iron & Steel Industry in India

The growth in the Indian steel sector has been driven by domestic availability of raw materials such as iron ore and cost-effective labour.

Steel is vital to modern economies and so over the coming decades global demand for steel is expected to grow to meet rising social and economic welfare needs. Meeting this demand presents challenges for the iron and steel sector as it seeks to plot a more sustainable pathway while remaining competitive. However, through innovation, low-carbon technology deployment and resource efficiency, iron and steel producers have a major opportunity to reduce energy consumption and greenhouse gas emissions, develop more sustainable products and enhance their competitiveness. Considering both the challenges and the opportunities, it analyses the key technologies and processes that would enable substantial CO 2 emission reductions in the sector. It also assesses the potential for resource efficiency, including increased reuse, recycling and demand reduction.

The improved plant performance gives rise to the higher quality improvement and lower cost, and simultaneously environmental friendly plant operation.

The control systems and field instruments are working at the various processes of the iron and steel plant. The process of iron and steel plant is starting from Sinter plant, Coke oven etc, and the blast furnace, iron pre-treatment are following.

Under such circumstances efficient operation is achieved by such measures as increasing the calorie value of fuel gas and recovering waste heat from gas. To further improve combustion efficiency and save energy, measurement of the oxygen concentration in exhaust gases is required.

The measurement of oxygen concentration in the furnace is essential. We have much experience in the area of instrumentation of not only the area but also all iron and steel process.

Overview and Problems. The pickling process removes the contaminants from the metal's surface by using acids without damaging the metal's surface. Our shared goal is customer satisfaction through operational excellence. Yokogawa has brought true innovations to industry. We are committed to ensuring accuracy, reliability, and safety of your production system throughout your business life cycle.

Our comprehensive solutions and expertise help you achieve more results with less total costs of ownership. Below key technologies shall aim for your operational excellence. DPharp Pressure Transmitters with digital silicon resonant sensor delivers the maximum benefits from the elasticity of the single crystal silicon material while enhancing sensitivity and repeatability.

The properties of the resonators remain constant for a long team. This makes DPharp the ideal pressure sensor for harsh industrial automation environments. DPharp offers the highest stability, repeatability and reliability. Magnetic Flowmeters measure flow volume based on Faraday's law. The frequecy of excitation current given to coils affects in the measurement accuracy and response time. With dual-CPU construction, manual control capability and display continues even if an abnormality occurs on one of the CPUs.

The sample gas burns inside the burner unit and a thermocouple detects the burning temperature increase. The air is introduced from the air inlet and divided to the primary, secondary and tertiary air. The primary and secondary ones are for burning the sample gas and the tertiary is for diluting and stirring the exhaust gas. The sample gas is mixed with the primary air In case of the low calorie gas, the primary air is throttled , and burnt completely by the secondary air.

Then, the combustion temperature generates, and burnt gas is promptly diluted and stirred by the tertiary air. Finally the gas is exhausted out from the top of the detector. The increased temperature is measured with the difference of the electromotive force between the cold junction point located at the air inlet and the hot junction point inside the mixed diluted exhaust gas.

The heating wire wound the burner tip is used for both ignition and preheating In case of low calorie gas. The AXF magnetic flow meter is a sophisticated product with outstanding reliability and ease of operation, developed on the basis of decades of field experience. This combination exceeds all expectations for conductivity measurement in terms of reliability, accuracy, rangeability and price performance. The GC has a built-in inch color touchscreen display that dramatically simplifies operations.

At the touch of the screen, the technician can access all of the analytical parameters and measurement results; displayed in easy-to-understand graphical color screens.

The ZR probe's in-situ measurement method does not require any process conditioning or extractive sampling. This reduces maintenance costs and allows faster measurement response to changes in the process.

The YS Indicator with Alarms is an input indicator that has alarms with two inputs. Two loops can be displayed simultaneously. A high limit alarm, low limit alarm, high-high limit alarm, and low-low limit alarm can be generated for each of the two inputs, and the AND connection or OR connection of arbitrary alarms can be output from a total of 6 contacts. The YS is a manual setter that allows for manually outputting setting signals to controllers and the like.

The YS is a manual setter that allows for manually outputting operation signals to operation terminals. Necessary functions can be selected in accordance with the user's purpose. The YS Programmable Indicating Controller can be tailored for various applications by running a user program, and offers high reliability thanks to Yokogawa's proprietary technology, user friendliness, and expandability.

Iron & Steel Industry in India

Steel is a basic metal used as a crucial input into the production process of many consuming goods which are important to the growth and health of the economy, including construction, vehicles, electrical appliances, and packaging sectors. In general terms, the steel sector can be split into three parts. The first stage of steel supply chain involves the production of raw steel. Countries which do not have a domestic source of sufficiently high-quality iron ore may instead use scrap as an input in their steel production. In the case of steel-melting mill in Thailand, due to a combination of worries about the potential impacts on the environment and the health of nearby communities, and the high costs of investment which make breaking-even difficult, there is no domestic upstream production of steel. Instead, iron is imported in the form of pig iron or billet for further processing. Meanwhile, steel production averaged only 7 million tonnes per year midstream and downstream production Figure 3.

This article summarizes the world steel production by country. In , total world crude steel production was The biggest steel producing country is currently China, which accounted for In and , it started to rise again. Crude steel production contracted in all regions in except in Asia and the Middle East.

Download: Safety and health in the iron and steel industry pdf - 0. The first two chapters deal with the objectives and application of the code. The next two chapters address, within a national framework, the responsibilities, duties and rights of the competent authority, the labour inspectorate, employers, workers and their organizations, suppliers, manufacturers and designers, and contractors, and occupational safety and health OSH management systems and services and OSH reporting. Part II of the code addresses different operations commonly used in the production of iron and steel — from coke ovens to steel furnaces and foundries, to rolling mills, coating lines and recycling. It also covers transport, competence and training, personal protective equipment, emergency preparedness, and special protection and hygiene issues.

Лифт спускался на пятьдесят ярдов вниз и затем двигался вбок по укрепленному туннелю еще сто девять ярдов в подземное помещение основного комплекса агентства. Лифт, соединяющий шифровалку с основным зданием, получал питание из главного комплекса, и оно действовало, несмотря на отключение питания шифровалки. Стратмору, разумеется, это было хорошо известно, но даже когда Сьюзан порывалась уйти через главный выход, он не обмолвился об этом ни единым словом. Он не мог пока ее отпустить - время еще не пришло. И размышлял о том, что должен ей сказать, чтобы убедить остаться.
