what are the weakness of iron and steel industries

TABLE 34.14. Obviously, the volatilized gases are air pollutants. Coke oven gas is comprised of hydrogen, methane, ethane, carbon monoxide, carbon dioxide, ethylene, propylene, butylene, acetylene, hydrogen sulfide, ammonia, oxygen, and nitrogen. The iron and steel industry is one of the largest industrial emitters of CO 2 accounting for about 7% global anthropogenic CO 2 emissions [143]. Deloitte refers to one or more of Deloitte Touche Tohmatsu Limited (“DTTL”), its global network of member firms, and their related entities. Most of the particulate matter is iron or iron oxide. This iron content is higher than that of the Egyptian ore currently used. For example, with steel structures, column-free interiors are achievable, which can give a space a wonderful sense of openness. 3. See Terms of Use for more information. Basic oxygen furnaces (BOFs) have largely replaced open-hearth furnaces for steelmaking. A gradual decline in production has continued; production has decreased from 20 million metric tons in 1997 to 15.2 million metric tons in 2002. Indeed, being an alloy of iron, chromium, nickel, and other elements, stainless steel possesses a host of unique properties that make it highly useful in a variety […] Iron rusts very fast and it needs to be protected from water. Every half an hour or so, the flows of gas, air, and waste gas are reversed to maintain uniform temperature distribution across the wall. Iron and steel industries are generally grouped as steel mills, which produce steel sheets or shapes, and foundries, which produce iron or steel castings. The mines and plants visited represent a cross section of the iron and steel industry with respect to geographic distribution, plant size, and processes used. According to the World Steel Association (WSA), in 2014 world steel production amounted to 1665 mln tonnes - a 1% rise in comparison with 2013. In 1976, the United States was second in the world with 48 million metric tons of coke, i.e. We use cookies to help provide and enhance our service and tailor content and ads. The amount of carbon is small (usually between 0.2% and 2.0%) but it makes a huge difference to the strength. Global iron and steel market Production. Salah M. El Haggar, in Environmental Solutions, 2005. Iron has poor tensile strength and has poor resistance to impact. Up to 35% of the initial coal charge is emitted as gases and vapors. Steel has an aesthetic to it that architects enjoy exploring. Location of these installations are shown in figure 52. In the electrolytic production of nickel, iron is not removed from nickel because nickel will be used for the production of stainless steel. Steel is a particular kind of iron that is approximately one percent carbon, with the carbon content spread throughout the metal evenly. This was an early version of the charcoal blast furnace, and these furnaces that developed in Continental Europe soon spread to Great Britain. Benzene, xylene, toluene, and solvent naphthas may be extracted from the light oil fraction. Moreover, the iron and steel industry is closely related to the chemical industry and light industry. Ferrochrome, ferromanganese, and ferrosilicon are produced in high-temperature furnaces which emit copious quantities of metallic fume and particulate matter. The average growth rate of consumption in 2014 was 3%. Global steel production is also expected to increase by 30% by 2050. Pickling may result in the release of acid mists. The list of leading countries has changed significantly. It shows that the iron and steel industry has the potential to contribute to the competitiveness of national producers and to the growth of the national economy. This over-dependence can prove to be fatal in times of economic crisis. The disadvantages of Iron and Steel industries: High maintenance cost. Steel can be around 1000 times stronger than iron in its pure form. Recent dry granulation processes give the chance to recover a great part of this heat. The Jharia coalfield, the main storehouse of prime coking coal in India, was haphazardly exploited for centuries by both selective and wasteful mining methods. Scrubbing with special solutions may be required for control. 1997). All slag types should be treated as by-products rather than waste materials. The primary difference between iron and steel is that the former is a metal, whereas the latter is an alloy. These programs include detailed exploration for new and deeper deposits and other deposits hitherto considered lost; planning for maximizing extraction using advanced technology; blending lower grade coals with superior coals; improving coal beneficiation techniques; examining the possibility of replacing coking coal with noncoking coals; and improvement, or modification of, conventional steel metallurgy. Sintering: It consists of mixing moist iron ore fines with a solid fuel, usually coke, and then firing the mixture to eliminate undesirable elements and produce a product of relatively uniform size, physically and chemically stable, for charging the blast furnace. Developing countries have a higher level of steel consumption (1,133 mln tonnes). Fortunately, you can control rust by painting, galvanizing, chrome plating or coating the iron with a sacrificial anode, which corrodes faster than the stronger metal. It retains the leading place in construction ahead of wood, competing with cement and interacting with it (ferroconcrete), and still competing with new types of constructional materials (polimers, ceramics). Please see www.deloitte.com/about to learn more. The biggest weakness of Tata Steel is its increasing debt-to-equity ratio. China's steel industry should adhere to the dual-circulation development pattern and accelerate the establishment of a stable and efficient supply system for raw materials, industry experts said. The evolution of both coke and anthracite iron-making paralleled each other in the United States during the 1800s, and by 1856 there were 121 anthracite furnaces in operation. The "World - Bars And Rods Of Iron Or Steel (Hot-Rolled) - Market Analysis, Forecast, Size, Trends and Insights" report has been added to ResearchAndMarkets.com's offering. Air Pollution Emissions and Controls: Iron and Steel Foundries. DTTL (also referred to as “Deloitte Global”) and each of its member firms are legally separate and independent entities. Stylish shapes can be designed in buildings due to the malleable nature of steel, this gives designers a greater freedom when fashioning their ideas. The use of coke then spread to Continental Europe: Creussot, France, in 1785; Gewitz, Silesia, in 1796; Seraing, Belgium, in 1826; Mulhiem, Germany, in 1849; Donete, Russia, in 1871; and Bilbao, Spain, in 1880 [34]. In 1976, the United States was second in the world with 48 million metric tons of coke, i.e. By 1615, over 800 furnaces, forges, or ion mills existed in Great Britain, with 300 of them blast furnaces. JSW Steel Weaknesses Here are the weaknesses in the JSW Steel SWOT Analysis: 1. Examples are chromium (in the form of ferrochrome) and manganese (in the form of ferromanganese) added to steel to improve its strength or hardness, or nickel and chromium added to steel to increase its corrosion resistance. Training and creating awareness among iron and steel workers on the different ways to optimize the use of machines, equipment, processes, and other steps to efficiently operate steel production with reduced CO2 emission. TABLE 34.13. Up to 35% of the initial coal charge is emitted as gases and vapors. Potential emissions from foundry operations, along with the usual control methods, are shown in Table 34.17. INTRODUCTION Steel is a hard, strong grey or bluish-grey alloy of iron with carbon and usually other elements, used as a structural and fabricating material. For example, one type of furnace, the Stuckofen, used in fourteenth-century Germany, could produce 4,000 pounds of iron per day with a fuel rate of 250 pounds of charcoal per 100 pounds of iron produced [34]. Get up to speed on any industry with comprehensive intelligence that is easy to read. The atmospheric emissions from the BOF process are listed in Table 34.16. With coke being the strongest and most available fuel, the evolution of 100 percent coke furnaces continued, with major steps being made in the Pittsburgh area between 1872 and 1913. The amount of steel produced has been used as a measure of a country’s level of industrial development with the big ones such as the USA, the UK, France, Germany, Japan and Russia leading the pack. U.S. raw steel production continues to leap on a weekly basis on an improvement in capacity utilization — a key metric in the steel industry. Structures can be refabricated in large sections. DTTL does not provide services to clients. Sector Industrial Products and Chemicals. Despite all the efforts to exploit coal reserves, with due regard being paid to conservation by India’s nationalized coal industry, it has not been possible to supply enough metallurgical coke, of the required grade, to meet the needs of India’s growing steel industry. The industry produced 29 million metric tons of pig iron and 88 million tons of steel. Control is possible, but the cost of the control may be prohibitive for the small foundry which only has one or two heats per week. Coke oven emissions are actually complex mixtures of gas, liquid, and solid phases, usually including a range of about 40 polycyclic aromatic hydrocarbons (PAHs), as well as other products of incomplete combustion; notably formaldehyde, acrolein, aliphatic aldehydes, ammonia, carbon monoxide, nitrogen oxides, phenol, cadmium, arsenic, and mercury. The use of coke increased iron production because it was stronger than charcoal and could support the weight of more raw materials, and thus furnace size was increased. 14.4% of the world production. Steel-making is commonly associated with coke ovens. The reaction is exothermic, and an entire heat cycle requires only 30–50 min. Changes in Steel-making Processes in the United States. As a result of the depletion of virgin forests in Great Britain to sustain the charcoal iron, the ironmasters were forced to consider alternative fuel sources.
