what are the weakness of iron and steel industries

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 […] The iron ore, limestone, and coke are charged, heated, and then reacted to form a reducing gas, which reduces the iron oxide to metallic iron. Iron and Steel Sector? Find industry analysis, statistics, trends, data and forecasts on Iron & Steel Manufacturing in the US from IBISWorld. 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. Air pollutants from the coke-making process vary according to the point of release from the process and the time the process has been in operation. Coke oven emissions are complex mixtures of gas, liquid, and solid phases, usually including a range of about 40 PAHs, as well as other PICs; notably formaldehyde, acrolein, aliphatic aldehydes, ammonia, carbon monoxide, nitrogen oxides, phenol, cadmium, arsenic, and mercury.

It is the largest private-sector steel company in India. As a result, researchers are shifting attention toward reducing CO 2 emission from this important sector. Structures can be refabricated in large sections. Exposures in the iron and steel industry include silica, cobalt, airborne PAHs, chromium and nickel, phenol, formaldehyde, isocyanates, and various amines. By 1990 less than 5% of US steel was produced by the open-hearth process. TABLE 34.15. Iron making: It is the term used to describe how iron is produced in large, refractory-lined structures called blast furnaces. 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. Up to 35% of the initial coal charge is emitted as gases and vapors. Steel can be around 1000 times stronger than iron in its pure form. Roasting and concentrating the ore prior to ferroalloy production produce particulate matter and oxide emissions; SO2 and CO are released during reduction; and casting produces metal oxides and fumes.
