Introduction to Iron and Steel A few definitions and general descriptions are in order Pig iron: Raw iron, the immediate product of smelting iron ore with coke and limestone in a blast furnace. Pig iron has a very high carbon content, typically 4-5%, which makes it very brittle and not very useful directly as a material. A Selection of Mechanical …
8 The environmental impact of steel production Steel production has a number of impacts on the environment, including air emissions (CO, SOx, NOx, PM2), wastewater contaminants, hazardous wastes, and solid wastes. The major environmental impacts from integrated steel mills are from coking and iron-making.
Without limestone or lime, there would be no steel for our cars, computers or construction industry. For every metric ton of steel rolling off the production line, up to 50 kg of limestone and 100 kg of lime are required.
In general, there are four stages of production for stainless steel mill products, as shown in figure 1: (1) melting or refining raw steel, (2) casting the raw steel into semifinished forms, (3) hot-rolling the semifinished forms into flat-rolled products or long products, (4) cold-rolling the hot-rolled products. The production of stainless steel mill products …
