made into a rolled coil of steel. The coil is shipped or sent to a cold mill. The cold roll mill reduces the thickness further. Annealing and galvanizing is done on the steel to meet the specifications of its intended use. Recycled steel or scrap steel is melted in an electric arc furnace, and joins the processes as molten steel.

12.5.1 Steel Minimills 12.5.1.1 General The U.S. steel industry produced about 106 million tons of raw steel in 2006, and approximately 93 "minimills" that recycle ferrous scrap metal accounted for 57 percent of the total U.S. steel production. The production of steel in minimills has increased dramatically over the past 30 years.

MM Integrated Steel manufactures its own steel products. In Lusaka the company has two factories – one is a cold rolling mill and the other a galvanising plant. The cold rolling process involves the conversion of hot rolled coils into cold rolled coils by reducing the thickness of the coils from about 2mm to 0.18–0.5 mm. resp.
Mini mills and specialty producers process steel through some subset of the full range of processes found in integrated iron and steel mills. Typically, they enter the process by melting scrap steel in an electric arc furnace, bypassing the iron-making process and attendant support activities such as sintering and coke making.

Schematic Process flow of an integrated steel plant. Because every process step poses individual analytical requirements, there is no single analytical technique matching all requirements. In fact, multiple, complementary techniques are used and will become more imperative to optimize cost and quality.
The steel industry demands large quantities of raw material and energy to produce iron and steel. During the overall process, parts of the generated by-products are combustible gases, which can be valorized in different equipment of integrated steel mills.

In steel industry, integrated steel mill and electric arc furnace (EAF), referred to as mini-mill, are two steel production routes. In integrated mill, iron ore is the primary raw material which is charged to blast furnace (BF), whereas mini-mill is charged by almost scrap. EAFs rapidly evolved due to their lower production costs,
As shown in the process flow diagram (Figure 1), an integrated steel mill has an interlinked energy network in which the blast furnace gas (BFG) …
The potential for energy savings of an average steel mill is estimated. Pinch analysis is used to optimise an integrated network of heat exchangers. Proposed networks may save up to 3.0 GJ per tonne of hot rolled steel. Limited savings may be obtained from the integration with other industries.
mills and are generally categorized as separate classes of product. 2.1.2 Plant Types Integrated plants produce hot metal (pig iron) from iron ore and coke in a blast furnace and then use the hot metal, in combination with small amounts of mainly internally generated scrap (own scrap), to produce steel in oxygen-blown vessel. Most flat rolled

The decline of large integrated mills and the rise of smaller, less expensive mini-mills is evidence of this. The integrated steelmaking process begins in some integrated mills by producing "coke" from bituminous coal in what is called a coke oven. Coke is a solid carbonaceous residue derived from low-ash, low-sulfur bituminous coal.
• Integrated IFB beams with under-tied hollow sections to create a span of 12,5 m, which is 30% larger than is possible with integrated beams. These beams are exposed usually. • Fire engineering, using natural fire approach, led to a fully unprotected steel structure. • These operating conditions for the water-cooled slab are:
