Steel Mill Process Flow

Nov 05, 2010 Following the flow of the continuous butt-weld pipe mill (left) a coil of flat-rolled steel called skelp is drawn through the line by pinch rolls. A long loop of skelp is created as a reserve so that pipemaking can continue while the trailing end of one coil is welded to the leading end at a new one

The production of steel in an EAF is a batch process. Cycles, or heats , range from about1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrapsteel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stagesof each cycle normally are charging and melting operations, refining (which usually includes oxygenblowing)

The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel scrap

The smelting and refining process for iron and steel in the BF-BOF process involves the carbon reduction of iron ore (Fe2O3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Major reducing agent in the BF is the carbon monoxide gas(CO) generated by the oxidation of the carbon(C) in coke

Steel is typically made in an integrated steel mill (ISM) (see Fig. 16.1), located close to a large river or a deep sea harbour, which typically receives coal and iron ore (oxide, either hematite or magnetite) by ship, usually from far afield, Brazil, Australia or South Africa, for example. The raw materials are blended and prepared to meet the specification for steel production in large

Jul 12, 2016 VOD process is considered to be an important vacuum process for production of stainless steel. It is mainly suitable for special stainless steels which require the very low value of C, N2, and H2 levels. In this process, the ladle is placed in vacuum chamber and there is a provision for O2 lancing through vacuum tight gland and alloying additions
