Steel process flow_lines - SlideShare

05/11/2010  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 skelp is heated to forming temperature as the steel winds through a long furnace. Alter exiting the furnace, the skelp

12.5 Iron And Steel Production

The production of steel in an EAF is a batch process. Cycles, or "heats", range from about 1-1/2 to 5 hours to produce carbon steel and from 5 to 10 hours or more to produce alloy steel. Scrap steel is charged to begin a cycle, and alloying agents and slag materials are added for refining. Stages

Metallography of Steels

Phase Diagram. We shall interpret microstructrures in the context of the iron-carbon equilibrium phase diagram, even though steels inevitably contain other solutes, whether by design or as impurities. The diagram is nevertheless useful since the transformation behaviour of austenite does not change dramatically unless the steel has a large concentration of solutes.

Metal forming processes

Sheet forming: Sheet metal forming involves forming and cutting operations performed on metal sheets, strips, and coils. The surface area-to-volume ratio of the starting metal is relatively high. Tools include punch, die that are used to deform the sheets. Classification of basic sheet forming processes.

1A Manufacturing Process for Iron and Steel

The figure shows a flowchart of the integrated manufacturing process for iron and steel using the blast furnace and basic oxygen furnace (denoted BF and BOF hereinafter, respectively), which is presently the most commonly used method (51% of world steel production). After the BF-BOF process, molten steel is controlled to a target composition and temperature and is then cast by continuous casting machine to

How steel pipe is made - material, manufacture, making ...

Steel pipes are long, hollow tubes that are used for a variety of purposes. They are produced by two distinct methods which result in either a welded or seamless pipe. In both methods, raw steel is first cast into a more workable starting form. It is then made into a pipe by stretching the steel out into a seamless tube or forcing the edges together and sealing them with a weld. The first methods for producing steel

Bainite Formation Diagram. At 900 °C a typical low-carbon steel is composed entirely of austenite, the high temperature phase of iron. Below around 700 °C (723 °C in pure iron) the austenite is thermodynamically unstable and, under equilibrium conditions, it will undergo a eutectoid reaction and form pearlite - an interleaved mixture of ferrite and cementite (Fe3C).
