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 ...
The manufacturing process of TMT Bar involves series of processes like rolling, water quenching, heat treatment, cooling at various stages of manufacturing. The Thermo Mechanical Treatment involves 3 essential steps that are: Quenching. Self Tempering. Atmospheric cooling. The quality of TMT Bar depends on three major factors.
The commercial processes for making steel are : (1) Bessemer process (2) LD process (3) Openhearth process (4) Crucible process (5) Electric process (6) Duplex process. The Bessemer, open hearth and electric process can be subdivided into (a) acid process and (b) basic process, according to the type of lining used in the furnace.

For hot rolling of metals they are first cast into ingot moulds of suitable form (rectangular, square or round). The size of ingot depends upon the metal to be cast and the endproduct desired. For hot rolling, the ingot is removed from the mould after solidification when it is hot and placed in the gas fired furnace called soaking pits.
When sheet is entered between a pair of rolls and any kind of force applied to that sheet, like that generated when making a reduction, the rolls, since they are supported at the roll ends, will bend around the sheet. This will tend to make the sheet relatively thick in the middle and thin on the edges. On thin sheet, this will be seen as wavy edges.
Analysing metal working processes. G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap.
What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled. If the temperature of the ...
In recent years, material flow scheduling has been extended to the upstream hot metal transport [40] and downstream hot rolling mill [43]. With the development of material flow scheduling, modern iron and steel production processes have become more and more compact and the total metallurgy time has become shorter and shorter.

The smelting and refining process for iron and steel in the BFBOF process involves the carbon reduction of iron ore (Fe 2 O 3) 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 ...
The same quenching process is also used by Tata Steel Visakhapatnam Steel Plant in India and by companies like Arcelor Mittal and Gerdau abroad. Process. The 100x100 or 110x110 billets of specified length from the continuous caster are transferred to the rolling mill by way of the Hot Charging conveyor.
The rolling mill has a power capacity of 5 MW per roll. The rolls rotate at a constant angular speed of 100 rev/min. The steel work material has the following flow curve at the rolling temperature: MPa. Assume the coefficient of friction µ= Is the available rolling mill adequate for the desired operation? m h i=75 mm h f = 60 mm
The hot metal is converted into steel through a steelmaking process called the LD process. Flat Products: The steel is cast into slabs, which are then rolled into hot rolled coils in the Hot Strip Mill Thin Slab Caster. Some of the hot rolled coils are further rolled into cold rolled and galvanisedcoils in the Cold Rolling Mill. Long Products:

The rolling process is shown in Fig. : Rolling is done both hot and cold. It is accomplishes in rolling mills. A rolling mill is a complex machine having two or more working rollers, supporting rollers, roll stands, drive motor, reducing gear, flywheel, coupling gear etc. Rollers may be plain or grooved depends upon the shape of rolled product.
The basic diagram of Rolling is shown below. Working Principle of Rolling Process: In Rolling operation, the metal strip or the material is to be placed in between two rollers such that material is compressed by the opposite forces of the rollers to make the material to a uniform thickness.
