Rolling process in Steel rolling plant

Rolling of steel is one of the most important manufacturing processes for steel. Steel rolling is the process of plastically deforming steel by passing it between rolls. Rolling is defined as the reduction of the cross sectional area of the steel piece being rolled, or the general shaping of the steel products, through the use of the rotating rolls.

The initial rolling of steel is done in a hot rolling mill where blooms and slabs are rolled down to various rolled products such as plate, sheet, strip, coil, billet, structures, rails, bars and rods. Steel rolling can produce a wide range of products. The width of a rolled product can vary from a few millimeters to several meters while the thickness can vary from 0.1 mm to more than 200 mm. The rolled section can be square, rectangular, round or shaped sections.

Rolling of steel is done not only to achieve the desired cross section but also to get the desired properties of steel. Rolling of steels imparts strength and favourable grain orientation. Further heat treatment processes incorporated during controlled rolling helps in modification of steel microstructure to give the steel desired properties.

Mould in Continuous casting

The mould is the key part of the Continuous Casting Machine. The mould quality will directly influence the quality and production of steel billets.

The mould provides the required strand geometry and primary heat removal during the initial development of the strand shell. Primary cooling water passed along the gap between copper tube and water jacket provides the efficient convective heat transfer. 

Main Components:
Copper tube
Water jacket
Flanges at top and bottom
Spray ring

 Casting Mould for Steel Making

Tundish for Continuous casting machine

Continuous casting is a method of producing an infinite solid strand from liquid steel by continuously solidifying it as it moves through a CC machine.

To transfer liquid steel from a teeming ladle to the continuous casting machine mould, an intermediate vessel, called a tundish, is used. 

The continuous casting tundish serves as a buffer and links the discontinuous process of the secondary steel making in the ladle with the continuous casting process in the mould. It acts as a reservoir during the ladle change periods and continues to supply liquid steel to the mould when incoming liquid steel is stopped, making sequential casting by a number of ladles possible.

Many steel plant operators have studied their tundishes in order to maximize the benefits of the residence time available for the floatation and assimilation of reaction products from the liquid steel into the slag phase. These can be products of deoxidation, reoxidation, precipitation, emulsification and/or entrainment of refractory components into the liquid steel, and thus encompass both indigenous and exogenous inclusions. Based on a sound choice of tundish design, the operation of a tundish needs to be geared to the following.

• To promote inclusion floatation by maximizing residence time

• To ensure inclusion assimilation by a captive and noncorrosive slag

• To reduce thermal and chemical losses from the liquid steel

• To minimize short circuiting and dead zones

• To offer the operator an optimal design for quality and yield.
