Finishing Rolling Mill Process Explanation - Hani Tech

After all this processing of the rolling mill through the finishing mill machine, the steel has been rolled into a flat bar nearly 200 feet. However, in contrast to the roughing mills, the way of the finishing mills roll the transfer bar in tandem, meaning each bar would be rolled through all six stands at once.

Understanding Rolling Process in Long Product Rolling Mill ...

Understanding Rolling Process in Long Product Rolling Mill Steel rolling consists of passing the material, usually termed as rolling stock, between two rolls driven at the same peripheral speed in opposite directions (i.e. one clockwise and the second anti-clockwise) and so spaced that the distance between them is somewhat less than the thickness of the section entering them.

Finishing Rolling Mill Process Explanation - Hani Tech

Before the finish rolling mill processing, the head- and tail-ends of the transfer bar will be sheared for squaring them up, helping to ensure proper threading and tail-out. The final two-stage descaling operation is clean off the scale that has grown on the bar during roughing.

The surface hardening-hot core tempering process is a heat treatment process in which the rolled piece is quenched by the water-cooling device after it comes out of the finishing mill and then tempered by the residual heat of the core. The process improves the strength and toughness of steel by refining grains.

The process results in the formation of “Martensite” in the outer surface of the bar while the core remains austenitic. In. In the next step, the bar leaves the water quenching line and is exposed to air. The heat flux from the still-hot core reheats the outer surface within the structure.

Puddling (metallurgy) - Wikipedia

Puddling is a step in the manufacture of high-grade iron in a crucible or furnace. It was invented in Great Britain during the Industrial Revolution. The molten pig iron was stirred in a reverberatory furnace, in an oxidizing environment, resulting in wrought iron. It was one of the most important processes of making the first appreciable volumes of valuable and useful bar iron without the use of charcoal. Eventually, the
