The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.

Automatic Gauge Control, work roll bending in the finishing mill to give the strip a better profile and gauge Programmable Laminar Cooling for accurate temperature control of strip WIDTH RANGE - 650 mm–1270 mm & COIL THICKNESS RANGE - 1.6mm - 25 mm.

•The overall reduction is the summation of a series of small reductions by each pair of rolls. Therefore, the planetary mill can hot reduces a slab directly to strip in one pass through the mill. •The operation requires feed rolls to introduce the slab into the mill, and a pair of planishing rolls on the exit to improve the surface finish.

Hot Strip Mill Hot rolled coils ranging between 1.5mm to 23mm in thickness and widths of 750 to 1850mm through four furnaces, a 2-stand roughing mill, a 7-stand finishing mill and three coilers. Slabs are reheated to approximately 1250 ˚C depending on product, reduced in the roughing mill from 240mm to the required transfer bar thickness of ...

Take the value of roll radius as 250mm. Q10) Calculate the rolling load if steel sheet is hot rolled 30% from a 40mm thick slab using 900mm diameter roll. The slab is 760mm wide. Assume µ=0.30. The plain strain flow stress is 140MPa at entrance & 200MPa at exit from the roll gap due to the increasing velocity. Unit 5:- Drawing Q1)

Quenching – Once the hot rolled bars releases from finished mill it enters to the water spray system that is known as 'Thermex System'. The best quality tmt bars manufacturing process uses Thermex Technology that cool down the outer …

Hot Rolling Application. Hot rolling is used mainly to produce sheet metal or simple cross sections such as rail road bars from billets. Mechanical properties of the material in its final 'as-rolled' form are a function of: material chemistry, reheat temperature, rate of temperature decrease during deformation, rate of deformation, heat of ...

A simplified process flow diagram for a typical cane sugar production plant is shown in Figure 9.10.1.1-1. The cane is received at the mill and prepared for extraction of the juice. At the mill, the cane is mechanically unloaded, placed in a large pile, and, prior to milling, the cane is cleaned. The milling

The invention provides a hot-rolled strip steel width prediction method. The hot-rolled strip steel width prediction method comprises the following steps: an outlet thickness, an inlet thickness, an inlet width and an inlet temperature of a hot-rolled plate blank are determined according to technological procedure data in one pass of hot rolling; an inlet speed of the hot …

Cold rolled product is made from the hot-rolled product. When the hot-rolled product is cooled, then that is re-rolled in the room temperature. It is known as Cold Rolled Product. It is used to do to get more exact or perfect dimensions and to make the surface quality better. There are such Cold rolled products. Those are as follows: wire sheet ...

On the process of paper manufacturing process, in order to finally turn the pulp into paper, the pulp is fed or pumped into giant, automated papermaking machines. One common type is called the Fourdrinier machine, which was invented in England in 1807. Paper pulp is fed into the Fourdrinier machine on a moving belt of fine mesh screening.
