Rolling is most often, (particularly in the case of the conversion of an ingot or continuous casting), performed hot. At a rolling mill, blooms and slabs are further rolled down to intermediate parts such as plate, sheet, strip, coil, billets, bars and rods. Many of these products will be the starting material for subsequent manufacturing ...
NOTE: Hot-rolling and cold-rolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hot-rolled or cold-rolled. HOT-ROLLED STEEL. Hot-rolling refers to a mill process in …

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.
This spreader beam transports large paper rolls in a major paper mill. Motorized rotating spreader beams handle large rolls by engaging the core shaft with J-hooks. The design features double beam construction with powered rotation to turn the roll in the horizontal plane for positioning, another example of automatic material handling.
The rolls used in Rolling Mill included different material and size, such as high alloy forged rolls, muti-casted iron rolls etc. The sizes are fromΦ360 mm toΦ1960mm, hardness layer in difference depth by heat-treatment. New rolls and used rolls are inspected by different NDT methods to make sure its in good condition for next rolling turn.

Reheating furnace for steel rolling mill line is a device (an industrial furnace) that heats a material or a workpiece (generally a metal) to rolling forging temperature in the metallurgical industry.. Structure and composition. According to the distribution of furnace temperature, the furnace is divided into preheating section, heating section and heating section along the length …
The beam section consists of web and two flanges. The junction between the flange and the web is known as fillet. These hot rolled steel beam sections have sloping flanges. The outer and inner faces are inclined to each other and they intersect at an angle varying from 1½ to 8˚ depending on the section and rolling mill practice.

2) Mill Spring- Mill spring is defect when the thickness of the rolling sheet is greater than the required thickness. Elastic deformation of roll mill equipment or the rolls lead to mill spring. Normally elastic constant for mills may range from 1 to 4 GNm-1. Remedies: Use of a stiffer material for making rolls can solve this problem.
enough to cause bending of the material in the entry or exit side guards. The material folded when passing through the work roll causes an excessive differential roll force in the mill stand and may rupture. The results are scrapping, line stoppages, damage to work rolls and damage to other stand mill components, as
