Understanding Rolling Process in Long Product Rolling

If the mill rolls 800,000 tons per year, it runs at an average production rate of 114.16 tons/hour. If the utilization can be improved by 1 %, the available rolling hours is 365 x 24 x 0.81 = 7096.6, creating 87.6 extra rolling hours. At 114.16 tons/hour that is an additional 10,000 tons can be rolled. Excess billet gap can be an unaccounted for loss of rolling time. If a mill rolls 800,000,What are main Types of Rolling mill? - mech4study,Every rolling mill consist minimum two rolls. These numbers can extend according to the process requirement.

Basics of Rolling and Rolling Mills – IspatGuru

Fig 4 Roll configurations in rolling mills. Two-high mill roll configuration – This is the most commonly used rolling mill configuration. In this configuration, there are two horizontally mounted rolls. The rolling mill motor drives either both rolls (top and bottom) or only one roll (normally the bottom roll) with the top roll rotating due to the friction between the roll and the work piece.Hot and Cold Rolled Steel Explained - MST Steel Corp,These backup rolls are larger and contact the back side of the smaller rolls. A four-high mill has four rolls, two small and two large. A cluster mill has more than 4 rolls, usually in three tiers. These types of mills are commonly used to hot roll wide plates, most cold rolling applications, and to roll foils. [9] Historically mills were classified by the product produced: [29] Blooming,3B(2) Deformation of Rolling Mill,The ratio of the rolling force to the amount of vertical deformation of the whole rolling mill, including the deformation of the roll, screw-down device, and housing, is called the mill modulus. The mill modulus is 500-1,000 ton/mm for plate rolling mills and 400-600 ton/mm for cold rolling mills. The larger the diameter of the back-up rolls, the higher the mill modulus. A rolling force

THE MECHANICS OF TENSION CONTROL

The web must be “in traction” with all machine idler rolls and driven rolls to ensure proper web handling and control. • The web handling principal states a web will seek to align itself perpendicular to an idler or driven roll. This web handling principal is applied to route webs through processes with parallel idler rolls and driven rolls. It is applied when web guides areUnderstanding Rolling Process in Long Product Rolling,Rolls are the tools of the rolling mill and are the costliest consumable in a rolling mill. The way the rolls are used to execute their duty of deforming steel is in many cases largely determined by the roll pass design. The purpose of the roll pass design is (i) production of correct profile within tolerance limits with good surface finish (free from surface defects), (ii) maximum productivityBasics of Rolling and Rolling Mills – IspatGuru,Fig 4 Roll configurations in rolling mills.

Hot Strip Mill - an overview | ScienceDirect Topics

Work rolls in hot strip mills wear due to friction between the roll surface and hot strip. (Back-up rolls wear as well, but under pressure with elastic deformation, the friction is much less, except for the high work roll roughness in the last stand of a sheet rolling tandem cold mill). The wear is uneven from one end of the barrel to the other,What is the paper converting industry?,The new resized rolls are now ready to be used in the various printing processes required to make our everyday items like books, boxes, bags and more.
