The pass line in a cold rolling mill passes through the center of the billet which is on the funace exit rollers and runs through each stand through the shear blades dividing the shear prior to the cooling bed. All of the guide equipment is aligned to the pass line.

Difference between Black mild steel and bright mild steel?
from what i can gather, which isn't alot:Cold Rolled Steel Strip is produced, as the term suggests by the further rolling of strip produced by the hot strip mills.Prior to cold rolling, the mill scale has to be removed, normally by the Pickling Process which uses mechanical manipulation (around small diameter rolls) and acid to dissolve the surface scale. The surface is then washed to remove the acid and a light oil added to prevent rusting.Mild steel sheet is manufactured generally in two grades, cold rolled and hot rolled.Hot rolled mild steel sheet is the initial product produced by the steel mill as a downstream process prior to further processing such as cold rolling.Hot rolled mild steel sheet has a mill scale which is usually black in colour. Hence the common name Black Mild Steel Sheet. Black mild steel sheet is commonly used in fabrication shops, it is more economical than cold rolled mild steel sheet.Black mild steel sheet will usually require more preparation work prior to any finishing system being applied.Cold rolling is done to:Reduce the thicknessImprove the surface finishImprove the thickness tolerancesTo offer a range of "tempers"As a preparation for surface coating

What is the advantage of tandem rolling?
A tandem mill is a special type of modern rolling mill where rolling is done in one pass. In a traditional rolling mill rolling is done in several passes, but in tandem mill there are several stands (>=2 stands) and reductions take place successively. The number of stands ranges from 2 to 18. Tandem mills can be either of hot or cold rolling mill types.Advantages:Highest production rates,Optimized yield,Reduced roll consumption,Flexible productionTight tolerances for strip thickness, shape, and high surface quality,Low costs for operation, maintenance, and minimum down times.
When was Little Matlock Rolling Mill created?
Little Matlock Rolling Mill was created in 1882.
What does 4-Hi mill mean?
4-Hi is a kind of rolling mill configuration in metalworking. It means the mill has four rolls, two small and two large.
Which universal rolling mill is of good quality?
Universal rolling mill - Yushun factory direct supply The profile mill consists of a pair of horizontal rolls and a pair of vertical rolls and the axis of the rolls is in the same vertical plane. Vertical rolls can be active rolls, but also passive rolls, but to ensure that the roll surface line speed and horizontal rolls in line. In the universal mill (called the main machine) after or before often set up a two-roller horizontal mill, as an auxiliary forming frame (i.e., rolling edge end machine), the main and auxiliary machines are reversible mills, in the rolling process to form a continuous rolling.
Can quarter buckling be corrected at cold rolling mill?
Yes it can be corrected by given small elongation 0.2 to 0.5% by TLL
What is the process called when metals are rolled into thin sheets like aluminum foil?
The process of rolling metals into sheets is called (no surprise) rolling. The metal is passed through a rolling mill and is reduced in size in steps. The metal might be hot rolled or cold rolled, and the choice of process depends on the metal and on what the finished product needs to be like. In the case of aluminum foil, a block of aluminum is first hot rolled, and the metal is passed through the rolling mill a number of times until it is thin enough to be rolled and moved to a cold rolling mill. In the cold rolling mill, it goes through a number of roller sets until the desired thickness is achieved.
