Four-high rolling mill A four high rolling mill is used for reducing material to minute thicknesses. Through the use of backup rolls, the issues of roll deflection can be avoided and smaller work rolls can be used. The reduction in work roll diameter reduces overall separating force required for reductions; reduces the overall energy needed for

Depending on the product mix, a single-stand cold rolling mill can deliver rolling capacities of 100,000 to 400,000 t/a. Rolling schedules can be carried out with an even or odd number of passes to maximize mill availability and performance.

With a roller mill you should still use the feeler gauge set to make sure the gap is uniform from end to end. If you have no test sieves, you need to adjust the mill by carefully evaluating one-cup samples. Start with the stock setting for a roller mill, or set screw two turns out for a corn mill. Keep tightening the gap until you no longer find any uncrushed kernels. If you are able to assay

Draft is sometimes expressed as a fraction of the starting stock thickness, called the reduction 5.2 Where r = reduction. When a series of rolling operations are used, reduction is taken as the sum of the drafts divided by the original thickness. In addition to (Cross sectional area > 40x40 mm2). area > 230 cm2). (Cross

To minimize the roll diameter a four-high or cluster mill is used. A small roll diameter is advantageous because less roll is in contact with the material, which results in a lower force and power requirement. The problem with a small roll is a reduction of stiffness, which is overcome using backup rolls. These backup rolls are larger and contact the back side of the smaller rolls. A four-high

As regards "abnormal" rolling conditions - which are more or less very "normal" for rolling mills - roll damage often occurs with consequences for the mill and the rolled product. Evidently the reasons of roll failure have to be discussed and determined (or vice versa) to reduce the risk of repeated roll damage and its consequences, or indeed to eliminate the risk completely. These
