As a result our engineers have developed and algorithms that minimize manual operator inputs to ensure reliable rolling. Cascade Control. Cascade control uses the reduction concept (R-Factor) to calculate the mill cascade speed reference. This parameter, directly related to rolling fundamentals, simplifies the setup and operator control.

Rolling Offset Calculation. Formula. In the diagram above, the relationship between the travel length and the offsets is as follows: X = SquareRoot(Square of V + Square of H) Travel T = X / (cos (90-Fitting Angle)) Run R = SquareRoot ( Square of Travel T – Square of X)

The load analysis of rolling machine can be reference data for designing parts of plate rolls. The calculation of the main driven power of the plate roll bending machine is the key reference data for choosing the main motor. The motor power should be chosen properly.

Stockpile Calculator . The "Smalis Stockpile Calculator" is simple to use, requires no research on materials and yet, provides the pertinent information regarding all aspects of the stockpile. Simply enter the material to be conveyed and the length of the conveyor that is being considered.

Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8-hour shift, allowing to calculate corresponding to circulating …

Multi-pass Hot Rolling of Steels Multi-pass hot rolling is a general practice in the production of plates. An illustration of a plate mill, Fig. 1, is shown below to demonstrate how a series of processes are carried out to produce plates from steel slabs.

Jun 01, 1954· The Calculation of Roll Force and Torque in Hot Rolling Mills R. B. Sims, B.Sc. Proceedings of the Institution of Mechanical Engineers 1954 168 : 1, 191-200

The calculation of rolling force. When manufacturing sheet products it's important to understand the rolling force. This is because you need it to set the appropriate roll gap on the mill, accounting for the stretch of the stand. The prediction of rolling force can be challenging due to the large number of inter-connected process variables ...

Rolling Offset Calculation. Formula. In the diagram above, the relationship between the travel length and the offsets is as follows: X = SquareRoot(Square of V + Square of H) Travel T = X / (cos (90-Fitting Angle)) Run R = SquareRoot ( Square of Travel T – Square of X)

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 of the order of 1,000 tons is generated during rolling, so that mill deformation of …

Bearing Rating Life Calculation "Rating life" is the bearing life calculated for 90% reliability. This is the amount of time that a group of apparently identical bearings will complete or exceed before the formation of a fatigue spall. The basic formula for calculating bearing L 10 rating life is: where: C = Dynamic Capacity (dN or Lbs)

Geleji's relations indicate the opposite trend. Roberts combined the data obtained from an experimental 2-high mill, an 84 inch hot strip mill and a 132 inch hot strip mill, all rolling well descaled strips, and used a simple mathematical model to calculate the frictional coefficient. Linear regression analysis then led to the relation:

Following are the results of the calculation of the roll load for various passes of the material through the rolling mill on the basis of the output voltage obtained in the strain indicator circuit.

Thread Rolling Figure 13.16 (a) Features of a machined or rolled thread. (b) Grain flow in machined and rolled threads. Unlike machining, which cuts through the grains of the metal, the rolling of threads causes improved strength, because of cold working and favorable grain flow. Figure 13.15 Thread-rolling processes: (a) and (c) reciprocating
