Oils, soap emulsions, fatty acids are used as lubricants during hot rolling non-ferrous metals. Mineral oils, paraffin, fatty acids are used for cold rolling. Normally, foe ferrous alloys no lubricant is used. 1.7 Rolling mill control: Production of continuous sheets and strips is one of the attractive features of modern rolling mills.

The state space model formulation is used in the minimization of the strip thickness variations in a hot rolling mill to lead to a less output thickness variations with the real industrial data. In this paper, a real application of opti- mal control of a hot rolling mill is presented. It is used the state space model formulation in the minimization of the strip …

A Hille-100 rolling mill with rolls of 225 mm diameter and 254 mm length, driven by a variable speed DC motor of 75 horse power, was used. The maximum rolling force, torque and speed are 1500kN, 13kN-m and 70 rpm respectively. The sensor roll nitrided surface hardness is 65 to 70 HRC.
Area: Production Process Engineering 344 exits the furnace by means of an internal roller conveyor. When the product exits the furnace it is sent via a roller conveyor to the rolling-mill train formed by 18 continuous lamination jigs which reduce the diameter of the material for market consumption (after it has passed through

A Simulink and mathematical models have been proposed in this study in order to control the thickness in a rolling mill process. The simulation results show that the thickness oscillation can be manipulated with high accuracy by using NARMA-L2, since it can remove the non-linearity of servo system and other disturbances complexities. The …
Therefore, a two-step approach combining heuristic-mathematical programming methods has been developed. The steps are: 1. Build hot rolling programs 2. Sequence the built rolling programs The programs built in step 1 should be as long as possible and contain as many orders as possible meeting production and quality rules.

A majority of modern rolling mills to eliminate the roll bending value during the operation, are equipped with a work roll bending system (WRBS) [4]. WRBS has a hydraulic cylinders at the roll edges, which create a compensation force. The value of this force must convert the bending curve into constant roll-gap.
Rolling mills represent an extremely demanding application for both bearings and rolls, which must perform under high operating temperatures, loads and speeds. During the …
