Hydraulic automatic gauge control (AGC) system has become one of key equipments to control the exit strip thickness in strip rolling mills. The hydraulic AGC system of a hot rolling mill was ...
· The role of a hot strip mill process is to roll the slabs produced in a continuous casting process and produce strips of thickness –20 ... by changing the roll gap using hydraulic screw down system. However, while this hydraulic gap control system enables a faster response for thickness control, it often creates a disturbance to the tension control system because of the mass flow change ...

· Considering the two kinds of nonlinear constraints of rolling mill hydraulic cylinder, spring force and friction force, the vibration model of rolling mill system is established. The amplitude frequency response equations are obtained by using the average method. Comparing the time history curves of vertical vibration displacement of rolling mill system under the nonlinear spring force and ...

HYDRAULIC CIRCUIT DESIGN AND ANALYSIS A Hydraulic circuit is a group of components such as pumps, actuators, and control valves so arranged that they will perform a useful task. When analyzing or designing a hydraulic circuit, the following three important considerations must be taken into account: 1. Safety of operation 2. Performance of desired function 3. Efficiency of operation It is very ...
The hydraulic bending roll system of a hot rolling mill was researched and analyzed, and its mathematics models were founded in whole based on the action principle of some representative hydraulic components. At last, the hydraulic bending roll system was simulated with MATLAB by computer. It is obvious that the simulation curves are similar to the real response curves very much. .

These backup rolls are larger and contact the back side of the smaller rolls. A fourhigh 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 appliions, and to roll foils.
· Rectifier roll or evenor roll. This roll are used in paper machine headbox to control both the even out flow irregularities and to create turbulence to keep the fiber dispersed up to the slice opening. It is also known as hollow perforated roll or holey roll. Normally the hole diameter is about 2 to 4 cm. Paper machine headbox slice
