Hot Rolling Mill Hydraulic Gap Control HGC thickness

For modern hot rolling mills the typical hydraulic circuit was designed to control the roll bending force during rolling process. The most common operating modes of the roll bending system were studied rolling, start and stop. The bending roll control system was designed in the form of functional blocks, connecting the actuators, sensors and sided subsystems of the rolling control.

The rolling mill is suitable for processing stainless steel, carbon steel and non-ferrous metal strips.

Vertical Roller Mill Hydraulic System

AbstractHydraulic bending roll system has become one of key equipments to control the exit strip shape in strip rolling mills. 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.In the rolling work, on the one hand, we must pay attention to controlling the running status of the rolling mill machine, and on the other hand, we must ensure that the hydraulic piping system is operating normally.Therefore, in order to meet the production requirements, the rolling mill piping subsystem mainly includes auxiliary hydraulic pressure, servo-hydraulic pressure, thin oil ...

Rolling of steel in Hot Strip Mill IspatGuru

Jul 01, 1994 The identification of a hydraulic system on a hot rolling mill is described. The rolling mill is in operation at The Danish Steelworks Ltd. in Frederiksvrk, Denmark. The hydraulic system is used for thickness control of the rolled plates. A non linear model for the system is derived and transformed to discrete time.Cold roll mill hydraulics Hot strip hydraulics Extrusion press hydraulics Forging Learn More DFE, Steel Mill Hydraulic System Element Breather Upgrade, Steel Mill Oscillator Hydraulic Filter Element Upgrade.

Strip Thickness Control of Cold Rolling Mill with Roll

The rolling mill with hydraulic system is widely used in the production of strip steel. For the problem of vertical vibration of the rolling mill, the effects of different equivalent damping coefficient, leakage coefficient, and proportional coefficient of the controller on the hydraulic screw down system of the rolling mill are studied, respectively.vertical roller mill hydraulic system component used for applying sufficient pressure to the grinding roller to crush materials. Controlled System. Pressure applied to the grinding roller being automatically controlled by the PLC/dCs enables the accurate control of grinding pressure and the highly efficient and stable operation of the mill ...

What Are the Characteristics of Rolling Mill Hydraulic

cooling system. Problems of this kind can never really be calculated but they have a detrimental effect on all rolling schedules including stresses in the roll. 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.

Modeling and Identification of Hydraulic System on Rolling

MSD is a hydraulic cylinder installed to mill housing window and press a roll chock against the opposite side with constant force. MSD eliminates gap between roll chocks and mill housing, keep rolls in proper position and stabilize rolls. Enables stable rolling at demanding rolling condition.

Nippon Yakins roughing mill handles plate rolling as well as rough bar rolling for strips with sophisticated hydraulic screw down system. The original physical model of rolling of the process computer enables optimum rolling pass schedule calculations for each product. Primary Specifications. Roughing Mill. four-high reverse mill.Reducing the roll gap increases the roll pressure to p3. Gage control in multiple rolling mills is achieved through measurement of strip thickness using x-ray gage and adjusting the strip tension using feedback control system. 1.8 Rolling defects Mill spring is a defect in which the rolled sheet is thicker than the required thickness because,

Looper and tension control in hot rolling mills A survey

The two backup-rolls reduce the bending deflection of the work-rolls. Additionally, the mills are equipped with devices for bending compensation like hydraulic bending systems and/or specifically shaped rolls (CVC-rolls). These measures shall ensure a plain roll gap and thus a uniform lateral thickness profile of the final product.

Worldwide, as the rolling speeds are increasing, greater emphasis is being placed on the aspects of safety while designing the mill equipment as well as during the finalization of the mill layouts. Providing high importance to safety is in the best interest of the designers, manufacturers and the users of the rolling mills.

Safety in Rolling Mills IspatGuru

Basically, hot-rolled means that the steel is heated in the furnace to a cherry-red temperature and then passed through a series of rolling mills to reduce it to the desired size. When cold-rolled steel is wanted, the hot-rolled steel is reduced only part of the way in gauge and then allowed to cool and then finally passed through a series of ...The hot rolled strip is later processed by a cold rolling mill, and to facilitate the threading operation, tapering is applied. Tapering is activated by a sensor which is located at a given distance from the mill stand on the rolling table at the entry side, and gives a signal when the strip end is in a given distance. This signal activates the tapering function, so the rolling thickness set-point is decreased following a
