Large-scale servo hydraulic cylinders are suitable for steel rolling equipment in steel plants, such as AGC (Hydraulic Automatic Gauge Control), AWC (Automatic Width Control), APC (Automatic PressureControl), and HAGC (Hydraulic Automatic Gap Control) systems. These cylinders can have a maximum diameter of up to Ø1050mm and a stroke length of up to 135mm. They can be customized or modified based on specific requirements or original designs to meet the desired specifications.

Automatic gauge control (AGC) is a system that controls rolling equipment to ensure uniform thickness, width, and surface quality of steel. AGC systems consist of multiple sensors, controllers, and actuators. Sensors measure the thickness, width, and surface quality of steel. Controllers calculate the required rolling force based on the sensor measurements. Actuators transmit the controller's commands to the rolling mill to adjust the rolling force.
AGC systems have the following characteristics:
•High precision: AGC systems can control the thickness, width, and surface quality of steel with very high precision.
•High stability: AGC systems can maintain the stability of the thickness, width, and surface quality of steel even in the presence of variables during the production process.
•High efficiency: AGC systems can improve the production efficiency of steel and reduce steel waste.
Hydraulic cylinders used in AGC systems need to have the following characteristics:
•High torque: Hydraulic cylinders need to have sufficient torque to provide the required rolling force.
•High precision: Hydraulic cylinders need to have high precision to ensure the accuracy of the rolling force.
•High reliability: Hydraulic cylinders need to be highly reliable to ensure normal production.

AGC systems are an important part of steel rolling equipment. They can improve the quality, production efficiency, and production costs of steel. Servo hydraulic cylinders are the core of AGC systems. Hopetech has assisted many steel mills, such as China Steel Corporation and Dragon Steel Corporation , in manufacturing or repairing AGC servo hydraulic cylinders. Hopetech 's products are of high quality and meet the requirements of AGC systems for high torque, high precision, and high reliability.
