Large bag lifting cylinder

The main component of the ladle turntable has been widely used in the pouring engineering of the converter and continuous casting machine in the steelmaking system. Generally, it is a large single acting piston hydraulic cylinder, and there are also double acting piston hydraulic cylinders equipped with balance valve blocks to control the loss of control caused by the load of the steel ladle and prevent the locking function of pipeline explosion; Plunger diameter is approximately 500mm-900mm

Mold width adjustment cylinder

The mold width adjustment hydraulic cylinder is an online width adjustment (narrowing) device for slab continuous casting mold, consisting of a hydraulic cylinder body and a hydraulic valve block device. The valve block at the bottom of the cylinder is equipped with servo valves, hydraulic control one-way valves, overflow valves, and displacement sensors. It has outstanding advantages, reasonable structure, high reliability, and can greatly improve production efficiency, reduce labor intensity. It is an ideal servo hydraulic cylinder for narrow edge width adjustment of crystallizers.

AGC hydraulic cylinder

One of the most important core execution components in the AGC hydraulic cylinder strip thickness automatic control (AGC) system. During the rolling process, the position of the AGC cylinder (and the working roll gap of the rolling mill) needs to be accurately and effectively controlled in real-time by correction commands, so that the target thickness, same plate difference, and different plate difference of the product can meet the indicator requirements. The AGC cylinder requires high control accuracy, fast response, and low friction. Basic requirements: Cleanliness: NAS5 level Minimum starting pressure: ≤ 0.05MPa Bandwidth (-3db): ≥ 10Hz Step response: ≤ 50ms@0.1mm Or ≤ 25ms@0.05mm Loading hysteresis: ≤ 0.5% Fn

AWC hydraulic cylinder

The main executive component in the automatic width control (AWC) system of the vertical roller of the roughing mill. According to the parameters measured by the width gauge and pressure sensor, adjust the width of the vertical roller in a timely and dynamic manner to reduce the width deviation of the rolled piece over the entire length. It is a high-end servo cylinder with dynamic characteristics such as fast response, high speed, and low friction. Produced specifications: 580/320 750, 570/340 750, 450/300 815, 510/310 725, 420/320 660, etc
