(Poland steel mill cylinder,produced by Hengyu Hydraulic Cylinder Factory）

steel mill cylinder are widely used in Poland，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed steel mill cylinder for customers from Poland.

Introduction to steel mill cylinder:

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular steel mill cylinder action. Troubleshooting method: Replace the rubber hose.

steel mill cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

In the case of serious wear on the inner surface of the steel mill cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the steel mill cylinder manufacturing process for replacement. The steel mill cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

When the piston speed of the steel mill cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the steel mill cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

Answers to some questions about steel mill cylinder:

How is the hydraulic cylinder tempered?
The purpose of the tempering treatment is to make the piston rod have comprehensive mechanical properties of strength, hardness, plasticity and toughness, and the internal structure is uniform and fine tempered sorbite, so as to prepare the organization for subsequent surface quenching. The length of the long cylinder piston rod is 3800-4200, and the diameter is Φ90-Φ110mm, so its heating equipment uses a 150KW well resistance furnace or 600KW suspension continuous resistance heating furnace, and the temperature is controlled by two areas. Heat treatment process parameters: in the shaft furnace, a furnace is suspended with 4 pieces, the quenching heating temperature is 830±10℃, and after holding heat for 160min, it is divided into two times for quenching, and two pieces are quenched each time, and the circulating cooling water is used for cooling.

Can pneumatic cylinder be used as hydraulic cylinder?
The pneumatic cylinder can only be used for pressure below 1MPA, and if it is used for hydraulic, the pressure should be under 1MPA, which may not meet the strength requirements. And the seals should use fluorine rubber to avoid corrosion. But pneumatic cylinder used as hydraulic cylinder is not whimsical, in fact, there is such a use. The pneumatic system has a natural defect, that is, the speed is unstable, especially in the case of low speed. The hydraulic pressure is very stable, if you do not want to buy a set of hydraulic system, while the strength of the cylinder is not large, you can use compressed air to push the hydraulic oil, with hydraulic oil to drive the cylinder, The force is the same as compressed air, but very smooth.
