Republic of Lithuania steel mill cylinder

(Republic of Lithuania steel mill cylinder,produced by Hengyu Group)

steel mill cylinder are widely used in Republic of Lithuania,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed steel mill cylinder for customers from Republic of Lithuania.

Introduction to steel mill cylinder:

If the piston rod and steel mill cylinder are stuck or the steel mill cylinder is blocked, at this time, no matter how to operate, the steel mill cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the steel mill cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

steel mill cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the steel mill cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

How to repair the steel mill cylinder body when it is damaged: When the steel mill cylinder has trace deformation and shallow tensile marks, the steel mill cylinder is repaired by strong honing process. The heavy honing process can repair steel mill cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the steel mill cylinder can meet the technical requirements.

The repair method of steel mill cylinder wear: 1. Metal repair material is applied to the scratched surface; The first layer should be thin, uniform and fully covered with the scratched surface to ensure the best adhesion between the material and the metal surface, and then apply the material to the entire repair site and press repeatedly to ensure that the material is filled and reaches the required thickness, so that it is slightly higher than the surface of the guide rail; 2, the material at 24℃ to fully achieve the performance of 24 hours, in order to save time, can be through the tungsten halogen lamp to increase the temperature, the temperature rises 11℃, the curing time will be reduced by half, the best curing temperature 70℃; 3. After the material is cured, use a fine grinding stone or a scraper to repair and smooth the material higher than the surface of the guide rail, and the construction is completed.

Answers to some questions about steel mill cylinder:

What is the HS code of the hydraulic cylinder?
HS code of hydraulic cylinder; 8412210000 8412210000 Linear hydraulic power unit (hydraulic cylinder) 0.12000 0.35000 0.00000 0.17000 0.00000

How to calculate multistage cylinder volume?
When the multi-stage cylinder is extended, the largest cylinder is extended first, and when the largest cylinder stroke is completed, the second largest cylinder is extended again, the second largest cylinder stroke is completed, the third largest cylinder is extended again... Therefore, the cylinder extension length is less than the stroke of the largest cylinder, and the volume is the extension length times the inner hole area of the largest cylinder. The cylinder extension length is greater than the maximum cylinder stroke and less than (the largest cylinder stroke + the second largest cylinder stroke), and the volume is the largest cylinder stroke times the internal hole area of the largest cylinder + (the extension length - the largest cylinder stroke) times the second largest cylinder.
