tilting furnace hydraulic cylinder are widely used in Portugal，because of no need for deceleration device，long service life，smooth movement.So our company has designed tilting furnace hydraulic cylinder for customers from Portugal.

Introduction to tilting furnace hydraulic cylinder:

How to repair the tilting furnace hydraulic cylinder body when it is damaged: When the tilting furnace hydraulic cylinder has trace deformation and shallow tensile marks, the tilting furnace hydraulic cylinder is repaired by strong honing process. The heavy honing process can repair tilting furnace hydraulic 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 tilting furnace hydraulic cylinder can meet the technical requirements.

The machining accuracy of the tilting furnace hydraulic cylinder depends on the level of equipment, production technology and testing means. tilting furnace hydraulic cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

The piston rod of the tilting furnace hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

tilting furnace hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching tilting furnace hydraulic cylinder block - fine boring tilting furnace hydraulic cylinder block - grinding tilting furnace hydraulic cylinder block. The rolling method is: broaching tilting furnace hydraulic cylinder block - fine boring tilting furnace hydraulic cylinder block - rolling tilting furnace hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the tilting furnace hydraulic cylinder block is about 1-2 days, rolling 1 meter of the tilting furnace hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the tilting furnace hydraulic cylinder increases by 25%. If the tilting furnace hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality tilting furnace hydraulic cylinders, you must take the rolling production process. After the tilting furnace hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

Answers to some questions about tilting furnace hydraulic cylinder:

What parameters do I need to provide when purchasing hydraulic cylinders?
The main technical parameters of the hydraulic cylinder: 1. Cylinder diameter; Cylinder diameter, inner diameter size; 2. Piston rod diameter; 3. Cylinder stroke; 4. Cylinder pressure; The working pressure of the cylinder is often calculated using the test pressure, which is less than 16MPa multiplied by 1.5 and higher than 16 multiplied by 1.255. Import and export diameter and thread parameters; 6. Whether there is buffer; According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7. Installation method of oil cylinder, etc.

How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.
