Installation method of metallurgical hydraulic cylinder

1. Earring installation (pivot mounting)

   Structural features: The Telescopic Hydraulic Cylinder is equipped with earrings (pin holes) at both ends or one end, which are connected to the equipment through a pin shaft and allow for a certain degree of deflection.

   Applicable scenarios:

   • Mechanisms that require swinging or angle adjustment (such as continuous casting machine sector adjustment, blast furnace bell opening and closing).
   • In situations where space is limited or multiple degrees of freedom are required for movement.

   Advantages: Flexible installation, adaptable to dynamic load changes of equipment, and reduces stress concentration.

2. Flange Mounting

   Structural features: The Double Acting Hydraulic Cylinder barrel or cylinder head/bottom is equipped with flange plates, which are fixed to the equipment bracket or base by bolts.

   Applicable scenarios:

   • High voltage, heavy-duty fixed workstations (such as rolling mill pressing devices, steelmaking converter tilting mechanisms).
   • A straight line push-pull scene that requires a rigid connection.

   Advantages: Stable structure, strong load-bearing capacity, suitable for high-precision positioning.

3. Foot Mounting

   Structural features: The bottom of the cylinder is welded or cast with feet, which are fixed to the equipment base or foundation with bolts.

   Applicable scenarios:

   • Large metallurgical equipment (such as blast furnace opening machine, iron ladle tilting mechanism).
   • Long stroke hydraulic cylinders that require load dispersion.

   Advantages: Simple installation, easy maintenance, suitable for fixed installation in horizontal or vertical directions.

4. Trunnion Mounting

   Structural features: The middle of the cylinder or the end of the piston rod is equipped with a hinge shaft (ear shaft), which is fixed to the equipment support and allows for small angle swinging.

   Applicable scenarios:

   • Continuous casting machine crystallizer vibration device, steel rolling mill guide adjustment.
   • In situations where local oscillation is required but the load is large.

   Advantages: Reduce lateral force, improve sealing life, and adapt to dynamic loads.

5. Pin Eye Mounting

   Structural features: The end of the piston rod is processed into a shaft pin structure, which is directly inserted into the equipment pin hole and fixed with an open pin or snap spring.

   Applicable scenarios:

   • Equipment that requires quick disassembly and assembly (such as electric furnace cover lifting, ladle sliding water nozzle control).
   • A compact workspace that requires frequent replacement.

   Advantages: Easy disassembly and assembly, compact structure, suitable for high-frequency movements.

6. Hanging Mounting

   Structural features: The top of the oil cylinder is suspended on the equipment frame through lifting rings or ears, and the piston rod drives the load downwards.

   Applicable scenarios:

   • Vertical lifting equipment (such as steel coil transport carts, heating furnace door lifting).
   • In situations where floor space needs to be saved.

   Advantages: Save installation space and reduce the impact of ground vibrations.

7. Welded Mounting

   Structural features: The oil cylinder barrel or installation flange is directly welded to the equipment steel structure to form a permanent fixation.

   Applicable scenarios:

   • Special customized equipment (such as metallurgical hydraulic stations, heavy-duty shearing machines).
   • In situations where high-strength integrated connections are required.

   Advantages: High structural rigidity and strong impact resistance, but requires cutting and dismantling for maintenance.

8. Guide Rail Mounting

   Structural features: The oil cylinder is installed in combination with linear guide rails and sliders, and the direction of motion is constrained by the guide rails.

   Applicable scenarios:

   • High precision positioning requirements (such as cold rolling mill roll gap adjustment, laser cutting machine mobile platform).
   • In situations where lateral forces need to be resisted.

   Advantages: Improve the straightness of motion, extend the life of oil cylinders and seals.

Installation precautions

• Load centering: Ensure that the axis of the oil cylinder is aligned with the direction of the load to avoid lateral force causing seal wear or piston rod bending.
• Sealing protection: In metallurgical environments with high levels of dust, it is necessary to install dust covers or use high-temperature corrosion-resistant sealing materials (such as fluororubber).
• High temperature protection: When approaching a heat source, the cylinder needs to be equipped with a thermal insulation layer (such as ceramic coating or cooling water jacket).
• Lubrication maintenance: Regularly check the lubrication status of the pin shaft and hinge points to prevent jamming or corrosion.
• Foundation reinforcement: The installation base should have sufficient strength to avoid bolt loosening caused by vibration or impact.

Typical application examples in the metallurgical industry

• Continuous casting machine: earring installation (crystallizer vibration), flange installation (billet pressing machine).
• Rolling mill: Bottom installation (AGC Hydraulic Cylinder), articulated installation (guide adjustment).
• Blast furnace: shaft pin installation (bell opening and closing), suspended installation (furnace top distributor).

According to specific working conditions (such as temperature, load, and motion trajectory), flexible design can be combined with the above installation methods. If necessary, contact the manufacturer to customize a dedicated installation structure (such as explosion-proof or corrosion-resistant).
