Metallurgy Machinery Cylinders

Types

• Single - acting hydraulic cylinders:

• They use hydraulic pressure to move in one direction and rely on a spring or external force like gravity to return the piston. In metallurgy, they are often used in simple metal stamping operations where force is only required in one direction.

• Double - acting hydraulic cylinders: Hydraulic pressure is used to move the piston in both directions, enabling force application in both the extending and retracting strokes. They are widely used in the metallurgical industry, such as in metal rolling mills to control the gap between rolls.

• Telescopic hydraulic cylinders: Composed of a series of nested cylinders, they can provide a long stroke in a relatively compact space. In the metallurgy industry, they are used in metal lifting equipment and other occasions where a large stroke is required but space is limited.

Characteristics

• High - strength materials: Since metallurgical machinery often operates in high - temperature, high - pressure, and heavy - load environments, cylinders usually use high - strength steel materials. For example, the cylinder barrel is generally made of seamless steel pipes, and the end cover and piston are made of cast iron or carbon steel.

• Good sealing performance: To ensure the normal operation of the cylinder and prevent fluid leakage, high - performance sealing materials and structures are required. Sealing technology needs to adapt to different working conditions such as high temperature and dust.

• Precision manufacturing: In order to meet the process requirements of metallurgical production, such as precise control of the thickness of metal sheets, cylinders need to have high - precision manufacturing accuracy. For example, some cylinders are equipped with internal measuring systems to achieve precise positioning.

Standards

Applications

• Furnace tilting systems: In electric arc furnaces and blast furnaces, cylinders are used to drive the furnace tilting system to enable precise tilting for pouring molten steel.

• Continuous casting mold oscillation systems: Cylinders drive the mold oscillation in continuous casting plants to prevent molten steel from sticking to the mold walls and ensure the surface quality of the steel.

• Rolling mills: Cylinders are used to control the gap between the rolls to accurately adjust the thickness of the metal sheet or strip.
