At Tianjin Uranus Hydraulic Machinery Co., Ltd., we specialize in custom-engineered metallurgical hydraulic cylinders that are precisely tailored to the unique equipment and process requirements of the metals industry. As a “national small giant” enterprise, we work closely with mill operators and original equipment manufacturers to develop cylinders that optimize performance for specific applications, such as hot strip mills, plate levelers, and shears. Our custom design process starts with a detailed assessment of the operating environment, including the type of contamination, temperature ranges, and dynamic loads. Based on this, we select materials and seal configurations that maximize service life. For example, for cylinders used in descaling units, we design with special rod coatings to resist the erosive effect of high-pressure water. For cylinders in caster sections, we focus on seal longevity and easy maintenance, often incorporating split-flange connections for faster disassembly. We also provide cylinders with integrated position feedback, such as magnetostrictive sensors housed in a protective tube, allowing for precise control of critical processes like mold level control. Our manufacturing facility is equipped to produce cylinders with long strokes and large bores, meeting the demands of the largest mill equipment. We maintain a comprehensive inventory of materials and components to support rapid customization and delivery. For customers looking to improve the reliability and maintainability of their mill equipment, our custom metallurgical cylinders offer a tailored solution. To discuss your specific needs and how our engineering expertise can benefit your operation, please contact us.

Frequently Asked Questions

What is the advantage of using your servo hydraulic cylinders in testing applications?

Our servo hydraulic cylinders are ideal for testing applications because they deliver precise, repeatable force and position control with low friction and high stiffness. We offer cylinders with integrated feedback sensors such as LVDTs or magnetostrictive probes, enabling closed-loop control for accurate test results. For high-frequency applications, we provide cylinders with hydrostatic bearings that offer zero friction and infinite wear life. Our cylinders are designed for the dynamic demands of materials testing, fatigue testing, and structural testing, ensuring reliable performance over millions of cycles.
Yes, we design and manufacture hydraulic systems suitable for mobile equipment applications. Our systems for mobile applications feature compact, lightweight designs with vibration-resistant components. We offer hydraulic stations with small footprints, high-pressure capability, and efficient cooling for demanding environments. We can also integrate our systems with mobile control interfaces and design for easy access in space-constrained equipment. Our experience spans construction machinery, mining equipment, and specialized mobile applications.
Our high pressure hydraulic cylinders are designed with safety factors that exceed industry standards. We use premium alloy steels, often forged for critical components, and employ advanced sealing technologies with redundant seal profiles. Each cylinder undergoes rigorous testing, including hydrostatic testing at 1.5 times the rated pressure, to verify integrity. We also perform non-destructive testing on critical welds and components. Our design process includes finite element analysis to optimize the cylinder structure for pressure containment and fatigue life, ensuring long-term reliability.
Yes, our hydraulic working platforms can be fully integrated with automation systems. As a leader in integrated mechanical-hydraulic-optical intelligent equipment, we equip our platforms with sensors for position, load, and status, along with PLC controls that communicate via industrial Ethernet protocols. This enables automated height adjustment, synchronized operation with other equipment, and real-time monitoring. Our platforms can be programmed with multiple preset positions and integrated into robotic work cells or fully automated production lines.

Customer Reviews

Carlos Mendez

We needed specialized metallurgical hydraulic cylinders for a walking beam furnace application, where the cylinders are exposed to extreme radiant heat and must operate reliably. Tianjin Uranus engineered cylinders with integrated water-cooling jackets and high-temperature seals that have performed exceptionally well. The cylinders have been in operation for over two years with no downtime related to cylinder failure. The custom design included special mounting brackets that simplified installation. The Uranus team was collaborative throughout the design process and delivered a solution that perfectly met our needs. Their expertise in metallurgical applications is evident.

Heinz Mueller

Our hot strip mill has been using Tianjin Uranus metallurgical hydraulic cylinders for roll bending and positioning applications for the past five years. These cylinders operate in an extremely harsh environment with high temperatures, water spray, and heavy scale. The cylinders have proven to be exceptionally durable, with seal life far exceeding other brands we have used. The rod coatings resist abrasion, and the corrosion protection has prevented rust. The Uranus team provided custom cylinder designs with features specific to our mill, and their support has been outstanding. These cylinders have significantly reduced our maintenance downtime.
