High-Temperature Metallurgical Hydraulic Cylinders

In extreme high-temperature environments typical of steel manufacturing—such as electric arc furnace areas, continuous casting strands, and hot strip mills—conventional hydraulic cylinders frequently suffer from rapid seal carbonization, fluid breakdown, and catastrophic structural thermal fatigue. Plant engineers and maintenance superintendents struggling with radiant heat exposure, hot scale impingement, and thermal expansion regularly face unexpected production downtime and premature component failure. To eliminate thermal degradation and ensure uncompromised operational continuity in extreme thermal environments, Tianjin Uranus engineers advanced high-temperature metallurgical hydraulic cylinders built specifically for severe steel production settings. Fabricated within our expansive 45,000-square-meter state-of-the-art production base under stringent ISO 4413 standards, these cylinders utilize advanced heat-resistant seal compounds, specialized thermal barrier materials,

Customer Reviews

Sergei Petrov

Our heavy plate leveler is a demanding application with high shock loads and extreme pressures. Tianjin Uranus designed metallurgical hydraulic cylinders specifically for this application, with forged components and heavy-duty bearings. The cylinders have now exceeded four years of continuous service without any issues. The quality of the machining and assembly is evident, and the cylinders have maintained their performance. The Uranus team provided detailed documentation and was very responsive throughout the project. We have since standardized on Uranus cylinders for other critical mill equipment. I highly recommend them.

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.
