Taiyuan Heavy Industry Hydrodynamic Bearings Power China First 3500mm Stainless Steel Plate Production Line

Recently, good news came from the user site that the first domestic 3500mm stainless steel medium and thick plate production line equipped with TZCO oil film bearings successfully passed the hot test, once again demonstrating the absolute strength of TZCO oil film bearings in the field of high-end rolling mills.

In this project, the TZCO oil film bearing is a core component of China's first 3500mm stainless steel Steckel mill. Its maximum load capacity exceeds 10,000 tons, equivalent to the weight of 170 high-speed rail carriages, providing a solid foundation for the production of high-quality plate.

As the "heart" of the rolling mill, the performance of the oil film bearing directly determines the stability of the mill's operation, as well as the dimensional accuracy and shape quality of the products. Where does this unwavering "10,000-ton capability" come from?

Craftsmanship forges a "steel mirror"

Under the pressure of 10,000 tons, even the slightest difference is crucial to the success or failure of the plate. The oil film bearings provided by TZCO meet stringent manufacturing standards: the inner and outer diameter coaxiality error of the tapered sleeve, the core bearing component, is strictly controlled to within 0.005mm, equivalent to one-sixteenth the thickness of a human hair. Furthermore, the bearing's working surface finish reaches mirror-grade finish—the roughness of the tapered sleeve's working surface is only 0.05μm (micrometers), and that of the bushing's working surface is between 0.2-0.4μm. This significantly reduces operating resistance and creates a more stable oil film, evenly dissipating tens of thousands of tons of pressure and efficiently carrying loads.

Unique Design: "Strong Bones"

Tens of thousands of tons of load capacity is inseparable from unique structural support. TZCO's oil film bearings incorporate multiple design features: a thin-walled structure based on a keyless tapered sleeve improves load capacity; a novel foot-shaped seal effectively blocks external cooling water intrusion while preventing internal lubricant leakage, facilitating maintenance; an online temperature measurement device provides a clear overview of the bearing's operating status, ensuring more scientific and safe operation; and a fully symmetrical double-thrust design enhances component versatility and interchangeability, greatly facilitating spare parts management and installation.

Professional Service: "Guarding the Journey"

Excellent design and manufacturing ensure timely delivery; and precise on-site installation ensures first-time success. The professional and efficient support of TZCO's technical team throughout the entire process laid a solid foundation for the smooth progress of the hot test. After the equipment goes into production, after-sales personnel will conduct regular visits to understand operating conditions and assist in resolving any issues. This professional commitment, rooted in craftsmanship and culminating in trust, is the solid foundation of TZCO's quality.

The company will continue to deepen its commitment to technological innovation, leveraging its proven capabilities to propel high-end rolling mill equipment to new heights and injecting "TZCO power" into more major projects.
