Heavy-Duty Rotary Joint for Steel Casting and Rolling Mills

Description

The Rotary Joint for Casting and Rolling Mill is a precision-engineered rotary union designed specifically for the demanding requirements of steel production lines. Built with advanced materials and cutting-edge sealing technology, this rotary joint ensures reliable fluid transfer between stationary and rotating components, even under extreme conditions of high temperature, high pressure, and continuous operation.

Whether used in continuous casting machines, hot rolling mills, or cold rolling mills, our rotary joint delivers exceptional performance and longevity, reducing downtime and maintenance costs. It serves as a cost-effective alternative to well-known brands like Deublin, Maier, Kadant, and Johnson-Fluiten, while maintaining equivalent quality standards.

Our rotary joints are specifically designed for heavy-duty industrial applications, such as casting and rolling mills. They combine superior craftsmanship, exceptional performance, and flexible customization to serve as a reliable and indispensable partner on your production line.

We employ highly skilled welding craftsmen to ensure every rotary joint possesses superior structural integrity with flawless, smooth seams. Each unit is meticulously finished to be neat and burr-free, a standard that reflects not just aesthetics but our deep commitment to precision manufacturing and product reliability. This unwavering attention to detail guarantees long-term, stable performance even under the harsh conditions—high temperatures, high pressures, and contamination—typical of casting and rolling mill environments.

We understand that every production line is unique. With our comprehensive manufacturing facilities and experienced engineering team, we offer fully customized solutions tailored to your specific operational requirements. From custom dimensions and material selection to specialized connection types and designs for extreme working conditions, we collaborate closely with you to create the perfect rotary joint that seamlessly integrates with your application.

Applications in Your Facility

The Dann rotary joint is not a one-size-fits-all solution; it’s a versatile platform proven across a spectrum of critical mill applications:

Continuous Casting Machines (CCM)

As a CCM rotary joint, it provides a reliable supply of cooling water to the mold, segments, and withdrawal rolls. Its robust design handles the high water pressure and particulate matter common in these systems, preventing costly breakouts and ensuring consistent slab or billet quality.

Hot Rolling Mills

In the hot mill, our joint excels as a hot rolling rotary union. It delivers high-pressure cooling water directly to the work rolls, managing thermal profiles, extending roll life, and ensuring proper material gauge and surface finish. It can also be configured to handle steam for roll heating applications.

Cold Rolling Mills

For cold reduction and finishing mills, precision is key. Our cold rolling swivel joint provides a leak-free conduit for hydraulic fluid used in roll bending and shifting systems, as well as for applying rolling oils and coolants, guaranteeing the operational accuracy required for high-quality finished products.

Other Applications:
Annealing and Processing Lines
Downcoilers and Uncoilers
Tunnel Furnaces
Ladle Turrets
