Steel Industry

 
Steel Industry

The steel industry is one of the largest users of rotating unions primarily for continuous casting machines (CCM) which use Deublin rotating unions to cool the numerous rolls that support molten slabs as it moves by gravity through various segments onto a run-out table to downstream annealing and heat treating. The slab is formed into coil or sheet. Coil is further converted in processing centers that require hydraulic unions for actuation of mandrels.

Continuous Casting Machines

Molten steel is poured from massive ladle turrets into a mold that pushes thru various segments over hundreds of water-cooled rolls, and eventually to a run-out table for further processing. The slab is converted into sheet or coil.

Coil Processing Mandrels

Metal service centers perform such cold-processing as slitting or cutting coils, stamping sheet and more. Deublin hydraulic unions are used for holding of the steel rolls, and actuation of mandrels.

Welcome to Deublin.com!

Since 1945, Deublin has grown from a small garage shop to the world’s largest manufacturer of rotary unions (rotating unions). Our worldwide distribution network allows OEM’s all over the world to specify Deublin rotary unions when purchasing equipment made in another country. Wherever you’re located, Deublin has a stocking distributor nearby to meet your fluid handling requirements—quickly. Rotary unions must accommodate a broad range of materials, viscosities, temperatures, pressures and speeds. That’s why the Deublin rotary union product line offers over 500 standard rotary unions, over 3,000 separate models, and more than 6,000 individual components to handle them.
