Rotary Unions Exporter
IRON & STEEL INDUSTRY
The steel industry is one of the largest users of rotating unions primarily for continuous casting machines (CCM) which use Rota-Tech 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 centres that require hydraulic unions for actuation of mandrels. Molten steel is poured from massive ladle turrets into a mould 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. Metal service centres perform such cold-processing as slitting or cutting coils, stamping sheet and more. Rota-Tech hydraulic unions are used for holding of the steel rolls, and actuation of mandrels.
In continuous casting process hot steel is cooled with rolls. These rolls are cooled with water. While hot steel passes, these rolls rotate and CCM Rotating Joints are used to transfer water from stationary supply lines to rotating rolls. In addition, withdrawal and straightening units are cooled with water by using CCM rotary joint in the shaft mounted rotating joints.
