Tandem rolling mill give multiple production,requires continuously reduce steel plate thickness at hundreds of meters per minute.

The continuous rolling is realized by one way from uncoiling to coiling and working without stop, automatic shear and welding machine, strip accumulator and double recoilers are on the rolling line.

Automatic shear & welding and spiral accumulator keep uncoiling and strip feeding continuously, double coilers keep continuous coiling. These characters of tandem rolling machine make automation and production go to maximum scale.

Two Coilers working: strip head comes to one coiler, belt wrapper holds the head and wraps it onto coiling mandrel, the steel strip start coiling up on the mandrel, speed up the coiling speed until maximum stable speed, when the coil tail welding seam comes close to the coiler, slow down the mill line, cut off the strip after tail welding seam.

Coil head will go to the other coiler and repeat the above process. The whole mill line continuously work, just slow speed down during the exchange between two coilers.
