ALUMINUM COLD ROLLING MILL — A SINGLE HIGH-PRECISION MILL FOR BOTH BREAKDOWN AND FINISHING

Primetals Technologies' aluminum cold rolling mills offer a blend of innovative design and proven technology for both new and revamp projects. This enables strip to be produced at very tight tolerances and productivity levels resulting in maximum yield.

Markets served by customers include transport, construction and packaging. An accurate mill setup is crucial for meeting quality requirements. For this reason, Primetals Technologies cold rolling mills use physical on-line process models. Our solutions also feature fully integrated process control, automation and drive systems using industry-standard platforms to allow for optimum rolling results at any time.
