Hot Rolling Mills for Aluminium Industry

Hot Rolling Mills for Aluminium Industry Hot Rollings Mills Hot Rolling Mills are key process equipment in the production of Aluminium Flat products. They are used in the conventional production route hot rolling plants and also in conjunction with the Hazelett Casting technology to make an efficient and productive Continuous Casting Hot Rolling Process. Due to the multi stands configuration, which guarantee also modularity in terms of financial investment, the Continuous Hot Rolling Mills meet the flexibility levels requested by the Aluminium Industry. To address the challenges of the industry, FATA Hunter has introduced on the market, a mill design which integrates the latest equipment and technology developments in order to meet the expectation of the Aluminium Producers.

Hot Rolling Mills for Aluminium Industry Hot Rolling Mill Expandability On the next pages are described different plants and different production capacity in terms of quantity and quality. As clearly shown, a new plant can be designed in order to be scaled in different future steps, starting with a low profile of investment and production and growing-up in several steps, depending on the market requirements and company expansion capacity.
