Purpose

Development of technology of hot rolling coils using thermo- mechanical controlled process for the wide-strip rolling mill and grade estimation of coils.

Methodology

Technology was developed and the first batch was produced using thermo-mechanical controlled process and improvement in surface quality was achieved via air cooling to a certain temperature.

Findings

There has been developed technology, and pilot batch of hot rolling coils (6×1500 mm, steel grade S355MC) has been produced using thermo- mechanical controlled process (TMCP) for the wide-strip rolling mill 1700. The integrated technology for TMCP coil production (steel grade S355MC) has been firstly developed for the rolling mill 1700 in accordance with EN 10149-2. Air cooling for coils to 450°C after coiling has been firstly used in the developed technology, which provides for decrease in air scale and improvement of surface quality for the customers.

Keywords: thermo-mechanical controlled process, hot rolling coils, rolling force, temperature conditions, technology
