Modelling and Real-Time Simulation for Hot Coil Marking
1.1 Background. In compact strip production (CSP) mill, hot coil is made by rolling process. Slab is cut to the pre-decided length and this hot slab is directly fed to the tunnel furnace (of length 185–260 m). In tunnel furnace slab, temperature is equalized across the cross-section. Temperature of slab at entry of tunnel furnace is about 950 ...

Mathematical Model to Analyze Coiling Feasibility at Downcoiler in Hot
The coiling of a steel strip in a Downcoiler is an integrated part of the hot-rolled steel production line. Failure to coiling results damage to finished rolled strip along with mill downtime due to cobble. Thus, coiling success in Downcoiler is a critical concern for production of hot rolled steel strip. A mathematical model has been developed to …
