Abstract：This study focuses on the energy-saving effect of the coupling between the online thermal width adjustment function of 230-1 650 mm double flow slab and the width reduction function of the fixed width press of the 1 780 mm hot rolling mill in Guangxi Iron and Steel Group. Research has found that the application of the casting machine's hot width adjustment combined with the pressure fixed width machine process effectively saved about 17 561.5 MWh in August last year， reducing approximately 5 699 tons of carbon dioxide emissions.
