Layout and calculation of laminar cooling equipment in hot rolling mill

The preliminary design of water-cycling system has been undertaken about laminar cooling in hot rolling mill. The method of calculating high cistern’s volume and pumping station’s water supply capacity of laminar cooling has been put forward. The laminar cooling system has adopted an independent water-cycling system, which ensures the stability of the water quality and water pressure. At the same time, high cistern’s volume and pumping station’s water supply capacity when product the harshest steel have been calculated. Moreover, hydraulic calculation of laminar cooling has also been done, and the header’s outlet flow and capacity of laminar cooling have been deduced. These efforts can not only make the laminar cooling equipment more compact and saving cooling water, but also offer reference to deep design and laminar cooling equipment’s layout.
