Fast Cooling

With advanced high-strength steels and high value-added steels development, it is very important to improve the cooling capacity and cooling intensity of the run out table cooling system. The key technology is to break the vapor between hot strip and cold water and to increase the direct contact area. In order to realize the ultra fast cooling, Laboratory research such as jet nozzle type selection and diameter of nozzle decision and factory tests such as cooling capacity testing have been done. Experiment results show that circular nozzle has bigger hitting power than fan-type nozzle. However, drainage capacity caused by fan-type nozzle is better than that by circular nozzle. In addition, nozzles of different diameters have nearly the same cooling capacity despite of the very different water flow. Cooling power testing results show that cooling capacity is enhanced with pressure increasing and with speed decreasing.

Hot Rolled

Hot strip cooling temperature and its cooling rate is get by strip cooling system and coiling temperature of hot rolled strip is an important parameter on its performance index. It presents laminar cooling system of the 700 mm hot strip mill and the mill rolling process is present, the laminar cooling system is analyzed on the rolling theory and techniques. The laminar cooling system and its problems are present. The improvement programs of laminar cooling system are present, The control system of laminar cooling system is present combining feed-forward main control and feed-backward self-learning control, and measuring instruments is reinstall and water valves is improved. It could be a reference for the similar mill units and new building rolling mills.
