Industrial Experiment of Reducing Superheat of Steel by Nozzle Cooling

Nozzle cooling equipment is developed to supervise and control the heat flux by changing water flux. An industrial experiment is held in billet caster in Huaigang. The results show that cooling control system works stably and effectively to control the heat fluxes by the temperature of copper tube. The superheat of steel in mould is reduced and the equiaxed crystal ratio, as well as compact degree of steel is raised.
