PROCESS OF HOT-ROLLING STEEL, WHEREIN HEAT LOSS FROM THE STEEL IS REDUCED BY MEANS OF ONE OR MORE HEAT-REFLECTING SCREENS AND APPARATUS FOR USE IN THE PROCESS

摘要

In a process of hot-rolling steel wherein use is made of a heat-reflecting screen (13) by which heat radiating from the work (1) is reflected back to the work, the invention comprises the step of cooling the heat-reflecting-surface (10) of the screen during use, e.g. by flowing fluid coolant along the paths (18) in heat-conducting relationship to such heat-reflecting surface.
