Method and means of temperature control

摘要

An apparatus and a method for controlling the lateral temperature control of hot material on a roller table of a hot roller mill employs adjustable heat-insulating panels (32) below the hot material travel path (28), between the rollers of the roller table. Between each successive pair of rollers (2) a number of the heat-insulating panels (32) are arranged side by side, as a group spanning the width of the table. At least away from the entry end of the table, panels of each group can be displaced selectively to allow a greater loss of heat from a central region of the hot material between its side edges than in the side edge regions themselves. The selective displacement of the panels can be preprogrammed to be determined by the characteristics of the hot material entering the roller table.
