Title: Glass pane roller hearth furnace - has temp. control for upper heaters according to panel size and movement
Inventor: KRAMER CARL PROF DR ING
IPC: F27B9/06
Filed: 1990-03-16
Abstract: For the control of the heated zones in a roller hearth furnace, for flat glass panes, the nominal value selected for the temp. of the heated zones above the glass is higher than that for the other zones which do not deliver heat directly at the glass.  According to the heating of the glass pane, the nominal value difference between the upper heating zones is reduced, which bear directly down on the glass. The heaters have a low thermal time constant. The nominal value for the heating zones directly affecting the glass panes partially from above is at a value between the nominal values for the heating zones affecting the glass pane directly and indirectly. On reversing the movement of the glass pane on the roller hearth, the nominal value of the heater directly above the glass is adjusted between the nominal value temps. of the zones giving a long-term heating and the heating zones giving an indirect heat, for the dwell time of the pane, according to the reverse movement. The heating zone sizes increase from the centre of the furnace out to both sides. Different heating zone sizes are assembled to give a different number of heaters in a variable array through adjustment requirements or through controlled adjustments.  The data on the glass pane dimensions are taken automatically on entering the furnace, or  input from a feed table before it enters the furnace, using at - least one switch bar between the rollers of the feed table with a contactless action. ADVANTAGE - The strong heating action on the glass from below -matches the pane format and movement, compensated by activation of the upper heaters.
