Method and furnace for bending glass sheets. |
摘要 |
<p>Glass sheets are heated to a bending temperature by supporting them on a ring mould (11) and carrying them from one heating station to another. In a heating and bending station (4), the glass sheet is heated for effecting a desired bending partially or entirely through the action of gravity. During a bending operation, the temperature distribution of radiation heat is adjusted. In at least one of the heating stations (2,3,4) for preheating (2), prebending (3) or bending (4), the glass sheet is subjected to the action of convection blasting (forced convection) in addition to the radiant heat from electric resistance heaters (12) mounted above the glass sheet. <IMAGE></p> |
