  • Heating and shaping system using microwave focused beam heating
    Patent number: 9108875
    Abstract: A furnace for shaping glass sheets for aircraft transparencies using the cut-to-size method includes a preheat and cooling furnace defined as a first furnace, and a shaping furnace. A conveyor geared for reciprocating movement moves a bending iron supporting a glass sheet through the first furnace set to a preheat temperature. The glass sheet supported on the bending iron is heated in the shaping furnace by microwave beams from a gyrotron to heat portions of the glass sheet to be shaped to a complex shape. After the sheet is shaped, the conveyor moves the bending iron supporting the shaped glass sheet from the shaping furnace through the first furnace set to a cooling cycle.
