A continuous automated procedure for manufacturing concave monolithic reflectors (1) for a solar conversion system by heating a glass sheet (200) placed on a mold (201), by making the glass in a mold under gravity, characterized in that it is provided A method comprising the steps of: providing a mold (201) having a surface with adjacent concave grooves (220) intersecting enclosures (221) forming a corrugated mold surface (218), such that the surface profile corrugated (222) defines the form that the glass (212) will take when a sheet of glass (200) is heated and warped during the modeling process, and in which the corrugated mold surface (218), the mold (201) they have a substantially concave surface (204) and laminated edges (203); place the glass sheet (200) on top of the mold (201); irradiating the upper surface of the glass (200) with intense radiant energy to quickly bring the glass (200) to the melting temperature, whereby a glass sheet is obtained in warp (214), in which the sagging and erasing of the glass is quickly achieved by gravity, until the sheet of softened glass (212) comes into contact with the line of ridges (221), and is placed between them, and the sheet of softened glass (212) adopts its general shape as defined by the surface profile at the highest point of the ridges (221); laminate the edges (219) of the glass (212) to form the curved edge (203) of the mold (201); as soon as a contact is created in the inside the mold (201), and the glass (212) lightly touches and rests on the mold slides (211), quickly cooling the glass to avoid continued sinking between the ridges (221); and minimize thermal conduction from the mold (201) to the glass (212) during the thermal modeling cycle using the surface of the corrugated mold (218) to limit the contact area (221) between the glass (212) and the mold ( 201), and cover the surface of the mold (201) with a high reflectance coating. |
