The inventive multi-lane transport systems may employ wire mesh belts having a flying bridge wafer support system comprising longitudinally spaced carrier wire elements that support the wafers at their side edges at only point contacts, by means of opposed, inwardly inclined, downwardly slanted segments or wings. Alternately, finger drives comprising spaced-apart chains having inwardly projecting fingers may be used for transport of the wafers by side edge contact. Friction or sprocket drives having tensioner assemblies associa-ted therewith are used to move the transport belts or finger chains through the furnace zones. Each lane may be independently controlled to provide unique thermal profiles along their processing paths.

Roller hearth furnace and method for the heat treatment of metal sheets

Номер: US20160024609A1

The invention relates to a roller hearth furnace for the heat treatment of coated metal sheets as well as to a corresponding method. The objective of the invention is to put forward a roller hearth furnace that allows the alternating processing of AlSi-coated metal sheets and metal sheets with zinc alloy coatings for hot-working, whereby considerably less effort is involved for the alternating procedure than is the case in the state of the art. The roller hearth furnace according to the invention for the heat treatment of coated metal parts is characterized in that it has at least a first zone and a second zone, whereby in the first zone, a temperature below the melting temperature of the AlSi deposits or a temperature of more than approximately 900° C. [1652° F.] can be maintained, whereas in the second zone, a temperature of more than approximately 870° C. [1598° F.] can be reached.

The glass displaces reciprocatively in multiple directions to be heated up more uniformly, which effectively reduces formation of the thermal stress marks on the glass. Since the rollers displace along the Y axis at the same time, the glass on the rollers does not have the displacement of the Y axis in respect to the rollers, such that friction of the displacement of the glass is reduced, which more effectively reduces formation of the thermal stress marks on the glass. 1.
