Abstract:
A lift-up roller arrangement for electronic float glass, including a plurality of lift-up rollers rotatably arranged on the inner wall of an annealing kiln, wherein a plurality of boron nitride rings are fixedly sleeved on the outer side wall of each lift-up roller; a heat-resisting steel tubes is arranged on each of both sides of each lift-up roller; a plurality of exhaust holes are arranged on an outer side wall of the heat-resisting steel tube; the heat-resisting steel tube is in communication with an external hot gas supply case; and a plurality of cleaning assemblies used in cooperation with the lift-up rollers are arranged at the inner bottom of the annealing kiln.
Abstract:
A conveyance device for glass sheets advancing them one after the other, includes at least one roller including a glass sheet conveyance area, the device including actuators located on either side of the conveyance area capable of bending the roller within its elastic deformation domain while leaving it able to be driven in rotation around fixed centers of its sections, wherein the roller includes a shaft and a plurality of bending rings into which the shaft is inserted.
Abstract:
Provide is a heat-resistant roll with improved effectively characteristics, a production method thereof, and a method of producing sheet glass using the heat-resistant roll. A method of producing a heat-resistant roll equipped with a roll portion containing 5% by weight or more of clay includes: a grinding step (S101) of grinding a roll surface of the roll portion; and a surface treatment step (S102) of performing surface treatment of smoothening the ground roll surface in a wet state.
Abstract:
The invention relates to a method and to a device for ceramizing green glass in a continuous furnace, with the ceramization being carried out directly on rollers.
Abstract:
A device for bending sheets of glass running between a bed of upper rolls and a bed of lower rolls forming a shaping bed that pinches the sheets as they run, the shaping bed being disposed in a path having a curved profile in the running direction of the sheets of glass, the shaping bed including at least one roll of what is known as the rod/sheath type including a fixed metal rod preformed in a curved profile lengthwise and a flexible sheath that is able to rotate about the rod, the sheath being rotated about the rod. The roll of the rod/sheath type may include a metal rod preformed in a curved profile lengthwise and a flexible sheath that is able to rotate about the rod, the sheath including a first envelope made of a polymer material and a second envelope made of a flexible metal material disposed around the first envelope, the first and the second envelope rotating together as one.
Abstract:
A glass production method is provided that includes a forming step of forming a glass ribbon from molten glass by a glass forming unit, and a conveying step of gradually cooling the glass ribbon to a temperature less than or equal to a strain point temperature of glass while conveying the glass ribbon by conveyance rolls. The conveying step includes a buffer layer forming step of forming a buffer layer made of an inorganic salt by spraying a solution containing the inorganic salt directly onto at least a portion of the conveyance roll and causing the solution sprayed onto the conveyance roll to dry out.
Abstract:
A downstream roll for glass manufacture comprises at least one millboard piece. At least a portion of an outer peripheral surface of the downstream roll comprises infiltrated ceramic particles. The infiltrated ceramic particles are infiltrated to a depth of about 1 mm to about 10 mm. Further examples of the disclosure include methods for manufacturing a glass ribbon and a downstream roll for glass manufacture.
Abstract:
A disc roll includes a plurality of annular disc members each defining a hole and having a peripheral surface; and a rotary shaft fitted into the holes of the annular disc members by insertion, whereby the peripheral surfaces of the disc members serve as a conveying surface of the disc roll. The disc members include an inorganic fiber, mica and a clay having a content of particle components that have a particle size of 5 μm or larger of not higher than 30% by weight based on the weight of the clay.
