The cooling unit includes a cooling circuit that supplies cooling fluid to the cooling chamber (40) to provide cooling of the aligned set of roller ends (30) and the bearings (42).

A base material for a disk roll, the base material including: 5 to 9 wt % of ceramic fibers, 20 to 40 wt % of kibushi clay, 2 to 20 wt % of bentonite and 40 to 60 wt % of mica.

The present invention discloses a method for processing a columnar curved tempered glass. The method specifically comprises the following steps. Bending and tempering of the high temperature flat glass are divided into two stations. Bending is firstly carried out on the high temperature flat glass output by a heating furnace; the columnar extending direction of the curved glass is perpendicular to the direction the glass output from the heating furnace in the bending process, and then the formed curved glass is output to a tempering station in the columnar extending direction thereof to undergo tempering. In the present invention, bending and tempering of the high temperature flat glass are completed by two stations to break the normal procedure that bending and tempering are carried out by a single bending device intensively, thereby providing a novel technological approach for processing the columnar curved tempered glass.

The present invention discloses a device for processing columnar curved tempered glass. The device mainly comprises a glass heating furnace, a glass bending mechanism and a glass tempering mechanism connected sequentially, wherein the arrangement of each supporting roller in the rollers supporting the high temperature flat glass is changed from planar arrangement in space into curved arrangement corresponding to the shape of the glass to be formed, so that the glass bending mechanism enables the glass to suffer bending deformation. Transferring rollers for outputting the formed curved glass in the axial direction of the supporting roller are arranged at the clearance of the rollers of the bending mechanism. In the present invention, bending shaping and tempering of the high temperature flat glass are completed by two stations to break the normal procedure that bending shaping tempering are carried out by one bending appliance intensively, thereby providing a novel technological approach for processing columnar curved tempered glass.
