Description
Technical field
The present invention relates to the manufacturing of plate glass.More specifically, the present invention relates to be used to control by for example improvement carry-over pinch rolls of the thickness of the glass of overflow downdraw fusion process production.Concrete value of the present invention is the production of high quality flat glass sheet, and it shows lower blemish.This glass can be used as for example substrate of LCD of flat-panel monitor.
Background technology
Carry-over pinch rolls are used for the manufacturing of plate glass tension force is applied to glass tape (flat board is formed by glass tape) and thereby control nominal slab-thickness.For example, in overflow downdraw fusion process (referring to document: U.S. Patent No. 3,338,696 and 3,682,609) in, thereby carry-over pinch rolls are arranged in the downstream of the end of melting tube or root and are used for regulating the nominal thickness that the glass tape that forms leaves the speed of pipe and determines the finished product flat board.Roller is generally over the ground and uses; Formed glass tape is supplied with between roller.
The common features of this roller is included in the special-shaped infusibility cover plate of steel axle top.The abnormity cover plate is its part has different radii with respect to the axis of axle a cover plate.Carry-over pinch rolls generally are designed at its outer edge contact glass tape, particularly, and in the just area inside that thickens flange of the complete edge that is present in band.The contacted part of roller and glass tape is known as the traction pressing plate.It is long-pending to have the contact surface that the use of roller of traction pressing plate minimized between carry-over pinch rolls and the glass, thereby has minimized the damage of plate glass and the wear debris that produces from roller.
Good carry-over pinch rolls need satisfy a lot of competing criterions.At first, roller needs can bear to the long duration and the new relevant high temperature of glass that forms.The time that roller can continue under this environment is long more, then good more, thereby because the replacing of roller reduced give locking equipment fertile finished glass quantity and increased the ultimate cost of glass.Roller also must be able to bear because heating is uneven or because by the shown any internal stress that the different coefficient of expansion produced of different piece of the roller of different materials structure.
Secondly, roller must produce enough tractive force and control thickness of glass.In order not damage the core of the band that becomes useful finished glass, roller only can be on the finite region of its edge contact zones.Thereby required tractive force must only use this zone to produce.Yet the power that is applied to glass can not be too big, because this can produce the surface damage of the useful core that propagates into band.Therefore, roller must be realized balance in that too little and too big power is applied between the glass edge zone.
The 3rd, carry-over pinch rolls must not can discharge the excessive particle (being known as " surface is mingled with (onclusion) ") that can be adhered to glass and formation blemish.For the glass of the occasion of the such demand of substrate that will be used for using such as flat-panel monitor, the surface be mingled with must remain very low because each is mingled with the defect area (for example, one or more defect pixels) of common representative finished product.Because carry-over pinch rolls move under hot environment, seeking the material can enough tractive force be applied to glass tape and can at high temperature do not discharge particle is very difficult challenge.Work that carried out in the past this area and test show, form compression cover plate on the axle, when in this occasion, being used as carry-over pinch rolls cover plate medium with the quartz fibre that forms duromer or aluminium oxide quartz fibre with gluey quartzy dipping and roasting, thereby the colloid quartz particles troop and small amount of fibers is to be picked up and transmitted up the dust and the chip of the main form that stains planar surface by convection current.
The invention solves these defectives of this area and improved carry-over pinch rolls are provided, it has been realized than the higher levels of performance of existing carry-over pinch rolls.
