Description
Technical field
The invention belongs to float glass manufacturing technology field, it is related to transition roller table technology, and in particular to a kind of float glass
Transition roller table and the method that glass chieftain is firstly introduced to it.
Background technology
Float glass transition roller table is the key equipment between molten tin bath equipment and annealing kiln, belongs to prolonging for molten tin bath equipment end
Continuous, its major function is that the glass tape for extracting 600 DEG C or so from molten tin bath introduces annealing kiln, and whether its structure is reasonable, sealing
It is whether tight, it is related to the stabilization that the raising of molten tin bath internal pressure is produced with molten tin bath, directly affects the quality of production of float glass.
Now in the art, run at a high temperature of the roller of transition roller table is generally more than 600 DEG C, and roller mostly uses alloy roller, this
Kind of material is easily affine with the stannide such as SnS, SnO from molten tin bath at high temperature, and corrosion roller surfaces or produced on surface are difficult
The buildup of removing, it is easy to cause lower glass surface to scratch, badly influence formed glass goes out roller quality.
Current float glass transition roller table is usually provided with wiping tin device, and the slag case and wiping tin device of transition roller table are general
For integral type structure, therefore wipe tin device and play two effects, that is, the tin and tin oxide on roller are wiped, while under glass tape
Play sealing function in surface, it is ensured that stand intact by the glass surface of transition roller table.In the conventional technology, tin device is wiped usual
The graphite block for wiping tin device is supported using bridge architecture, and graphite block is withstood using leaf spring and realizes roller bottom and graphite
Block is in close contact.And leaf spring gradually produces amount of deflection, generally 20~25mm or so in 600 DEG C of temperature environments；While bridge-type knot
Structure and roller can also produce amount of deflection in itself, and the amount of deflection that roller is produced applies pressure to graphite block so that graphite block structure
It is deformed, therefore the wiping tin device is also easy to produce steps on waist phenomenon at high temperature, causes wiping tin device to be in close contact with roller,
Tin and its oxide on roller can not be wiped, the sealing function that can not have been played.
Existing transition roller table generally connects slag case, check apron etc., and the big heat-retaining condition in space is bad, and glass tape enters from molten tin bath
Cooling is produced when entering transition roller table, the formation to the annealing stress of glass is very unfavorable, influence the cutting yield rate of glass, cause to put down
