Description

A kind of dedicated annealing kiln of float glass

Technical field

The utility model relates to a kind of dedicated annealing kilns of float glass, belong to float glass technolog field.

Background technique

The forming process of float glass is completed in the molten tin bath for being passed through protective gas.Melten glass is from tank furnace It continuously flows into and swims on relatively denser tin liquor surface, under the action of gravity and surface tension, glass metal is in tin liquor Spread out, shakeout on face, formed smooth upper and lower surface, hardening, it is cooling after drawn upper transition roller table.The roller turn of roller tables, glass Glass band pulls out molten tin bath and enters annealing kiln, and annealed, cutting just obtains float glass product.

At present in the production process of float glass, wherein annealing kiln be in floatation glass production line connect tin groove forming and Glass cold-end cutting carry an important equipment, the effect of annealing kiln be exactly by glass tape by pull-out molten tin bath when temperature, press The process gradually to cool down is required according to annealing process, glass tape is gradually cooled down by annealing kiln in order to cut and carry.If Temperature then needs suitably heating and soaking lower than annealing ceiling temperature when glass tape enters annealing kiln；If glass tape enters annealing Temperature is higher than annealing ceiling temperature when kiln, then needs suitably cooling and heat dissipation.

Current float glass lehr have following defects that 1), the glass plate that comes out in molten tin bath by annealing kiln into Mouth is to prevent the high temperature heat in molten tin bath from interfering the annealing in annealing kiln hence into annealing operation is carried out into annealing kiln at present Operation is usually provided with check apron in the entrance of annealing kiln, and the check apron is made of thermal insulation board, and the effect of check apron is exactly to stop this A little huge heats enter annealing kiln, separate outside air with furnace air.The check apron at work, relies primarily on itself and glass Plate infinite approach can separate the heat outside annealing kiln in this way and enter annealing kiln, guarantee that glass presses lehr attendant in annealing kiln Skill requires operation；But the drawbacks of this check apron, is: to guarantee that heat insulation, the check apron infinitely connect with glass plate to greatest extent Closely, if this makes the thickness of glass plate change, that is, need to adjust the position height of check apron in time, this easily influences float glass process The continuous production of glass；If do not adjusted, the annealing operation effect of annealing kiln will be will affect, to influence float glass The quality of production.

2), current annealing kiln is different in the temperature of different zones, usually presses according to the direction that glass plate advances It is successively reduced according to the temperature gradient set.Usually inside control annealing kiln each regional temperature be arranged side on a glass or The cooling water pipe of lower section, by the parameters such as the initial water temperature of cooling water, flow, flow velocity inside control different location cooling water pipe from And control the temperature in each region inside annealing kiln；But in the thicker float glass of some thickness of production, due to float glass Thickness it is thicker, and the thermal coefficient of float glass itself is lower, when this makes float glass be annealed in the annealing kiln, The cooling water pipe is straight type structure, and the temperature difference around the cooling water pipe is usually no more than 2 DEG C, and the float glass process that thickness is thicker For glass plate since the heat dissipation at intermediate position is slower, the temperature difference between the temperature and edge at in-between position can even reach 22 DEG C or more, this easily causes Float Glass Surface compression chord, and inside is by tensile stress, thus easily float glass is caused to bend, Influence the quality of production of float glass.
