The online minimizing technology of viscous tin.
Background technology
In float flat glass technique, master operation be raw material proportioning, melting furnaces fusing, tin groove forming, annealing kiln anneal,
Cold end cutting etc., is coupled with flow liquid road between melting furnaces and molten tin bath, is coupled between molten tin bath and annealing kiln with transition roller table, molten tin bath is into
Type equipment, the tin liquor for containing fusing, the glass metal of fusing enters molten tin bath, and the plate glass outlet molten tin bath of shaping, shaping is former
Reason is to swim in glass metal in tin liquor to shakeout and form plate glass.
Because tin liquor is oxidizable, therefore the protective gas that nitrogen is mixed with hydrogen must be injected into molten tin bath, make the beginning in molten tin bath
Malleation is kept eventually, protective gas injects from tin groove roof, import and export blowout from molten tin bath and gap is oozed out.
In actual use, always have a small amount of oxygen reversely to penetrate into molten tin bath, aoxidize tin liquor, produced in molten tin bath many
Plant chemical reaction.Under high temperature and Hypoxic habitats, the oxidizable generation stannous oxide of tin liquor（SnO）Gas, floats towards the low temperature of end
Qu Hou, after temperature is down to below 870 DEG C, stannous oxide gas can become the solid powder of sn-containing compound；In high temperature and richness
Under oxygen environment, the oxidizable generation tin oxide of tin liquor（SnO2）Solid powder；Stannous oxide and tin oxide can also be reduced into tiny
Tin drips；These stanniferous things are shed on plate glass band, will result in the pollution of plate glass belt upper surface.

Make the vibration per second of its interior molecules atom, rub as many as more than one hundred million time heating using microwaves.Metal object is heated, electromagnetism working frequency
For several KHzs（KHZ）To more than hundreds of KHzs, hardware heating and precious metal smelting are commonly used for.For example, using microwave
Stove, using two same porcelain cups, one empty, a dress water, while after heating 1 minute, empty cup is not warm, dress cup and water are equal
Heat, that is can to penetrate porcelain cup heating water because of microwave, and water heats porcelain cup.It can be seen that, can be fast using specific electromagnetic frequency
Speed heating predetermined substance, without heating or heating other materials slowly.
A kind of ideal method for removing the viscous tin of residual on plate glass is not yet found at this stage through retrieval extensively, by
In the special property of high frequency induction heater, the applicant devises a kind of method for removing the viscous tin of plate glass residual to make
With.
