Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1 and Fig. 2, the molten tin bath 10 that tin liquor is housed of one embodiment of the invention is in float glass.Described molten tin bath 10 comprises wide section 11, narrow section 12 and be connected to the contraction section 13 of described wide section 11 and narrow section 12.The described wide section 11 glass inlet port section 110 comprising glass ware forming section 111 and be connected with described glass ware forming section 111.Described tin liquor is loaded in described molten tin bath 10, forms tin liquor surface 101 in molten tin bath 10.The tin liquor degree of depth described in the present invention is the vertical range of tin liquor surface 101 to the bottom land of described molten tin bath 10.
The tin liquor depth range of described glass ware forming section 111 is 28mm ~ 48mm, further, can be 33mm ~ 43mm, more further, can be 36mm ~ 40mm, is preferably 38mm.The tin liquor depth range of described glass inlet port section 110 is 60mm ~ 80mm, further, can be 65mm ~ 75mm, more further, can be 68mm ~ 72mm, is preferably 70mm.The tin liquor depth range of the contraction section of described molten tin bath is 84mm ~ 94mm, further, can be 87mm ~ 91mm, is preferably 89mm.Described molten tin bath 10 also comprises tin bath outlet 14.As shown in Figure 3, described narrow section 12 has three groups of different spans by described contraction section 13 to the tin liquor degree of depth of described tin bath outlet 14, uses H respectively
1, H
2, H
3represent.H
1span is 28mm ~ 48mm, further, can be 33mm ~ 43mm, more further, can be 36mm ~ 40mm, is preferably 38mm.H
2span is 60mm ~ 80mm, further, can be 65mm ~ 75mm, more further, can be 68mm ~ 72mm, is preferably 70mm.H
3span is 52mm ~ 62mm, is preferably 57mm.
In float glass, high temp glass liquid produces downward surging force when the flow liquid road of higher position enters the glass inlet port section 110 of molten tin bath 10, in order to ensure that glass metal does not touch bottom brick of molten tin bath, so the tin liquor of glass inlet port section 110 of the present invention is large compared with the tin liquor degree of depth of glass ware forming section 111.In addition, in float glass, the temperature of the glass metal of glass inlet port section 110 is higher, when needs artificially process some accidents, in order to avoid manual operation is improper, glass metal is adhered on bottom brick of molten tin bath, so the tin liquor that the present invention designs glass inlet port section 110 is large compared with the tin liquor degree of depth of glass ware forming section 111.
In float glass, because contraction section 13 makes the width of molten tin bath 10 diminish, so at contraction section 13 place, manually by instrument, lamination operation is carried out to sheet glass, if manual operation is improper, sheet glass probably can be made to contact with bottom brick of molten tin bath, and therefore, the tin liquor degree of depth of the contraction section 13 of the molten tin bath 10 of the embodiment of the present invention is dark compared with the tin liquor degree of depth of other positions.In addition, the inequality of temperature is the major impetus of tin liquor convection current, and the tin liquor temperature of described wide section 11 is high, and the tin liquor temperature of described narrow section 12 is low, so can flow to cold zone in the tin liquor of high-temperature zone, contraction section 13 place, the meeting of cold zone is flowed to high-temperature zone, therefore, and dark compared with other positions of the tin liquor degree of depth that the present invention designs contraction section 13, the effect weakening convection current can be ensured, that is, the tin liquor of high temperature weakens to cold zone flowing, and the tin liquor of low temperature weakens to high-temperature zone flowing.The tin liquor degree of depth at contraction section 13 place plays the effect storing pond buffering more deeply.
In conventional float glass production, numerous manufacturer is for the tin liquor depth design of molten tin bath 10, under the prerequisite considering the consumption of saving tin liquor and guarantee glass quality, mostly take following design: the tin liquor degree of depth of glass inlet port section 110 and narrow section 12 is identical, be designed to 82mm, the tin liquor degree of depth of glass ware forming section 111 is darker, be designed to 57mm, this kind of design has been preferably tin liquor depth scheme instantly, reduce although the tin liquor degree of depth reduces tin liquor consumption again, glass quality does not reach the requirement of client.Therefore, numerous manufacturer does not consider to have breakthrough in tin liquor consumption (the tin liquor degree of depth).
And the tin liquor depth design of the molten tin bath 10 of the embodiment of the present invention exactly overcomes this technology prejudice, have employed less tin liquor to complete the production of float glass.Production practice prove, adopt less tin liquor to meet float glass demand completely, and can not bring disadvantageous effect to production.The tin liquor degree of depth that the tin liquor degree of depth of the glass inlet port section 110 of the molten tin bath 10 of the embodiment of the present invention, glass ware forming section 111 and narrow section 12 is all more traditional is more shallow.The tin liquor degree of depth that the tin liquor degree of depth of the contraction section 13 of the molten tin bath 10 of the embodiment of the present invention is more traditional is comparatively dark, but tin liquor total amount in molten tin bath 10 is still few than existing.
Especially, the tin liquor degree of depth that the present invention designs glass ware forming section 111 overcomes the prejudice of traditional design, have employed the more shallow tin liquor degree of depth, the buoyancy that this kind of tin liquor degree of depth produces meets the needs of float glass completely, bring disadvantageous effect can't to the production of float glass.
The molten tin bath 10 of the embodiment of the present invention substantially reduces the consumption of tin liquor, in float glass, for tin liquor heating and cooling will expend less energy.Decrease tin liquor because of large the brought convection phenomena of the temperature difference simultaneously.
These are only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
