Two, the setting of special-purpose supply channel mechanism, make unit kiln improve the condition of founding, in the I district glass metal is left standstill, the dog-hole front arch has blocked scum silica frost and material skin effectively, glass metal stream not only obtains clarifying homogenizing but also remove the material skin, and the II district can make glass metal obtain effectively lowering the temperature at a slow speed, and the III district can make glass metal obtain insulation, and both sides and middle portion temperature difference are reduced, temperature of glass liquid can effectively be controlled in the processing requirement scope.
Three, the improvement of calendering mechanism structure makes when calendering glass metal crystallization not, thereby makes continuous calendering accomplished.
Four, because the edge of a knife of calendering top roll periodically rolls strip to go out " zanjon ", again through the cutting of double-pole longitudinal cutter structure, the kiln tail can be produced to steady and continuous the qualified sheet material that specification is arranged.
Accompanying drawing 1 is a structural representation of the present utility model,
Accompanying drawing 2 is special-purpose supply channel mechanism structure synoptic diagram,
Accompanying drawing 3 is a calendering formation mechanism structure synoptic diagram.
Below in conjunction with drawings and Examples the utility model is described further.
Admixtion is put into giving in the 2-1 of molten bath of unit kiln 2 by charging device 1, gives 2-1 both sides, molten bath and a pair of well heater 2-4 is housed to admixtion reinforcement heating, makes this place's temperature all reach processing requirement, makes admixtion accelerate fusing.Unit kiln 2 front portions have horizontal flue 2-2 will give the molten bath to separate, the rear portion again with special-purpose supply channel system partitioning, full kiln is implemented all risk insurance temperature, has improved the condition of founding.End in unit kiln 2 ponds is provided with weir 2-3, and melting end and fining end are separated, and has stoped unclean bottom glass to flow into dog-hole, enters forming section.
Clarifying substantially glass metal enters special-purpose supply channel mechanism in weir 3-11 place's overflow.Special use supply channel mechanism is made up of I district, II district and III district.Less than 6m, the pond between two weirs is dark less than the pond at unit kiln 2 other positions deeply apart from the distance of the weir 2-3 of unit kiln 2 ends for the weir 3-11 of unit kiln 2 and junction, I district.Well heater 3-13 and temperature instrumentation 3-1 more than two are housed on top, I district, in its pond both sides uniform two pairs with top electrode 3-12, wherein pair of electrodes is contained in below the dog-hole working hole.Heating by electrode 3-12 in upper portion heater 3-13 and the pond has changed the liquid properties of flow, has eliminated liquid stream dead angle, and glass metal is left standstill, and obtains further clarification and homogenization.Enter the II district by further clarifying high temp glass liquid through dog-hole.
On the top of ingress, II district dog-hole front arch 3-14 is housed, its role is to block effectively scum silica frost, baffle plate 3-15 is equipped with on the top of front arch 3-14, and the two effect is that II district and I district, Dayao are separated fully.Glass metal simultaneously under dog-hole front arch 3-14, the heated by electrodes (see figure 2) is housed, so can not freeze at this.Well heater 3-3 and temperature instrumentation 3-4 are equipped with in top, II district in addition, in its pond uniform two pairs with top electrode 3-16 and temperature instrumentation 3-5.Reduce to the temperature of process stipulation lentamente by high temperature at II district glass metal, also can it be divided into several sub-districts as required, control cooling better with shelves brick, barricade.Cooled glass metal flows into the III district down by floater guide block 3-17.
III district and II differentiation are isolated by shelves brick 3-17 and shelves wall 3-18 in ingress, III district.Electrode 3-19 is controlled in the desired temperature range of moulding the glass metal that flows into this district effectively in the well heater 3-6 on top, III district and the pond, particularly top, III district ad hoc well heater 3-8 opposite side portion heating is controlled in allowed limits the temperature difference of limit portion temperature and middle part temperature effectively.Thereby make the preceding glass metal of moulding reach the chemical uniformity and the thermal uniformity of processing requirement.III district exit end is provided with a grade brick 3-20, and the last end distance top pool wall distance of shelves brick 3-20 is greater than 20mm.Glass metal stream enters calendaring molding mechanism by shelves brick 3-20 overflow.
Glass metal stream descends along 45 °～60 ° the inclined-plane that holds in the palm brick 4-4, and between through top roll 4-2 and the lower roll 4-1, upper and lower roll cools off glass metal rapidly, and with its pulling, is pressed into strip and pulls away.Because holder brick 4-4 bevel angle is big, glass metal is extremely short in this residence time, has little time crystallization and is promptly pulled away.It is arc or polygonal small lugs edge of a knife 4-5 that top roll 4-2 external cylindrical surface upper edge one generatrix direction is provided with a transverse section, and the height of small lugs edge of a knife 4-5 is less than the microcrystal glass plate tape thickness, and small lugs edge of a knife 4-5 two ends and top roll 4-2 two ends are equidistant.Under small lugs edge of a knife 4-5 calendering, form groove on the glass strip 9, prepare for follow-up cutting.
