Description
Technical field
The utility model relates to a kind of quartz plate continuous induction melting furnace, and particularly a kind of large thickness quartz plate continuous induction melting furnace, belongs to silica glass production unit field.
Background technology
At present, highly purified quartz glass plate mainly adopts quartz continuous melting furnace to produce, traditional quartz continuous melting furnace comprises body of heater, bell, in body of heater, be provided with crucible, between inboard wall of furnace body and crucible, be provided with thermal insulation layer, between crucible and thermal insulation layer, be provided with electric heater unit, in crucible, be provided with core bar, core bar upper end connects a nut through bell, core bar lower end connects a taper platform, and under the continuous draw of plate-drawing machine, the quartz of melting is by taper platform runs down both sides, two stock material streams merge and shrink in centre, form quartz plate.Because a conical surface is respectively established in existing taper platform both sides, in the time drawing the larger quartz plate of thickness, as larger in conical surface slope, the bonding strength in the middle of quartz plate is lower, as larger in conical surface slope, in the middle of lack of fill.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: a kind of large thickness quartz plate continuous induction melting furnace is provided, and bonding strength is good, and steady quality is suitable for the production of large thickness quartz plate.
Large thickness quartz plate continuous induction melting furnace described in the utility model, comprise body of heater, bell, in body of heater, be provided with crucible, between inboard wall of furnace body and crucible, be provided with thermal insulation layer, between crucible and thermal insulation layer, be provided with electric heater unit, in crucible, be provided with core bar, core bar upper end connects a nut through bell, core bar lower end connects taper platform, taper platform is made up of square department, the first tapered portion, the second tapered portion from top to bottom successively, the first tapered portion conical surface slope is less than the second tapered portion conical surface slope, and corresponding crucible bottom is provided with bar shaped outlet.
By the first tapered portion and the second tapered portion are set, the quartz material of original melting is flowed along becoming along the conical surface of two different angles and flow down stage by stage under single conical flow, material stream tentatively shrinks in the first tapered portion, inner fully filling, in the quick cooling contraction moulding of the second tapered portion, both met in conjunction with requirement of strength, and made again inner stuffing abundant, ensured the steady quality of large thickness quartz plate.
Described bar shaped outlet and taper platform running fit, bar shaped outlet length is greater than taper platform length 0～1mm, and length direction does not stay or only stays very little gap, and the contraction moulding of quartz glass plate is mainly carried out from thickness direction, ensures the quality of products.
The second described tapered portion height is that the 1/3～1/2, second tapered portion of the first tapered portion height mainly plays quick contraction, avoids the cooling bonding strength that causes of the time of growing to reduce, therefore highly unsuitable excessive.
The first described tapered portion and the axial angle of core bar are 30 °～60 °, and the axial angle of the second tapered portion and core bar is 50 °～80 °, and both angles are poor can be between 20 °～30 °.
Described bar shaped exit width is greater than 30mm, for the production of large thickness quartz plate more than 30mm.
The quartz of melting flows out and preliminary contraction along the first tapered portion, because the first tapered portion conical surface gradient is less, ensures inner filling, in the time that material stream is left to the second tapered portion, the conical surface larger along gradient shrinks fast, and the material stream of both sides merges in centre, through plate-drawing machine pull-out moulding.Than existing single conical surface, two conical surfaces have ensured bonding strength, make again inner material stream fill fully.
Compared with prior art, the beneficial effect the utlity model has is:
This large thickness quartz plate continuous induction melting furnace, by the first tapered portion and the second tapered portion are set, makes the bonding strength of large thickness quartz plate good, and steady quality, is suitable for the production of large thickness quartz plate.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figures 1 to 3, this large thickness quartz plate continuous induction melting furnace comprises body of heater 1, bell 7, in body of heater 1, be provided with crucible 5, between body of heater 1 inwall and crucible 5, be provided with thermal insulation layer 2, between crucible 5 and thermal insulation layer 2, be provided with electric heater unit 3, in crucible 5, be provided with core bar 6, core bar 6 upper ends connect a nut 9 through bell 7, and core bar 6 lower ends connect taper platform 4, coordinate with nut 9 by core bar 6, the height of adjustable core bar 6, thus taper platform 4 height regulated.Taper platform 4 is made up of square department 401, the first tapered portion 402, the second tapered portion 403 from top to bottom successively, the first tapered portion 402 conical surface slopes are less than the second tapered portion 403 conical surface slopes, the first tapered portion 402 is 30 °～60 ° with the axial angle of core bar 6, the second tapered portion 403 is 50 °～80 ° with the axial angle of core bar 6, and both angles are poor can be selected between 20 °～30 °.The second tapered portion 403 is highly 1/3～1/2 of the first tapered portion 402 height, to realize quick contraction.Crucible 5 bottoms are provided with bar shaped outlet 10, bar shaped outlet 10 and taper platform 4 running fit, and bar shaped exports 10 length and is greater than taper platform 4 length 0～1mm, and bar shaped exports 10 width and is greater than 30mm.
The quartz of melting flows out and preliminary contraction along the first tapered portion 402, because the first tapered portion 401 conical surface gradients are less, ensures inner filling, in the time that material stream is left to the second tapered portion 402, the conical surface larger along gradient shrinks fast, and the material stream of both sides merges in centre, through plate-drawing machine pull-out moulding.Than existing single conical surface, two conical surfaces have ensured bonding strength, make again inner material stream fill fully.
