Technical field
The utility model relates to a kind of quartz continuous melting furnace, relates in particular to the continuous induction melting furnace that draws especially big quartzy product.
Background technology
Domestic existing continuous induction melting furnace equipment is made up of body of heater, crucible, heating member, refractory insulating layer, former, opening for feed and discharge pedestal.At present, widely used crucible adopts the tungsten material to make.Because tungsten crucible adopts means such as calcining to make, and at home under the prior art condition, method for calcinating can't be produced the tungsten crucible of bore more than 550mm, thereby also just can not produce quartzy product especially big, that the spy is thick.With gas refining stone roller section and silica tube plain film, production cost was all at 600 yuan/kg, even but also be difficult to produce especially big, special thick quartz plate so in the past.This makes that all China's long-term dependence on import of especially big quartzy product is main.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of quartz continuous melting furnace, can draw out especially big, special thick quartzy product.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of quartz continuous melting furnace, comprise body of heater and be positioned at the intravital crucible of described stove, between described crucible and described body of heater, be provided with refractory insulating layer, between described crucible and described refractory insulating layer, be provided with heating member, bottom at described crucible is provided with discharge pedestal, is provided with the moulding outlet in the center of described discharge pedestal, is provided with former in described crucible, described former upwards joins with core bar, and the bore of described crucible is greater than 550mm.
Wherein, described crucible passes through the roll bending moulding by Mo.
Wherein, the bore of described crucible is 550mm to 800mm.
Further, the size of the moulding of described discharge pedestal outlet is greater than the size of described former.
Further, described former is made by graphite.
Further, described discharge pedestal is made by graphite.
Further, between described body of heater and described refractory insulating layer, be provided with light fire brick.
Further, be provided with bell, on described bell, be fitted with at least one feed-pipe at described body of heater top.
Further, described feed-pipe is more than two, is inserted into evenly and at intervals on the described bell.
After adopting such structure,, thereby also just can produce quartzy product especially big, that the spy is thick because the bore of described crucible is greater than 550mm.
Description of drawings
Fig. 1 is the sectional view of the utility model embodiment quartz continuous melting furnace.
Embodiment
The utility model aims to provide a kind of quartz continuous melting furnace, is used to draw especially big, special thick quartzy product.
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, the utility model embodiment quartz continuous melting furnace, comprise body of heater 8 and the crucible 2 that is positioned at described body of heater 8, between described crucible 2 and described body of heater 8, be provided with refractory insulating layer 4 and light-weight refractory thermal insulation layer 7, between described crucible 2 and described refractory insulating layer 4, be provided with heating member 3, in described crucible 2, be provided with former 5, former 5 upwards joins with molybdenum core bar 1, be provided with discharge pedestal 6 in the bottom of described crucible 2, the bore of described crucible 2 is greater than 550mm, and the bore of the utility model embodiment crucible is 800mm.
After adopting such structure,, thereby also just can produce the thick 3mm of wide 100mm to the especially big quartzy sheet material of the thick 50mm of wide 600mm and the quartzy tubing of bore 300mm to 600mm because the bore of described crucible 2 is 800mm.
On the basis of the foregoing description, further, described crucible 2 passes through the roll bending moulding by Mo, thereby can produce the crucible of bore greater than 550mm, thereby also just can produce especially big, special thick quartzy product.
Further, the bore of described crucible is 550mm to 800mm, and can produce bore is the quartzy product of 550mm to 800mm.
Further, the shape of described former with and the shape of the moulding of described discharge pedestal outlet complement one another, made things convenient for the making of the quartzy sheet material of circular quartzy tubing and rectangle.
Further, the shape of the moulding of described former and described discharge pedestal outlet can be circle or rectangle, can draw quartzy tubing or quartzy sheet material.
Further, the size of the moulding outlet of described discharge pedestal is greater than the size of described former, between the moulding outlet of the quartz raw material that makes continuous thawing by described former and described discharge pedestal the adjustable gap blanking is arranged, make the product stability of drawing and high conformity and scale error little.
Further, described former is made by graphite.Because the life cycle of former is shorter, adopts described graphite former, cost is low, and light weight is upgraded and replaced conveniently.
Further, described discharge pedestal is made by graphite.Because the life cycle of discharge pedestal is shorter, adopts described graphite discharge pedestal, cost is low, and light weight is upgraded and replaced conveniently.
Further, between described body of heater and described refractory insulating layer, be provided with light fire brick.Make described continuous induction melting furnace have crushing resistance preferably.
Further, be provided with bell, on described bell, be fitted with at least one feed-pipe 9 at described body of heater top.In described crucible, add quartz raw material by described feed-pipe 9, can avoid the generation of airborne dust.
Further, described feed-pipe is more than two, is inserted into evenly and at intervals on the described bell.Can make the distribution of quartz raw material in described crucible of adding more even like this.
When making especially big quartzy sheet material, at first select rectangular described former 5 and described discharge pedestal 6, then the high purity quartz raw material is added in the crucible 2 from feed-pipe 9, heating member 3 is carried out persistently overheating, when the temperature in the body of heater 8 rose to 1900 ℃-2300 ℃, it is liquid that the high purity quartz raw material is melted into, when treating the blanking moulding, in monitor procedure,, make it reach the control requirement of required especially big quartzy board dimension by regulating the gap between former 5 and the discharge pedestal 6.By the speed of traction arm-tie machine and adjustment frequency transformer, finally draw out the required technological standard of especially big quartzy sheet material simultaneously.By changing circular described high purity graphite former 5 and high purity graphite discharge pedestal 6,, just can produce especially big quartzy tubing and special thick quartzy tubing according to above-mentioned production stage.
