Description
Technical field
A kind of quartzy technology is the utility model is related to, especially a kind of quartzy melter technology, specifically a kind of shaping
The adjustable crucible lifting formula quartz glass continuous induction melting furnace of area's temperature.
Background technology
The various types of electrical heating continuous induction melting furnaces for being used for quartz glass tube production domestic at present use crucible fixed, earthenware
The heater that crucible periphery tungsten material makes, its common ground is that any cross section of heater is all equal, and this shows in production process
The heat that middle heater is sent is substantially certain in genesis analysis, can not adjust the longitudinal temperature of crucible.Quartz glass tube
Production is in crucible and crucible outlet forming process is：Preheating zone-melting zone-exhaust area-shaping area.Because production is different
Specification kind quartz ampoule rod requires different to the temperature index of overall process, and the particularly requirement to molding zone temperatures is higher.Change
Heater power will change the temperature of preheating zone, melting zone, exhaust area and shaping area, be put down so as to break the heat in crucible Nei Ge areas
Weighing apparatus, causes product quality to decline.Before the cooling that stops production, due to quartz glass, in different temperature sections, its coefficient of expansion is poor from crucible
It is different very big that the quartz glass fusing on crucible top is departed from into crucible, it is necessary to heat, to ensure that crucible is lossless in cooling.Adopt at present
The method taken is to improve power, while continues to complete for quite a long time.
Utility model content
The purpose of this utility model is because crucible is that stationary structure causes shaping area for existing classic continuous induction melting furnace
Temperature is non-adjustable and the problem of quartz ware size can not be adjusted, design is a kind of to be molded zone position by adjusting crucible and is implemented as type
Area's temperature adjustment and then the adjustable crucible lifting formula quartz glass continuous induction melting furnace of molding zone temperatures for adjusting size of pipe and tubing.
The technical solution of the utility model is：
A kind of adjustable crucible lifting formula quartz glass continuous induction melting furnace of molding zone temperatures, it includes crucible 1, body of heater 2, heater
3rd, core bar 4 and mould 5, crucible 1 are arranged in body of heater 2, and heater 3 is electrically connected with main electrode 12 and is wrapped in crucible 1
Outer ring so that the temperature of crucible 1 from top to bottom is in terraced distribution, the lower end of core bar 4 stretched into through bell 6 in crucible 1 and with peace
Mould 5 mounted in the lower end of crucible 1 is relative, and core bar 4 be hollow-core construction, and its upper end is connected so as to earthenware with controlling device of air 7
Conveying protective gas in crucible, it is characterised in that the center of described bell 6 is provided with a through hole, and crucible lifting is provided with the through hole
Seat 20, the upper end of crucible 1 is supported on crucible lifting seat 20, and crucible lifting seat 20 passes through at least three groups on bell 6
Feed screw nut's structure 21 realizes the regulation and positioning of its short transverse in through-holes, and then adjusts core bar bottom and mould
The distance between, realize the regulation of the caliber of quartz ampoule rod 10.
The bottom of described crucible 1 is provided with auxiliary heater 15, and preferably to adjust the temperature of shaping area, the auxiliary adds
Hot device 15 is electrically connected with auxiliary electrode 14.
The length of the core bar 4 is between 2-2.8 rice.
The beneficial effects of the utility model：
The utility model is by the way that crucible is loaded in crucible lifting seat.Coordinate by crucible lifting and with auxiliary heater,
Change shaping offset from and mould temperature, with reach production different size quartz ampoule and rod.Will before blowing out cools
Crucible is reduced, and the shorter time can be used to melt the quartz glass on crucible top and departed from, and ensures that crucible is lossless in cooling.
The utility model can realize the on-line control of quartzy tubing product size, and difference can be realized without changing mould
The shaping of internal-and external diameter allusion tubing, it has the advantages of easy to adjust, temperature is adjustable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：8 be core bar deviation correcting device, and 9 be core bar support, and 11 be charge door, and 13 be body of heater bearing, and 16 be dust-exhausting port,
17 be water jacket, and 18 be high temperature brick, and 19 is husky for insulation.
