Description
Technical field
The present invention relates to a kind of quartzy technology, especially a kind of quartzy melter technology, specifically a kind of shaping area temperature
Spend adjustable crucible lifting formula quartz glass continuous induction melting furnace.
Background technology
The domestic various types of electrical heating continuous induction melting furnaces produced for quartz glass tube are fixed using crucible at present, 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, it is impossible to 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 requirement particularly to molding zone temperatures is higher.Change
Heater power will change the temperature of preheating zone, melting zone, exhaust area and shaping area, so that the heat for breaking crucible Nei Ge areas is put down
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 continuing to complete for quite a long time.
The content of the invention
The purpose of the present invention is because crucible is that stationary structure causes molding zone temperatures for existing classic continuous induction melting furnace
It 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 temperature
Degree adjusts and then adjusts the adjustable crucible lifting formula quartz glass continuous induction melting furnace of molding zone temperatures of size of pipe and tubing.
The technical scheme is that：
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 3, 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 the outer of crucible 1
Enclose 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 installed in
The mould 5 of the lower end of crucible 1 is relative, and core bar 4 is hollow-core construction, and its upper end is connected so as into crucible with control device of air 7
Convey protective gas, it is characterised in that the center of described bell 6 is provided with a through hole, crucible lifting seat is installed in the through hole
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 silks on bell 6
Stem nut structure 21 realizes the regulation and positioning of its short transverse in through-holes, so adjust core bar bottom and mould it
Between distance, 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 described core bar 4 is between 2-2.8 meters.
Beneficial effects of the present invention：
The present invention passes through crucible is interior loaded on 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.Crucible is reduced before blowing out cooling,
The quartz glass on crucible top can be melted with the shorter time and departed from, it is ensured that crucible is lossless in cooling.
The present invention can realize the on-line control of quartzy tubing product size, can be realized without changing mould inside and outside difference
The shaping of footpath allusion tubing, it has easy to adjust, the adjustable advantage of temperature.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
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,
